Signaling change in output layer sets

A method for video decoding, comprising:

• receiving a bitstream comprising a video parameter set and bits representing a current picture;
• parsing at least a portion of a slice header of the current picture;
• performing a first determination, based on one or more syntax elements in the video parameter set, whether a removal operation from a decoded picture buffer (DPB) is to be performed on a per-picture basis or per-access unit (AU) basis, wherein an access unit comprises at least a base layer and an enhanced layer, and each layer represents a picture;
• performing a second determination, separate from the first determination, based on one or more syntax elements in the video parameter set, whether a picture output operation from the DPB is to be performed on a per-picture basis or per-AU basis;
• performing the removal operation from the DPB in accordance with the first determination whether the removal operation is to be performed on a per-picture basis or per-AU basis;
• performing the picture output operation from the DPB in accordance with the second determination whether the picture output operation is to be performed on a per-picture basis or per-AU basis;
• performing a decoding and storing of a current decoded picture in the DPB.

An electronic device configured for video coding, comprising:

• a processor;
• and
• memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
• receive a bitstream comprising a video parameter set and bits representing a current picture,
• parse at least a portion of a slice header of the current picture,
• performing a first determination, based on one or more syntax elements in the video parameter set, whether a removal operation from a decoded picture buffer (DPB) is to be performed on a per-picture basis or per-access unit (AU) basis, wherein an access unit comprises at least a base layer and an enhanced layer, and each layer represents a picture,
• perform a second determination, separate from the first determination, based on the one or more syntax elements in the video parameter set, whether a picture output operation from the DPB is to be performed on a per-picture basis or per-AU basis,
• perform the removal operation from the DPB in accordance with the first determination whether the removal operation is to be performed on a per-picture basis or per-AU basis,
• perform the picture output operation from the DPB in accordance with the second determination whether the picture output operation is to be performed on a per-picture basis or per-AU basis, and
• perform a decoding and storing of a current decoded picture in the DPB.
