Abstract :
A video coding scheme based on an intra-2frame DCT (discrete cosine transform) coding is described. This scheme is intended to reduce the bit rate of the 4:2:2 component signal down to 12.5 Mb/s without relying on motion estimation and compensation. The algorithm has been successfully simulated and achieved a reasonable quality for consumer use of digital VCRs
