ABSTRACT:
An apparatus for the transmission and reception of block coded discrete cosine transformed digital video signal having coefficients representing a DC component and a plurality of AC components of various importance. A means responsive to the digital signal separates and stores like components of the transformed digital signal. The like components are assembled into segments which define a portion of a picture. Addresses of the segments are generated and added thereto. The segments are modulated for transmission by a modulating means. Upon reception the modulated segments are demodulated by a demodulating means. The like components of segments are stored responsive to the addresses. A means, coupled to the storing means and responsive to the addresses, reconstructs from the like components, the block coded discrete cosine transformed digital video signal.
