Overview of the High Efficiency Video Coding (HEVC) Standard
TL;DR: The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards-in the range of 50% bit-rate reduction for equal perceptual video quality.
Journal ArticleDOI
Intra Coding of the HEVC Standard
TL;DR: The design principles applied during the development of the new intra coding methods are discussed, the compression performance of the individual tools is analyzed, and the bitrate reduction provided by the HEVC intra coding over the H.264/advanced video coding reference is reported to be 22% on average and up to 36%.
Journal ArticleDOI
Block Partitioning Structure in the HEVC Standard
TL;DR: Technical details of the block partitioning structure of HEVC are introduced with an emphasis on the method of designing a consistent framework by combining the three different units together and experimental results are provided to justify the role of each component.

TL;DR: This paper provides a technical overview of a newly added in-loop filtering technique, sample adaptive offset (SAO), in High Efficiency Video Coding (HEVC), to reduce sample distortion by first classifying reconstructed samples into different categories, obtaining an offset for each category, and then adding the offset to each sample of the category.

Method and apparatus for encoding video, and method and apparatus for decoding video
Abstract: Disclosed are a method and a apparatus for encoding a video, and a method and apparatus for decoding a video, in which neighboring pixels used to perform intra prediction on a current block to be encoded are filtered and intra prediction is performed by using the filtered neighboring pixels.
