Abstract
An integrative encoding system for encoding and transmitting a plurality of video signals having different resolutions that correspond to a plurality of display units. The integrative encoding system has a compression processor, an editing processor, and an integrated services digital broadcasting (ISDB) transmitter. The compression processor performs adaptive dynamic range coding (ADRC) to compress each of said plurality of video signals on a block basis by reducing the dynamic range. An adaptive decoding system receives and decodes the transmitted plurality of video signals for display by the plurality of display units.
Claims4
An integrative encoding system for encoding and transmitting a plurality of video signals having different resolutions, comprising:
- a compression processor for performing adaptive dynamic range coding (ADRC) to compress each of said plurality of video signals on a block basis by reducing the dynamic range;
- an editing processor for editing the compressed plurality of video signals;
- a sync block processor for forming a bit stream from the edited and compressed plurality of video signals and a synchronous signal;
- and
- an integrated services digital broadcasting (ISDB) transmitter having:
- a time code generator for generating a time code synchronized to said synchronous signal;
- an additive information generator for generating additive information in synch with said synchronous signal;
- and
- a multiplexer for multiplexing said bit stream, said additive information, and said time code into ISDB data for transmission.
