Title:
Decoding picture buffer processing for the random access point picture in a video sequence
Document Type and Number:
Japanese Patent JP6234997
Kind Code:
B2
Abstract:
Systems, methods, and devices for processing video data are disclosed. Some examples determine that a current picture is a broken-link access (BLA) picture. These examples may also mark a reference picture in a picture storage buffer as unused for reference. In some examples, this may be done prior to decoding the BLA picture.
