Abstract
A method is provided that includes determining a target picture virtual memory access (VMA) bandwidth rate, wherein the target picture VMA bandwidth rate indicates a maximum VMA bandwidth rate for motion compensation of a picture, and verifying the target picture VMA bandwidth rate for a compressed video bit stream.
Claims15
A system comprising:
- a processor configured to receive a video sequence and transform the video sequence into coding units;
- and
- an encoder configured to:
- encode the coding units into a compressed video stream;
- determine a target memory bandwidth for the compressed video stream that is less than a maximum bandwidth;
- signal the target memory bandwidth in the compressed video stream;
- and
- impose the target memory bandwidth on the compressed video stream.

A method comprising:
- transforming, by a processor, a video sequence into coding units;
- encode, by an encoder coupled to the processor, the coding units into a compressed video stream;
- determining, by the encoder, a target memory bandwidth for the compressed video stream that is less than a maximum bandwidth;
- signaling, by the encoder, the target memory bandwidth in the compressed video stream;
- and
- verifying, by the encoder, a bandwidth of the compressed video stream does not exceed the target memory bandwidth.
