Apparatus, system, and method for video encoder rate control |
摘要 |
<p>A video encoder includes a programmable rate controller. In one embodiment, the programmable rate controller includes a variable bit rate controller, a constant bit rate controller, and an arbitration logic for selecting one of the two outputs. An embodiment of a variable bit rate controller tracks long-term changes to average bit rate. An embodiment of a constant bit rate controller classifies macroblock types, determines a statistical indicator of complexity for each macroblock type, and generates a target bit rate based on estimated complexity. <IMAGE></p> |
