Abstract

In one example a video decoder is configured to store an adaptation parameter set (APS) data structure in a buffer of a coding device wherein the APS data structure includes signaling data applicable to one or more slices of video data decode at least one of the slices based on the signaling data of the APS data structure after decoding the slice determine that the APS data structure can be removed from the buffer remove the APS data structure from the buffer based on the determination and decode one or more additional slices of the video data after removing the APS data structure from the buffer.
