Paper Abstract

The transmission of digital video signals to the end user, which is known as secondary distribution by CCITT, is one of the key point of Broadband ISDN (B-ISDN). Sufficient picture quality can be obtained at a bitrate of 17 Mbit/s (or even lower) by using a hybrid DCT scheme working on blocks of 8 pels by 8 lines of the same frame (instead of lines of the same field) associated to block matching motion estimation and compensation. The optimization of the block matching algorithm (BMA) and the adaption of the hybrid DCT scheme to blocks designed on a frame basis are presented hereafter.
