High Efficiency Video Coding (HEVC), also known as H.265, is a video compression standard that was developed to provide better compression and improved video quality compared to its predecessor, H.264/AVC. HEVC is designed to compress video data more efficiently, allowing for higher compression ratios and smaller file sizes, while maintaining similar levels of video quality. This makes HEVC particularly useful for applications such as streaming high-definition video, ultra high-definition (4K/8K) video content, and virtual and augmented reality.
HEVC uses advanced video coding techniques, such as improved motion compensation, sample adaptive offset (SAO) filtering, and flexible macroblock ordering (FMO), to reduce the amount of data needed to represent a video sequence. Additionally, HEVC introduces new coding tools, such as tiles, wavefront parallel processing, and scalable coding, that enable more efficient encoding and decoding of video content.
Overall, HEVC provides significant improvements over previous video coding standards, including better compression efficiency, improved video quality, and increased versatility and scalability. This makes it a key technology for the future of video compression and delivery.
