Abstract

A low cost and low-bit rate video codec for the transmission of traffic images using 64 kbit/s channels is presented. To minimize hardware complexity and data volume, a predictive coding structure with conditional replenishment has been selected. Input pictures are tessellated into 2-D blocks, compared with a reference picture, and only those blocks with significant differences are transmitted.
