Title
Fast channel switching for single-loop scalable HEVC.
Abstract
In an IPTV environment, different techniques exist to provide faster random access or equivalently, a faster channel switching experience, but none of them provide backward compatibility and limited overhead at the same time. In this paper, a technique is proposed to increase the random access frequency for the High Efficiency Video Coding (HEVC) standard by using a single-loop scalable version of it. This is achieved by encoding an enhancement layer with a higher frequency of random access points compared to the base layer. With this scalable configuration, a backward compatible base stream remains present. The proposed technique requires 12.4% less bitrate compared to sending the fast and slow switching streams in a non-scalable way. Compared to the almost standardized multi-loop scalable extension of HEVC, 5.5% less bitrate is needed on the core of the IPTV network and 12.5% less bitrate on the access network during steady state conditions. Moreover, the multi-loop scalable extension does not provide backward compatibility with legacy HEVC decoders.
