Abstract
The H.264/Advanced Video Coding (AVC) standard has been widely used in the last 10 years, and this has led to a large amount of legacy video being currently encoded in this format. However, the new High Efficiency Video Coding (HEVC) standard has recently been developed and it is thought that it will dominate the market in the next few years. These two facts make an efficient transcoding system between H.264/AVC and HEVC necessary. Moreover, it should be taken into account that intra sequences are commonly used in certain scenarios, such as video editing and post-production, making a migration of these intra contents from H.264/AVC to HEVC necessary. This paper proposes a fast intra H.264/AVC to HEVC transcoding system that is based on Bayesian classifiers and which outperforms other state-of-the-art algorithms, achieving a good complexity reduction with a negligible bit rate increase.
