Abstract
A heterogeneous multimedia stream has interleaved samples of two or more different substream types. For example, a heterogeneous video stream may have interleaved intra, predicted, and bi-directional frames. In addition to a global bit bank, a different bit bank is maintained for each different frame type. A global quantization level is selected for each frame based on the global bit bank and the bit bank for the corresponding frame type. The frames are encoded using the selected global quantization levels. In a preferred embodiment, the number of bits available for encoding frames differs based on the frame type. In addition, any unused bits from encoding the current frame are shifted from the bit bank corresponding to the current frame type to a bit bank of a different frame type.
