H.264 AVC/SVC and H.265/HEVC

Video compression refers to reducing the quantity of data used to represent digital video images, and is a combination of spatial image compression and temporal motion compensation. H.264.AVC is the latest video compression standard developed by the ITU-T with ISO/IEC. H.264 is most popular for its use on Blue-ray disc and HD DVD. High-performance Video Coding(HVC) is a proposed video compression standard, a successor to H.264/AVC. HVC targets next-generation content capture system which feature progressive scanned frame rates and increased display resolutions up to 1080p and UHD, as well as improved noise level, color gamut and dynamic range. It aims to substantially improve coding efficiency, that is decrease computational complexity compared to AVC High Profile while having the same image quality and reduced bitrate requirements, especially at high resolutions. Depending on the application requirements, HVC should be able to trade off computational complexity, compression rate and processing delay time.

3-Dimensional Video Coding

There is a common characteristic among the applications of 3-Dimensional video. That is a vast amount of input data to be compressed and transmitted to the users. Thus, efficient 3D scene representation and 3D content compression technologies are essential parts of the 3DV system. In this point of view, Multi-view Video plus Depth (MVD) is a popular format for the 3DV applications because of its suitability for rendering and compression. Recently, the Moving Picture Experts Group (MPEG) released a standard for efficient compression and delivery of such data, and the standardization for multi-view color video coding is already completed as Multi-view Video Coding (MVC). However, the standardization for the depth video coding has not been conducted yet. Therefore, efficient depth video coding technologies are strongly required for the complete 3DV system. Now our research group is focusing on the efficient technologies for the depth data compression.
