Mehr VDSL im Raum Bopfingen – VDSL.de (Germany – German language)

My comments

Just lately, the German VDSL2 next-generation broadband Internet network could be increasing its footprint in parts of Bopfingen, a small city in Baden-Württemberg. The intended scope is to cover the communities of Pfaumloch, Goldburghausen and Utzmemmingen

This is intended to be part of a natural-gas rollout project that is servicing the neighbourhood and this project would provide the opportunity to lay down a fibre-optic backbone to service this same area with VDSL2 next-generation Internet service.

The Bundesregierung (German federal government) were intending to offer to underpin this project at a cost of 450k Euro.

There is some resentment about the VDSL deployment in Goldburghaussen because of the perceived extra expense that the fibre-optic backbone would cause. It is more so for a small VDSL2 deployment which covers fewer “doors” than the other deployments in this region because the economies of scale don’t exist in these locations. This is although Goldburghaussen could increase its VDSL2 service demand due to business wanting to set up where there is the “full-on” next-generation Internet.

There is public money going towards this project, especially from the Bundesregierung as previously detailed. But the main feature that I liked of this project is that it is intended to be part of an already-funded infrastructure-rollout project i.e. the gas rollout where similar work is being done, thus avoiding the need to put up more of the public money just to perform new works for this project.

It should still be subject to competitive access requirements so that there is the ability to deliver competitively-priced service.

Therefore I would support the concurrent deployment if next-generation Internet service with a major customer-facing infrastructure project like a natural-gas rollout or power-cable undergrounding project.

Another step towards easily-configurable IP telephony systems has been taken with the UPnP Forum just releasing the UPnP Telephony Device Control Protocol this week. Here, this provides the management of telephone-related devices that are connected across a small network in a heterogenous manner. This involves the ability for the devices to make or take phone calls, be notified of incoming calls, send and receive text and multimedia messages as well as updating local user-presence status.

It is also intended to be service agnostic so as to cater for phone services based on IP-Telephony (VoIP), cellular wireless or classic landline (ISDN or Plain Old Telephony Service) technology; as well as being device form-factor agnostic.

As with the whole of the UPnP ecosystem, this DCP provides increased room for innovation due to a logical “building-block” approach in designing these systems.

Logical Devices

Telephony Client

A UPnP Telephony Client is a device that is used by the end-user to interact with the caller at the other end of the line. A multi-handset phone system would have these devices referred to as an “extension”. This could be a device like a VoIP handset, a “softphone” program run on a computer, a TV or set-top box with IP-based video speakerphone function or a “legacy-handset-bridge” like an analogue telephone adaptor or DECT base station.

The UPnP Telephony system allows different clients to be media-specific, thus allowing for situations like an electronic picture frame that has a Webcam to become a videophone adaptor with the voice part of a videocall placed using this device being hosted through a regular VoIP handset.

Telephony Server

A UPnP Telephony Server device represents anything that can provide a telephone service to the local IP-based network. This can be in the form of a 3G mobile phone connected to the home network via WiFi, a regular telephone that has integrated PSTN/ISDN – IP bridge functionality, but would typically be in the form of a device that works as an “IP-PBX” with VoIP lines and servicing VoIP handsets.

A physical device can have multiple logical “Telephony Server” devices, with one for each “service” that calls come in on. It doesn’t matter whether the calls come in via VoIP or a classic telephony service like a 3G mobile service or the “Plain Old Telephone Service”.  This can cater for the VoIP-enabled router or “IP-PBX” that can handle a few VoIP services as well as a “Plain Old Telephone Service” line; or a mobile phone or “MiFi” router that "front-ends” its 3G/GSM telephony service to the network.

Telephony Control Point

This is effectively the “control surface” for a UPnP Telephony system and can be integrated with a Telephony Client or Telephony Server or be its own device. Typically this would be the buttons and display on a phone but could be a device with its own display or a “widget application” on a computer showing up the incoming call details or incoming text / multimedia messages.

Functionality provided

This device class manages the creation, management and conclusion of a voice or video call between UPnP-compliant telephony “hub” devices and endpoint devices.

The technology allows for a call to be set up using multiple devices on the local side. A good example of this would be to instigate a videocall with the video display appearing on a videophone-enabled TV with integrated Webcam and the conversation sound coming through the cordless handset. Of course, it will do the usual call-management features like call transfer are able to be performed across a UPnP Telephony-based phone setup.

As well, there is support for a common address book that is based on vCard standards as well as the management of answering-machine / voice-mail setups in these systems. Of course, a UPnP-based IP telephone system can support sending and receiving of text or multimedia messages. This would mean that, for example, incoming messages could appear on devices like networked TVs or a Wi-Fi-based cordless IP phone could send messages through VoIP SMS services or “landline-SMS” services provided on PSTN or ISDN services.

Issues that need to be looked at

Establishment of IP-telephony services

An issue that needs to be looked at is the setup and management of IP-based telephony services. Here, this may include the addition of a new service or the establishment and modification of outbound and inbound call-management profiles associated with multiple phone services.

This may involve the use of predefined call classes like “local” or “international” with the ability to determine which service is used for a particular class. Similarly, there could be the use of “default” outbound dialling plans such as “VoIP for all calls except emergency or service calls”. As far as the small-business owner is concerned, this issue may encompass the creation of IP-based “tie lines” between business locations or the creation of “virtual extensions” which are phone numbers dialled as if one is calling an extension within a business phone setup.

The solution that can be used to answer the problem regarding establishment of such services could be in the form of a standard “service manifest” file. This could be an XML file that is prepared by the ITSP (Internet Telephony Service Provider) with all of the parameters associated with an IP telephony service including SIP parameters and default call-management plans for that service. The service’s customer would upload the file to their VoIP gateway through a client-side application or the gateway’s Web interface and simply enable the service.

Inter-extension calling

In the same case, another issue that may need to be looked at is the ability for a UPnP-based telephony system to support the placing of calls between Telephony Client devices, as required of a business phone setup.

This question could be answered through the use of a virtual Telephony Server in a gateway device that represents and handles the internal calls. This could have the internal phone book which is simply a user-friendly list of Telephony Client devices on the system as well as handling that traffic.

Conclusion

Now that the UPnP Telephony DCP has been determined as a standard, it now requires industry to set about the task of implementing it in as many IP-Telephony devices and software programs as possible.

This could be made feasible through this standard being part of one or more logo-compliance programs like how the UPnP AV DCPs have become mandatory for devices that are DLNA-compliant or the UPnP Internet Gateway Device standard has become mandatory for various standards encompassing Internet modems and routers.

It can also open up opportunities of innovation for any device that offers some sort of telephony function while facing a small IP network; or any computer program that works as a bridge to a telephony service like Skype or as a telephony endpoint like a “softphone”.

Wi-Fi body wants hotspots to override 3G • reghardware

From the horse’s mouth

Wi-Fi CERTIFIED™ Hotspot Program to Ease Subscriber Connectivity in Service Provider Wi-Fi® Hotspots  – Press Release

Wi-Fi Alliance Webpage

My comments

One main thrust behind the Wi-Fi Alliance’s new initiative concerning authentication, authorisation and accounting on public hotspots was to permit a wireless-broadband carrier to use Wi-Fi hotspots as a complimentary cellular technology. This is to avoid the need to buy cellular-telephony spectrum in order to increase service capacity and is increasingly necessary as the available radio spectrum becomes increasingly scarce.

Here, a cellular carrier could run their own Wi-Fi hotspot networks like what Telstra is doing or they could form a partnership with a wireless Internet service provider like “The Cloud” in the UK as a way of providing this service. They could then allow for a customer to seamlessly hand over from a 3G network to a Wi-Fi network that supports these credentials.

The way this is going to operate is to use a SIM card in a smartphone to store credentials for Wi-Fi networks. This card is typically controlled by the cellular carrier and may be only used for login credentials that continue the carrier’s partnerships.

A limitation I find with this is that the carrier could implement software locks so that the customer can’t use public networks other than those provided for by the carrier or their partnership. As well, there are other issues that haven’t been looked at properly with this goal for improved authorisation, authentication and accounting on these networks as I list below.

Venue-controlled hotspots

It can also make life difficult for customers who use hotspots provided by venue owners like hotels or cafes. Here, the login experience is typically managed by the hotspot owner and this may require information like a session ID in the case of a hotspot at a bar or cafe, or a room number for a hotel. These may apply for hotspot service where you pay the premises owner for that service or the service is part of the business’s main operation. In some free hotspots, you may have to click on a form to assent to terms and conditions of the service before you continue using the service.

As well, a user could use a hotspot run by an independent wireless hotspot operator and buy their access themselves through a Web-based user interface before using the service.

What I would like to see is support for these kind of hotspots because the user interface that is provided by most of them can become awkward for people who use handheld devices. This is typically because most of these user interfaces are designed for devices like laptops rather than handheld devices.

The improved interfaces could support “app-style” login experiences including “remember-me” login experiences where applicable. Other improvements that could be facilitated include the use of barcodes that are scanned by the phone’s camera to load “session keys” for docket-controlled hotspots or MMS direct-load support for login tokens for “SMS login token” WISPS. It could then lead to a venue-branded experience which some users may find as a “safety net” for their hotspot experience.

As well, a branded experience can be part of a “walled-garden” of sites that a person can visit free of charge or can be a sophisticated experience with such things as an online menu or the ability to order food and drink from your computing device.

Similarly, the idea of “franchising” WISP service to owners of venue-controlled hotspots hasn’t been worked out fully with this technology. Here, a person could have the rights to resell a WISP’s service under varying risk-return models and have the clients associated with that service use their hotspot in exchange for a cut of the costs paid by the clients.

Selective device-cluster creation

It is also a preferred standard to have devices in a public network isolated at lower network levels in order to prevent unwanted peer-to-peer discovery of the devices on these networks. This is typically achieved through functions like “AP isolation” or “Wireless Network isolation” and makes it appear to the devices that they are connecting directly to the Internet privately.

There are situations where a person may want to provide local connectivity between their own devices or devices owned by other users that are in their trust circle. Examples of this include LAN-based gaming over a wireless hotspot network, workgroups sharing data during a cafe meeting; one shifting data between a smartphone and a tablet computer at a coffee lounge or simply uploading pictures from a Wi-Fi-enabled camera to a 13” traveller laptop at their favourite “watering hole”.

Here, the authentication needed for this could be achieved through “same-token” login for devices with integrated Web browsers to entry of MAC addresses or WPS PIN numbers into a “cluster-creation” screen provided by the hotspot gateway. The Wi-Fi Alliance could examine the feasibility of using the new authentication methods as a way of creating selective network clusters across a device-isolated public wireless network.

Authenticating hotspots at the SSID-discovery level

The other question that has not been answered as far as I am concerned is whether there will be a system for authenticating hotspots and public networks in a similar manner to what is done when a user logs on to a banking site for example. This is to verify that the user has discovered a “safe” network before they select that SSID and begin to login to the hotspot.

The data that would be verified would be the MAC addresses of the access points as well as the gateway device’s  IP address and MAC address. This can be used to verify that the user has logged in to a network that is operated by the venue that is providing the hotspot service. For a WISP like “The Cloud” or FON, this may be useful for verifying that users have logged in to the WISP’s network. In this case, this information may pertain to the locally-installed hardware for the WISP.

Here, this could be achieved through a private-key / public-key exchange setup where the successfully verified hotspots could at least be highlighted in a wireless network with a ?key” or green-light icon. If this system does also support the transmission of logo icons, the client device could also show a company logo for that hotspot host.

It can also work as a way of encouraging customers to be sure of where they are surfing the Web through. As well, a business could have a Windows 7 laptop or Blackberry smartphone that supports this kind of verification for public wireless networks to prohibit logging in to public wireless networks that don’t have this kind of verification.

The main issue with this is that independently-run cafes and bars may need to be able to have access to any certification setups at a modest price, preferably through a government business-support agency or their bank.

Conclusion

Once these issues are ironed out concerning the provision of public Wi-Fi Internet service to the hordes of users with notebooks, netbooks, smartphones and tablet computers, then they can use these services to full capability in a secure manner.

Toshiba Portege R835-P56X Review – Laptops – CNET Reviews

My Comments

There is now a “race for the best” going on with the 13” “traveller / hotspot-user friendly” class of laptop at the moment thanks to the new Sandy Bridge technology. This is even though the netbook is appealing as a The gauntlet had been laid down by Apple with their latest MacBook Pro laptop for the MacOS X platform and everyone is trying to match this goal in an affordable way.

Examples of the improvements we will see with these computers will be improved video performance as well as an increase in the runtime available for the computer on its own battery. Some of these machines could allow for a hot-footed workday without the need to look for power outlets so you can charge up that laptop.

An example of this is Toshiba’s Portege R835-P56X laptop which uses this technology. The CNET review posted improvements in battery life by 3 hours over the previous model as well as video performance. This battery runtime period that was quoted for the Toshiba when running a video clip was nearly 8 hours, which would cover a typical workday of hotspot-surfing or public-transport working. It also is ready for USB 3.0 and can work with Wi-Fi N wireless networks.

Yet this machine still comes with an integrated DVD burner as well as 4Gb RAM and 640Gb on the hard disk. This capacity may be important when you take those digital pictures and you want to “dump” them to the computer for editing and uploading while on the go. But users may have to check their configuration comes with integrated Bluetooth when they “spec” the unit they want if they do want this function. This would be more important if you do want to pass audio to an amplifier using a Bluetooth A2DP audio module, use your favourite Bluetooth headset to Skype with or use this technology to “tether” your mobile phone to the computer.

At least the new Sandy Bridge technology could allow for this class of laptop computer to improve and become more appealing to those of us who create content while “on the go”.

Labor backflips on its NBN promise to regional Australia | The Australian

My comments

Rural and regional Internet users are being short-changed again by a backflip that Labor has done with the National Broadband Network.

The kind of treatment rural and regional users receive

This is an example of continual second-rate treatment of rural and regional citizens when it comes to telecommunications.

Here, I remember living in the country in the 1980s when there was continual poor-quality telephone service. Here there was a poor signal-to-noise ratio with the phone line to where I lived at and this usually manifested in a lot of crackling through the call as well as frequent incidents of crosstalk which we often described as “crossed lines”.

As well, if rural users want to contact services in metropolitan areas, they have to pay long-distance telephone rates for these calls. This is unless the service provider sets up a freecall or local-cost telephone number for people to ring in on.

Continuously, country users are limited to dial-up Internet and this is often at a substandard rate with slower-than-standard data speeds and longer connection-establishment times.

As well, country users cannot benefit from broadband because they are usually out of the proper “range” for ADSL services. Therefore they end up on the substandard dial-up services. If they are in “range” for ADSL service, they end up with substandard ADSL service.

What is happening with NBN

The Labor federal government had built their election campaign on the back of the National Broadband Network. This was to have the same cost of service across all of Australia even though the service will be provided “to the door” using fibre, wireless or satellite technologies.

Now they have done a backflip on this promise by not guaranteeing a price structure that requires the Internet service on this network to be the same for metropolitan, regional and rural areas. This is based around the excuse that the wireless technology that would be needed for the regional and rural areas will cost more to set up, especially in licensing costs.

I have seen some successful operations in the UK where next-generation broadband services have been rolled out to some rural villages in a cost-effective manner by local companies. Here, they had worked on the local deployments using technologies like VDSL-driven fibre-to-the-cabinet yet allowed the systems to be future-proof for fibre-to-the-premises.

The use of “anti-competition” measures in the NBN legislation would make it hard for a “go-getter” company to do what companies like Rutland Telecom have done in enabling rural towns with next-generation broadband.

Supporting the rural Internet needs properly

What needs to happen is for these measures to be adjusted to expedite service delivery to rural areas and facilitate the NBN or government to support local entities in deploying such technology to rural and regional areas. Then could then be able to provide retail service in to these towns or lease-back the infrastructure to the NBN for wholesale service provisioning.

As well, if there is an easement required on a property for running fibre trunks in the NBN infrastructure, the issue of fibre branches connecting “to the door” of the affected as well as adjacent properties from this trunk should be looked at.

The NBN doesn’t even look at the issue of a genuine “universal service obligation” concerning broadband and there needs to be activity concerning this issue. This includes a minimum standard or service and a maximum price for the service similar to what is being prescribed in Europe. The costs could be offset via a universal service fund which could be supported either through line spending or a direct levy like one on service-provider turnover.

Conclusion

It therefore seems to me that the Australian government have lost the plot when it come to assuring competitive Internet access and a universal standard of Internet service in the country. They need to look at what other established countries are doing for when it comes to these factors and implement these issues effectively.

Introduction

I am reviewing the Rotel RCX-1500 network CD receiver which is one of the first “big-set” hi-fi units that I have reviewed that can do proper Internet radio and benefit from the DLNA Home Media Network. Previously I have been reviewing Internet radios that are mainly “small-sets” which are table / clock radios or portables and are intended for use as secondary or auxiliary audio devices.

The product class

This unit is infact a CD receiver, a class of “single-piece multi-function” hi-fi music system which continues from where the music centres and casseivers (receivers with integrated cassette decks) of the 1970s and early 1980s left off. Here, some of these units were equipped with the functionality and quality of modest separate-unit hi-fi systems yet they offered this in a single box, which you could just hook up a pair of speakers to. The manufacture of high-sndard pieces of this class of equpment had diminished through the late 80s. This is although Bang & Olufsen were consistent in this field at a premium price and a few other manufacturers like Proton, Bose and Onkyo were releasing in to their model ranges  one or two receivers with integrated CD, tape or MiniDisc transports that weren’t just second-rate music systems.

Then there had been a slow but sure renaissance in this class of good-quality integrated-function hi-fi equipment as the trend for “downsized” living especially in “executive” city apartments became more intense. This is where most of the good hi-fi names ran with at least one CD receiver in their line-up that didn’t come with a set of substandard speakers and this Rotel RCX-1500 that I am reviewing is one such piece of equipment.

Price

Unit alone: AUD$1999 (recommended retail price)

Speakers (Cabasse Antigua MT30): AUD$999 / pair (recommended retail price)

Functions

Connections

Speakers

This unit was tested with a pair of Cabasse Antigua MT30 bookshelf speakers connected using premium audio cables. These speakers were also on loan from the distributor so I can review this unit properly. They are built using an orthodox two-way driver arrangement and use a bass-reflex enclosure and can work with amplifiers that have a minimum power output of 75 watts and maximum of 500 watts. As far I was concerned, these speakers worked very properly with all kinds of music and could yield a decent sound for their size.

The Rotel CD receiver

Functionality comments

Slot-load CD player

It is also worth knowing that this CD receiver has a pair of pre-out connections so one can connect it to a more powerful and better-sounding power amplifier or a pair of active speakers like an active subwoofer or some of the active speakers like B&O’s Beolab range or any of the Bose Powered Acoustimass speakers.

It can connect to your home network via Wi-Fi or Ethernet using supplied network-adaptor dongles. The Ethernet option can also allow it to be used with a HomePlug AV network segment using an appropriate “homeplug” adaptor and I would recommend this as a “no-new-wires” option for connect this CD receiver to the home network.

This functionality allows this CD receiver to provide Internet radio or work with a DLNA-compliant media server that is on your home network. The only limitation with this function is that it doesn’t work as a MediaRenderer which means that you have to select your network media using the Rotel CD receiver’s display.

The tuner is “up to the minute” with broadcast radio in Europe and Australia by supporting FM RDS as well as DAB+ radio. There are two antenna connections for both FM and DAB but you can choose to use the FM aerial for DAB. It came with two aerials – the typical “T-wire” for FM and a small whip one for DAB. With this one, it was able to pick up Melbourne’s DAB multiplexes reliably as long as it was near a window.

But I would rather that this unit be connected to an outdoor aerial especially for FM reception so it can provide clear signal reception. You may also be able to use a digital-optimised Band III aerial for better DAB+ reception especially on fringe areas.

You can connect an iPod or iPhone to the front USB socket using the data cable supplied with your Apple device and the sound that is played off the iPod will be converted to an analogue form using the Rotel receiver’s internal digital-analogue converter. As well, this same socket is used for playing music held on USB memory keys.

The CD player is a slot-load type that performs as expected for a decent-standard player. It can play the regular CDs or file-based MP3 discs and gives “best-case playback” for any CDs recorded with the HDCD mastering technique. This does yield to high-quality sound from these discs.

As for connection of external equipment, this is feasible with a line-in connection in the form of RCA connectors or SPDIF digital in the form of coaxial or optical connectors. There isn’t a line-out connection that is independent of the volume control for use as a recording connection, which may limit this unit’s utility with cassette or MiniDisc decks.

It is also controllable by a supplied remote control which has a numeric keypad for direct access to 30 presets in each of the radio bands – FM, DAB and Internet. As well, this remote also allows for direct access to tracks on a regular CD and is a preferred control surface when you are searching content on a well-stocked media server or using the CD receiver’s setup menus.

The unit's remote control

This unit’s amplifier is engineered for sound quality. Here, the volume control is a motor-driven potentiometer managed through the control on the front or the remote control. There aren’t any tone-control options, which may please audio purists who believe that tone adjustment affects sound quality.

The display is the white bright fluorescent display but uses four lines of text. This also works with the menu-based operation for advanced functions.

Sound quality

The sound quality for the Rotel RCX-1500 CD receiver is what you would expect for equipment in its class. This is even so with the Cabasse Antigua speakers that I am testing this unit with.

It comes across as being tight and good across all frequencies. This means that it gives all the instruments in a sound recording a proper chance rather than sounding like the old pub jukebox. This has come across so well with well-recorded rock like Peter Gabriel’s “1 – Car” album which was considered to be in the same league as Pink Floyd. Here, you still had that “punchy sound” while hearing the vocals and other instruments.

This system was even performing well with classical music especially as I was playing through a recording of Beethoven’s Violin Concerto which was done with “period” instruments. Here, the combination of this CD receiver and the Cabasse speakers shone through the whole of this popular concerto and was clear with all of the instruments.

As for handling the audio codecs, this amplifier answers the requirement for handling properly-encode music properly especially if you use the “maximum” throughput settings for the codecs like 320kbps MP3 or 192kbps WMA.

Limitations and points of improvement

The network connectivity could be improved on by not requiring the user to deal with easy-to-lose dongles. This is more so with Ethernet as most Internet-enabled hi-fi components and TVs use integrated circuitry with an Ethernet socket on the back.

As well, the Rotel could benefit from WPS setup for Wi-Fi wireless networks especially as most current-issue routers implement this easy-to-use setup method.

An improved version of this unit could support a proper tape loop and a phono input for use with a turntable especially as a lot of the older people may keep records or tapes lying around and could benefit from a simplified system with these inputs.

Conclusion

This is one network-enabled CD receiver that I would recommend for people who have a pair of good-quality bookshelf or “piece-of-furniture” speakers that they wish to keep going but want to benefit from newer sources like music held on their home network or iPod; or Internet radio. I would also consider this unit as a the core of a simplified music system if they want to choose their own good speakers.

This unit, along with the Cabasse Antigua speakers or bookshelf speakers of a similar standard, would be an ideal simple music system for use in an apartment or small house by people who place high value on music. It is especially more suitable with older retired people who are moving towards smaller flats or retirement villages.

The UPnP Forum have established a printer device class in the early days of this standard and have provided an “improved-printing” service for this device class. This was an attempt to allow a device to print text, Webpages and photos without the need for the device to have printer-specific drivers.

I know that a lot of Hewlett-Packard’s network-enabled printers in the Photosmart range like the Photosmart Premium Fax C309a support this functionality. This also includes the HP Envy 100 printer which I have just reviewed. Some other manufacturers like Epson may support this functionality in a few of their products.

The reason that there is inaction concerning the UPnP Printer device class is that there aren’t enough client devices that properly support this function. So far, some of the Nokia phones that work on the Symbian S60 Third Edition platform like the N95 and N85 can print photos to these printers using this platform. But I know of no other devices or platform apps that exploit this functionality.

Key enabler for this device class

Platform devices

An increasing number of manufacturers are moving towards the use of device platforms like Android and Maemo as the baseline operating system for embedded-platform devices like set-top boxes, PVRs and TVs as well as smartphones and tablet computers. These platforms typically use “apps” as a way of adding functions to the device, effectively turning the device into something that resembles a general-purpose computer. These “apps” are typically written by third-party developers and provided through an “app-store” or similar menu that is hosted on the device, either for a low cost or, in a lot of cases, for free.

These platforms, save for the Apple iOS platform, don’t have a printer-interface function that these apps could exploit and what is happening is that printer manufacturers are writing photo-printing apps for these platforms that work with their devices. They can support the UPnP Printer Device Class as a printing interface rather than reinventing the wheel for this function.

Key applications

Hardcopy from the tablet computer

As the tablet computer becomes increasingly popular amongst home and small-business users, there will be a requirement to turn out hard-copy from the apps loaded on these devices. Examples of this include printing emails or chapters from ebook apps to printing out photographs taken using the device’s integrated camera.

At the moment, the iPad can work with AirPrint-enabled printers like the HP Wireless-E B110a, the HP Envy 100 and the HP Colour LaserJet CM1415 that have been reviewed in this site. Windows 7 tablets can use the conventional driver-based Windows printing platform but Android and WebOS tablets don’t have an integrated printing platform. Access to the printers for these platforms is through photo-printing apps which are limited in purpose because they only print photos or, in some cases, PDF files; and are also tied to particular manufacturers’ printers.

If Google, HP or other companies who are behind tablet-computer and smartphone operating systems implement the UPnP Printer Device Class, they can add a driver-free printing ecosystem to these operating systems.

Hardcopy for Interactive TV

As the TV set becomes integrated with the Internet, there will be an interest in interactive TV. This will allow the viewer to interact with broadcast material using their remote control. Initially, it is being used with some broadcast-TV set-top boxes that use a cable-TV or dial-up-modem return path to facilitate purchasing of pay-per-view content or increasingly to allow viewers to register votes when they watch panel shows or talent quests. The Internet path is increasing the interactive TV abilities through the delivery of extra material to the viewer, thus permitting concepts like “catch-up TV” and on-demand availability of extended interviews and supplementary material. It is being augmented by set-top boxes, PVRs and TV sets (especially the main-lounge-area ones) being equipped with network connectivity.

The UPnP-enabled printer can work well with Interactive TV by offering a hard-copy option for editorial and advertising content. In the case of editorial content, this could lead to the availability of factsheets, end-of-show leaderboards and similar material.

The best example of this would be MasterChef, the popular cooking-based reality TV show. In a typical season, there are many recipes that will appeal to one’s tastebuds and may “fill in the gap” for a cooking situation that may be particular to one or more viewers. Here, the viewer would have to go to the MasterChef website using their computer and search through the recipes for the one that interests them in order to print out the hard copy they need to work from when they build their shopping list and when they cook the dish in the kitchen. It could be made easier by the viewer pressing a button on the Interactive TV remote control while the recipe is being cooked to have that recipe printed out, or obtain a recipe list for this current episode so they can choose what to print out.

Even the commercials could be augmented with “print-to-redeem” coupons, “specials lists”, factsheets and product-disclosure notices that the viewer can print out at the touch of a button when they see the ad. This can be extended to programs like game shows or talent quests that exploit viewer participation and use “print-to-redeem” coupons as incentives for viewers who participate in these shows.

Games and apps that are part of the interactive TV experience can be augmented with hardcopy options. Examples of this could be skill-based games that reward users with prizes for successful completion or being at the top of the game’s leaderboard; or apps that provide hardcopy information on demand.

Companies who are behind interactive-TV platforms like those involved with Internet TV could implement UPnP Printer Device Class in order to open up the possibilities offered with hard copy for Interactive TV.

Hardcopy snapshots from digital cameras and electronic picture frames

The UPnP Printer Device Class offers the ability for a connected electronic picture frame or digital camera to print snapshots through an existing home network rather than having to use “peripheral connections” like USB or Bluetooth.

This can avoid the need to locate a frame that receives “new” images via email or online services near the printer to print out the snapshots. Similarly, one could print out snapshots taken with a Wi-Fi enabled digital camera or mobile phone without worrying about whether the camera will work with the printer. This would be more acceptable for people who like creating “picture walls” from special events that they host. These “picture walls” are collections of pictures of the event taken by guests that are stuck to large sheets of cardboard.

Conclusion

But there are more applications like the ability to obtain a copy of a “dashboard” screen from a monitoring device through to “on-demand” news-printing from other devices. It also means that the UPnP Printer Device Class can open up paths for innovation when it comes to the functionality roadmap for a device targeted at a home or small-business user. As well, the UPnP Printer Device Class can also be useful as a “generic printer driver” for general-purpose computers so that basic text and graphics print jobs can be turned out without the need for awkward print drivers.

What needs to happen is that companies need to get serious about implementing this device class in their printers, computers and network-enabled devices.
