ABSTRACT:
A block coding system wherein switching block coding integrated circuit chips changes the coding parameters by selecting the number of colors per block from the minimum of two to six or more, and selecting the block size correspondingly to maintain coding efficiency, thus to insure quality of color in video data transferred over medium to narrow-band paths. Switching integrated circuit chips in the system can set coding parameters for the acceptable degree of degradation by data compression block coding of any type of structured data, including digital television signals transferable over a data path of medium to narrow bandwidth.
