Abstract: 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.

The appearance of network cables comprising six twisted pairs of wires makes it possible to produce networks having higher speed capacities. The object of the invention is not to increase speeds by using additional twisted pairs but to simplify the data traveling through the network.

The parallel context modeling may be used in encoding or decoding operations.
