Smart speakers and broadcast radio

Smart speakers like the Amazon Echo are outselling traditional radios

The traditional radio broadcast industry are finding that the smart speaker as a threat to their business models.

This is because that there are more Amazon Echo, Google Home or similar smart speakers being bought than traditional radio sets. It is in addition to us using smartphones that don’t have traditional broadcast-radio tuners as our “go-to” information and entertainment devices.

Although these smart speakers can, at your voice command, pull up a traditional radio station thanks to TuneIn or similar Internet-radio directories, an increasing number of users are using them to summon podcasts or music playlists through the various podcast and music-on-demand services.

At the moment, traditional radio whether through traditional broadcast technology or Internet streaming is primarily being listened to in the car or at businesses we frequent. It is also being seen, whether for information or entertainment, as a valid casual-listening content-source by Generation X (people born from the late 60s to the early 80s) and prior generations thanks to it being seen that way for a long time. This is due to the ubiquity of increasingly-affordable radio sets in many different form factors along with radio stations making a strong effort to keep listeners tuned to their output.

It is although advertisers and others have seen and are seeing the younger generations as “where the money is”. Here, they end up sponsoring podcasts or playlists to reach that audience with their message in order to stay relevant.

ABC Radio Podcasts

The ABC, like other traditional broadcasters, are offering their own podcasts, whether to do with an existing radio show or not

But what can be or is being done about this? At the moment, traditional radio stations are creating podcasts, whether as a byproduct of an existing radio show or as a new product. Similarly as I have experienced, most radio stations are planting their regular broadcast output on the Internet and making sure this still happens so as to work with smartphones and smart speakers. It is even though they face battles with music rightsholders and sporting leagues about international streaming rights for music or sports content.

RadioDNS “hybrid radio” has surfaced as a way to bring together traditional radio and the Internet. The key method offered by this platform is through a “single-dial” approach that provides a seamless handover between local radio frequencies / DAB multiplex locations and Internet streams for the same radio station.

Reliance on Internet audio streams as often done with smart speakers and smartphones can be problemsome if you don’t have the right kind of network and Internet connection. This represents the typical home or small-business network connected behind most home / small-business routers.

You will run in to problems with setting up a smart speaker or similar device to work with a headline public-access / guest-access Wi-Fi network that depends on Web-based authentication or having these devices work with an enterprise-grade network that uses per-device-based authentication approaches. It also includes dealing with mobile broadband services that charge an arm and a leg for continual bandwidth use but services that operate in a highly-competitive market may make this factor easier.

Similarly broadcast-radio technology tends to appeal to listenership on battery-operated devices because the technology associated with it is optimised to work for battery efficiency. It is due to the broadcast-radio technology working on a one-way approach to receiving the radio signals rather than being dependent on a two-way transceiver demanded of Wi-Fi or mobile-broadband.

What can be done to bridge these technologies

One approach would be to have an Internet radio that also receives radio content via broadcast technologies work with at least one of the common voice-driven home assistant platforms.

This can be in the form of the radio working alongside a smart speaker based on the common platforms and using RadioDNS to pull up local radio stations under voice control.

An Internet radio can also serve as a speaker for online audio resources like on-demand music services, podcasts and Internet radio especially if the radio doesn’t have network-audio / Internet-radio functionality. The latter concept is being underscored with the Google Assistant platform where you can direct audio from an online-audio service to a device that supports the Google Chromecast protocol. Even if the radio has network-audio / Internet-radio functionality, it could be part of a voice-driven home-assistant platform, which a lot of manufacturers are heading towards and can be of relevance for the “big sets” like hi-fi systems and the network multiroom audio platforms.

A cheaper option could implement RadioDNS across a Bluetooth link with the voice-driven home assistant platform handling the RadioDNS logic. It may require the creation of a Bluetooth profile for sending RadioDNS-specific data between the radio and the smart speaker’s platform i.e. a set-appropriate pointer to the station on the broadcast bands.

It can also be about an Internet-radio / smart-speaker combination device, like the many combination devices available over the years that integrated radio reception and at least one other function. Such a set would have the ability to be an Internet radio but it would have a microphone array and a button to activate Amazon Alexa or Google Assistant, whereupon you would have the full “smart speaker” abilities of an Amazon Echo or Google Home speaker. As well, it would tie in with the RadioDNS functionality to pull up stations on the local wavebands as if you are pulling them up using the assistant’s Internet-radio functionality.

Conclusion

To keep the classic radio medium going, the manufacturers, broadcasters and other stakeholders need to look at whatever technologies can be used to make it relevant in this day and age.

Consumer Electronics and Personal IT trends for 2020

Every year in January, the Consumer Electronics Show is run in Las Vegas, USA and this show does give a glimpse in to what trends will affect consumer electronics and personal IT. In most cases, these are products that will be on the marketplace this year or products that are a proof-of-concept or prototype that demonstrates an upcoming technology.

The problem is that this exhibition focuses on what will be available in North America but a lot of the technology will be relevant to the rest of the world. In a lot of these cases, localised variants will appear at various trade shows or PR events that occur in Europe or other areas.

As well, the trade-show circuit will attract service-level information-technology companies who don’t need to make hardware or have a hardware platform, or be a content creator. Here, it will be simply about the provision of IT-based services as part of a ubiquitous computing environment including the concept of experience-driven computing.

Connectivity Technology

Over the past year, the two main technologies that were called out regarding online connectivity or the home network were 5G mobile broadband and Wi-Fi 6 (802.11ax) wireless local networks. This is about very-high-bandwidth wireless data communications whether out and about or within your home or other small network.

As various radiocommunications regulatory agencies around the world “open up” the 6GHz waveband for Wi-Fi network use with the USA’s Federal Communications Commission the first to do so, the Wi-Fi Alliance have created a specification identifier for network equipment working this waveband. Here, it is known as Wi-Fi 6E as a way to identify the fact that the device can work the 6GHz waveband, and is in contrast to Wi-Fi 6 (802.11ax) devices that only work the 2.4GHz and 5GHz wavebands.

One of D-Link’s Wi-Fi 6 routers that also supports Wi-Fi EasyMesh – setting the standard for home network technology this year

Both these technologies became real with an increase in client devices or small-network infrastructure hardware supporting at least one of these technologies. This included laptop computers and smartphones having this kind of functionality baked in to them as well as more home-network routers, distributed-WI-Fi systems and range extenders being equipped with Wi-Fi 6. There is even the fact that some of the network-infrastructure vendors like Linksys and NETGEAR are offering routers that combine both technologies – 5G mobile broadband as a WAN (Internet) connection and Wi-Fi 6 as a LAN (local-network) connection.

A step in the right direction for distributed-Wi-Fi networks was to see major home-network brands offer routers and/or range extenders compliant to the WI-Fi EasyMesh standard. This allows you to create a distributed Wi-Fi network with equipment from different vendors, opening up the market for equipment from a diverse range of vendors including telcos and ISPs along with a pathway towards innovation in this space.

Bluetooth hasn’t been forgotten about here with the new Bluetooth audio specification being “set in stone” and premiered at CES 2020. This specification, known as Bluetooth LE Audio, works on the Bluetooth Low Energy profile and supports the LC3 (Low Complexity Communications Codec) audio codec that packages the equivalent of an SBC audio stream used by Bluetooth audio setups in half the bandwidth. This allows for longer battery runtimes which will also lead to smaller form-factors for audio devices due to the reduced need for a larger battery.

It also supports multiple independent and synchronous audio streams to be sent from one source device to many sink devices. This strengthens use cases like hearing aids that work with Bluetooth and may supersede the inductive loop as a technology for assisted-listening setups. As well, the multiple-streaming technology will be a boon to applications like multichannel Bluetooth speaker setups; or Bluetooth headphones as part of assistive audio, multilingual soundtrack options or semi-private listening arrangements.

The Bluetooth LE Audio technology is to be released in the first half of 2020 with compatible devices being on the market by 2021. But there will also be the issue of having device support for this technology being baked in to operating systems as a class driver.

Dell XPS 13 2-in-1 Ultrabook - USB-C power

USB 4 will be the next stage for hardware connectivity and will include Thunderbolt 3

As for wired peripheral interconnection, USB 4.0 will be surfacing as a high-speed connection standard for computers and mobile devices. There will be compatibility with Thunderbolt 3 due to Intel signing over the intellectual property rights for that protocol to the USB Implementers Forum. But this may be used by some computer vendors as a product differentiator although the market will prefer that USB 4 computers and peripherals work with those that use Thunderbolt 3. Let’s not forget that the physical connector for USB 4 will be the Type C connection.

Let’s not forget that newer Android phones will use USB Power Delivery as the official standard for transferring power from chargers or powerbanks to themselves. This is about avoiding the use of proprietary fast-charge technologies and using something that is defined by the industry for this purpose.

Computer trends

Lenovo IdeaPad Creator 5 15″ clamshell prosumer / content-creator laptop

At the moment, as I outlined in the article about “prosumer” content creators being identified by computer manufacturers as a significant market segment, this year is being seen as a time to launch performance-optimised computers targeted at this user group. These units will be optimised to work with popular content-creation software in a sure-fire manner.

Let’s not forget that Lenovo is tying up with NEC in order to create the LAVIE computer brand that targets mobile professionals. This was after Toshiba spun off their laptop-computer division as “Dynabook” brand then sold it to Sharp; and Sony sold off their VAIO computer brand with it existing as a premium computer brand. But is this symbolic of what the Japanese computer names are heading towards where they focus on creating premium business laptops and tablets.

As well as offering their newer-generation CPUs, Intel has demonstrated that they can offer their own high-performance personal-computer display infrastructure. They even demonstrated a graphics card that use Intel-designed discrete GPU technology. This leads towards them competing with NVIDIA and AMD when it comes to discrete graphics-infrastructure technology and could lead to a three-way race in this field.

It is alongside AMD placing a lot of effort on their Ryzen CPUs which are leading towards them in a position to effectively compete on a par with Intel’s Core CPUs. As well, Intel and AMD could head towards creating performance computing setups that are based around their CPUs and discrete graphics infrastructure technology, including setups that have the CPU and discrete GPU on the same silicon.

There is also an increase in the number of “Always Connected PCs” that run with ARM RISC microarchitecture rather than the traditional Intel i86/i64 CISC microarchitecture. They will be about operating on batteries for a very long time and have 4G, if not 5G mobile-broadband modems with classic SIM or eSIM service authentication. Most likely I would see them as being the direction for portable mainstream business computing.

For gaming, Dell has premiered a budget gaming-grade laptop that uses an AMD Ryzen CPU and an AMD Radeon graphics processor but is styled like their other “G Series” gaming laptops. As well, Lenovo took an interesting step with one of their gaming laptops by using Intel integrated graphics processors for its graphics infrastructure while equipping it with a Thunderbolt 3 port. Here, the user is to buy an external graphics module, typically the Lenovo BoostStation card-cage unit which is their first product of its kind that they released, to have the machine perform at its best. What this is about is a trend towards creating an entry-level performance laptop product range, very similar to buying the increased-performance “GT” variant of a popular family car model.

Another trend that is being shown frequently is multiple-screen or folding-screen portable computers. This is being promoted by Intel and Microsoft in the context of Windows 10X and newer Intel chipsets. It is being driven by the multiple-screen or folding-screen smartphone that Samsung and others are on the verge of releasing as finished products. But this technology will have a limited appeal towards early adopters until it is seen as legitimate by the general user base.

As far as small-form-factor desktop computers are concerned, Intel is working towards a modular “next unit of computing” platform which has the whole computer system on a card the same size as a traditional PCI expansion card. This platform, known as Ghost Canyon uses the “Compute Element” which is the user-swappable card, is intended to bring hack the joys of us upgrading a computer’s performance by ourselves even if we go for a smaller computer platform.

Connected-TV technology

This year has heralded interest in 8K UHDTV which has effectively twice the resolution of 4K UHDTV. As well, the 8K Association has been formed in order to set standards for domestic 8K UHDTV applications and promote this technology.

It is in conjunction with ATSC 3.0, also known as NextGenTV, being premiered at CES 2020 as a new direction for free-to-air TV in the USA. It us being valued thanks to people moving away from cable and satellite pay-TV services towards Netflix and other video-on-demand services augmented by free-to-air TV. Here, it will allow Americans to benefit from 4K UHDTV and Dolby Atmos technology via the TV antenna. Like with DVB and HBBTV-based standards used in Europe and Oceania, this technology combines the over-the-air signal with broadband Internet data to achieve advanced TV experiences.

There is also increased robustness as far as antenna-based reception is concerned which may allow for use of indoor antennas without their associated problems. As well, mobile users will benefit from this newer technology for on-the-road viewing. But there will also be an emphasis towards broadcast-LAN operation with one tuner offering a broadcast signal amongst multiple TVs. Users can upgrade their existing televisions to this technology by connecting an ATSC 3.0 set-top box to their TV as they see fit, but there will be some TVs, most likely “living-room” models from a few manufacturers, that will support this standard.

The 4K AMOLED screen is entering the “Goldilocks” territory when it comes to product price and screen size – not too big and expensive, not too small or cheap, but just right. It is seen by the trade as a “mid-market” territory but, for a TV, it is about something that appeals to more people without being too ostentatious or requiring one to pay a price’s ransom.

The advantage it has over the LCD screen that rules this market territory is to have increased contrast and richer colours, something that those of you who have a smartphone or tablet with an OLED display benefit from. As well, it is a technology that legitimises the high-dynamic-range and wide-colour-gamut video reproduction technology being pushed by the film and video industries.

Here, Sony released the first 48” 4K AMOLED screen that would be able to fit most viewing areas. This includes apartments and small houses as well as use in bedrooms, or secondary lounge areas including living rooms which aren’t frequently used for watching TV. As well, some AMOLED TV manufacturers are pitching sets that cost under US$1000. Here, this price point puts the AMOLED TV within reach of most middle-class families who are considering upgrading to this kind of technology without paying a price that sounds too vulgar.

Another trend affecting TVs is support for variable high refresh rates. Here, it appeals towards games consoles being able to work with game-optimised variable-refresh-rate monitors typically partnered with PC-based desktop gaming rigs, offering the same kind of display refresh rate as the display card on a gaming-rig PC would offer. This is being factored in because the large-screen TV is being valued in the context of gaming, especially with one-machine multiple-player games or the excitement of playing a favourite game on that big screen.

As well, I see the Apple TV and Android TV platforms as dominant smart-TV / set-top-box platforms due to the existence of strong code bases, strong developer communities and a well-nurtured app store. Here, the Android platform will appeal to TV vendors who haven’t invested in a smart-TV platform along with some third-party set-top box vendors. But the Android TV platform as a set-top-box platform has to be disassociated from the so-called “fully-loaded” Android boxes that are sold online from China for access to pirated TV content.

This is being driven by an avalanche of video-on-demand services that will appear over this year. Some of these will be subscription-based and offer new original content produced by the service’s owner while others will use advertising, perhaps as part of a freemium arrangement, and work heavily on licensing deep back-catalogue material. There will also be an effort amongst the new video-on-demand providers to take an international approach, appearing in multiple markets around the world, most likely with the goal of licensing content in all international markets concurrently.

It will even lead to each content-production name having its own video-on-demand service that primarily hosts content from its stable. But the question that will come about is how many video-on-demand subscriptions will we be having to budget for and maintain if we want content that reflects our choices.

Audio Technology

The DAB+ digital broadcast radio platform is increasing its footprint within Europe and across some parts of Africa and Asia. It includes some European countries like Norway and Switzerland moving their broadcast infrastructure away from AM and FM radio to this technology.

Pure Sensia 200D Connect Internet radio

Pure Sensia 200D Connect Internet radio – a representative of the current trend towards the “hybrid radio” concept

Here, it would be about an increased variety of devices that have broadcast-radio reception functionality based on this platform, including those that have Bluetooth and/or Internet-radio functionality. As well, more vehicle builders are being encouraged to supply DAB+ radios as factory-standard in all of their vehicles. Let’s not forget that value-priced DAB+ and Internet radio equipment will be equipped with a colour display that shows things like station branding or album cover-art while you listen to that station.

RadioDNS will be something that facilitates a hybrid broadcast-broadband approach to broadcast radio. This will include the ability to switch between broadcast-radio channels and an Internet radio stream for the same radio station or allow for richer supporting content to appear on the set’s display. It can also be about a “single-dial” approach to finding stations on broadcast and Internet bands. But RadioDNS has been given more “clout” in to the USA due to it being able to work with AM, FM or HD Radio (IBOC digital radio on AM and FM) which is used there.

Sonos’s partnership with IKEA, the furniture store who sells furniture that you assemble yourself with an Allen key, is demonstrating that a high-end multiroom-audio platform can be partnered with a commodity retail brand. What it could lead to is an incentive to build these kind of platforms around a mixture of premium, value and budget units, allowing for things like a low-risk “foot-in-the-door” approach for people starting out on that platform or people who have the premium equipment building out their system with cheaper equipment in secondary listening areas. It could even put pressure on the industry to adopt a common standard for multiroom-audio setups.

The streaming audio-on-demand scene is moving in a manner as to shore itself up against Spotify. Initially this is about offering either an advertising-supported free limited-service tier as what Amazon and Google are doing, or to offer a premium service tier with a focus on CD-quality or master-quality sound which is what Amazon is doing. But it could easily go beyond the “three-tier service” such as improved playlists, underrepresented content, support for standalone audio equipment, and business music services. As well, your ISP or telco could be providing access to a streaming-audio service as part of their service package or you buy a piece of network-enabled audio equipment and benefit from reduced subscription rates for an online music service.

The headphone scene is setting some strong contenders when it comes to excellent value-for-money for noise-cancelling Bluetooth headsets.

Bose initiated this battle with the QuietComfort 35 II headphones with the technological press’s reviewers seeing them as a standard setter for this class of headset. Then Sony introduced the WH1000XM3 headphones and these were seen on a par with the Bose cans but at a more affordable price with some press using terms like “Bose-killers” to describe them. Bang & Olufsen came in to the party and offered a premium noise-cancelling Bluetooth headset known as the Beoplay H9. But lately Bose also answered Sony by offering the Noise Cancelling 700 headset that effectively did that job in a minimalist form. This is while Sony are intending to launch the WH1000XM4 this year to raise the bar against Bose and their current product.

As far as “true wireless” active-noise-cancelling earbuds are concerned, Apple with their AirPods Pro and Sony with their WF1000XM3 have established themselves at the top of the pack for excellence. What I see of this is someone else could answer them to achieve that same level of excellence especially at a value price. This product class is also likely to benefit from the Bluetooth LC Audio specification due to the requirement for a small battery in each earbud and the small size of each earbud.

What Apple, Bose, Sony and B&O are highlighting is that they could easily compete with each other to achieve excellent products when it comes to headphones you use with your laptop, smartphone or tablet. It could even be a chance for other companies to join in and raise the bar for premium everyday-use headset design, including the idea of having audiophile headphone qualities in this class of headset.

Voice assistant platforms and ambient computing

Amazon Alexa and Google Assistant will still bring forth newer devices, whether in the form of speakers or displays. But Amazon Alexa and Microsoft Cortana will be part of the Open Voice Initiative allowing the same physical hardware to handle multiple voice assistant platforms.

A question that will arise through this year is whether there will be a strong direction towards having these devices work as a fixed audio or video telephony endpoint. This is whether the device works in a similar fashion to the classic landline telephone service with its own number; or as an extension to a smartphone that is part of a mobile telecommunications service.

The voice-assistant platforms will end up becoming part of an ambient computing trend that is underscored by facilitators like Internet of Things and distributed computing. Here, it is about computing that blends in with your lifestyle rather than being a separate activity.

As far as the Internet Of Things is concerned, the Connected Home over IP protocol was set in stone. This effort, facilitated by Amazon, Google and Apple with the oversight of the Zigbee Alliance, is about an IP-driven Internet-Of-Things data transport architecture. The idea is to do away with protocol gateways which were being used with various smart-home applications but the manufacturers were goading consumers to use their own protocol gateways with their devices rather than a third-party solution. There will be an emphasis on a safe secure interoperable Internet-of-Things network.

Data security and equipment maintenance in our personal and business lives

The Social Web will be considered a very important part of our lives with us primarily benefiting from it on tablets, smartphones or highly-portable laptops.

But it will still be a key disinformation vector. One of the new methods expected to be exploited this year is the creation of deepfakes. These are audio and video items created using artificial intelligence to make it as though a person said something when they didn’t. There will even be the ability to make the voice or face of a deepfaked person appear older or younger than they were when they were recorded, while make the voice or face appear as fluid as that of a real person.

Here, it will be used as a cyber weapon to create political, social and business instability by these representing our leaders whether they be in government, business or other circles. The deepfake will also be of value as a phishing tool in order to make the threat or plea appear to be more authentic to the victim.

As well, ransomware will begin to take on a network-wide dimension and affect business and service availability. Sensitive data, whether of a personal or business nature, will end up becoming the bargaining chip for ransomware hackers. This is in contrast to access to a computer user’s data resources which was often the case with ransomware.

The Internet Of Things will also be considered a continual security risk especially due to poor software and firmware quality control. It will lead to a conversation regarding the maintenance of our online devices through their lifecycle, including making sure they are running software that is stable and secure.

Then there is the “end-of-support” issue where a manufacturer ceases to show interest on older online devices that are currently in use. That is a question that is surfacing when one invests a significant amount of money in to the devices and people don’t want to throw out older equipment just because the manufacturer doesn’t want to support it anymore. It also goes against the grain of the post-Global-Financial-Crisis attitude most of us have adopted where we don’t want to support a throwaway society but want to see what we buy exist for the long haul.

The Sonos debacle raised the issue about what level of functionality the user should expect from their device along with how platform-based setups consisting of legacy and newer devices should behave. It also raised the issue of keeping the device’s software stable and secure.

Conclusion

This year will be considered a very interesting time for our online life as we see improvements to existing technologies along with newer conversations about how system-based technologies continue to evolve with a secure stable mindset.

Using Bluetooth as part of the hybrid radio concept

Pure Sensia 200D Connect Internet radio

Pure Sensia 200D Connect Internet radio – a representative of the current trend towards the “hybrid radio” concept

Previously, I have covered the concept of “hybrid radio” which is being put forward by RadioDNS. This is about integrating the reception of audio-based radio content from a radio station either through the traditional analogue or digital broadcast technologies or through the Internet.

It is based on the common Internet-radio application where traditional radio stations transmit a simulcast of their broadcast output as an Internet stream. You would experience this with an app like TuneIn Radio or by using an Internet radio, of which I have reviewed many. This has been used to listen to overseas radio stations by those of us who like the “vibe” of a particular country or to learn a new language, but has been used as a way to hear a national radio station that isn’t received in one’s local area, a situation that is common in rural Australia.

It is intended to provide automatic switching to an Internet-based simulcast of the radio station if you are out of the reception area for a broadcast transmitter and you can’t be “handed over” to a better transmitter’s output of the same station. It is also underscored by the concept of a “single-dial” tuning approach to select stations without worrying which broadcast methodology they are using, whether traditional or Internet-based. here is also the availability of richer metadata that can be shown on screens that support rich graphic displays along with an electronic programme guide for radio broadcasts.

This functionality is dependent on the radio having Internet connectivity of some sort. It is typically with the set being equipped with Wi-Fi or Ethernet connectivity for use on a small network, or a car radio being equipped with a mobile-broadband modem provisioned with mobile-broadband service.

This may not work properly with enterprise or public-access networks that require authentication beyond a Wi-Fi passphrase or WPS-PBC setup or we have to make sure the mobile-broadband service is provisioned for the car radio that we are using in the way the radio expects. This was something I had come across when someone posted a question about attempting to use the Internet capabilities of the Sony CMT-MX750Ni Internet-capable bookshelf music stereo system with a “headline” public-access Wi-Fi network in the place they were living in.

As well, the Internet connectivity is offered by consumer-electronics manufacturers as a product differentiator with it typically ending up on the premium products in the range. Similarly, some manufacturers want to steer clear of Internet-connectivity as a feature for their consumer-electronics product ranges.

But an increasing number of radio sets and audio equipment are implementing Bluetooth technology typically to allow streaming of audio content from mobile devices paired with the set. In the car-audio scene, this is to facilitate a safe hands-free telephone setup that allows the driver to keep their hands on the wheel and eyes on the road.

USB-C connector on Samsung Galaxy S8 Plus smartphone

Smartphones or tablets could be used to provide “hybrid-radio” functionality

The RadioDNS hybrid-radio concept could be extended to the Bluetooth link by a standard application-level class or profile for the Bluetooth specification. Here, this would work in conjunction with a computing device that runs companion “hybrid-radio” software and is linked to the radio via Bluetooth in order to enable full “hybrid-radio” functionality.

This could allow for broadcast station selection using the companion device or the display of rich metadata for the currently-listened-to station on the companion device’s display irrespective of the source of the metadata. This would be of benefit to those sets that can’t show rich graphic metadata such as what DAB+ or Digital Radio Mondiale are capable of.

The concept cam make use of the voice-driven home assistants like Amazon Echo or Google Home for many options. Here, it would exploit the idea of having a device like Amazon Echo or Google Home provide the Bluetooth – Internet bridge to your small Wi-Fi network and play network-hosted or Internet-hosted audio content through the radio’s speaker. It would be important where the radio’s amplifier and speaker does a better job at reproducing music compared to what the Amazon Echo or Google Home device.

… as could devices like the Lenovo Smart Display

For example, you could ask Alexa or Google Assistant to select a station and the local broadcast signal will then play. Or if you use something like Google Home Hub, you could have the station’s audio coming through the radio while a graphically-rich interface for that station appears on the Home Hub’s screen.

What RadioDNS needs to look towards is the idea of using Bluetooth or similar peripheral-level connections as a way of allowing a companion computing device to facilitate hybrid radio functionality for equipment or use environments that don’t support integrated Internet connectivity.

What is the “hybrid radio” concept all about?

Pure Sensia 200D Connect Internet radio

Pure Sensia 200D Connect Internet radio – a representative of the current trend towards the “hybrid radio” concept

There is some interest in the concept of “hybrid radio” as a possible trend to affect broadcast radio in the online era.

Regular readers of this site will have seen reviews that I have done of Internet radios. These are radios and audio equipment the can pull in audio content via Internet-radio streams and, in most cases, local broadcast radio delivered via FM, AM and/or DAB+ digital radio. This is in addition to access to various online audio services like Pandora or Spotify or DLNA-capable content hosts on your home network.

The Internet-radio streams may be programs only available via the Internet or simulcasts of radio content broadcast in the radio station’s broadcast area using the traditional methods. They are usually selected through a directory like TuneIn Radio, Radioline or vTuner and their appeal has been to allow access to radio content via devices that only have Internet connection like smartphones, or to provide access to “out-of-area” radio content. This latter factor has a strong appeal for expats, language learners or people with a soft spot for a particular city or country including those of us who like a particular radio talent or programme available in that area but not locally.

It is also being augmented through access to podcasts or on-demand audio through the various Internet-radio directories or through online audio services, with most of the broadcasters making their own podcasts or similar content that they produce.

But there are efforts being taken towards improving the user experience for this class of device, especially where a set is capable of receiving content through traditional broadcast radio and the Internet. The typical user experience is to provide Internet radio as its own “band” or “source” on these devices.

The RadioDNS organisation is behind these “hybrid radio” efforts as a way to make the traditional radio become relevant to the Millennial generation who lives by their iPhones. It is also bringing the Internet radio concept towards automotive use, especially in a simplified manner that keeps the driver’s hands on the wheel and eyes on the road as much as possible.

“Single-dial” tuning

One of the goals is to provide a “single dial” approach for locating radio stations. This is where you can see a list of local or overseas broadcasters and the set tunes in to that broadcast using the best method available for that broadcast.

Here, the set would choose the local broadcast medium if its radio tuner determines that the signal is strong enough for reliable reception, otherwise it would choose the Internet stream. It would also take advantage of the “follow this station” functionality in FM-RDS or DAB+ to choose the closest strongest transmitter for that station, something that would be important for national or regional radio networks with many transmitters or local stations that run infill transmitters to cover dead zones in their area..

There will be the ability to search for stations based on certain criteria like location, content genre, or station identifier, a feature that every one of us who uses a DAB/DAB+ digital, RDS-capable FM or Internet radio have benefited from. But this will be augmented by logo-driven browsing where the station’s familiar logo is shown on the set’s display or station logos appear as part of a station list.

The preset-station concept where you have access to your favourite stations at the touch of a button is augmented by the “single-dial” tuning process. Here, each preset-station space, represented by a button or menu list item, would point to a station and when you select that station, the set would choose the best method of receiving it whether broadcast or Internet.

It could then lead towards the idea of grouping radio station presets in order to suit particular users’ station preferences or occasion-based station lists. An example that comes to my mind where this feature would earn its keep is a close friend of mine who had regularly looked after some school children through the school holidays.

Here, the friend personally liked serious radio content like classical music or talk radio from the public-service radio stations. But when these children travelled with her, they listened to the local commercial (private) FM stations that ran pop music because they listened to these broadcasters when they are at home or in the car with their parents. In this situation, it could be feasible to allocate one preset group to the serious radio content and another to the popular-music stations, then call up this group when the children are travelling with the driver.

Such a feature will be considered highly relevant for automotive and portable receivers because these sets are more likely to move between different reception conditions. As well, it leads towards broadcasting and programming approaches that are totally independent of the medium that is being used to carry the broadcast programme.

A rich radio-listening experience

Once you are listening to your favourite programme, the “hybrid radio” experience will be about augmenting what you are listening to.

A news broadcast could be supplied with a written summary of the key items in that bulletin. Similarly, a weather report could benefit from visual information like a map or a chart that shows what the weather will be like over a time period. Even traffic reports could be augmented with maps that show where the traffic jams or closed-off roads are, giving you a fair idea of where possible rat-runs could be taken.

Talkback and other deep-reporting shows could benefit from links to online resources that are relevant to what is being talked about.  It could even be feasible to “throw” contact details like hotline numbers or studio lines to one’s smartphone using one or more methods like a QR code shown on the set’s display.

Let’s not forget that the “hybrid radio” concept can also be about gaining access to these kind of shows in an “on-demand” manner similar to podcasts. This could even allow a person who heard one of these shows to set things up so that future episodes of the show can be saved locally for listening at one’s convenience. If the station primarily syndicates this content from other producers like podcasters or content-producing organisations for their own broadcast, they could then use the “hybrid radio” arrangement to allow listeners to find the shows as on-demand material.

For music radio programmes, there would be the ability to show the details about the song or piece of music currently playing. Some vendors could take this further by implementing a Shazam-style “buy this” option for the current track in conjunction with one or more “download-to-own” music stores, or to replay the song through an “online jukebox” like Spotify.

There is the ability for advertising-driven radio stations to allow their advertisers and sponsors to offer more than the 30-second radio commercial. Here, they could provide weblinks to the advertiser’s online resources so listeners can act on the advertised offers. This can also extend to online couponing or the ability to book one’s place at a concert or music festival that an artist whose song is currently playing is performing at.

Conclusion

The “hybrid radio” concept could be about simplifying access to radio broadcasts in a media-independent manner then allowing listeners to get the best value out of them.
