Real time TV image compression using motion-compensated frame prediction and interpolation

As part of the SPECTRE research programme, National Transcommunications is studying the digital coding of broadcast resolution television. Much activity is focusing on target bit rates around 12 Mbits/sec for conventional resolution, and 20-30 Mbits/sec for HDTV. To achieve these levels of data compression, very sophisticated techniques need to be used to exploit temporal and spatial redundancy in the source image. The authors describe a two stage coding techniques.<
