Media Coding Standards and Applications
Versatile Video Coding Technology and Applications
Television is the most engaging source of information and entertainment. Online services allow TV content and movies to be streamed instantly or downloaded on demand, and has opened up new ways for discovering, sharing, and consuming TV content anywhere, anytime, and on any device. Conversely, it takes nothing more than a smartphone and a YouTube channel to become a global broadcaster and producer of live events. Because improvements in video compression require additional tools and options, each generation of video codecs has a new syntax defining a bitstream so newer codecs are typically not backward compatible with older generation decoders. State-of-the-art standards such as Versatile Video Coding (VVC) and AOM Video 1 (AV1) will bring even greater efficiencies using highly complex tools. These tools are described in this course, which contains over 300 informative slides. Optimizing the efficiency of video coding requires a painstaking effort and a systematic approach in analyzing the coding performance using a wide variety of video content and coding parameters. Factors such as resolution, color/brightness volume, frame rate, and amount of information loss in video coding all impact the visual quality. This course is packed with many numeric examples to illustrate the impact and tradeoffs when combining coding parameters as well as effective tips in coding implementation.

H.264/AVC Video Coding
This course covers several important features of H.264/MPEG-4 AVC video coding standard. H.264 currently dominates web, mobile, and connected TV sectors. Virtually all new smartphones and tablets support H.264 using the MP4 container, including Apple, Android, and Windows Mobile. H.264 is also a key video format for HTML5. H.264 overcomes many limitations of motion estimation in H.262/MPEG-2 with improved interprediction via fine-grained motion estimation, multiple reference pictures, unrestricted motion search, and motion vector prediction. Additionally, H.264 offers improved intracoding in the spatial domain using a context-sensitive deblocking filter and many techniques for mitigating errors, packet losses, and bandwidth variability, such as the use of scalable bitstreams (corresponding to different quantization levels) and slice coding (with no possibility of spatial error propagation from one slice to any other slice within the video picture). The improved coding efficiency and the new error resilient features make this standard a perfect candidate for video streaming, broadcasting, and conferencing over a variety of fixed and mobile networks.

H.265/HEVC Video Coding
The emergence of UHD video services has created a need for coding efficiencies superior to H.264/AVC. The ubiquity of HD-capable mobile devices has also increased the demand for high quality video delivery. With H.265/HEVC, online video services are revolutionized by efficient and scalable delivery of digital content to heterogeneous home and enterprise networks, and user devices. Two key differences between H.264 and H.265 include increased modes for intraprediction and adaptive partitioning for interprediction. H.265 specifies three different units. The coding unit defines a region in the video picture that shares the same intra or interprediction mode. The prediction and transform units define the regions sharing the same prediction and transform information respectively. The coding and transform units are specified using different quadtrees, which can be flexibly pruned to smaller units to match the characteristics of the video content. The decoding complexity of H.265 is not significantly greater than H.264. 720p videos can be decoded on H.265-equipped mobile devices without significant battery drain.
