Abstract
A video encoder unit receives a video signal to encode along with auxiliary services such as audio streams and/or data streams. While the auxiliary streams are allotted a fixed bandwidth, the video encoder determines a required video bandwidth, which must be allocated in response to the request by a central allocator. Where economies are made in the auxiliary services for example by transmitting stereo audio instead of surround sound for example, the bandwidth requested from the central allocator is inflated by an amount corresponding to a proportion of the economized bandwidth. The extra bandwidth allocated on this basis may then be used for improving the quality of video encoding, and/or reserved for the transmission of asynchronous data.
