White Paper WHP 040 Download
Major changes to the BBC's Public Service Digital Television (PSDTV) services have taken place during the last eighteen months. These have had a significant impact on the BBC's technical architecture for digital television, with infrastructure in London and national centre in Scotland, Wales and Northern Ireland requiring major change and expansion. This paper outlines the service developments and describes the architectural changes needed to support them under three main categories- statistical multiplexing, time-exclusive services, and enhanced interactive services.
