“…A secondary objective of this study was to judge the extent of bit errors without bit error correction (or error concealment). Other studies [11] have investigated the possibility of bit error correction, which could subsequently also be applied by us.…”

Abstract-For real-time video streaming applications it is important to preserve both privacy and delay sensitivity. To achieve, this selective encryption exploits the entropy coding stage of hybrid codecs. As streaming applications move towards mobile networks, they become vulnerable to bit errors in the wireless channel. This paper is a pioneering analysis of the relative impact of bit errors on the two H.264 codec entropy coders, CAVLC and CABAC. The joint impact of compression and encryption on objective video quality is determined in experiments, when it is found that CAVLC is much more vulnerable to bit errors compared to CABAC. This finding will guide future bit error protection schemes.
