Bringing the School into the Home via Broadband

As Britain moves closer to complete broadband coverage, communities around the country are beginning to explore the potential that interactive services offer and are partnering with technology companies and content providers to create some innovative services.

We decided to look at one of the best examples of community broadband TV: Kingston Communication’s collaboration with an East Yorkshire school which has led to an exciting project to engage pupils in interactive learning, both at home and in the classroom.

The Kingswood High School’s Broadband TV (KBTV) Project was conceived in 2001 under the UK Government’s Information Society Programme and Hull’s own Digital Learning Plan. Kingswood was chosen to collaborate with the BBC in its Headstart project.

The BBC provided the school with access to its film and video archive – and from this, using standard desktop tools like Premiere, pupils and teachers were able to create interactive content that formed the basis of many exciting and informative lessons.

Kingswood High went on to develop the idea into community broadband TV – with the aim of providing a range of interactive services via set top boxes (STBs).  The school secured enough funding for the project to provide a one-year trial of STBs for all the families in the local community with a suitable phone line.

We spoke to Andrew Fawcett, Head of Products and Services at Kingston Communications about the stealthy growth of broadband television: “IPTV has come of age, and it’s come of age in a non-linear fashion.  We’re on both sides of the equation, because part of our business is being a broadband ISP, and that’s been experiencing exponential growth, delivering one megabit of broadband to a consumer PC.  Since 1998, we’ve been delivering five megabits into the back of people’s television sets with a service that people don’t know is broadband.”

We asked him for some background to the Kingswood project: “Everybody who goes to Kingswood School, all the kids basically as part of their school work, use the KIT service – it’s given to them free of charge.  They’re creating their own content at school level.”

“The service covers 200 homes at the moment, but we have a proposal to roll it out to 2000.”

Staff at the school are finding that this new way of learning reaches and appeals to children who would not normally enjoy or benefit from traditional classroom teaching methods.

The interactive service provides immersive learning tools at school and at home. Andrew added, “They (the pupils) get the Kingswood Channel, a school’s TV channel with three elements to it.  One is that we deliver curricular materials – there’s a permanently available set of resources for all subjects that’s very video rich.”

“The second part is taking stock materials and turning them into their own programmes.”  Each (school) year has its own area on the service, though areas are accessible to everyone.”

As an example of this, Andrew showed us a documentary on arson that had been created at the school.  The film had been constructed from content that was put together by the school’s pupils and teachers.

Part of the experience of learning about arson includes the kids going out with cameras and interviewing people.  The idea of making children media literate is very powerful. I’ve seen kids who would be a nightmare in class, but this stops being class work, and becomes making a film – and more importantly it becomes a film that’s going to be on live telly when they get home.  You can suddenly engage kids at a level that’s incredible.  Very significantly, the school comes into the home.”

The film included an interview with victims of arson, and an arsonist – and was put together with standard desktop tools like Adobe Premier.

Interactive television like this also provides educators with valuable information on the effectiveness of services and lessons.  “Year Ten”, he told us, “will be asked to go home and watch this as homework.  We track usage for a select number of pupils who have chosen to opt in to the research elements in the programme.  We’re looking at Educational Family Footprints.  One of the key determinants of the success or failure in education is parental support.  We’ve taken families with different educational footprints – from homes where education is core to the family life, to others where education is less important.”

The third aspect of the service provides pupils with a virtual PC they can access using their television set at home.  The system runs a virtual PC using Citrix MetaFrame – all the processing is done at the server end of the network, which only sends screen updates to the set-top box.  The box essentially becomes a “dumb terminal”.  Pupils can access and save work stored on the school’s network, and use Star Office providing them with applications for word-processing, spreadsheets and presentations.”

A virtual PC service like this has many advantages, as the customers don’t have to maintain a PC at home and so security against spyware, hacking and viruses is taken care of by a qualified IT department at the school.  It also ensures that pupils all have access to the same computing platform.

Andrew is justifiably proud of this aspect of the service, “Of all these things we’ve done with KIT, this brings everything together.  It brings the localness and on-demand aspects of the service together, and it emphasises the difference of broadband TV – you could never provide an application like this with satellite TV.  It’s wholly back-channel dependent.”
Kevin Beaton, Head Teacher at the school explains why they wanted to get so involved in a service like this:  “The rationale for the whole project is that the school becomes the local hub that is able to provide the surrounding community with access to digital services. Initially the focus will be on education, so that we can prove to everyone involved that the principle of on-demand access to information and interactive educational content really is viable.”

Vein continued, “The school is currently developing material to be used on KBTV, and we’ve identified a number of logical and consistent uses for the system. Lessons in several departments are already being developed using our very latest interactive ‘White Boards’. This in turn means that teaching methods and the style of learning are changing, and more and more lessons will begin to make use of film and video as a stimulus to greater creativity. Some of the items will only be produced for homework purposes; hence students would be expected to watch educational material on film, and then complete set work on the film at home. Other material will be work from lessons at school, which can be completed at home, or perhaps reviewed at a later stage as part of a planned revision programme.

“Yet other material will be demonstration work from subjects like Design Technology, where soldering small intricate parts can be clearly be shown to pupils in close-up mode. In the field of Art it would be possible to view many different examples of paintings and sculptures, with the key points that ensured the success of the work clearly demonstrated.

“Another interesting aspect of the KBTV on-demand channel is that parents would have independent access to vital school information concerning their children. This would include attendance records, term dates, coursework deadlines, examination entries, parents’ evenings, exhibitions and school music and drama productions. In addition, direct contact could be made with school staff via e-mail, with the possibility of video conferencing for those parents or guardians who were unable to physically visit the school for whatever reason.”

And what about the future for services like Kingswood?  Andrew Fawcett told us what was up next: “There was a very small budget for this – by squeezing things, as we tend to do, we managed to deliver it to 200 homes, to get a reasonable feel for the potential.  This stage of the trial finishes in June – our intention is to look for additional sources of funding.”

Kingswood High and Kingston Communications are compiling information on the before and after effects of the KBTV initiative – hopefully benefits of this sort of programme will inspire more partnership and research in the educational possibilities of our broadband future.

Netflix Switching to Web Delivery

Netflix, the online DVD rental firm has plans to deliver films via the internet by 2005: “Our strategy is to get huge in DVDs and then expand into downloads,” Reed Hastings, Netflix Chief Executive, said to Reuters.

Netflix’s business model currently operates around the postal service – users browse the Netflix site, selecting titles they wish to view. DVD’s are then delivered to the company’s 1.9 million subscribers by post. Cutting out the postal service will pay for online delivery and allow Netflix to invest in more content. Hastings estimates that a download service will have 5 million subscribers by 2006.

Netflix currently charge US$20 (€17) a month for their postal-delivery service, and are proposing a US$22 (€18.50) per month charge for their download offering.

Netflix don’t want to download to computers, instead using a broadband connection direct to the TV set-top box – rather like Blockbuster’s unique VOD service in the UK.

Competition is going to be fierce – more movie download services are in the pipeline and Netflix will have to go up against strongly-backed groups like Movielink and CinemaNow. Movielink was formed by five major studios: MGM Studios, Paramount Pictures, Sony Pictures Entertainment, Universal Studios and Warner Bros. CinemaNow counts Microsoft and Blockbuster amongst their investors.

Hand-held Digital Video Broadcasting – a summary of progress at DVB World 2004

The fourth Digital Video Broadcasting World conference was held in Dublin last week – and one of the key topics discussed was the developing standard for broadcasting digital video to hand-held and other mobile devices.

The new standard was only conceived two years ago, and after a couple of name changes (it has previously been known as DVB-M and DVB-X), has been named DVB-H. The standard was accepted by the DVB Technical Module in January and is expected to be submitted to the European Television Standards Institute this year.

As the standard is still so new, there are still some problems to be ironed out, mainly power consumption and some network issues.

DVB-H’s core function is the delivery of digital media to small and portable devices such as mobile phones, but without using mobile phone networks. It has been designed to deliver MPEG-2 streams, but can broadcast any type of data.

The proposed standard addresses five issues with mobile devices: they tend to move about, they have smaller screens, they have smaller antennas, they require indoor coverage and they run on battery power.

DVB-T (the terrestrial standard for digital broadcasting) was not really considered for mobile video as it was designed for use with rooftop antennas and does not have the building penetration required, nor is it very power efficient. In theory it could be used to broadcast to mobile devices but a separate dedicated standard would allow many optimisations, rather than just bolting on functionality to a standard that was never actually designed for mobile use.

DAB was designed for devices with similar location and power demands, but simply does not have the spectrum width to carry the data required.

Another interesting aspect of DVB-H is that it can coexist with DVB-T without disturbing devices using the other stream, such as set-top boxes.

DVB-H uses time-slicing between streams to reduce power consumption, but this saving is more or less lost when the total bit rate for a service is low. It’s designed to carry only IP (Internet Protocol) services, so is obviously constrained by the capabilities of the carrier protocol – but since IP is well understood and supported, and has a rich set of features such as strong encryption, this should not present many problems.

As we said at the beginning, the standard doesn’t use existing mobile networks to deliver content, but we should add that it also needs more masts than conventional broadcasting (though less than cellular coverage, and the masts need not be as large as conventional broadcast masts). It is expected that existing cellular masts will be upgraded to transmit DVB-H signals. However, the cellular network will provide the return path, allowing users to pay for content and receive licenses for their purchases.

Presented at DVB2004 was the Nokia’s 7700 is the first device to support DVB-H through the addition of their Streamer SU-6 accessory. The SU-6 is attached to the 7700 like a battery pack and is just the beginning for devices that will provide new forms of multimedia and entertainment for consumers.

Ofcom Chair: UK with True Broadband by 2010

Fifty days in to Ofcom’s existence, its Chair David Currie delivered a speech to the Communications Management Association conference. He recapped on what Ofcom had been doing, then outlined where he felt it was going, focusing mainly on broadband.

We feel the most exciting part of the speech was, in his words, True Broadband.

Anyone with a real understanding of why broadband is such a vital part of the future will be hugely encouraged by his words. In summary, what is currently being sold as broadband to the UK consumer and many other around the world, a 512k connection, is not broadband. It is the equivalent of a 1200/75-baud modem.

We heartily agree with Currie view that ‘DSL at 512k is a convenience product’. He argues that it is not practical or possible for the UK to lurch from a 512k connection to something much faster – the current copper-wire based system we have simply would not support it.

Instead a target of 10Mbps should be set for 2010 and that it should be provided competitively. We read this as; the long lasting monopoly that BT has, and does enjoy will be removed. His comparison with the multi-supplier mobile market bears this out. In our view BT consistently hoodwinked Oftel. At first glance it looks like they will not have the same joy with Ofcom.

This was further underlined by his praise of the Parliamentary Trade and Industry Select Committee point that

‘[we must] make certain that the regulatory framework ensures that commercial decisions by private companies are aligned with the wider economic and social needs of the country.’

He and his colleagues clearly recognise and understand what is required for a proper broadband service. With connections being symmetric rather than the slow transmit, asymmetric we have now, he identified the need for the network to enable distributed system, not just central services delivering to the ends of the network. We also find it encouraging that he reiterated the pursuit of wireless connections.

Currie states his aim is ‘Liquid bandwidth; all you can eat; always on. No contention.’

Very encouraging.

Telewest Float Surf & Sniff Smell Generator

It being Friday and we thought we would bring you a light-hearted piece.

UK cable company, Telewest, has suggested that they may release a computer add-on that generates aromas that can be controlled software. Sound like an urban myth/joke, but it is not without precedent. The first time a computer-controlled device was suggest was in 1999 by a start-up called DigiScent. Prior to that it was on the grander scale of whole cinemas, when in the last 50’s two similar ideas, AromaRama and Smell-O-Vision, were introduced to US cinemagoers.

AromaRama used the theatres ventilation system to get their scents out and Smell-O-Vision far more expensive approach was to place units under each cinema seat.

DigiScent was a serious, scientific approach to the subject that was started by two Stanford graduates that had made some serious fortunes from software for genetic databases.

One of the founders, Joel Lloyd Bellenson looked into previous scientific research around the subject to discover how humans perceived smells. His explanation was detailed in an article by Wired at the time.

“The explanation for this proved relatively simple. When odour molecules drift into the nose, each of them binds with a particular protein on the surface of a neuron. There are about 1,000 odour-matching proteins, each with a slightly different configuration, scattered across a human’s 10 million odour-detecting neurons. (By comparison, a mouse has about 1 million neurons of this type, while a pig boasts 100 million.) When the shape of an odour molecule matches the shape of a protein, the molecules lock together, triggering the neuron, which sends a signal that the brain recognizes as a smell. DNA is relevant because its instructions – its genes – tell the body how to build the proteins that receive odour molecules and activate the neurons. ”

Calling on his previous software experience, Bellenson wrote software to simulate the binding of odour molecules with proteins. By using this he felt he could generate billions of odours simply by selecting different proportions of 100-200 “scent primaries.”

DigiScent’s business was to licence its software to the creators of  other media, to synchronise aromas with them. Web pages would be able to trigger them, as would TV shows, video games and films. The scent generators would be plugged into the serial port and sit on the desk – Reekers, instead of speakers.

Like many ideas around 1999, sadly DigiScent is not around anymore. One possible reason for that could have been is the name they chose for their product – iSmell.

Telewest say they have tested the idea in their labs, calling email using the device ‘ScentMail’, or on a wider scale, ‘Aromanet’. They plan to bring out a domed device that plugs in to the serial port of a computer or set top box, that takes dispoable cartidges to generate the aromas. They say the intial range of smells will be around 60 by mixing the palette of 20 oringial aromas.

Appearing to be designed to get them a few column inches for their broadband service, it is not clear how serious Telewest are about it. When discussing the cost of the dome they are less than exact, ‘Hardware for a surf & sniff set up might cost around £250 for the basic equipment’. We are sure Telewest is not trying to create news during the time their managing director, Charles Burdick, has left the company to “pursue other opportunities.”

Akimbo Launch PVR-over-IP Box

Akimbo Systems launched their television-via-Internet service yesterday at Demo2004. They are claiming the service will start with over 10,000 hours of video content, organised in to 50 categories, will be pulled from a variety of sources. The number of hours available will grow to 20,000.

The $199 player, which is expected to be in US retail stores in late 2004, receives content via a broadband connection and can hold 200 hours of video, in Microsoft’s WM9 DRM-controlled format on it’s 80Gb drive. Subscription to the service is $9.99 per month.

This product is the first of released example of the long spoken about idea of distributing content by passing previously used broadcast structures. Akimbo claim a number of factors have now come together to enable the services to become realistic; the cost of transporting a gigabyte of video over the Internet has dropped to around $1 from $20 a few years ago; video compression has improved to the point that DVD-quality video can fit into a 1.5 megabit per second stream; broadband has grown to an audience of 50m people.

Given it is initially a dedicated box, that we assume will be closed to customer enhancements, it will live or die by the content they can secure for the service. We suspect the service may well morph in to a content channel when more PC’s are connected to the TV in the lounge.

Akimbo are canvassing for new content from video rights owners and are giving the option for subscription, rental, purchase, or advertising supported model. Their big pitch is niche content direct to the consumer and they will handle transactions, delivering the due fees to the rights holders.

We feel the other vital component for them to get right is the navigation of the content, enabling consumers to actually find the programmes that they want to watch.

Sony Announce Location Free TV

Among the many announcements at CES was an interesting portable 12″ LCD TV screen from Sony, that can be carried around a house and have various content delivered to it from its base station, enabling the showing of video from many different sources, as well as playing music, viewing photos and browsing the Internet. Sony calls it LocationFree™.

It is based on a similar device released just in Japan called AirTact and a few TVs. Kunitake Ando, president and group COO at Sony Corp has realised the potential to freeing the screen. At Sony “Dream World” held in Paris, Sept. 2003 was quoted that transforming traditional TVs to “location-free” TV or displays could take the 125 million TV sets sold worldwide and “easily increased to four or five times that number.”

The basestation can have many different sources plugged in to it, including; video, be that TV ariel/cable, DVD, VCR, DV video camera; audio sources; other media files stored on computers via Ethernet. There is a wide selection for possible connections to the network, wirelessly (802.11a, 802.11b (WiFi), or 802.11g) or an Ethernet cable. The content is delivered to the remote, battery-powered 12.1″ LCD touch screen, which can also run from a main source. There are also plans for a pocket sized 5.8″ version. The viewer is free to move around the house while continuing to access the different media sources, selecting them by touching the screen. As yet, Sony has not discussed battery life.

For the first time Sony have brought technology from their high-end TV sets to the LCD display including 3D Y/C separation circuitry for clear, vivid picture and colour blur reduction; angled line correction circuitry for smoothing out jagged lines; motion adaptive I/P conversion circuitry for improving fast moving action scenes; and digital audio amplifier circuitry for crisp sound and minimized distortion.

It looks like Sony have carried out considerable research to find what function user may want. The five pounds screen itself has a lot of connectors includes an Ethernet port, a USB port, Memory Stick media slot, headphone jack, keyboard port and an AV input for connecting to a camcorder. Useful features include viewers being able to “freeze” and save a TV scene by using the “capture” button on the remote screen – saving a mad scrabble for pen and paper where information appears on the TV.  Prints of the images or homepage data, e-mail attachments and digital photos can also be made to USB printers connected to the base-station.

While using the screen to browse the Internet, the viewer will be able to watch their choice of TV/video source displayed in a Picture in Picture (PiP) window, but given the screen is 800×600, we imaging this might not be used much beyond demos to friends.

Sony has omitted to give any precise dates for the shipping of Location Free, preferring to say it would be “Later in the year”.

Sony say one of the benefits of the screen being an IP device is that access your media does not need to be restricted just to your own home network. By taking the screen with you on your travels, you can access the self same content through any IP connection, which are increasingly found around the world in offices and hotel rooms. One example cited gives an interesting twist to the product – a person on the road, unable to attend their child’s birthday, has an opportunity to tune in, watching the live video being shot on a camcorder plugged in to the basestation at home. We believe application such as this, which can be used to bring together families distributed over great distances, will be a major driver in purchasing products.

We are excited about this step of remote access to your home media, firewall configuration allowing of course. It could be an interesting early step into a future where your home media server becomes the focal point of your media ownership, with your various remote IP devices having access, via your home server.

At this point it is worth highlighting that hard facts about which protocols are used to transfer content back and forth between base-station and screen. It would be a great shame if the protocols were proprietary. We think there is real potential in this device, and by using open standards; there could be a real potential for a product like this to become a standard for interfacing analog media to an IP device. There is a real need for a device like it and it appears that Mr Ando at Sony Corp is trying to fill it.

Two companies signup for Microsoft IPTV trial

Two new companies have signed up with Microsoft TV to trial their latest Internet Protocol Television (IPTV) offering. Reliance Infocomm, part of the Reliance Group, the vast Indian conglomerate with US$ 16.8 billion yearly revenue, and Bell Canada a Canadian Cable company, both plan to use their networks to offer TV services. Bell Canada will be the first North American Telco to try the Microsoft solution.

The details of the India trial are not clear as yet, but Bell Canada plan to begin testing with subscribers on their “early adopter” programme, who live in six chosen apartment blocks in Toronto. The Canadians will get to use the Microsoft TV’s Interactive Program Guide (IPG) and video on demand (VOD).

Microsoft feels that they offer a complete end-to-end solution based on Windows Media 9, enabling telecom and cable companies to quickly get involved providing television services over their existing networks. Their previous offering have not been too popular, but they are putting lots of effort behind this version.
