    Abstract

    The amount of video data stored on local devices or transmitted over the networks is permanently increased. The emerging of a more efficient next generation video coding standard is of a high demand at the moment. There seem to be two main contenders for the posi- tion of the next state-of-the-art video compression standard: JCT-VC H.265/HEVC and Google VP9. The announced aim of HEVC is to achieve twice more efficient compression compared to H.264/AVC, and VP9 was developed to get half the bit-rate of VP8 with royalty-free video codec. Intra compression is one of the main features that determines the compression efficiency of the whole codec. In this paper we get into detailed overview of intra compression data- ow in HEVC and VP9. We describe common and unique stages of both standards. Then we carry out experiments with JCT-VC HM and WebM VP9 encoders on intra compression efficiency. We also turn some of the HEVC features off to get its data ow as close to VP9 as possible. Finally we get into discussion of the efficiency of both codecs, the corresponding standards and their intra compression algorithms.
