Method and apparatus to prioritize video information during coding and decoding

摘要

A method and apparatus prioritizing video information during coding and decoding. Video information is received and an element of the video information, such as a visual object, video object layer, video object plane or keyregion, is identified. A priority is assigned to the identified element and the video information is encoded into a bitstream, such as a visual bitstream encoded using the MPEG-4 standard, including an indication of the priority of the element. The priority information can then be used when decoding the bitstream to reconstruct the video information

1. A method comprising:
identifying, via a processor, a priority of a video object layer in a plurality of video object layers associated with a video object; transmitting an encoded video object in a bitstream, wherein the encoded video object comprises a three bit priority code based on the priority of the video object layer; and transmitting a video object layer identifier code in the bitstream, wherein the video object layer identifier code indicates whether the priority has been specified for the video object layer.
