output system, where several HDTV streams generated by the encoder modules are
output directly in parallel or multiplexed into one transport stream (TS). We used
the multiple stream output system for SHR communication applications, because
conventional HDTV decoders can decode its output stream, whereas a one-stream
SHR output system needs dedicated SHR decoders. There is an overview of our
CODEC system in Fig. 2. The CODEC has two output modes, i.e., a multiplexing
and a non-multiplexing mode. In the non-multiplexing mode, each encoder module
outputs a constant bit rate (CBR) ES, and this is converted into CBR-TSs which are
