My Comments

Soundbars and TV speaker bases are becoming an increasingly-valid path for improving your TV’s sound because they provide the sound through just one box, perhaps along with a subwoofer enclosure. This is because the typical flat-panel TV is becoming more slim but doesn’t have much thought put in to its sound quality and most of us want to hear our shows through something a bit better than that.

As I mentioned in another article on this topic, they will appeal to people who have their TV set up in the traditional manner with it being in the corner of the lounge so as to avoid it competing with the view offered by a feature window or fireplace. They also will appeal to those of us who like our music via a dedicated stereo system with its own speakers, something that is considered to be important thanks to the “back to basics back to vinyl” trend.

In some countries where there is a competitive market for “triple-play” Internet service or subscription-based TV service, the features that a set-top box or PVR offers are seen as a selling point for each of the service providers. As well, most of these telcos or pay-TV providers want to be in a position to upsell customers to better services.

This has led Netgem, a French set-top-box designer to offer to these providers a device which has a soundbar and set-top box in the one housing. It will have the ability to work with a variety of online video and music services and can be controlled by the traditional remote control or a smartphone app. But this box is also being equipped with Amazon Alexa support which allows it to work in a similar vein to the Amazon Echo wireless speaker. The Amazon Alexa agent will also learn media-navigation skills pertaining to this device so you simply can select what you want to watch by voice.

Philips achieved a similar goal by offering a soundbar with an integrated Blu-Ray player,  2-band (FM / Internet) radio and network media player in order to provide a soundbar equivalent to the “home theatre in a box” systems.

The idea behind this box is to allow a telco or pay-TV provider to provide a device that is better than usual to differentiate itself from the others. This is more so where they are focused on selling a “solution” rather than selling a product or service. In most cases, it could be seen simply as an optional device that customers can request rather than as the standard device for a premium package. It is because there will be some customers who will have their own soundbar or home-theatre setup as the way to improve their TV’s sound and simply want a set-top box as the gateway to an IPTV service.

As well, implementing HDMI-ARC, DLNA MediaRenderer, AirPlay / Google Cast playback and similar functionality cam make sure that this device can earn its keep as part of your networked personal A/V setup.

What is showing up is that, especially in Europe’s competitive markets like France, there is a strong interest amongst whoever is offering triple-play broadband service to provide something that offers that bit extra.

The home-network gateway device to become advanced

D-Link Covr router and wireless extender package press image courtesy of D-Link

Expect a lot more out of the router that comes with your Internet service when Technicolor gets its way

The device that represents the network-Internet “edge” for your home network i.e. the router won’t just be serving that function in a standalone way anymore. Here, it will work in tandem with other Internet-side and network-side computing devices to become a highly-sophisticated “hub” for your home network.

One of these drivers is to provide a simplified customer-support process, especially for those of us who use carrier-provided equipment at the edge. Here, the support and provisioning process can be fulfilled by the router supplying information to your carrier or ISP regarding your Internet service’s and home network’s performance.without wasting time requiring the customer to supply this information during a support call. This may be considered controversial but has value regarding the support and troubleshooting process which can perplex those of us who aren’t competent with technology such as a lot of older people.

It also encompasses the fact that distributed Wi-Fi will be the “new norm” for the home network, whether through multiple access points connected to a wired or dedicated-wireless backbone, the use of one or more wireless range extenders or a mesh-driven distributed wireless network. Here, it may be about simplifying the process of commissioning the “satellite” wireless devices and making sure that they are performing as expected to assure maximum Wi-Fi coverage across your premises.

The other factor is for a call to provide for always-maintained software in these devices thanks to issues being raised regarding the security of our home networks and the Internet. It was underscored through the recent distributed denial-of-service attacks against various Internet services and blogs using the Mirai bot network that was running compromised software on routers, network cameras and the like which hosted poorly-maintained software to facilitate these attacks.

Let’s not forget that the home-network gateway device will be expected to do more in conjunction with cloud services. Here, they want to provide this kind of service in the same context as the “app-store” commonly associated with mobile computing platforms but increasingly associated with regular computing platforms, and an increasing number of dedicated-purpose devices like printers. It is where a customer can add on extra functionality to their home-network router after they have bought and installed that device rather than buying and installing a new device to achieve this goal.

I was learning about this thanks to a news release offered to me by Diego Gastaldi from Technicolor Connected home regarding this topic. Technicolor came in on this game thanks to buying in to Thomson who supplies a lot of the customer-premises equipment provisioned by telcos and ISPs for their broadband Internet service, especially the triple-play services. This company had presented at Mobile World Congress some of their new concepts for the home-network gateway devices that will be pitched to the likes of Telstra or Bouygues Télécom for their services along with how they can add that extra value.

This is in conjunction with Technicolor announcing their solutions for managed distributed Wi-Fi setups along with devices supporting wireline broadband and mobile wireless broadband on the Internet (WAN) side. The latter trend existed mainly with small-business equipment but its appeal for the home network is being underscored with the “quick-to-provide” goal for an interim wireless service before a wireline service is rolled out, a “fatter pipe” for broadband service by aggregating wireline and mobile broadband services; and always-available broadband for business, e-health / ageing-at-home and the smart home’s security.

The typical applications that will be called out would be to provide business-style “unified threat management” for the home network as a network security measure. Or they could be about joining a “community wireless” platform like Fon where they can share Wi-Fi bandwidth with guests or customers.

But they are also highlighting applications like monitoring elderly loved ones at home to be sure they are OK. Earlier on in 2010, I had a conversation with a representative from Ekahau regarding their Wi-Fi-based Real Time Location System in a residential or small-business environment. This was more so with their T301BD Wi-Fi Pager Tag, pitched primarily as a name tag with duress-alert abilities for healthcare and similar enterprise-level applications, being used as part of an “ageing at home” or similar home-based care scenario. Then I had noticed initial doubt about this kind of application in the home but such setups could be made real with distributed Wi-Fi and them being offered on a cloud-driven “as-a-service” model.

By using a multiple-computer “cloud” approach, there isn’t a requirement to overload a router device with extra processing circuitry which would require a large device to be designed. Typically this would be fulfilled by the use of one or more data centers connected to the Internet like the Amazon Web Services approach Technicolor are using. But, as the compact network-attached-storage maintains its appeal as an on-premises network storage hub with most of these devices offering “remote access” or “personal cloud” functionality, this kind of “cloud” approach could encompass these devices along with other “function-specific” hubs like smart meters or security systems.

But what is happening is that there will be more expectations out of the router device that sits between the home network and the Internet with it being a “gateway” to more online services.

Google provides a tool to forums and the like to combat trolls

Article

ThinkBroadband forum

ThinkBroadband Forum – an example of a forum where content moderation can be simplified using Google Perspective

Google’s new innovative technology aims to combat online trolls | Android Authority

My Comments

Previously, I wrote an article regarding the Internet troll problem faced by people who have an Internet presence on a social network, forum, chat-room or similar environment. It is where they face toxic comments and online harassment on these boards from miscreants who use their presence there to make trouble.

A small business’s Facebook page – Google Perspective can make the management of these pages simple when it comes to visitor comments left on these pages

This is made worse for those of us who operate a corporate Internet presence on these environments for their business or other organisation or moderate a forum, blog or similar online presence. In some cases, it has caused some of us not to run these forums at all or turn off commenting ability for the blogs or other online content we publish.

But Google has come to the fore by developing software that allows moderators and users to gain better control over toxic Internet comments. This is based on a human-driven review cycle for comments such as end-users reporting or moderators disallowing comments discovered to be toxic. The Google Perspective software described here learns from the identified troublesome comments in order to determine what happens with new comments.

It is being offered as a set of application-programming-interface “hooks” that can be integrated with content-management systems, social networks and the like. But who knows how long it would take for the APIs that support this functionality to be offered simply as “wrapper” plugins for the popular extensible content-management or forum-management platforms. Similarly, an “outboard” comment-host like Livefyre or Disqus could benefit through offering the Google Perspective technology as a feature to help moderators with manage incoming contents.

They promoted the ability for a moderator to use Perspective to conditionally manage comments that are to be held for moderation or to red-flag potential “flame-wars” and miscreants. But they also put forward the idea for users to filter or sort comments by toxicity which can be of use for most of us who simply don’t want to waste time reading that junk.

What I see of this is that the Google Perspective comment-management software is something that could make it easy for those of us involved in the Internet conversation to make it easy to dodge the troublemakers.

What will 802.11ax Wi-Fi wireless networking be about?

ASUS RT-AC5300 router press picture courtesy of ASUS

802.11ax will be the next Wi-Fi standard that will grace our routers, but this will require newer hardware

There is the impending plan to define the IEEE 802.11ax Wi-Fi wireless local-area-network standard which is intended to supplant the 802.11ac standard used for general-purpose Wi-Fi networks. Qualcomm are even offering an initial lot of silicon for this standard in order to have something that can be proven.

But what is it about?

One of the man benefits is wider bandwidth which allows for five times more bandwidth than what 802.11ac offers. But there is also the idea that we will see Gigabit throughput levels being offered for real rather than as headline speeds which are based on a “link-level” speed without any error correction.

This is brought about with increased MIMO multiple-antenna / multiple-front-end abilities such as MIMO-OFDM, which is expected to improve Wi-Fi’s robustness. The MU-MIMO functionality which effectively provides optimum bandwidth to each client device will work for downstream and upstream data.

Yarra's Edge apartment blocks

802.11ax Wi-Fi wireless will benefit apartments, hotels and trade shows where many Wi-Fi networks do co-exist

802.11ax Wi-Fi implements spatial frequency reuse to improve network reliability in high-density setups. Current Wi-Fi setups don’t really perform reliably when they are faced with a high-density setup like a trade show with connections dropping off too easily. But there is the ability to reuse frequencies and co-exist to assure improved reliability in these situations. It also answers a reality with Wi-Fi and high-density urban living where you will come across with each small apartment, office or shop in a large building ends up being equipped with its own Wi-Fi network, something that will be more so with next-generation broadband service being delivered to the premises.

Something more real that will underscore the robustness that 802.11ax provides

To the same extent, this level of robustness in dense Wi-Fi environments also applies to situations where Wi-Fi networks that have multiple access points including range extenders are being implemented by most people to assure optimum network coverage for their portable devices. It is a practice underscored by the reality that a Wi-Fi router is typically installed at one end of the premises because it has to be colocated with the connection that facilitates a wired broadband connection like a telephone or cable-TV socket.

Let’s not forget that the Wi-Fi WMM and WMM Power Save standards will be improved under this specification to assure continual throughput for streamed multimedia content; along with power-efficiency for battery operated devices. These standards will be improved to cater towards an increased volume of data.

The 802.11ax Wi-Fi standard is not intended to be set in stone before 2019 although there will be equipment being released to earlier drafts through the next few years. This is a practice that has happened with 802.11n and 802.11ac Wi-Fi, with the Wi-Fi Alliance even calling the standards before IEEE had the chance to call them. But it could be seen more or less as the wireless local network standard to complement next-generation fibre-optic or 5G wireless broadband Internet services that offer Gigabit or more bandwidth.

What’s inside your computer (INFOGRAPHIC)

Some of you who have a traditional “three-piece” desktop computer system where there is a separate box where all the activity takes place, may refer to this box of your computer setup as the “hard disk” even though it is known as a “system unit”. This is because the hard disk, amongst the other key computing subsystems like the CPU processor and the RAM exists in that box.

This infographic shows what the key parts of your computer are and is based on one of the newer small-form-factor designs that are common in the office and home.

Fact-checking now part of the online media-aggregation function

Article – From the horse’s mouth

Google

Expanding Fact Checking at Google (Blog Post)

My Comments

ABC FactCheck – the ABC’s fact-checking resource that is part of their newsroom

Previously, we got our news through newspapers, magazines and radio / TV broadcasters who had invested significant amounts of money or time in journalism efforts. Now the Internet has reduced the friction associated with publishing content – you could set up an easily-viewable Website for very little time and cost and pump it with whatever written, pictorial, audio or video content you can.

Google News – one of the way we are reading our news nowadays

This has allowed for an increase in the amount of news content that is of questionable accuracy and value to be easily made available to people. It is exaggerated by online services such as search and aggregation services of the Google or Buzzfeed ilk and social media of the Facebook ilk being a major “go-to” point, if not the “go-to” point for our news-reading. In some cases, it is thanks to these services using “virtual newspaper” views and “trending-topic” lists to make it easy for one to see what has hit the news.

As well, with traditional media reducing their newsroom budgets which leads to reduction in the number of journalists in a newsroom, it gets to the point where content from online news-aggregation services ends up in the newspapers or traditional media’s online presence.

The fact that news of questionable accuracy or value is creeping in to our conversation space with some saying that it has affected elections and referenda is bringing forward new concepts like “post-truth”, “alternative facts” and “fake news” with these terms part of the lexicon. What is being done about it to allow people to be sure they are getting proper information?

Lately, a few news publishers and broadcasters have instigated “fact-checking” organisations or departments where they verify the authenticity of claims and facts that are coming in to their newsrooms. This has led to stories acquiring “Fact-check” or “Truth-meter” gauges along with copy regarding the veracity of these claims. In some cases, these are also appearing on dedicated Web pages that the news publisher runs.

In a lot of cases, such as Australia’s ABC, these “fact-checking” departments work in concert with another standalone organisation like a university, a government’s election-oversight department or a public-policy organisation. This partnership effectively “sharpens the fact-checking department’s knives” so they can do their job better.

But the question that is facing us is how are we sure that the news item we are about to click on in Google or share in Facebook is kosher or not. Google have taken this further by integrating the results from fact-check organisations in articles listed in the Google News Website or Google News & Weather iOS / Android mobile news apps and calling these “fact-check” results out with a tag. The same feature is also being used on the News search tab when you search for a particular topic. Initially this feature was rolled out in to the US and UK markets but is slowly being rolled out in to other markets like France, Germany, Brazil and Mexico.

Google is also underpinning various fact-check efforts through helping publishers build up their efforts or instigating event-specific efforts like the CrossCheck effort involving 20 French newsrooms thanks to the French presidential election. It is in addition to supporting the First Draft Coalition who helps with assuring the integrity of the news being put up on the Internet. It also includes the use of the Digital Initiative Fund to help newsrooms and others instigate or improve their fact-checking operations.

A question that will also be raised is how to identify the political bias of a particular media outlet and convey that in a search engine. This is something that has been undertaken by the Media Bias / Fact Check Website which is an independently-run source that assesses media coverage of US issues and how biased the media outlet is.

But a situation that needs to appear is the ability for fact-check organisations who implement those “accuracy gauges” to share these metrics as machine-useable metadata that can be interpreted through the rich search interfaces that Google and their ilk provide. Similarly, the provision of this metadata and its interpretation by other search engines or social-media sites can provide a similar advantage. But it would require the use of “news categorisation” metadata relating to news events, locations and the actors who are part of them to make this more feasible.

Similarly, a social network like Facebook could use the fact-checking resources out there to identify where fake news is being spread so that users can be certain if that link they intend to share is questionable or not.

To the same extent, engaging government election-oversight departments like the Australian Electoral Commission, the Federal Election Commission in the USA and the Electoral Commission in the UK in the fact-checking fabric can help with assuring that there are proper and fair elections.  This is more so as these departments perform a strong role in overseeing the campaigns that take place in the lead up to an election and they could use the fact-checking organisations to identify where campaigns are being run with questionable information or in an improper manner.

As part of our research in to a news topic, we could be seeing the fact-checking resources playing an important role in sorting the facts from the spin and conspiracy nonsense.

Video explaining the Bromium micro-virtualisation approach (Click / Tap to play)

My Comments

A very common attack gateway that has been identified for endpoint computing devices, especially regular desktop or laptop computers, is the Web browser. It is because the browser is essentially the “viewport” to the Internet for most reading-based tasks.

But most recent browser versions have implemented software-based “hardening” against the various Internet-based attacks. This is in conjunction with the main desktop operating systems being “hardened” through each and every update and patch automatically applied. These updates facilitate practices like “sandboxing” where software of questionable provenance is effectively corralled in a logical quarantine area with minimal privileges so it doesn’t affect the rest of the system.

HP and Bromium have developed a “virtual hardware” approach where a browsing session can take place in a separate “logical computer”, a concept being driven by the multi-core CPUs that are the hub of today’s computer systems. This can provide improved security by using the hardware approach that is effectively with its own operating system and has the data destroyed at the end of a session. Here, it restricts the effect of malware like ransomware picked up during a “drive-by” download because the software can only run within that separate “logical computer”.

At the moment, this feature is being initially rolled out to the Elitebook x360 G2 convertible business laptop but will trickle out across the next generation of “Elite” premium manageable business computers to be launched in the second half of the year. It will work only with Microsoft’s Internet Explorer and Google’s open-source Chromium browser at the moment. What I would like to see happen is that this feature is able to be “trickled-down” to HP’s consumer, education and small-business product ranges but in a more “self-service” manner because households, small businesses and volunteer-driven community organisations could equally benefit from this feature.

Set Windows not to interrupt your presentation or movie

Article

Presentation shown on retractable screen

You don’t really want Windows to throw pop-up notifications during that important business presentation

How to disable notifications while presenting on Windows 10 | Windows Central

My Comments and how to go about this further

Most of us encounter times in our work and personal computing lives where we don’t really like Windows to “pop up” too many notifications while we are concentrating. Situations where this is more so include running a presentation, watching video material, engaging in a videocall or playing games where we really crave the minimum of distractions.

Screenshot of Acorn TV website

.. nor while watching that bit of video-on-demand content on your computer

There are multiple approaches to reducing distractions caused by Windows when it pops up those notifications. These depend on the screen setup you are running with.

One screen

Quiet Hours button on Windows 10

Quiet Hours button in Action Center on Windows 10

Most of you who are using that laptop or convertible 2-in-1 will be using this machine’s screen to view your long-form video or show that presentation to two or three people at the “second-office” café. Or you are using a traditional desktop computer like that “gaming rig” and don’t want Windows to distract you from that game you are playing.

Quiet Hours option - a right click away - Windows 10

Right click on the bubble to pop up this menu

Here, you can enable the “Quiet Hours” function to prevent Windows 8 or 10 from popping up notifications when you don’t want them. This can be enabled using a “button” in the Windows 10 Action Center or by right-clicking on the Windows 10 Action Center bubble at the right-hand corner of the screen then selecting “Turn on Quiet Hours”. This will mute all notifications coming in so you aren’t disturbed.

When you have finished, you then disable “Quiet Hours” by repeating the above process. If you right-click on the Action Center bubble, the option that will show up will be “Turn Off Quiet Hours”.

Two Screens – Duplicated display

Windows 10 - Hide Notifications When Duplicating Screen

Use this option to hide notifications when you have two screens replicating each other

Some of you who have a laptop may connect your computer to the projector or large-screen TV and set it up to “duplicate” the display. This is often seen as a simplified approach to putting things up on the large screen especially if both displays have the same resolution and aspect ratio.

As well, this scenario may please those of us who are using Windows Media Player, Windows Photo Viewer, the Windows Store apps or similar software that doesn’t address displays separately, or are simply working with the Web.

Windows 10 has a dedicated setup for this scenario where if you are duplicating the display, you don’t see any of the notifications appearing on both screens. This is a separately-selectable option in the Notifications And Actions settings screen as “Hide Notifications When I’m Duplicatiing My Screen”.

Two Screens – Extended display

Extended Display setup for a secondary display as a dedicated screen - Windows 7

Extended Display setup – for a secondary display as a dedicated screen – Windows 7

There are those of you who have your computer connected to an external display in the “extend” mode. This may be because you are using presentation software that can separately address the external displays or are using the extended multiple-screen desktop.

In this scenario, you would be having your notifications appear on your setup’s primary screen such as your laptop screen. This is although, in a presentation setup, you would be having the presentation appear on the large screen.

But you may want to be sure that you are not disturbed during the presentation or video content. Here, you can follow the instructions for enabling “Quiet Hours” as described in the “One Screen” context.

Managing your system’s sound

On the other hand, you may not mind the visual notifications on your screen such as when you are watching a video or engaging in a videocall. This may be because you want to make sure you don’t miss that message for example.

But you may want to play things a bit more discreetly and not have chimes or bells associated with incoming messages or error notifications disturb you. This is more so when you have the sound coming through a sound system or a large-screen TV’s speakers, and these sounds at the default volume level can be increasingly annoying to hear.

This situation shows up very strong where the software you are using doesn’t allow you to determine which sound-playback device it should play through and you have to use the Windows “default sound device” typically shared by the system for its notification purposes. This situation applies mainly with Web-based situations, UWP / Modern / Metro apps that you get from the Windows Store or some online-service clients like Spotify.

There is the ability to turn off audible chimes for apps that put up notifications but let them put up the visual notifications. Here, you may have to use the Notifications settings screen and work through each app and turn off the “Play a sound when a notification arrives” option on each app. Then you would have to do this rigmarole again when you want the audio prompts back.

Volume Mixer in Windows 10, similar to other Windows versions

Volume Mixer in Windows – System Sounds are the notification chimes and dings

Here, you can work around this problem by using the Windows Volume Mixer to reduce the System Sounds volume output so that those beeps and chimes don’t come through very loud. You can even slide that volume right down so that those sounds can’t come through at all. If you are using Windows Store apps like some of the Windows 10 clients for the various online video services, you could use “Ear Trumpet” (Free download from Windows Store) which is an advanced volume mixer that works with these apps as well as Desktop (classic) apps as well as integrating with the Windows 10 look and feel.

Ear Trumpet volume mixer app for Windows 10 - manages Windows Store apps

What Microsoft could do

Microsoft could support a “notifications profiles” setup in Windows where you can turn off the notifications abilities for particular apps and save these setups as one or more profiles. Here, it could be useful to allow users to create situation-specific profiles such as one to have when watching video content, running a business presentation or going to bed.

It could be implemented also with notifications being assigned “priority” levels so as to allow users not to have “hints-and-tips” or similar unimportant notifications come through at “do-not-disturb” times yet have important notifications come through. For email, messaging and similar software, user could assign priority levels for their contacts so that they don’t miss messages from the contacts that matter like the boss.

The sound-management software in Windows could allow you to create situation-specific sound-level settings like what happened with the Symbian-based Nokia phones. This was where you could create sound-level scenarios for particular situations by varying different sound outputs like ringtone, notification tones and multimedia sounds (music or video playback). This also appeals to other ideals like being able to relegate sound classes like system notifications to particular output devices independent of other sound classes like multimedia and communications.

Conclusion

Once you know how to manage the notifications that pop up in Windows 10’s Notification bar, you can be able to make sure you aren’t distracted by this noise when you want to run that important presentation or watch that favourite Netflix. Similarly, adjusting the sound output of your apps, especially those that are only about notifying, can allow you to achieve that quiet environment while you enjoy music, watch videos or give presentations.

Wi-Fi TimeSync–to make multichannel Wi-Fi wireless audio real

Article

Wi-Fi might fix wireless speakers this year | The Verge

Wi-Fi for audiophiles: Alliance preps TimeSync certification program | The Register

From the horse’s mouth

Wi-Fi Alliance – TimeSync

Product Page

Whitepaper (PDF)

My Comments

Denon HEOS wireless speakers

Speakers like the Denon HEOS family will benefit from WiFi TimeSync so that they can be used with different manufacturers’ systems

The Wi-Fi Alliance have worked towards a standard for keeping time-sensitive data synchronous on a Wi-Fi network segment. This has become a very difficult situation with networks that rely on packet-based data-transfer technology because you are never sure whether data packets are leaving or arriving at the same time.

The key application case being put forward for Wi-Fi TimeSync is to use Wi-Fi technology to provide multiple-channel audio and video with an open-frame wireless approach for home-entertainment setups.

One implementations seen in this context would be a household starting with the TV’s internal speakers for video sound but moving towards a sound bar and / or external speakers plus a subwoofer located up the front beside the screen. Then they move towards a fully-fledged home theatre setup with rear speakers, using speaker systems from manufacturers they prefer at prices they prefer.

Another implementation would be a single-piece multiroom speaker or single-piece music system. The user then adds one or two extra speakers as their budget allows so they benefit from improved stereo separation. This also comes in to play for a multiple-speaker setup for environments where they want to “spread the sound” such as during a party.

But there are other use cases. One would be to use Wi-Fi in the context of connecting wireless microphones, instrument connections (guitars and electric basses) and wireless monitor setups for recording, broadcast and PA applications. Similarly, video field production would benefit in supporting a wireless link from one or more cameras and audio devices to the one video-production desk or video recording transport; or SMPTE time-synchronisation data can be wirelessly sent amongst multiple AV devices which have their own recording transports like camcorders or audio recorders.

Another use case being put up is showing the same video across multiple displays with a wireless link between the source and the displays. This could benefit automotive, coach and airline applications where the same video content held on a mobile device may be shown on seatback or dropdown screens to the passengers. Similarly, it could be about the use of temporarily-installed displays showing content from one main video system but allowing for “quick setup quick teardown” installation.

They also see this same technology for control and instrumentation applications such as patient monitoring in healthcare applications, industrial automation on the factory floor and, most likely, smart buildings and smart cities. For the smart home, it could be about using multiple temperature sensors to measure indoor room temperature so as to control the HVAC system efficiently.

In these applications, there is a goal to be manufacturer-independent, something that will break a curse associated with current Wi-Fi-based multiroom-audio applications. This is where the multiroom or multichannel functionality will only work with equipment supplied by the vendor or equipped with silicon from the same chipset family.

The Wi-Fi TimeSync standard will be based on the 802.11 Time Measurement standard and will support millisecond-level synchronisation. It will be independent of the baseband (physical-layer) Wi-Fi technology so as to support Wi-Fi segments implementing 802.11n or the newer 802.11ac standards.

A question worth raising is whether access points and routers need to support the Wi-Fi TimeSync standard themselves or if this can be facilitated on existing home or business-grade equipment. Another question that will also be raised is whether the same level of synchronisation can be achieved across a Wi-Fi segment involving multiple access points whatever the backbone. This can also include the common wireless-range-extender scenario that works from an extant wireless-network segment and creates its own wireless-network segment.

Here, it may also be about standards bodies representing the Cat5 Ethernet, HomePlug powerline, MoCA TV-coax and similar wired-network technologies considering higher-level support for packet synchronisation on the media types.

The initial call is that chipset vendors will offer the necessary silicon by end of 2017 for manufacturers to integrate in to their device designs. Then it will take some time for these designs to materialise as equipment like Wi-Fi-based wireless speakers or amplifiers.

What this could lead to an open platform for AV applications which can lead to a breeding ground for innovation and a reduced price point for these devices. Other areas will benefit from using a Wi-Fi wireless network for synchronising real-time data accurately.

Google demonstrates their Google Home concept during Super Bowl 2017

Part of the experience of watching American Football’s annual ultimate playoff that occurs every February is to see the ads that are run during the commercial breaks. This is because, a company has to stump up at least US$5 million per “spot” to get an ad in front of the USA’s many eyeballs who will be watching the Super Bowl. Here, it is also the time that advertisers pull out the stops to show the most impressive and memorable commercials that could end up being run when they want to extend the campaign further.

Google used this year’s Super Bowl to demonstrate the concept of their Google Home voice-activated home assistant platform competing with Amazon Alexa. But is shows what these voice-operated home assistants are all about. Most of the functionality you will see in this ad will require you to install smart-home devices that control your existing lighting or heating.

Have a look at this if you missed it during this year’s “ad parade”.
