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.
Claims20
A method comprising:
- encoding, by a processor, a first coding unit (CU) in a picture;
- determining, by the processor, a consumed virtual memory access (VMA) bandwidth for the first CU;
- limiting, by the processor, a maximum number of reference pictures for motion estimation for a second CU in the picture based on the consumed VMA bandwidth for the first CU;
- and
- encoding, by the processor, the second CU using the limited maximum number of reference pictures for motion estimation.
2 more elements
A system comprising:
- a processor configured to:
- receive a video sequence including a picture;
- and
- transform the video sequence into coding units (CUs);
- and
- an encoder configured to:
- encode a first CU in the picture;
- determine a consumed virtual memory access (VMA) bandwidth for the first CU;
- limit a maximum number of reference pictures for motion estimation for a second CU in the picture based on the consumed VMA bandwidth for the first CU;
- and
- encode the second CU using the limited maximum number of reference pictures for motion estimation.
8 more elements
A method comprising:
- encoding, by a processor, a first largest coding unit (LCU) in a picture;
- determining, by the processor, a consumed virtual memory access (VMA) bandwidth for the first LCU;
- and
- encoding, by the processor, a second LCU in the picture without 8×8 CUs based on the consumed VMA bandwidth for the first LCU.
