My Comments

This on-demand broadcast is a DLNA-hosted interview that I heard about what the DLNA home media network is all about with its heterogenous benefits.

One key factor that was mentioned many times was the heterogenous nature of the DLNA ecosystem. Here, they illustrated practices like bringing content up from a network-attached storage unit to Samsung TV or a TV hooked up to a network media adaptor from a different vendor using one of Samsung’s Android tablets.

They even cited the ability to use different software like TwonkyMobile or Samsung’s AllShare on the same Android device to do the same task. Even devices like Sony’s PS3 were mentioned due to the ability to discover content hosted on DLNA servers. Other applications that were even raised include delivering pictures to the printer when you want hard copies of them.

Of course, there was a direct comparison to the Apple AirPlay ecosystem which required the use of iOS devices, the Apple TV (or selected AirPlay-compliant devices) as well as content hosted on computers running iTunes for it to work.

Apple users should know that there is software for their platforms in the form of TwonkyMobile or PlugPlayer for their iOS devices and NullRiver MediaLink or similar applications for their Macintosh computers.

The tablet will be the center of the connected lifestyle — Online Video News

My comments

This article is affirming the idea of using a tablet computer like the Apple iPad or the Acer Iconia Tab in the lounge room as you watch TV. Some people may object to this because of the “too many screens” argument. But of course, you will still look at the big screen for the video content.

Small personal TV

One of the most common TV-related apps for the iPad and tablets of its ilk is as a personal screen for viewing content. This could be in the form of downloading or streaming the content to the tablet device and has been subjected to various legal strangleholds with Hollywood.

But it also has been taken further with broadcast-LAN tuner adaptors which tune in and stream TV content to these tablets once controlled via a special app. As well, the use of DLNA media player software can allow you to view video content held on your home network through these devices.

Remote control for large screen

Another application of interest is for the tablet to work as a remote control for the large-screen TV. Here, this would work with apps delivered by TV and set-top-box manufacturers to the various app stores for the tablet platforms.

It would work hand in glove with programming your PVR, use of interactive-TV applications or even using the interactive functions of a Blu-Ray disc; as well as navigating an increasing array of TV channels.

Of course, I have a doubt about this when it comes to activities where you need instant response. I would like to be sure that you tap MUTE on the tablet and you are sure that the racecaller voice that is part of that commercial isn’t heard the moment you press it for example.

As well some manufacturers may limit this function to their tablets, especially if the tablet is the same brand as the TV in question; usually as a way to reinforce brand loyalty.

Show downloaded content on large screen

In a similar way to the previous “small personal TV” application, a tablet computer can be used to show content on the large television or video projector. This can be through a direct connection from the tablet’s miniHDMI socket or AV-out jack to the TV or by pushing the content to an Apple TV or DLNA network media player.

But wait there’s more:

Internet browsing concurrent with TV viewing

A very common application that I have noticed with smartphones and tablets is to engage in Internet use while watching TV. Examples of this include researching a TV programme on IMDB or a concept that was used in the TV program; using the tablet as a persistent scoreboard during a sports game or updating the Social Web during a TV show. I have expanded on the “persistent scoreboard” application in this site by mentioning an increasing number of “scoreboard apps” that are available for most sports codes and leagues and the role of these apps in enjoying your favourite sports fixtures.

The persistent scoreboard could be an app in itself or simply an always-refreshed Web page; and could remind you of where the players stand in that match you are watching. In some cases, the apps provide access to player / team information as well as on-demand video replays or interactive progress maps. Of course, you could head over to other commentary sources for comments other than what the TV commentators are barking about.

As I have seen, a lot of TV shows are integrating the Social Web very tightly in to their programming fabric. This can be typified with selected Twitter and Facebook comments being read out by the compere or a ticker with Twitter comments crawling across the bottom of the screen. Even news and public-affairs events will have official or unofficial tickers running on Twitter or Facebook as people post up comments on these events using the Social Web.

The tablet computer may work better than the “smart TV” Social-Web apps because the TV usually works with one account at a time and you won’t see the show’s video occupying the screen as you post your comment. One or more tablets (or small computers) can perform this function in an individual manner for individual viewers,

Setup requirements

In most cases, a Wi-Fi connection to the home network and broadband connection is all that is needed if the tablet is just being used at home; and would be necessary for network-media-adaptor use. This could allow you to buy a Wi-Fi-only model if it is to stay primarily at home or not be used with an external wireless-broadband router on the road.

Conclusinon

As I have said, the tablet is now working as a supplementary screen in the TV lounge area rather than just as an ebook reader and email terminal.

There have been debates about whether Facebook, Twitter or LinkedIn should develop official client-side applications for their applications when used on regular computers (desktops and laptops) or tablets like the iPad.

When I talk of a client-side application, I am thinking of an application that is written for and runs on the client device’s operating system and interacts with the Web-based social network service through known application-programming interfaces. This is in contrast to the Web-based interface that requires interaction through the client Web browser.

Of course, other people have developed client-side applications for these social networks either as an improvement for existing software projects or as their own projects themselves. These are usually considered third-party applications by the social-network provider and may not support all functions that are being baked in to the social network as it evolves.

The issue here

It may be easy to think that you don’t have to provide these client-side applications for desktop operating systems (Windows, MacOS and Linux) and tablet computers. This is because these devices can typically allow the user to competently navigate the Web-based user interface for the typical social-network service. It is compared to the smartphone having different user-interface needs that are drawn about by the use of a physically smaller screen on these devices.

Drawcards and Benefits

A major drawcard behind the social-network client application for larger-screen devices would be high integration with the device’s operating system and other applications. The benefits of this would be obvious, such as linking the “friends / followers / connections” databases held by the social-network services to local contacts databases maintained by your personal-information-management software or exhibiting of photos and videos from these services full-screen without the chrome associated with Web browser interaction.

Other benefits would include use of the operating system’s notification abilities to “pop up” messages related to these services such as direct messages or friend requests. Even the chat functionality that is part of services like Facebook would benefit from an “instant-messaging” user experience of the likes of Windows Live Messenger and Skype. This is an always-available presence list and application-created chat windows for each conversation. There is also the benefit of direct access to connected devices like printers or cameras.

Of course, there would be the computer-performance benefit of not needing to maintain a Web-browser session for each social-networking session. This is because the applications can be pared down to what is needed for the operating system; and can also be of benefit to those of us who use battery-operated devices like tablets or notebook computers.

For tablets, the user interface could be highly optimised for touch-based navigation and could make best use of the screen area of these devices. This is more so with this class of device being available in two major sizes – a 7” size for something that can stuff in your coat pocket or the larger 10” size. As well, it could include “right-sizing” the interface for the on-screen keyboard when the user needs to enter information to the service, such as through the log-on experience.

Drawbacks

The drawbacks to this will typically include another client application to develop and maintain for the service, which may cost further money for the service provider. It also includes evolving the application to newer versions of the operating system and incorporating the new features that are available through the operating system’s lifecycle.

As well, there will be the factor that the ad-supported Web interface may become more irrelevant and these applications may them limit access to the cash-cow that these services have to make money – users viewing those ads that are on that interface. This is because most users would be reluctant to load ad-supported software on their desktop computers due to system-performance and privacy issues that have been brought about by highly-intrusive adware.

Conclusion

It may therefore be worth the social networks considering the idea of developing client-side applications for desktop and tablet operating environments. This is in order to provide the user-experience improvements that such applications can provide for this class of usage.

DECT-Telefon mit Android: Archos 35 Smart Home Phone – COMPUTER BILD (Germany – German language)

My Comments

I have previously covered various attempts by landline-telephony carriers and electronics manufacturers to restore faith in the classic telephone service. This is more so as younger people are thinking more of the mobile phone as their main telephone device and ditching the classic landline telephone.

The two main examples of this was a DECT cordless telephone handset which worked on the Android operating system but looked like an early-generation car phone as well as the Telstra T-Hub with a separate screen which linked to the home Wi-Fi network.

Now Archos have taken this further with a DECT cordless telephone that is styled like the typical smartphone. As well, they have run this phone on the Android platform with the ability to download software to the phone through the Wi-Fi network. They even have run TuneIn Radio, which is an Internet-radio client, on this phone so it can offer the same Internet-radio experience as the T-Hub’s Internet-radio client.

Archos have emphasised the DECT cordless-phone setup because most of the Internet-gateway devices that are part of a fully-featured “triple-play” service in Europe, especially the Germanic countries (Germany, Austria and Switzerland), can work as VoIP base stations for these handsets. This allows for centralised management of the handsets and for the assured quality-of-service that DECT offers.

It will be interesting to know who else will try to run with a “smart household phone” system to keep the classic home-based voice telephone service alive and relevant in the mobile world.

Click on or scan this barcode from your Android device to install this program.

Introduction

I am reviewing WiFi Analyzer which is an elementary wireless-network site-survey tool for the Android platform. This program is free-to-download but is ad-supported with ads that can be suppressed for a few weeks at a time through a user option. There is also the ability for users to donate via PayPal to keep the program being developed.

Like all other WiFi site-survey tools, this program relies on the “beacon” information sent out by wireless networks at regular information and a low-traffic wireless network may occasionally show up on the program’s radar whereas a regularly-used network will exist on the program’s radar.

Data views

This program has a few different methods of visualising the wireless-network space that your Android device as listed below.

There is a Channel graph which, like inSSIDer, can show the relative strength of each SSID on the Y axis and channel positioning on the X axis. This can be useful for determining whether a wireless network is being swamped out by other networks or determining where to tune the wireless access point’s operating channel to.

Wi-Fi Analyzer Channel Graph

There is also a time graph which shows relative signal strength of access points over a time period. This can be useful for determining what happens when a certain network comes on line for example.

There is also an access-point list which lists each access point that the Android phone can pick up. Here, you are provided with the ESSID, BSSID, channel number and security type (including WPS capability) of each access point and can have this sorted by ESSID, channel,signal strength or security type (“openness”). This list can be grouped by ESSID and security type so you can identify multi-access-point networks. This view may not be accurate if you have multiple wireless routers in an area set to default SSIDs like “linksys” or “dlink” but working on different WEP keys or WPA passphrases.

Wi-Fi Analyzer Network List by ESSID

There is a Channel-rating bar graph which measures channel useability by the number of stars where the more stars that exist, the better the channel is for your network. You can also “set” an access point to this graph so you can compare channels to the one it is tuned to at the moment. Again, this would come in handy for tuning the access point for best operation.

Lastly, there is a Signal strength meter which allows you to measure the signal strength of an access point. This can be useful for locating rogue or interfering access points or simply to determine the coverage of an access point.

Wi-Fi Analyzer signal strength meter

There is the ability for one to connect to a network if the user installs the “WiFi Connector Library” either through the application or by visiting the Android Market. This can allow the user to “lock-on” to a network while monitoring other wireless access points.

It works well as a basic handheld tool for setting up a new wireless router or access point or keeping a small wireless network operating at its best. For businesses who run public wireless hotspots, this program allows them to assess their hotspot’s performance or find rogue access points (fake hotspots / evil-twins).

Usage tests

I had put the program to some usage tests with different wireless networks including my own and a wireless hotspot, This hotspot was a complementary-use service run by a small independently-run cafe whom I have been helping out with concerning its performance and keeping it “business-safe”. Here, I used the signal-strength meter to check that there was proper signal coverage over the public dining room and terrace area of that cafe. I also used the channel-graph view to determine if there are other access points or ad-hoc wireless networks able to be picked up in the cafe. Both of these functions worked well with assessing the hotspot’s coverage and quality-of-service.

As well, I used it in two shopping strips to assess how it and the Samsung Galaxy S Android handset that I was running it on could handle many wireless networks. It is able to identify each SSID and plot it properly on the graph and could cope with me walking into and out of particular access-point coverage ranges.

Limitations and Points of Improvement

For this application, the program could support “whitelisting” of BSSIDs against an ESSID so that one can easily know if the access point that is using your ESSID is really your network. This would work well with managing public networks like wireless hotspots by identifying rogue access points like the aforementioned “fake hotspots”. It can also work well with managing multiple-access-point wireless networks.

A “Pro” version, which would be sold for at an extra cost and wouldn’t have in-app advertising, could provide various extra functions like SSID whitelist management for use in optimising or managing wireless-network activity in particular sites or GPS support for “plotting” network coverage maps or the ability to keep standard log files for use with desktop software.

It is worth noting that this program is restricted to the frequency bands that the smartphone or tablet can cover and this is typically the 2.4GHz platform. At the moment, there aren’t any Android devices that can cover the 5GHz spectrum using their own hardware.

Conclusion

At last this is a program that answers my need for a cost-effective easy-to-use handheld network-survey tool in a popular smartphone platform. It can therefore be a good companion program to the inSSIDer program that I had previously reviewed on this site.

The Android technology doesn’t stop at handsets or tablets anymore at this year’s CES.

In the car

Parrot are premiering the “Asteroid” which is an Android-powered car radio / multimedia player. It has USB for connectivity to iOS devices, USB flash memory, wireless-broadband modems and GPS pucks at the moment as well as line input for regular audio devices. I am not sure what Bluetooth or hands-free calling abilities it has at the moment but this could change by the time it is released. Of course it has FM radio and, through the 3G connectivity and an Android app, could support Internet radio in the car as well as being a media player and GPS navigation device. It has a power output of 55W x 4 but also has three preamplifier outputs (front, rear, subwoofer) so it can be the head unit for the most tricked-out sound system on the street. Oh yeah, boys!

Similarly, Fujitsu Ten are previewing an satellite-navigation unit which is powered by the Android operating system. The main issue with these Android systems at the moment is that the Google “Android Marketplace” doesn’t support them because they use an interface that is dissimilar to the handset or tablet devices. Here, Parrot or Fujitsu Ten will either have to contract with an Android app store to supply applications to these devices and this app store would have to support the user interfaces provided by automotive Android devices.

In other car-tech news, Ford have developed an AppLink system so that specific iOS apps can be operated from the car’s dashboard. As well, General Motors have developed an IOS link to their OnStar vehicle telematics system but the main problem with these systems is that they necessitate an extra app on the smartphone for each marque. This is compared to Terminal Mode which the European vehicle builders are implementing, which allows one piece of software on the smartphone for many different vehicles and suits the reality that most of us will drive different vehicle marques through our driving life and even have regular access to two or more different vehicles.

As well, GM are intending to implement the PowerMat wireless-charging system in the  American-market vehicles from model-year 2011 onwards. This allows devices with Powermat charging circuitry, whether integrated or as an add-on module to be charged or powered on a special mat wirelessly. I have wondered whether this announcement will then apply to GM nameplates other than Buick, Cadillac, Chevrolet or GMC or other markets.

Networked Home Entertainment

Video Entertainment and the Home Theatre

As far as video-based home entertainment goes, 3D video still rules the roost with every one of the major camera names from Japan with a 3D camera or camcorder in their model lineup. As well, every major TV brand that serves the US market is selling a 3D flatscreen TV in their model lineup. Most of the manufacturers are working on 3D viewing technologies that either don’t need glasses or can work with lightweight glasses. This also includes some manufacturers establishing design partnerships with glasses-frame designers to make attractive 3D-viewing glasses.

But there is a lot more action when it comes to network-enabled TVs and video peripherals This is again driven by the supply of  “over-the-top” Internet video services like Netflix and Hulu Plus. It is also being helped along by manufacturers building up “app platforms” which allow the user to download apps to the TV as if it was like one of the smartphones. It can capture the reality of interactive TV as well as use of common Internet services like Twitter, YouTube and Facebook from the comfort of your couch. As well, programs like Skype are being implemented on these TVs in order to make them become large-screen video-conferencing units for the home or small business.

LG have supplied the ST600 Smart TV kit, which is an add-on kit for selected (or all?) LG TVs to link them to the Internet and the DLNA Home Media Network. As well, one of their pico-projectors that they had on show is equipped with an digital-TV tuner and can stream content from a DLNA Media Server.

Sony now has it that all of their new Blu-Ray players are all DLNA and Gracenote enabled/ They all can quickly start a Blu-Ray movie and have support for the “Media Remote” RF link with Wi-Fi-enabled iOS or Android device running a specific app. These same features are also available to their Blu-Ray home theatre systems.

As well, most of the Sony BRAVIA TV range released this year will be network-enabled with DLNA, Internet TV, Skype large-screen videophone and similar functionality. Some models will have integral 802.11n Wi-Fi functionality while the lower-cost models will require a dongle to connect to the Wi-Fi network. This really shouldn’t worry most users because they could use direct Ethernet or HomePlug AV links to connect the TV to the home network.

The Skype videophone function will work with an optional USB webcam / microphone kit that will be available from Sony.

As well, most of the TVs and home-theatre systems honour the full HDMI 1.4 expectation with Audio Return Channel. This means that the sound from the TV’s integrated sources like the digital TV tuner travel back to the home theatre amplifier using the same HDMI cable used to connect the TV to that amplifier. There is no need to use extra digital cable runs to have properly-decoded surround sound from TV broadcasts received via the TV’s tuner.

As well, Sony has released a network-audio product that makes Apple squirm when it comes to their Airport Express and AirPlay subsystem. This product which comes in the form of the HomeShare speakers connects to a Wi-Fi home network and can play out audio content under the control of a UPnP AV (DLNA) Control Point like Windows 7 or TwonkyMedia Manager. This same control functionality is also available in Sony’s latest Blu-Ray Players as well as the NAS-SV20 and NAS-SV10i iPhone docks.

Samsung have come around with a Blu-Ray player that is the thinnest such player ever. This Wi-Fi-enabled player can be wall-mounted and, in my honest opinion, is cutting in on Bang & Olufsen’s “design AV” territory.

They also are releasing the D6000 TVs  which work with RVU compliant pay-TV gateways. This standard, which is a superset of DLNA for pay TV applications). enables access to the full pay-TV feature suite like pay-per-view or video-on-demand without the TV being connected to the pay-TV operator’s set-top box/ This concept has been proven to works with an RVU server box that links to DirecTV’s satellite pay-TV service.

Iomega have also released a Boxee TV set-top box which is similar to D-Link’s unit. But the similarity stops here because it has integrated NAS functionality with DLNA Media Server. It is capable of working with Ethernet wired or 802.11n Wi-Fi networks and uses a double-side remote with QWERTY keyboard. It is available as an enclosue or with a 1Tb or 2Tb hard disk.

Vizio, a low-cost TV brand in the US similar to Kogan, is to implement Via Plus (Google TV) in their Internet-enabled TVs. They will be providing apps that link to Hulu Plus, Blockbuster On Demand, and other popular “over-the-top” TV services. These sets will also have Skype functionality when used with a USB webcam. Vizio will also be implementing glasses-free 3DTV and are dabbling in 21:9 ultra-widescreen TV

Cisco have been focusing on the interactive TV front but in a different way. They sell  the Scientific Atlanta set-top boxes on contract to cable and satellite providers and are implementing an app platform on their newer boxes. This also means that they are providing a “VideoScape” content-selection experience so that users can find the content they are after or look for related content easily.

JVC have released the first “soundbar” speaker system which implements the HDMI 1.4 Audio Return Channel. Here, this technology comes in to its own with these speakers because the sound from the TV emerges through the easy-to-set-up soundbar unit.

Internet radios

Grace Digital have released three Internet radios that have a similar user interface to the Grundig TrioTouch stereo Internet radio or the Revo IKON stereo Internet radio. Here, these sets use as their primary user interface a colour LCD display with icons laid out in a grid not dissimilar to a smartphone or tablet. The Mondo is designed to be a full-on clock radio for the bedside and has a 3.5” display, Ethernet and line-out connectivity and a remote. The Solo Touch is a tuner that connects to one’s favourite music system and has a large 4/3” touchscreen. It connects to the home network via Ethernet. The Bravado X is a stereo table radio with line in / out and has a 2.7” display. These units can also be controllable via a smartphone app which is available for the iOS only at the moment.

As well, Vizio have jumped on the Android bandwagon by providing a stereo table radio which operates on the Android platform. This one is controlled by a colour LCD touchscreen like the typical smartphone. It would most likely would have an Internet-radio app and also pull in music from a DLNA Media Server device.

The next article in the series will focus on network-infrastructure technologies for the small network and what is being offered here.

Introduction

A trend that we may be seeing with smartphones and similar devices is that they work with various third-party sensor or controlled devices through the use of various apps written by the sensor’s or controlled-device’s vendor. A main driver for this trend has been the “There’s an App for that” mentality that has been established around the Apple iPhone with that smartphone becoming the centrepiece of most people’s lives.

Examples of this include the recently-launched Parrot “ARDrone” remote-control helicopter that uses a dedicated Wi-Fi link to an iOS device running a special app that is its controller; a barbecue thermometer being launched at the Consumer Electronics Show 2011 that uses a Bluetooth link to an iOS device that acts as a remote temperature display. There were even other examples like the Nike running-shoe pedometer that uses a dedicated wireless link to an iPod Nano running an exercise-tracking application.

These applications may be novelty ideas of implementing an iOS or Android smartphone as a SCADA (Supervisory Control and Data Acquisition) device but there will be more applications that will become more real in our lives.

Examples application fields will include:

• Food safety (thermometers that measure temperature for areas where perishable food is stored)
• Personnel health and wellbeing (blood pressure and heart-rate monitors)
• Building automation and security (dashboard apps that work with HVAC, security systems, smart meters and the like; garage door openers that work with a touchscreen smartphone)
• Automotive and marine instrumentation (engine monitoring and diagnostics)

The current situation

The main problem is that whenever an application that works with an outbourd sensor or controlled device is developed, a lot of code is added to the program to work with the sensor or controlled device. This extra “bulk” is written by the app writer usually because the writer is the one who designs the device. The communications between these device and the host smartphone or tablet is typically using USB for wired connections; Bluetooth, dedicated or network-integrated Wi-Fi for wireless connections and the application developer has to work with the link that is appropriate to the device.

If the device designer wants to build a lively application-programming environment around the device, they have to either prepare a software development kit which usually requires the distribution of a runtime module with the application. This can take up memory and can put a strain on the battery life of the device.

What can be done

An improvement to this situation that would improve the lot for device designers and application developers who write SCADA for smartphones and tablets would be to establish a “driver” model for sensor and controlled devices.

Here, the operating system could run a “driver” for the application in a similar vein to how peripherals are managed by desktop operating systems. Here, the operating system can do things like manage the polling cycle for sensors or transmission of events to controlled devices, including responding to sensors that are set to trigger software events for the device class.

This can help with conserving battery power by disconnectiong from a sensor or controlled device if the destination apps aren’t run; or sharing data between two or more apps benefiting from the same sensor data. This could benefit some platforms, most notably Android, where one can write lightweight indicator applications like “widgets”, notification-area icons or active wallpapers which just benefit from sensor data or respond to certain conditions.

The problem is that the smartphone operating systems such as iOS and Android don’t support the same kind of programmatic modularity that desktop computing has permitted due to limitations placed on them by battery-operated handheld device designs with constrained memory and storage size. This issue may have to be examined whenever a subsequent major revision of the smartphone operating system is being worked on; and could include whether a separate “driver store” is maintained at the platform’s “app store” or that drivers are supplied as “apps”. This can then allow the manufacturers to update drivers as necessary, for example to add new functionality.

Conclusion

The idea of controlling or monitoring devices from computers or mobile devices is going to becoming something more mainstream rather than just a novelty and the operating system designers may have to factor this in to their designs.
