Abstract
The present invention discloses methods and systems of statistical video multiplexing to improve the performance of video encoding by minimizing delay while achieving high video quality. The video encoders used in the system are capable of calculating the complexity of underlying video sources and communicating the complexity to the multiplexer. Furthermore, the video encoders are capable of estimating the look-ahead complexity, i.e. the future complexity and communicating the future complexity values to the multiplexer. A processor associated with the multiplexer allocates bit rates for the video encoders according to the received complexity values and future complexity values. The bit rate information is then communicated to the video encoders. Each video encoder will then exercise its coding control parameters to regulate the resulting bit rate to be within or close to the allocated bit rate.
