IBC Report – DVB-T2: a possible home for the DVB’s next-generation handheld standard?

Posted by Barry Flynn on September 13, 2009 No comments

Connected TV met up at IBC for the first time with Peter Siebert, who recently took over from Peter MacAvock as executive director of the DVB Project office (earning himself the nickname ‘Peter 2.0′ in the process), and was treated to the latest version of the DVB standards road-map.

One of the most interesting elements to come out of our discussion concerned the fate of what used to be known as DVB-H2 – the next-generation version of the mobile/handheld broadcast standard DVB-H.

Temporarily shelved because of an intervening effort to get the satellite/terrestrial hybrid version of DVB-H (DVB-SH) underway (its first European implementation will be on the Solaris Mobile venture (see previous post), it is now back on the books again – under the working title of DVB-NGH (for ‘Next Generation Handheld).

Asked whether DVB-T2 – which has always encompassed advanced mobile broadcast capabilities as well as high-capacity fixed HDTV ones – mightn’t itself play the role of a DVB-H substitute, Siefert conceded that “maybe [DVB-NGH] is only DVB-T2. The elements of DVB-T2 are a good candidate.”

On the face of it, this might make good sense: operators in some countries are already looking upon robust profiles of DVB-T as a potential substitute for DVB-H, simply because such implementations re-use a pre-existing transmitter network.

Equally likely, perhaps, would be DVB-T2 with ‘add-ons’ – for instance, DVB-NGH could contain DVB-T2 plus LGE (4G) elements – or, indeed, it could end up as something entirely separate from DVB-T2, Siebert said.

In any event, the next DVB Technical Module meeting is expected to give the go-ahead to a new technical group which will decide what NGH will be based on.

At that same meeting, a study group will be reporting back on current industry 3D developments (very much the theme of this year’s IBC show) with a view to a decision being reached about what DVB’s role should be in the 3D standardisation process, if any. Siebert suggested DVB come contribute elements to do with service information and transport protocols.

Siebert said there was also an ongoing discussion going on between the HBBTV backers (see previous story) and DVB as to “whether DVB should play a more active role” in the hybrid DVB standardisation space, perhaps acting as an umbrella group for various industry initiatives.

Amongst other recent developments, nine European operators, including the likes of Kabel Deutschland, Kabel Baden Wittenberg, Ono and Com Hem, have now committed themselves to the next-generation version of DVB’s cable standard, DVB-C2. Siebert commented that in Germany in particular, cable operators were running out of capacity, so they required the extra capacity DVB-C2 could offer. As an example, he pointed to the fact that Kabel Deutchsland’s RFPs now contained questions about whether set-top box manufacturers were able to support DVB-C2.

The first DVB-C2 prototypes are due to be shown at the Anga Cable show in Germany next year, and IBC 2010 would certainly feature the technology, Siebert said.

IBC Report – Civolution water-marking technology poised for Q1 2010 rollout with major US pay-TV operator

Posted by Barry Flynn on September 12, 2009 No comments

The first large-scale deployment of watermarking technology in the pay-TV world should take place in the US in Q1 next year, Connected TV has learned.

Watermarking is a technique which embeds invisible identifiers into broadcast and other content, which can survive multiple transmission, compression and copying stages, in order to identify the sources of pirated material. Each device in the pre-production, production and transmission chain, all the way down to individual set-top boxes, can be given a unique code to pinpoint where the ‘leak’ has taken place.

Speaking at IBC, Alex Terpstra, CEO of Philips watermarking spin-off Civolution, declined to name the US operator in question, but said the Civolution solution it would be supplying is a hybrid one, integrating the technology at the encoder end and the set-top box. This means that as well as identifying piracy taking place at the headend, any set-top box used to illegally re-distribute protected material  can be precisely identified.

“There will be deployments in the field, we hope, in Q1 in North America,” he said. “I believe it is a break-through in the development of this industry.” The water-marking technology will be targeted at  protecting HDTV content.

Previously, except for a few small-scale IPTV deployments where watermarking is integrated into the DRM system , such content identification technologies have been confined to the pre-release market.

Examples include protecting preview copies of films given limited distribution before events such as the Oscars or the Cannes Film Festival, or content aimed at in-hotel distribution (where premium movies are made available before standard pay-per-view and pay-TV release windows).

Terprstra said the fact that the technology was now mature would permit new business models: for example, consumers might be happy to pay a premium to watch a movie at home in VOD mode while (or even before) it was being shown in the cinema. Previously, the studios might have been reluctant to allow this to happen without some sort of guarantee that piracy risks were being addressed.

At IBC, Civolution also announced that Taiwanese company MStar Semiconductor had become the first chipset maker to integrate NexGuard – Civolution’s core watermarking technology – in hardware, as part of its MSD3A11 chipset.

IBC Report – HBBTV set for pre-Christmas German retail launch using Humax and Kaon boxes

Posted by Barry Flynn on September 11, 2009 1 comment

Hybrid Broadcast Broadband TV (HBBTV) – a European hybrid DVB/IP platform backed by the European Broadcasting Union (EBU) – is due to be implemented in Germany in time for Christmas this year, using retail set-top boxes manufactured by Humax and Kaon. Launches will then follow in Q1 2010 in Austria and Switzerland.

Richard Baker, executive vice president of sales and marketing at ANT, a TV software solutions provider, laid out the schedule for the implementation of the new specification during a demonstration of the system to Connected TV this morning on the EBU stand. This used broadcast HD content from the German free-to-air satellite platform and a 2MBit/s ADSL link, running on a Kaon receiver.

The system was first demonstrated by public broadcaster ARD in association with the Institut für Rundfunktechnik (IRT) at the IFA show in Berlin a week ago. ANT’s role in the demonstration is the contribution of its Galio Suite, which now contains extensions which make it the first platform to implement the full HBBTV specification.

The three HBBTV use-cases shown at IBC were:

1) A combination of Teletext (written in HTML, CSS and Javascript) and HD broadcast content

2) Broadcast applications which can invoke additional material associated with a channel (i.e. calling up a new streamed OTT video)

3) Access to web services and third party content

In order to access such applications, the remote control used includes an extra Web TV button in addition to the standard coloured ones. Interestingly, the same content can be arrived at through use-cases 2) and 3). In the example Connected TV was shown, the red button could be used within a live broadcast to call up a menu from which a live video stream could be ordered (in this case a trailer for some ARD content), using HTTPS over the broadband connection.

Using the red button to access a Web-based entertainment portal, however, gave access to a separate list of streamable OTT content which included the same ARD trailer as mentioned above.

Asked if British players were interested in merging their rival proposals (namely the BBC/ITV/BT hybrid platform Canvas and the DTG’s D-Book 6/7) with HBBTV, Baker was diplomatic, saying only that ANT and its partners had entertained “an open dialogue with the BBC [about Canvas]. If we have the opportunity to support the desires of the BBC, we’d be very happy about that,” he said.

Farncombe: Pay-TV shift to two-way networks will mean move away from smartcard-based conditional access systems

Posted by Barry Flynn on May 21, 2009 No comments

Farncombe Consulting Group, which hosts this blog, has just published a new White Paper on how the Digital TV Conditional Access sector will be affected by the shift towards broadband-enabled pay-TV networks.

Written by Farncombe’s own highly-experienced group of in-house video security experts, the White Paper assesses the pros and cons of using smartcard-based and cardless systems in different types of pay-TV set-up, ranging from traditional one-way broadcast TV operations to broadband-enabled two-way IP and connected home networks.

The paper concludes that while smartcards continue to remain the solution of choice for protecting one-way systems, cardless-based solutions are preferable for protecting video content in IPTV, ‘over-the-top’ and home networking contexts.

For one-way networks migrating to broadband connectivity, meanwhile, both types of system have their advantages, depending largely on the availability, reliability and quality of the broadband network.

The White Paper’s authors go on to suggest that since the traditional one-way pay-TV world is slowly but surely changing into a two-way one, it is likely that there will be a gradual shift away from smartcard-based systems in favour of cardless ones – led by the digital cable sector.

The trick-mode trigger: a new paradigm for TV advertising in an on-demand world?

Posted by Barry Flynn on April 1, 2009 2 comments

As the traditional TV world migrates to an on-demand environment (‘over-the-top’ or otherwise), the evidence so far has been that where viewers are given the opportunity to, they will generally fast-forward through the ad breaks.

Various strategems have been adopted by broadcasters and advertisers to get round consumer resistance to interruptive advertising, generally involving some sort of implied bargain. For instance, the benefit of being able to make up for having missed a popular programme by viewing it in ‘catch-up’ mode is commonly set against the fact that the ads in the catch-up stream can’t be ‘zapped’. Similarly, if you want to watch an on-demand movie without any commercial breaks interrupting the action, it’s often impossible to skip the ‘pre-roll’ ad welded onto the front of it.

Well, on the evidence of three separate exhibitors at last week’s IPTV World Forum, a new paradigm is evolving. It hasn’t got a name, yet, so let’s invent one: ‘trick-mode triggers’ (you heard it here first).

The idea is to exploit the fact that on-demand viewing allows viewers to interrupt their own viewing by using VCR-like ‘trick modes’ such as pause, rewind and (yes) fast-forward – the very feature causing the zapping issue in the first place.

Connected TV has already mentioned the use of the ‘pause’ function in ANT’s Amazon application, which triggers a window showing ‘contextual’ DVDs or books available to purchase at the Amazon store. However, NDS – the private technology firm owned by the Permira Funds and News Corporation – also featured it when demonstrating the latest version of its Infinite TV technology, which Connected TV reviewed after its first showing at last year’s IBC trade-fair in Amsterdam.

Geoff Todd, NDS’s director of sales and new business initiatives, referred to it as ‘on-pause’ advertising. In the example he demonstrated, pressing ‘pause’ during the replay of a cookery programme created a Flash-based wrapper around the video advertising a relevant ingredient. In fact, this type of trick-mode related feature has been implicit in Infinite TV’s targeted advertising platform from inception, although the capability wasn’t emphasised at IBC.

The platform allows the effectiveness of different types of targeted ads (e.g. ‘pre-roll’ versus ‘on-pause’) to be compared, and their subsequent application refined. “[Infinite TV tells you] which kinds of ads have been consumed,” said Todd. “If trick-mode works better, you can pull the pre-roll or mid-roll ad.”

The third example at the show came from set-top box manufacturer ADB, which was showing Stream Group’s Solocoo online TV portal being accessed from one of its hybrid DTT-IP hybrid models.

In the demonstration shown, the trigger wasn’t the result of trick-mode use, but instead arose when the viewer decided to use the familiar left-and-right arrows on the remote control to check what was currently playing on adjacent channels, using the mini-EPG at the bottom of the screen display. At this point, the mini-EPG displayed a YouTube icon, which when the red button was pressed, offered a choice of relevant YouTube video-clips to play back. The relevant factor, however, is that the call-to-action was displayed when the viewer chose to interrupt their own viewing.

As we have noted here before, interruptive advertising may be something of an aberration – one reason viewers dispense with it when they can. But placing advertising or other calls-to-action in the breaks viewers create for themselves as part of their on-demand viewing experience could well prove to be much more acceptable – particularly when the trigger invokes contextual promotional material.
