Titel
Flexible bit rate coding for satellite transmission of HDTV
Abstract
Describes coding schemes for HDTV with flexible bit rates between 34 and 70 Mbit/s. DCT and subband schemes have been investigated and compared and finally a DCT scheme based on a modified ETSI-codec (CCIR-Rec. 723) has been selected for hardware implementation balancing coding performance, hardware complexity and time constraints. This codec is part of a satellite transmission system for HDTV contribution, which adapts its user bit rate automatically to the actual transmission conditions.
