Solutions for DVB-T Systems

The digitisation of terrestrial transmission has arrived. Throughout the world pilot schemes and commercial preparations have started. Digital transmission enables many more programmes to be broadcasted in the same bandwidth, so that there can be a substantial increase in revenues for network providers and a considerable reduction in costs for existing service providers. In addition the prospect of digital transmission brings crystal clear pictures and sound to the consumer. As an added bonus, the digital era opens the gateway to compelling additional services such as electronic programme guides, pay TV, data broadcasting (e.g. transportation of high-speed IP data) and enhanced broadcasting (e.g. home shopping, quiz). — This contribution addresses several key issues that play a key role when constructing digital terrestrial systems based on the DVB-T standard. Various solutions will be presented that enable broadcasters and network operators to achieve their business goals. The following topics will be addressed: • video encoding in conjunction with statistical multiplexing; • primary distribution; • remultiplexing; • splicing; • (joint) bit rate transcoding; • logo insertion; • network management; • SI (re-)generation and distribution; • conditional access and DVB simulcrypt; • enhanced and data broadcasting.
