D-Book goes connected

The UK Digital TV Group (DTG) recently announced the publication of version 7 of the D-Book, the interoperability specification for digital terrestrial TV in the UK. This is a major update for the D-Book, bringing connected TV to the forefront and aligning the UK’s work in this area with activities in other industry bodies.

The DTG has taken the approach of building on existing standards, but extending them where necessary to meet UK-specific needs (such as interoperability with MHEG) or to add features that were not stable at the time HbbTV was published. Although based on HbbTV, D-Book 7 adds support for additional parts of the OIPF specifications, for advanced graphics capabilities defined in HTML 5 and CSS 3, and for smooth media streaming over IP.

ANT has been heavily involved in this work , and we see this as a huge step for connected TV in the UK. This not only gives manufacturers and application developers a common standard to work to – it gives them a standard that’s aligned with other HbbTV deployments in Europe. D-Book 7 goes beyond HbbTV in terms of features and functions, enabling it to offer more advanced services, but also remains compatible with basic HbbTV applications.

While the UK’s early adoption of digital TV put it ahead of many countries, the choice of MHEG-5 did leave the UK as a “digital island”. D-Book 7 offers the UK TV industry a chance to resolve that and gain from further economies of scale, while retaining its leading position in the development and deployment of interactive TV services.

W3C Web and TV Workshop – Connecting TV and the Web

While many TVs in the market today are making use of web technologies to provide “connected TV” services, historically there’s been very little communication between the major players in the TV and Web worlds. Last week I spent some time at the W3C’s Web and TV Workshop in Berlin, which is one of a series of workshops organised by the W3C to try to improve this communication. I was presenting on behalf of the UK DTG, but there were also presentations that discussed the work of OIPF, HbbTV and other TV standards bodies.

While there will always be differences between the two industries (the philosophy around software upgrades, requirements on the stability of specifications, and the attitude to patent licensing, for example), there is scope for collaboration and these workshops have been a good place for starting the discussion that’s needed. Both sides recognise the importance of this kind of discussion: as more and more content providers deliver media to TVs, PCs, tablets and phones, this kind of co-operation is going to become crucial over the coming year.

This co-operation may involve bringing existing work from the TV world in to Web standards, or making sure that work underway in the W3C is suitable for use by TV services as well as services on PCs and mobiles. It will most likely be a bit of both, since both sides have a lot to offer. Both sides will benefit most, if we can avoid trying to re-invent the wheel, and hopefully these workshops and their follow-up activities will help keep that to a minimum.
