    摘要: A system and method for enabling the removal of decoded pictures from a decoded picture buffer as soon as the decoded pictures are no longer needed for prediction reference and future output. An indication is introduced into the bitstream as to whether a picture may be used for inter-layer prediction reference, as well as a decoded picture buffer management method which uses the indication. The present invention includes a process for marking a picture as being used for inter-layer reference or unused for inter-layer reference, a storage process of decoded pictures into the decoded picture buffer, a marking process of reference pictures, and output and removal processes of decoded pictures from the decoded picture buffer.

    摘要: In a start code based bistream structure for use in video coding, a picture header is used simultaneously with the parameter set in the start code. The picture header is present before the slice header in the same picture. As such, it is possible to allow the presence of at least one sequence parameter set or picture parameter set before the slice header. In a NAL unit parameter set bitstream structure, the picture head NAL unit is present before the slice NAL unit. In either structure, the picture header information must remain unchanged during the decoding of the entire picture, but should change more frequently between pictures as compared to the information in the picture parameter set.

    摘要: A system and method for conveying supplemental enhancement information related to different pictures in one access unit. Different pictures in one access unit may be pictures of each layer of a scalable video, pictures of each view of a multiview video, or pictures of each description in a multiple description coding (MDC) video. An indication is included in the coded bitstream indicating the pictures with which the supplemental enhancement information message is associated. During a subsequent decoding process, the device performing the decoding recognizes this information and uses it appropriately.
