Newer iterations of the XBox One to have connectivity for WISA-compliant speakers

Wireless speaker support could be coming to Xbox One consoles | Windows Central

My Comments

An increasing trend for video-peripheral devices like set-top boxes and games consoles is to offer an ability to connect speakers or headphones directly to these devices even though these devices are normally seen as video source devices. This goes against the conventional wisdom of a TV, soundbar and / or home-theatre receiver serving as the audio destination device for a home AV setup.

But what of Smart TVs being able to pass audio to these devices?

For example, Humax are offering a Bluetooth A2DP audio output on their premium PVRs so that the soundtrack from whatever you are watching on the PVR’s “current” tuner or hard disk can be fed through a Bluetooth headset or speaker. Just lately, Microsoft partnered up with the WISA Association to provide wireless-speaker output through WISA-compliant speakers from subsequent XBox games-console designs.

Let’s not forget that some soundbars and audio amplifiers are equipped with one HDMI-ARC connection for the TV and don’t add a video source to the home AV setup. The same situation also encompasses a large number of popularly-priced DVD and Blu-Ray home-theatre systems that only have one HDMI-ARC connection for the host TV as the only way to connect video equipment to these systems.

The limitation that is being shown up here is that you can’t stream the soundtrack of video content through the speakers or headphones connected through these devices’ Bluetooth or wireless-speaker outputs unless you are viewing the content hosted by the device itself. Or you may find it difficult to watch what you want yet hear it in the manner that suits the situation such as via headphones or a better speaker setup.

This is very similar to the old practice of connecting a video recorder’s audio output to a hi-fi amplifier to pipe the sound from either a TV broadcast or a videotape through the better-sounding hi-fi speakers.  There were even some video recorders that had their own headphone amplifiers or users simply connected them to hi-fi amplifiers or similar devices with integrated headphone outputs in order to add private or late-night listening abilities to that TV which wasn’t equipped with a headphone output. In that case, you only had access to the video recorder’s tuner or its tape transport through the hi-fi system with the video recorder offering some advantages over what was integrated in that old TV.

It may not be seen as a limitation except if a video peripheral connected to the TV or the TV’s own abilities provide content different to what is available in the “speaker-ability”-equipped video peripheral.

But what can be done to improve upon this reality would be for TV and video-peripheral manufacturers to answer this trend in an improved way.

Use of HDMI-ARC input functionality for host-TV audio

One way would be for the video-peripheral vendors who provide this kind of Bluetooth / WISA or similar “speaker output” ability to implement HDMI-ARC connectivity on their device’s HDMI output socket. It is very similar to the approach used by a popularly-priced DVD or Blu-Ray home-theatre system which only has one HDMI socket,

This means that if the device is connected to the ARC-capable HDMI socket on the TV, it can stream the sound from the TV’s own tuner, “connected-TV” functionality or video peripherals connected to the other HDMI inputs on the TV through this device’s “speaker output”.

Here, you may have to use the device’s controller to select “TV audio” to hear the sound associated with the TV’s sources through the Bluetooth speaker for example. But some TVs that implement this system properly may offer an “audio output” option on the audio menu so you can direct the sound to the audio-capable device by selecting that device rather than the TV’s internal speakers.

The TV to support multiple HDMI-ARC video peripherals

A TV could also implement HDMI-ARC across multiple HDMI sockets to cater for multiple video peripherals that support this functionality. It would come in to its own where different video peripherals use different connection methods for audio devices or you use a soundbar or home theatre setup equipped with a single HDMI connection alongside one of these video peripherals.

Here, you would have the ability to direct the sound to one or more of the HDMI-ARC devices instead of or in addition to the integral speakers.

The first application that one may think of would be to provide late-night private listening using a pair of Bluetooth headphones connected to a cable box, or to switch to WISA-capable speakers connected to a newer XBOX rather than hear the sound through the TV’s speakers. On the other hand, the setup could allow the concurrent operation of multiple audio outputs such as to use a Bluetooth headset connected via a cable box and run at an independent volume level for someone who is hard of hearing while everyone else in the room hears the TV content through the TV’s or home-theatre’s speakers.

In both situations, it would be desirable to hear whatever source is connected to the TV such as a Blu-Ray player or a network media player through the Bluetooth headphones connected via the Bluetooth-capable cable TV box.

How should the digital audio be delivered?

A question that can be raised is how the digital audio is to be delivered to the different HDMI-ARC devices.

This can affect whether to run a stereo or surround soundmix for the content’s soundtrack; whether the soundtrack should be delivered as a Dolby Digital / DTS bitstream that the HDMI-ARC audio device decodes or as a PCM bitstream already decoded by the TV or source video peripheral; or simply whether to stay within the “CD/DAT-quality” digital parameters (16 bit 44.1kHz or 48kHz sampling rate) or allow “master-grade” digital parameters (24 bit 96kHz or 192kHz sampling rate).

This situation may be determined by the destination audio device’s abilities such as whether it can decode Dolby Digital or DTS audio or if it can handle digital audio at “master-grade” bitrates. Similarly, it may also be about achieving a common specification for all of the connected devices, including whether and how to concurrently provide multiple audio streams for the same content such as to offer a two-channel soundmix and a multichannel soundmix.

This can lead to situations like supplying multiple soundmixes of a kind via HDMI-ARC in order to make situations like multilingual audio, audio description or selectable commentary work well for different viewers. Similarly, it could be feasible to offer a “surround via headphones” binaural soundmix like Dolby Headphone to Bluetooth headsets connected to a cable box while offering a full surround soundmix through a multiple-speaker home theatre setup.

Conclusion

What will eventually be raised is what can be achieved at a common baseline specification, including issues of processing power and HDMI bandwidth that the setup can handle. This is especially if a device like a games console or set-top box is working as a content source and audio sink while the TV works as an audio “hub”.

It is more so where we are expecting that flat-screen TV, especially one installed in a secondary lounge area, being required to become an AV hub for all of the video peripherals that are connected to it.

eGFX Breakaway Puck (Product Page, Press Release)

My Comments

Increasingly there has been the rise of external graphics modules that connect to your laptop or small-form-factor desktop computer via its Thunderbolt 3 port. This has allowed this class of computer to benefit from better graphics hardware even though they don’t have the ability for you to fit a graphics card in them. Similarly, they would appeal to users who have an ultraportable computer and mainly want the advanced graphics in a particular environment like home or office but don’t care about it on the road.

A highly-portable approach to giving the Dell XPS 13 Kaby Lake and its ilk discrete graphics

But most of these devices have come in the form of a “card-cage” which houses a desktop-grade graphics card, which is all and well if you are thinking of using gaming-grade or workstation-grade desktop graphics hardware. As well, these “card-cage” units would take up a lot of space, something that may not be beneficial with cramped desktop or entertainment-unit spaces.

Acer previously issued one of these external graphics modules which has an integrated NVIDIA graphics chipset but Sonnet has now come to the fore with the eGFX Breakaway Puck that uses integrated AMD Radeon graphics silicon. This device is sold as two different models with one equipped with the AMD Radeon RX560 GPU and another with the better-performing Radeon RX570 GPU.

The Sonnet eGFX Breakaway Puck can be stuffed in to a backpack’s pocket this making it appeal to users who are likely to be travelling more. As well, they offer a VESA-compliant bracket so that this external graphics module can be mounted on a display stand or arm for those of us who want as much space on the desktop as possible.

Connectivity for external displays is in the form of 3 DisplayPort outlets and 1 HDMI 2.0b outlet to cater for multi-monitor setups. It also exploits the Power Delivery standard to supply up to 45W of power to the host computer which can mean that you don’t need to use the computer’s charger to power the host computer.

There could be some improvements regarding connectivity like having another Thunderbolt 3 / USB-C port for connection to other peripherals, something that can be of concern with ultraportables that use very few connections. But I would see this opening up the idea for similarly-sized integrated-chipset external graphics modules both as highly-portable “add-ons” for laptop computers or to create “building-block” approaches to small-form-factor “NUC-style” desktop computer setups.

BBC introduces interactive radio drama using Alexa

Amazon Echo and similar voice-driven assistants will end up being able to provide voice-driven interactive storytelling

BBC launches interactive voice drama for Amazon Alexa devices | CNet News

My Comments

Any of you who have lived in the UK or other British Commonwealth countries will be familiar with the BBC’s long-time expertise with radio plays. Examples of these include the unforgettable humour of the Goons or the long-evolving countryside drama that is the Archers. If you didn’t hear it on the BBC, you may have heard one of these dramas via a resource available through the Internet or a local public radio station syndicated one or more of the BBC radio plays, making it available to hear through your trusty radio. These are essentially comedy and drama that is delivered through an audio-only medium.

But the BBC are combining this old-time craft of theirs and the concept of the “Choose Your Own Adventure” books to provide an interactive audio drama that you effectively participate in using, at the moment, the Amazon Alexa platform.  “The Inspection Chamber” is a science fiction comedy where you effectively are playing the “extra character” in the show to steer its plot.

It will also be very similar to those text-based adventure games made available through mainframe computers and early home-computer platforms but this effort will be about having a wider vocabulary and natural-language handling.

But I see this as a way to take voice-driven assistants further in the direction of providing entertainment in the form of “Choose Your Own Adventure” interactive storytelling. This could lead to other radio-drama houses and, to some extent, education / training environments taking this concept further to provide voice-driven interactive stories, such as to provide scenario-driven training or language learning.

AMD now launches the Ryzen processor for portable computing

Articles – From the horse’s mouth

AMD

Ryzen Processors (Product Page)

My Comments

Just lately, Intel released their 8th generation Kaby Lake R family of “Core i” processors which are targeted at portable computers. These powerful CPUs that were optimised for portable use were issued with an intent to compete against AMD’s upcoming release of their Ryzen processors, pitched at a similar usage scenario. Various press articles even drew attention towards being able to play more powerful PC games on these lightweight computers rather than limiting their scope of activity.

Now AMD have released this silicon which also integrates the Radeon Vega graphics-processing silicon for the laptop market. This is where they are targeting the Ryzen 7 2700U CPU and the Ryzen 5 2500U 15-watt processors and instigating a race against Intel’s Kaby Lake R horsepower and QHD integrated graphics.

What I see of this is that Intel and AMD will make sure that this generation of ultraportable computers will be seen to be more powerful than the prior generations. Think of using an Intel Kaby Lake R Core i7 or AMD Ryzen 7 powered 2-in-1 for most photo-editing tasks or as a “virtual turntable” in the DJ booth, activities that wouldn’t be associated with this class of computer.

At the moment, Intel hasn’t licensed the Thunderbolt 3 connectivity standard across the board including to AMD, which will see it as a limitation when it comes to allow users to upgrade graphics capabilities on their AMD Rysen-equipped laptops using an external graphics module.

One way Intel could approach this is to divest the Thunderbolt standards and intellectual property to an independent working group like the USB.org group so that manufacturers who implement Intel, AMD, the ARM RISC-based vendors like Qualcomm or other silicon can use Thunderbolt 3 as a high-throughput external connectivity option. This could be a way to establish an even playing field for all of the silicon vendors who are providing processor power for all the various computing devices out there.

At least Intel and AMD are taking steps in the right direction towards the idea of mixing portability and power for computing setups based on regular-computer platforms. It may also make this kind of performance become affordable for most people.

Another attempt at security for the Internet Of Things

Article

Google and others back Internet of Things security push | Engadget

My Comments

An issue that is perplexing the personal-computing scene is data security and user privacy in the context of dedicated-function devices including the Internet Of Things. This has lately come to the fore thanks to the KRACK WPA2 wireless-network security exploit which mainly affects Wi-Fi client devices. In this situation, it would be of concern regarding these devices due to the fact that the device vendors and the chipset vendors don’t regularly update the software for their devices.

But ARM Holdings, a British chipmaker behind the ARM RISC microarchitecture used in mobile devices and most dedicated-function devices has joined with Google Cloud Platform and others to push for an Internet-Of-Things data security platform. This is very relevant because the ARM RISC microarchitecture satisfies the needs of dedicated-function device designs due to the ability to yield greater functionalities using lean power requirements compared to traditional microarchitecture.

Here, the effort is centred around open-source firmware known as “Firmware-M” that is to be pitched for ARMv8-M CPUs. The Platform Security Architecture will allow the ability for hardware / software / cloud-system designers to tackle IoT threat models and analyse the firmware with a security angle. This means that they can work towards hardware and firmware architectures that have a “best-practice approach” for security and user-friendliness for devices likely to be used by the typical householder.

There is still the issue of assuring software maintenance over the lifecycle of the typical IoT and dedicated-function device. This will include how newer updated firmware should be deployed to existing devices and how often such updates should take place. It will also have to include practices associated with maintaining devices abandoned by their vendors such as when a vendor ceases to exist or changes hands or a device reaches end-of-life.

But at least it is another effort by industry to answer the data-security and user-privacy realities associated with the Internet Of Things.

ZBook x2 (Product Page, Press Release)

My Comments

Intel are releasing the eighth-generation lineup of CPU processors which have been considered a major step when it comes to performance from the “engines” that drive your computer. This is affecting the the Core i family of processors which are used in most desktop and laptop computers issued over the last few years.

There are three classes of the 8th Generation lineup – the Coffee Lake which is pitched at desktops, the Cannon Lake which is pitched at mobile applications and the Kaby Lake Refresh which also is pitched at most of the ultraportables including the 2-in-1s.

This class of CPU has impressed me more with the arrival of ultraportable computers, especially 2-in-1 detachables and convertibles, that could do more than what is normally associated with this class of computer.

It is brought about through an increase in the number of “cores” or processor elements installed in the physical chip die, similar to the number of cylinders in your car’s engine which effectively multiply the power available under that hood. In this case, the improvements that Intel were providing were very similar to what happened when the “V” configuration was implemented for engine-cylinder layouts that allowed more power from a relatively-compact engine, allowing the vehicle builder to offer increasingly-powerful engines for the same vehicle design.

In this case, there was the ability to use low-power processors like 15-watt designs with the increased “cores” but not sacrifice battery runtime or yield too much waste heat. This opened up the capability for an ultraportable or tablet to be able to do more without becoming underpowered while running for a long time on battery power.

For example, HP just released the ZBook x2 detachable tablet computer which has the kind of power that would work with advanced graphics and allied programs. Some could see this as a typical detachable tablet that could be considered not so powerful but this handheld workstation can use these programs thanks to use of the Intel 8th Generation Core i7 Kaby Lake R processor and NVIDIA Quadro discrete graphics. There is even the option to have it specified with 32Gb of RAM.

Then there’s Dell who have refreshed their XPS and Inspiron ultraportables with Intel 8th-generation horsepower with the XPS 13 benefiting from that extra performance, making the whole XPS 13 clamshell Ultrabook lineup show its relevance more.

What is to happen with the ultraportables is that you won’t need to think of them as being unfit for heavy-duty computing tasks while on the road. You may even find that you could do things like watch a season of downloaded TV episodes or play an intense round of Civilization 6 while you are flying one of the new Qantas non-stop long-distance flights to London or Los Angeles without worrying about the battery dying out.

It will be up to the software vendors to make games and other software that take advantage of these high-performance 2-in-1 computers by exploiting the touchscreens and the higher power offered by these machines. How about a Civilization, SimCity, one of the mobile “guilty-secret” games, or more being available through the Microsoft Store for one to install on that 2-in-1?

Smartphones and voice-activated home-assistant platforms help with managing your prescribed medications

Article

‘Alexa, order my meds’ — start-up NowRx pioneers prescription refills through Alexa and Google Home | CNBC

My Comments

There are steps that are taking place to interlink today’s technology with the chore of ordering your prescription medicines from the local pharmacist.

A system that has existed for a few years in Australia and is continuing to run is eRx Express which works with a mobile-platform app and QR codes that are printed on prescriptions. In this setup, a user could send a prescription order to their local pharmacy by scanning that QR code. But they would have to go to that pharmacy to collect and pay for their medicines, unless the pharmacy has established a home-delivery arrangement for the patient.

The main benefit is to allow a person to start things happening for a prescription to be filled from home, work or a shopping-centre’s food court and not have to wait around at the chemist’s while it is being filled. This system is part of an IT solution that is being offered to Australian doctors and pharmacists to improve the prescription-management workflow.

NowRx, a Silicon-Valley startup, have taken this further by providing a Skill for the Amazon Alexa and Google Home so you can use these voice-driven home-assistant platforms to order your prescription medicines. They want to make it feasible for you to request, refill or renew your medications with the last four digits of your prescription number.

Like the rest of Silicon Valley with their approach to traditional business models, they see it as a way to take on the traditional local chemist’s shop by running a robot-driven warehouse and home-delivery service, and at the moment, they have 400 Bay Area doctors as part of their network. NowRx uses Amazon and Google as a facilitation path so that their patients’ medical data isn’t held by the home-assistant platforms; something that is set up to avoid storing that data on systems that aren’t compliant with the US’s standards concerning medical-data privacy.

There are some people who could see these systems as trampling on what the pharmacy is about, including the management of a patient’s medication and the face-to-face interaction with the pharmacy’s customer base. But if these systems are set up as something that augments a local pharmacist’s workflow such as providing an express path for the supply of medication integral to a patient’s continual-therapy requirement, they can be seen as legitimate by most communities. This is more so where pharmacists are able to and encouraged to provide supplementary health-care services like vaccinations or first-aid as well as dispensing medication, a practiced performed in some European countries.

One of the analogies that can be related to with these services is when the financial industry started implementing automatic teller machines. There was the initial fear of these machines were about replacing bank teller staff but they ended up being primarily as an express option or an all-hours option for a customer to withdraw cash. In this case, the eRx and NowRx platforms would serve more as an express path for a patient to get to the medicines they need as part of their long-term therapy requirements.

Press Release

My Comments

Western Digital had broken the record for data stored on a 3.5” hard disk by offering the HGST by WD UltraStar HS14 hard disk.

This 3.5” hard disk is capable of storing 14Tb of data and has been seen as a significant increase in data-density for disk-based mechanical data storage. It implements HelioSeal construction technology which yields a hermetically-sealed enclosure filled with helium that leads to thinner disks which also permit reduced cost, cooling requirements and power consumption.

At the moment, this hard disk is being pitched at heavy-duty enterprise, cloud and data-center computing applications rather than regular desktop or small-NAS applications. In this use case, I see that these ultra-high-capacity hard disks earn their keep would be localised data-processing applications where non-volatile secondary storage is an important part of the equation.

Such situations would include content-distribution networks such as the Netflix application or edge / fog computing applications where data has to be processed and held locally. Here, such applications that are dependent on relatively-small devices that can be installed close to where the data is created or consumed like telephone exchanges, street cabinets, or telecommunications rooms.

I would expect that this level of data-density will impact other hard disks and devices based on these hard disks. For example, applying it to the 2.5” hard-disk form factor could see these hard disks approaching 8Tb or more yielding highly capacious compact storage devices. Or that this same storage capacity is made available for hard drives that suit regular desktop computers and NAS units.

My Comments

The voice-driven home-assistant war between Google and Amazon has heated up further. This time, it is taking place in the form of express online shopping services where you can ask the assistant to order common household items and have them delivered to you. Here, it is more focused on you knowing what you are after and wanting to purchase a particular item of a kind.

Amazon has established this service through the Prime marketplace which requires a paid membership with them. This works with the Amazon Dash “push-to-order” infrastructure which is based around network-connected buttons and appliances with similar functionality available from their control surfaces; along with their Alexa voice-driven home assistant.

But Google answered them by offering the Google Express online storefront which works with third-party retailers that have partnered with Google. There is no paid subscription or membership fee and the goods can be delivered for free subject to the retailer’s free-delivery requirements like minimum order value.

At the moment, Google Express is partnering with Walmart, Toys R Us, Costco, Whole Foods and Target; all who are household names in the USA. But Google has pushed out their Google Home voice-driven home assistant to other countries like most of Western Europe, Canada, Australia and New Zealand with some of these countries not yet supporting Amazon Alexa.

If Google wanted to establish local presence for Google Express with markets that have Google Home established, they would have to work with local household names in the retail scene. This may be about dealing with one or more local full-line supermarket / hypermarket chains who have a strong presence in these other countries as in Tesco or Sainsburys in the UK; Auchan or Carrefour in most of Continental Europe; or Coles or Woolworths in Australia.

Of course, a question that can be easily raised is whether the express online shopping platforms that Amazon and Google are pushing are being seen as an intent to “rub out” the convenience stores, mid-size supermarkets and the like that exist close to people’s homes. A similar question was raised regarding the arrival of automatic teller machines and their impact on smaller bank branches. Here, these machines were seen more as an “express” path or “always-available” path for the common bank transactions while the branches were able to serve people whose banking needs were met better through in a “face-to-face” manner. But in the case of the convenience stores and mid-size supermarkets, these places may suit people who prefer to visit a place and buy many goods or services or do their shopping “face-to-face”.

But operating Google Express as simply an “interface” storefront between their platforms and third-party retailers may allow them to deal with more of these retailers rather than run their own online store. As well, Apple, Microsoft and Samsung need to watch what is going on in this space especially as the idea of express online shopping is something that will be part of the competitive platform that is the voice-driven home assistant.

using the same kind of technology as the Q.Rad heater

The high-performance computing industry places importance on keeping the processors cool and one way this has happened is to use liquids which works in a similar manner to how the engine is kept cool in most vehicles. This is where a loop of liquid coolant is passed between the engine block and the radiator and heater core to shift the waste heat away from the engine and, in the typical passenger car or commercial vehicle, keep the passenger cabin to a comfortable temperature when it’s cold outside.

In the computing context, it is implemented in some of the most advanced and tricked-out gaming rigs through the use of a water loop and cooling blocks attached to each processor chip along with a radiator that disperses this heat. Qarnot and Asperitas are implementing it as a way of heating water for free using the distributed-computing “micro data center” concept that Qarnot is known for with the Q.Rad data-processing room heater.

This is also in conjunction with Qarnot implementing AMD Ryzen CPUs in the next generation of the Q.Rad because these workstation processors implement perform better than the previously-used Intel CPUs yet yield the same heat output. This is important due to the fact that Qarnot’s distributed-processing market is focused on 3D rendering and visual effects for the movie and TV industry or risk-analysis in the financial industry.

Gaming rig

and the same kind of liquid-based cooling technology used in some of these gaming rigs

But the Qarnot / Asperitas approach to harvesting the processor heat for water heating is focused primarily around providing domestic hot water for the building’s occupants or to heat the water in a swimming pool or spa installed in that building. It would be seen as having a similar environmental and running-cost advantage to a solar hot-water installation used for the same purposes. Let’s not forget that a larger number of the “edge-computing” servers that dissipate their heat in to the building’s hot-water infrastructure using this approach can provide the right amount of heated water that a building needs.

It also yields an advantage for Qarnot either during the summer season or in areas that have warmer climates because they can maintain the distributed processing concept in these areas due to their need to heat water for our year-round hot-water needs.
