AI

This paper discusses the advancements in video compression technology, focusing on the High Efficiency Video Coding (HEVC) standard, also known as H.265, which offers significantly improved compression efficiency compared to its predecessor, H.264. Approved by MPEG and ITU, HEVC is designed to support higher-resolution video streams and provides around 50% bandwidth savings, enabling greater content delivery over the same network infrastructure. The collaborative efforts for the standardization involved various stakeholders, including manufacturers, operators, and researchers, highlighting the ongoing evolution in multimedia processing and coding.

What compression efficiency improvements does HEVC provide over H.264?add

HEVC offers approximately 50% higher compression efficiency than H.264, enabling double the transmitted video capacity on networks.

How has HEVC been optimized for parallel processing in video encoding?add

HEVC includes tools like Tiles and Wavefront Parallel Processing (WPP) to facilitate independent processing of coding tree units, enhancing multi-core processor utilization.

What technologies underlie HEVC's ability to handle high-resolution video efficiently?add

HEVC employs hybrid block-based coding with variable coding tree unit sizes up to 64 × 64 pixels, optimizing compression for high-resolution content.

What key features differentiate HEVC from prior video compression standards?add

HEVC supports up to 33 angular prediction modes and a single-context adaptive binary arithmetic coder, improving both coding efficiency and encoding flexibility.

What future enhancements are planned for HEVC beyond its initial version?add

Planned extensions for HEVC include support for 3D video, scalable encoding for varied network conditions, and improvements for range extensions and color formats.
