Abstract
In the speckled broadcasting of HDTV and SDTV, an encoding transmitting apparatus and a decoding receiving apparatus can perform a parallel multichannel transmission and reception of SDTV with a simple construction. When an HDTV video signal is encoded and decoded, each of the transmission buffer and the reception buffer is used as a single buffer. On the other hand, when a plurality of SDTV video signals are encoded and decoded, the transmission buffer and the reception buffer are divided into the number of SDTV video signals to use them as a plurality of divided transmission buffers and a plurality of divided reception buffers, so as to perform a encoding and decoding processing.
