Paper Abstract

The transmission of Digital High Definition Television signal over terrestrial broadcast channel imposes severe requirements on the signal. The system has to handle very large variations of Signal-to-Noise Ratio depending on the distance between transmitter and the receiver and the quality of receiving equipment e.g. antenna. It should provide the HDTV quality picture whenever possible and viewable picture in very poor conditions. One possible solution to this problem is the system providing easily retrievable standard resolution signal embedded in the HDTV signal. In this paper we consider the design of the channel coding part of the system as well as joint optimization of source and channel coding. The results of the simulations of such a system are also included.
