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. In a first embodiment, 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. In another embodiment,the compression processor performs hierarchical encoding on the plurality of video signals by selectively replacing pixels of a higher resolution level with pixels from a lower resolution level calculated by combining pixels from said higher resolution level; thereby encoding a hierarchy of resolution levels within the plurality of video signals without increasing the amount of data. An adaptive decoding system receives and decodes the transmitted plurality of video signals for display by the plurality of display units.
