Wi-Fi CERTIFIED HaLow (Product Page)

My Comments

A Wi-Fi network technology that is being put on the map at the moment is Wi-Fi CERTIFIED HaLow a.k.a Wi-Fi Halow.

This network technology is based on IEEE 802.11ah wireless network technology and works on the 900MHz waveband. It is about long-range operation of approximately 1 kilometre from the access point and very low power operation that allows devices to run for a year on commodity batteries like a single 3V coin-size cell or a pair of AA-size Duracells.

The power requirement may be a non-issue for devices like HVAC thermostats that are wired to the heating system they control. But they may be an issue with devices like movement sensors or smart locks that are dependent on their own battery power. As well, the low power requirements that Wi-Fi HaLow offer could be of benefit towards devices that implement energy-harvesting technology like solar power or kinetic energy.

This low-bandwidth Wi-Fi specification is intended to complement the other Wi-Fi specifications used with your home or business network. But it is focused towards the Internet of Everything especially where the devices are to be operated across a wide radius like a farm or campus.

The network topography for a Wi-Fi HaLow network segment will be very similar to the standard Wi-Fi network. That is where multiple client devices link to an access point, but there should be the ability for a mobile device to roam between access points associated with the same Wi-Fi network.

Compared to the likes of 802.15 Zigbee, Z-Wave, DECT-ULE, Bluetooth LE and similar Internet-of-Things wireless technologies, this is meant to avoid the need for special routers when there is a desire to link them to IP-based networks.

This is because this technology effectively uses the same protocol stack as our Wi-Fi networks save for the layers associated with the radio medium. It also means that the same security, connectivity and quality-of-service protocols that are part of Wi-Fi nowadays like EasyConnect and WPA3 can be implemented in Wi-Fi HaLow devices.

At the moment, you would need to use a Wi-Fi HaLow access point to get any Internet-of-Things devices on to your network and the Internet. It may be a small device that plugs in to your existing home network router or network infrastructure. But a subsequent Wi-Fi access point or router design could have built-in support for this standard thus making it more ubiquitous.

The use cases being positioned for Wi-Fi HaLow technology would encompass the smart home, the smart building and the smart city where all sorts of “Internet-of-Things” devices are acting as controllers or sensors. It is also encompassing vertical use cases like agriculture, industry and medicine where sensors come in to play here.

At the moment, this kind of connectivity will exist as an alternative to Zigbee, Z-Wave and similar technologies especially where IP-level connectivity and functionality is wanted at the device. It may not have ready appeal in use cases where a direct connection to Internet-based technology may not be required.

On the other hand, a use case could allow for a “hub and spoke” approach to the Internet of Things where a device can connect to accessory peripheral devices using Zigbee or Bluetooth but link to the home network and Internet via WI-Fi HaLow. An example of this could be a retrofit-install smart lock which supports the use of accessory input devices like keypads, NFC card/fob readers and contact sensors.

Wi-Fi HaLow could be seen as a direction towards capable low-power long-distance wireless networking for Internet of Things, especially where direct Internet / LAN network connectivity is desired out of the application.

My Comments

Qobuz is a music service that was founded in France in 2007. This service offers sobscription-based music streaming and transactional download-to-own music purchasing but offers these services with Hi-Fi-grade sound. It had existed in Europe for a long time and since 2020, Australians and New Zealanders can use this service to stream or purchase high-quality music.

Here, the music is available using lossless streaming and file formats with CD-quality audio as a baseline and the option for master-grade audio. There is also the ability to download a PDF copy of the album’s liner notes which typically will have lyrics for an album’s songs or a biography and discography in the case of a artist-specific compilation.

The Studio Premium subscription costs AUD$24.99 per month or AUD$229.99 per year which offers up to “master-grade” streaming quality. There is also a more expensive Studio Sublime+ subscription tier costing AUD$299.99 per year which gives you a discounts for “download-to-own” music tracks that you purchase.

There are native clients for Windows, Mac OS, Android and iOS along with the ability to interact with Qobuz through the Web. The Android and iOS apps allow streaming of Qobuz audio through the Apple AirPlay or Google Cast (Chromecast) to endpoint devices compatible with these protocols. Issues that were raised include the desktop apps for Windows and Mac OS regular computers not being available through the operating systems’ native app stores. This may be of issue where the app stores are preferred by some users as a software update path.

Qobuz can work with Naim equipment

As far as other devices are concerned, there is support for Sonos speakers and some network-capable hi-fi equipment, usually some of the premium hi-fi brands like Sony, Yamaha, Linn or Naim. But none of the popular games consoles, smart speakers or smart TVs don’t support Qobuz yet in a native manner.

But the omission of synchronous lyrics or music videos on Qobuz is more about focusing this service to music listening.  This is similar to how most of us would be listening to our music whether on packaged media like vinyl or CD; or as file-based audio and we either want it in the background or to concentrate on the actual music.

There will still be calls for interlinking Qobuz, Deezer and Tidal with music-recognition services or the Shazam or Soundhound kind so people who hear songs on the radio for example can bring them up on these high-quality services. Similarly, there will be the need to make curated playlists available across multiple platforms through the use of a standard datatype and export / import abilities.

At least Qobuz is coming to the fore as a high-quality file-based audio service that offers both a subscription-based streaming approach and a transactional download-to-own approach for your music.

How could CD-quality lossless audio be marketed when it comes to streaming

Sony MAP-S1 network CD receiver

A strong direction for music streaming services is to offer CD-quality sound for all of their library at least

Apple, Amazon and Spotify are lining up or have lined up hi-fi-grade service tiers as part of their audio-streaming services. It is in response to Tidal and Deezer already offering this kind of sound quality for a long time along with the fear of other boutique audio-streaming services setting up shop and focusing on high-quality audio.

Now there is something interesting happening here regarding hi-fi-grade streaming. Here, Apple is having a CD-grade lossless-audio service as part of their standard premium subscription while making sure all music available to their Apple Music streaming service is CD-quality.

So how could these streaming music services compete effectively yet serve those of us who value high quality sound from those online music jukebox services that we use?

What are these hi-fi-grade digital audio services about?

Spotify Windows 10 Store port

This will be something that is expected of Spotify at least

The hi-fi-grade service tiers typically offer a sound quality similar to that of a standard audio CD that you are playing on your CD player, with the same digital-audio specifications i.e. 44.1 kHz sampling rate and 16-bit samples representing stereo sound. Some of these services may offer some content at 48 kHz sampling rate that was specified for the original DAT audio tapes and may be used as a workflow standard for digital radio and TV.

In the same way that a regular audio CD stores the audio content in the original uncompressed PCM form, these hi-fi-grade streaming services use a lossless data-compression form similar to the FLAC audio filetype to transmit the sound while preserving the sound quality. That is equivalent to how a ZIP “file-of-files” works in compressing and binding together data from multiple files.

CD-grade digital audio was adopted during the late 1980s as the benchmark for high-quality sound reproduction in the consumer space. As well, the DAT tapes that recorded 16-bit PCM audio at 44.1 or 48 kHz sampling rates were considered the two-channel recording standard for project studios and similar professional audio content-creation workflows. It is although MiniDisc which used a lossy audio codec caught on in the UK and Japan for personal audio applications.

Some of these services offer extras like surround-sound or object-based audio soundmixes or supply the audio at “master-grade” specifications like 96 or 192 kHz sampling rates or 24 or more bits per sample. But these are best enjoyed on equipment that would properly reproduce the sound held therein to expectations. This is while most good audio equipment engineered since the 1970s was engineered to work capably with the audio CD as its pinnacle.

The provision of these hi-fi-grade services is having appeal thanks to telcos and ISPs offering increased bandwidth and data allowances for fixed and mobile broadband Internet services. This is more so in markets where there is increased competition for the customer’s fixed or mobile Internet service dollar.

As well, there is a highly-competitive market war going on between Bose, Apple and Sony at least for high-quality active-noise-cancelling Bluetooth headsets with the possibility of other headset manufacturers joining in this market war. This is something very close to the late-1970s Receiver Wars where hi-fi companies were vying with each other for the best hi-fi stereo receivers for one’s hi-fi system and increasing value for money in that product class.

Here, a streaming music service that befits these high-quality in-ear or over-the-head headsets could show what they are capable of when it comes to sound reproduction while on the road.

Let’s not forget that Apple and others are working on power-efficient hi-fi-grade digital-analogue-converter circuitry for laptops, tablets, smartphones and other portable audio endpoint devices. Then hi-fi-grade digital-analogue-conversion circuitry that connects to USB or Apple devices is being offered by nearly every hi-fi name under the sun whether as a separate box or as part of the functionality set that a hi-fi component or stereo system would offer.

Current limitations with enjoying hi-fi-grade audio on the move

There are limitations with this kind of service offering, especially with the use of Bluetooth Classic streaming to headphones or automotive infotainment setups from mobile devices. At the moment, it is being preferred that a wired connection, whether via a traditional analogue headphone cable or via an external digital-analogue converter box, is used to run the sound to a pair of good-quality headphones while “on the road”.

Similarly, Apple’s and Google’s smartphone-automotive-integration platforms need to be able to support use of these hi-fi-grade audio services properly so you can benefit from this class of sound when you are at the wheel of your car.

What could be done?

One step that can be taken by many music-streaming services is to create a service-level distinction between CD-quality stereo lossless audio service and create a higher-grade extra-cost audio services that focus on “master-grade” or multichannel soundmixes.  Here, most of us like our music in stereo sound and see CD quality sound as the pinnacle with equipment engineered to that calibre. This is while the esoteric audiophiles would invest in equipment and services that can handle master-grade audio or multichannel soundmixes.

The music services could them move towards offering the CD-quality stereo lossless sound as the audio quality for the standard paid service subscription. That includes moving the service’s music library towards that kind of quality. The user would need to have the ability to enable and disable the CD-quality lossless stereo sound on a device-by-device basis perhaps to cater for smartphone use or limited bandwidth.

Where a music service offers transactional “download-to-own” music, the recordings could be offered at CD quality stereo as lossless files. There could be the ability to provide a complementary download of previously-purchased material as the CD-quality stereo lossless files.

At the moment, there are a number of open-frame and proprietary paths that are able to use a home network to transmit CD-quality or master-quality lossless digital audio from a computing device or streaming audio service to audio endpoint devices within the home. But there needs to be more done to support mobile and portable setups where one is likely to hear audio files while out and about.

The Bluetooth SIG could investigate how CD-quality lossless audio can be sent wirelessly between devices using the various audio profiles that they oversee. This is more so as Bluetooth is used primarily to send multimedia audio from a smartphone or tablet to speakers, headphones or home and car audio equipment. Here, it could be based on their Bluetooth LE Audio specification which is being used to revise the Bluetooth multimedia audio use case effectively.

Similarly, the use of USB-C as a “digital audio path” from a computing device to an audio-output device needs to be encouraged. This would come in to its own with connecting to audio devices or systems that have highly-strung digital-analogue conversion circuitry which can come in to its own with high-quality audio streaming services.

In the automotive context, Apple CarPlay and Android Auto which are used to provide integrated smartphone-dashboard functionality could be improved to provide lossless audio transfer between the smartphone and the car’s infotainment system. This may be valued as a differentiator that can be applied to premium car-audio setups.

Once there are a list of standard protocols adopted for streaming lossless hi-fi grade stereo sound to headsets and automotive setups and that support wired and wireless connectivity, this could make proper CD-quality stereo sound more relevant on the road.

IKEA introduces new SYMFONISK picture frame WiFi speaker (Press Release)

My Comments

IKEA have added another speaker to their Sonos-based SYMFONISK multi-room speaker lineup, continuing their idea of an affordable path to the Sonos network multi-room audio platform. These work in the same way as Sonos speakers and you can establish a Sonos-based multi-room audio setup based on a mix of Sonos or IKEA SYMFONISK speakers and use your home network’s Wi-Fi segment to transmit the sound.

The previous SYMFONISK speakers came in the form of a traditional bookshelf speaker and a table lamp. But this latest product has been described as appearing in the form of a picture frame but you have to use IKEA’s decorative art panels for these speakers. Here, it is more about the front of these speakers serving as the speaker grille that allows the sound to come out.

These speakers are able to be mounted on a wall or can stand on a table. But the framework and legs that allows them to stand on a table is designed to allow them to reproduce sound without adding extra vibration or noise to that sound as what is expected for a speaker enclosure.

There are hardware buttons on the IKEA SYMFONISK wall-art speakers to adjust the volume and start or stop the music with. But you use the Sonos mobile-platform apps or desktop software to choose what you want to hear through these speaker.

It is expected for IKEA to sell the SYMFONISK wall-art speakers for US$199 each with replacement wall-art fronts for US$20 each. But it will be interesting to hear whether these speakers can displace the SONOS One when it comes to sound quality

From what I have seen, it seems like IKEA have bothered to stay on with the Sonos-driven SYMFONISK network multiroom audio platform if they have bothered to design and market another SYMFONISK speaker. But it could mean that people who use the Sonos multiroom audio platform could be buying these IKEA speakers to build out their setup in a cost-effective manner.

My Comments

Over this past year, a South-African song with Zulu lyrics ended up becoming a musical symbol of hope through this COVID season.

This song, “Jerusalema”, was recorded in 2019 by Master KG but when it appeared online in 2020 along with a set of associated dance moves, it became very popular. There were a series of dance challenges where individuals or groups of people performed the dance associated with this song and uploaded music videos of their performances.

It was all concurrent at the time when the COVID-19 coronavirus plague was an unknown quantity and governments implemented measures to limit the spread of this virus. Such measures manifested in the form of border and travel restrictions, stay-at-home orders and lockdowns; mask-wearing and social-distancing mandates; amongst other things.

At the same time, there was Donald Trump and Jair Bolsonaro who were treating this pandemic with contempt and creating disdain against these necessary public health restrictions and the medical-research races for treatments and vaccines. Even the act of honouring one or more of these public-health measures became politically-charged within the USA.

It was also aggravated by the death of George Floyd at the hands of American police offices which brought on the Black Lives Matter protest movement. This movement also highlighted how divisive things were within the USA when it came to civil rights and the treatment of marginalised minorities in that country and was aggravated by Donald Trump’s behaviour during the protests.

The song, its music and the associated dances conveyed a comfortable “feel-good” vibe along with a thread that unites the various communities of people whether “over-the-wire” using the Internet or face-to-face where the various restrictions allowed it. This helped with boosting public moral through this season. There was also a celebration of the survivors and of survival.

Let’s not forget the Zulu-language lyrics and the associated melody were conveying a message of escapism from the continuing barrage of bad news we were facing. This is very much like how other catchy popular music songs played by oneself during hard times can be seen as a form of escapism.

As well, “Jerusalema” has caused us to show interest in Afrobeat and placed Africa on the popular-music map. This follows on from the way African-heritage diasporas have contributed to popular music over the past century and a bit through the form of jazz, funk, soul, disco and similar musical styles along with musical techniques like rapping and breakdancing.

YouTube and similar services are replete with videos of these dance challenges done by various groups of people. There are even some European airlines who have had aircrew groups perform this dance and make a video in the name of the airline as a way of saying that we will be back in the air again. The Irish Gardai national police and the Swiss federal police each had some officer teams within their forces create similar videos as an effort to boost public morale within their nations.

There are also some videos existing on YouTube about how to perform the dance routine associated with this song. These resources can be worth referring to if you want to know how to perform the dance.

“Jerusalema” and its associated dance routine will be seen in the same light as some of those songs which had or acquired their own dance routines that market out particular years or eras. Think of songs like “YMCA” by the Village People; “Forever” by Chris Brown with its wedding-dance video; “Macarena” by Los Del Rio; or “Vogue” by Madonna.

But it will also continue to be seen as a song of hope for the COVID-19 season just like Gloria Gaynor’s “I Will Survive” became a song of hope through the 1970s or John Lennon’s “Imagine” being a song of hope through the Vietnam War era.

German government subsidises Starlink satellite Internet

German government to subsidise satellite Internet installations for Starlink and similar setups at the consumer end

Germany readies subsidies for satellite internet providers such as Starlink | Reuters

My Comments

The rise of low-earth-orbit satellite technology to enable decent Internet service for regional, rural and remote parts of the world has gained a bit more traction.

This time, it is the German Federal Government (Bundesregierung) with its Transport ministry who are subsidising Starlink installations across rural Germany. The US’s FCC has engaged in some form of subsidisation for Starlink but this is at a corporate level as part of their US-government-based program for enabling decent rural Internet service there.

The German approach is to provide EUR€500 towards Starlink hardware purchase for installation in Germany’s rural areas. This doesn’t just apply to Starlink but to any satellite or other radio-link-based Internet service provided on a retail level. It is intended to be consumer-focused and provider-agnostic in the same manner as what is expected for the provision of broadcasting and telecommunications in modern Germany.

It doesn’t apply to ongoing service costs that customers pay to keep the service alive. In the case of Starlink, the monthly service costs are EUR€99 / month at the time of writing.

.. to improve access to real broadband in German rural areas

This was just announced as Tesla were about to commence work on building its European Gigafactory near Berlin and was riding on the fact that Tesla and SpaceX Starlink are owned by Elon Musk. The Bundesregierung need to seek approval from all of Germany’s 16 Federal States for this retail-level subsidy to go ahead.

The question that will come up is  whether public subsidies for satellite or other radio-based Internet service is the way to go to bring decent broadband Internet to rural areas. This is compared to current efforts by local or regional governments in cohort with local chambers of commerce to bring fibre-optic Internet to rural and regional areas.

There will also be the issue of whether to extend this kind of subsidy to people living in boats along Germany’s inland waterways. Think of retirees who have riverboats on the Rhine, Elbe or Wupper rivers or cabin cruisers on the likes of Lake Constance (Bodensee).

Personally, I would see Starlink and similar technology come in to play for sparse rural areas while fibre or similar deployments are considered for more dense settlements. The long fibre-optic trunk link between towns or to serve a remote employment / industry area should never be forgotten as a way to encourage economic growth along its path.

At least Germany is taking another approach to dealing with the rural Internet deficiency issue by subsidising the installation of Starlink and similar technology in its rural households.

When should you consider upgrading your home network router?

Broadband router lights

There are situations that will occur which will require you to replace your home network’s router

How to tell when it’s time to upgrade your router – CNET

My Comments

There are factors that may drive you towards upgrading your home network’s router at some point in its life. Here, you may think that it is still performing adequately for your current needs including your current Internet service level.

You may find that when you sign on to a new Internet service, you may be offered a new Wi-Fi router for your home network as part of the deal. In most cases, this may see you through quite a number of years with your service. But on the other hand, you may choose a “bring-your-own-router” option for your new Internet service so you could keep your existing equipment going for the long haul. But going down that path may not be ideal unless you intend to use up-to-date equipment that can support your new Internet service and current computing devices to the best it can.

Reliability

If you find yourself frequently turning your network’s router and modem off and on to reset your Internet connection, this may be an indicator that your equipment is on its last legs. A good indicator would be if you are on average doing this routine more than once a week.

Another factor to observe is whether your online experience has degraded especially with multimedia content that you are streaming or when you engage in videocalls. Look for situations like excessive buffering or stalled connections that can indicate your router is becoming unreliable.

Speed

You may want to make sure that you are taking advantage of the bandwidth you are paying for so you get your money’s worth.

This would be important if you are upgrading to a service tier that offers more bandwidth for example. For that matter, you may find that after two or three years on the same service plan, you may be aware that your telco or ISP is offering a deal that has more bandwidth for the same price you are currently paying.

Another factor is how sluggish is your home network. This may be noticed with use of network-based media setups like AirPlay or Chromecast yielding substandard performance or print jobs taking too long when you print via your home network. Similarly, it can be noticed if you have many people in your household or business and the network’s performance is sub-par while they use it at once especially for multimedia.

If you Internet connection is provided using a separate modem and router setup, you may want to check if the router is at fault by connecting a computer to the modem directly via Ethernet and using that to assess speed and latency.

Network Security and Software Quality

You may find that some devices like the FritzBox 5530 Fiber will have continual firmware updates and keep themselves secure

Another factor that may be worth considering is whether the router’s vendor is supplying regular firmware updates for your unit. This is important in relationship to bugfixes or patches to rectify security exploits discovered within the firmware.

This factor is important due to data-security issues because a bug or security exploit within the router’s firmware can increase the risk of a cyberattack on the network or its devices.

Some vendors may continue to supply software-quality and security updates for their older equipment but cease to provide feature updates that add functionality to these devices. But you have to be careful where the vendor ceases to supply any updated firmware after they have declared end-of-life on that device.

Newer network technology arriving

Telstra Smarty Modem Generation 2 modem router press picture courtesy of Telstra

Newer routers like the carrier-supplied Telstra Smart Modem 2 are most likely to be engineered for today’s Internet service and home network expectations

Increasingly your Internet service may be upgraded to newer technology in order to allow for faster throughput. It is something that will be continuing to happen as Internet service providers increase capacity and speed for newer use cases and applications. You may even find that you have to upgrade your home network router if you are revising your Internet service or moving premises to an area with better Internet service.

If you are using a modem router and you upgrade your Internet service to something that uses newer technology, you may have to replace the modem router with different equipment that supports the new technology properly.

In the case of some fibre-copper setups like fibre-to-the-node, fibre-to-the-cabinet or fibre-to-the-basement that implement DSL-based connectivity, you would have to make sure the modem-router can support the latest DSL specifications fully and properly for that link. Here, a lot of older DSL modem routers support ADSL2 at the best but you need equipment to work with VDSL2 or G.Fast links that a DSL-based fibre-copper link would use.

In some cases, the installation may require the use of a separate modem connected to a broadband router that has an Ethernet WAN connection. Examples of this would include satellite, fibre-to-the-premises or most cable-modem installations.

As well, you may want to improve your network’s speed and security. This is more so with Wi-Fi networks where you may find that you have relatively up-to-date smartphones, tablets and computers on your network. In this case, you would be thinking of Wi-Fi 5 or 6 with WPA2-AES or WPA3 for security.

Distributed Wi-Fi

NETGEAR Orbi with Wi-Fi 6 press picture courtesy of NETGEAR

You may even be considering the use of a distributed-Wi-Fi setup like the NETGEAR Orbi to increase Wi-Fi coverage

Another thing worth considering is whether to implement distributed-Wi-Fi technology a.k.a mesh Wi-Fi to increase coverage of your home network’s Wi-Fi segment across your home or small business.

But most distributed-Wi-Fi setups are dependent on working with equipment sold by the same vendor. That is unless the equipment supports Wi-Fi EasyMesh which offers a vendor-independent approach. At the moment, there are still some early teething points with the EasyMesh standard with some vendors not running with software that is polished for true interoperability.

Most systems that support this functionality may have the ability to work as access points for an existing router or as broadband routers in their own right. You may also find that some home-network routers, especially some of the units made in Europe like the AVM FritzBox devices can support distributed Wi-Fi after a firmware upgrade.

This solution may come in to its own if you are thinking of bringing your home network up-to-date by replacing an old router that uses very old technologies on the LAN side.

Conclusion

If you are dealing with a very old home-network router that is becoming very unreliable or slow, you may have to look at these factors when considering whether to replace that router with a newer unit.

USB-C to allow 240 watts power for gaming laptops

Gaming notebooks should get their own USB-C chargers soon – PC World Australia (idg.com.au)

My Comments

Since I had bought my Dell XPS 13 9300 laptop computer, I had found that the charger that Dell supplied with that laptop was able to charge my Samsung Galaxy S8 Android phone quickly. It is in addition to this charger being an external power supply for use with this laptop when it’s away from my desktop and the Dell WD19TB Thunderbolt dock used as the hub there. This is thanks to both devices implementing the USB-C connection and USB Power Delivery specification.

But if you are using a gaming laptop, you will have found that you have to use a highly-powerful power supply to charge that computer up or run it from the mains. Dell had used some sort of proprietary kludge to allow some of their high-performance business computers to work with their WD-19 series of USB-C and Thunderbolt docks.

Dell WD19TB Thunderbolt dock

and docks similar to this Dell WD19TB Thunderbolt 3 dock will support that class of computer in a “single-cord” manner independent of whoever manufactures the host computer product.

Now the USB Implementers Forum have revised the USB-C Cables and Connectors standard to version 2.1. This creates an “Extended Power Range” class of cables and power supplies which has been scoped in to the USB Power Delivery specification. It allows the delivery of 48 volts at 5 amps but is required to support 50 volts at 5 amps at the most.

Effectively this is to extend the power supply capability for a USB Power Delivery setup to 240 watts and will apply to all USB and Thunderbolt standards that implement the same physical and electrical connection.

What kind of benefit will this achieve? It will be about high-performance computers like gaming laptops benefiting from a “single-pipe” connection that also supplies the power these computers need. It will also open up the market for cheaper higher-powered power supplies that can serve these computers no matter the power-source kind (AC mains power, DC automotive power or battery packs). This will be facilitated more with the use of GaN power electronics in these power supplies which will allow for highly-compact designs.

Some also see the idea of the USB Extended Power Range cables being able to power computing peripherals like 4K monitors or inkjet printers. In the case of 4K monitors, it may be about reducing the number of power outlets needed to power a multi-screen computing setup where some of the screens work at that resolution.

Could this also open up an extra feature for gaming-ready 4K TVs?

But I also see the idea of home-entertainment equipment like 4K gaming-ready TVs or home-theatre receivers being equipped with USB-C sockets that support PD to the Extended Range level along with DisplayPort alt connectivity.

Here, this would come in to its own where one cable powers a gaming laptop while running video and audio from that laptop to the TV’s screen or, in the case of home-theatre equipment, a connected TV or projector. The benefit here would be a “quick-to-connect, quick-to-disconnect” setup when it comes to using that big-screen TV in the main lounge area for playing games.

At least the USB Extended Power Range addition to the USB-C Cable and Connectors specification will underscore the idea of making sure that the USB Type-C is the universal multipurpose connector for today’s tech life.

For that matter, I had bought the Dell XPS 13 9300 laptop and the WD-19TB Thunderbolt dock at a discount from Dell thanks to my reviewing of some of their computer equipment on this site.

My Comments

Apple’s up-and-coming Apple TV 4K is to capitalise on the idea of using set-top and smart-speaker platforms to provide enhanced stereo sound or home theatre setups that they, Google and Amazon are dabbling in.

Here, it is about using the smart speakers as a means to play the sound from video content streamed through the Apple TV, Amazon Fire or Google Chromecast with Google TV set-top devices. This is about either using a pair of like smart speakers to provide increased stereo separation for the video content’s sound. As well, it can be about using a smart speaker for remote listening to the video content’s sound.

As well, there have been approaches towards having various video peripherals offer their own audio output abilities usually for their own sources along with soundbars and the like implementing HDMI-ARC to play TV audio through their own speakers, In some cases, some of the soundbars that are part of network multiroom speaker platforms have the ability to stream sound from the TV to one or more remote speakers.

But Apple is bridging their Apple-TV/AirPlay/HomePod set-top and smart-speaker platform with HDMI-ARC technology including the eARC revision to do more. This time, it is to allow a user to stream audio from the TV’s own sources such as the broadcast-TV tuner to Apple HomePod speakers. This can be about remotely listening to a sports call or 24-hour TV news channel via a HomePod speeaker or using a pair of HomePod speakers to have better stereo separation for your favourite TV shows.

At the moment, this is intended to work with the original HomePod speakers rather than the HomePod Mini, with this causing confusion in the press as Apple is discontinuing the original HomePod speakers. The question that will come up is whether this kind of setup will apply to other AirPlay-compatible devices connected to your Apple TV 4K set-top box, including an AirPlay-based multiroom setup which your Apple TV device is part of.

This could have Amazon and Google looking towards ARC / eARC support for their set-top devices with the idea of playing TV audio via their Echo or Home / Assistant smart-speaker products.

As I mentioned in my article about video peripherals offering audio-output abilities, there will be the issue of using HDMI-ARC and HDMI-eARC more for delivering TV audio to these devices and how that can be improved upon. For example, I would see a requirement for an “any-HDMI-socket” approach to ARC/eARC connection rather than connecting the ARC-capable audio peripheral to one particular HDMI socket. Similarly, a TV may have to support streaming TV-show sound to multiple HDMI-ARC ports concurrently as well as passing PCM or bitstream audio streams representing surround sound to multiple HDMI-ARC ports.

But I am surprised that Apple supports HDMI-ARC with their Apple TV 4K device and HomePod smart speaker setup which would facilitate access to traditional broadcast TV via their equipment. That may be considered “out of touch” by some of the trendy Apple fanbois who aren’t necessarily in to the traditional way of consuming TV content. But I do see this as a significant trend in bringing traditional TV to smart-speaker platforms especially where a company owns a set-top media player platform and a smart-speaker platform.
