Video rate-buffer management scheme for mpeg transcoder

摘要

A video buffer rate-management system and method for a transcoder buffer is disclosed. The rate-management system includes logic circuitry for determining a bit budget for a current picture at an input to the decoder, measuring a buffer fullness of an encoder buffer when the encoder buffer receives a previous picture, and allocating a number of bits to the current picture based on the buffer fullness, such that the allocated bits of the current picture is within the bit budget.
