Abstract
Ensuring integrity of a video buffer verifier (VBV) employed in MPEG-like video encoders is realized by controllably adjusting the bits being drained from a video encoder buffer (eBuff). The number of bits being drained from eBuff is adjusted through feedback to minimize the difference in the bit content of a buffer (mBuff) maintained in a bit-rate controller in the video encoder that models the buffer of a hypothetical decoder, and the bit content of that hypothetical buffer (vBuff). Specifically, this is realized by controllably inhibiting transmission of bits from eBuff during intervals that the value of a prescribed relationship is greater than a predetermined value. In one example, the prescribed relationship is dependent on an instantaneous video encoding rate, an end-to-end delay, the bit content of mBuff and the bit content of eBuff.
