We are the technical design body responsible for much of the BBC’s capability in supplying digital television services to the public: we make sure that all of the elements of our services function properly. As part of this work we’ve been developing a number of projects.
Based on our experience in devising and building the BBC’s original electronic programme guide (EPG) system, we now supply the necessary metadata systems expertise to ensure that the architecture works seamlessly and faultlessly from end to end. We are also investigating the use of standardised interfaces for exchanging navigational metadata between internal BBC systems and with our external partners.
The section is currently heavily engaged in the deployment of a number of key infrastructure projects bringing major transformation to the way in which our audiences receive television and radio. With Digital Switch Over, the nationwide analogue television transmitter network is being decommissioned and replaced with the extended and enhanced digital terrestrial network, upon which the Freeview service operates. At the same time as this massive change, the more advanced digital transmission system, DVB-T2 is being introduced, upon which Freeview HD will be available. The DDSD is responsible for much of the technical leadership in both these efforts.
Because of the operational nature of these current projects, and the need to maintain focus entirely on the deployment of systems in critical time frames, the DDSD section will not be able to detail its work in this public forum until a later date.
An important part of our work also involves us in access services, particularly for the hard of hearing and for blind and partially sighted people.
The work of the Distribution Digital Service Development group could not possibly be carried out in isolation. Listed are some of the partners who have helped make this work possible.
