  • System for coding video signal in block unit
    Patent number: 4679081
    Abstract: A system for coding video signals e.g. television signals in block units is disclosed. The coding system comprises a synchronization detector for detecting a frame synchronization from the video signal, and a block former operative to divide the video signal in block units per a predetermined number of lines by using a picture frame synchronization signal detected by the synchronization detector as a reference. When the number of lines included in a block immediately before the subsequent picture frame synchronization signal is less than the predetermined number of lines, the block former designates the block as an ineffective block.
