摘要： Methods and apparatus efficiently encode multimedia data, such as live video streams. An encoding complexity of a predetermined time interval, such as 1 second, is estimated before the actual encoding that will be used. This permits the actual encoding to be performed with an a priori estimate of complexity, permitting the bits allocated for the predetermined time interval (bit rate) to be efficiently allocated within the predetermined time interval. Moreover, the estimated complexity can be provided to a device, such as a multiplexer, which can then allocate the available bandwidth for a collection of multiplexed video channels according to the encoding complexity anticipated for those video channels, which then permits the quality of a particular channel to remain relatively constant even when the bandwidth for the collection of multiplexed video channels is relatively constant.

摘要： An apparatus and method for processing multimedia data, such as, for example, video data, audio data, or both video and audio data for encoding utilizing a determined content classification is claimed. Processing the multimedia data includes determining complexity of multimedia data, classifying the multimedia data based on the determined complexity, and, determining a bit rate for encoding the multimedia data based on its classification. The complexity can include a spatial complexity component and a temporal complexity component of the multimedia data. The multimedia data is classified using content classifications, which are based on a visual quality value for viewing multimedia data, using the spatial complexity, the temporal complexity, or both the spatial complexity and temporal complexity.
