Abstract

Entropy coding is a fundamental stage in all video compression algorithms in terms of compression efficiency and error resilience. In this paper we propose and optimize a digital signal processor (DSP)-based implementation of the CAVLC tools for the H.264 Baseline encoder. As result, we have been able to generate the bit stream and supply bit rate result: the LETI encoder is able to achieve high compression performance when proposing interesting video quality.
