发明名称 METHOD AND APPARATUS FOR SELECTION OF BIT BUDGET ADJUSTMENT IN DUAL PASS ENCODING
摘要 The present invention discloses a system (100) and method for adaptive adjustment of bit budget based on the content of the input image sequence. In one embodiment, two encoders (110, 120) are employed in a dual pass encoding system. A first encoder (110) receives the input image sequence and encodes each frame of the image sequence using a standard or any predefined encoding algorithms. Specifically, by encoding the image sequence using the first encoder (110), the first encoder (110) is able to assess the complexity of each picture in the image sequence, e.g., by measuring the number of bits needed to encode each picture. This complexity information serves as look-ahead information for a second encoder (120).
