Bit-rate control in a multimedia device

摘要

A multimedia terminal comprising: a first encoder (100) for producing a first bit-stream (107) of a first media type and having a first bit-rate; a second encoder (110) for producing a second bit-stream (112) of a second media type and having a second bit-rate; a multiplexer (120) for combining at least the first (106) and the second (112) bit-streams into a third bit-stream (123). The terminal comprises an input element (130) for receiving preference information (131) coupled to the first encoder (100) and the second encoder (110), said preference information (131) indicating a preferred combination of the first and the second media types in the third bit-stream and affecting the first and the second bit-rates. Thus, the transmission capacity is utilised in a more optimised manner and the proportions of different media types are better adjusted to the purpose of the information transfer.
