ABSTRACT:
A highly efficient coding apparatus is configured to divide a digital picture signal into picture blocks and, based on a signal from a coding circuit for performing variable-length coding of each picture block, generate an output signal in the form of serial sync blocks. By inserting the most significant bit of a coded output signal for each picture element in a predetermined position of each sync block, a reproduced picture is obtained in a picture search mode in which a magnetic head scans a video tape across a plurality of tracks.
