Bit rate control over groups of frames

Systems and methods are described for processing data from a sequential series of groups of frames to achieve a target average processing bit rate for a particular group of frames in the series. In an example, a look-ahead buffer circuit can be populated with a number of frames from a particular gro...

Zusammenfassung:	Systems and methods are described for processing data from a sequential series of groups of frames to achieve a target average processing bit rate for a particular group of frames in the series. In an example, a look-ahead buffer circuit can be populated with a number of frames from a particular group of frames, and a bit allocation can be determined for a frame in the look-ahead buffer circuit using bit request information about all of the frames in the buffer. The look-ahead buffer circuit can be populated with streaming frame information in a first-in-first-out manner, and bit allocation processing can be performed for each frame, in a particular group of frames, based on a frame position in the look-ahead buffer circuit and further based on bit requests associated with other frames in the look-ahead buffer circuit.
