AVCC (Advanced Video Coding Configuration) sequence header, also known as the SVC ( Scalable Video Coding) sequence header, is a part of the High Efficiency Video Coding (HEVC) standard. It specifically relates to the Scalable Video Coding extension, which allows for multiple quality layers within a single video stream, enabling adaptive streaming and better bandwidth utilization.
The sequence header in an AVCC structure contains information about the coding parameters for each scalability level. This includes parameters like picture order count (POC), temporal scalability levels, spatial scalability (layered pictures), and other metadata necessary for decoding the video content efficiently. It helps decoders navigate through the different layers and choose the appropriate one based on the viewer's available bandwidth or display capabilities.
