Abstract
A method and apparatus for generating and transmitting bit rate conversion information to be utilized during bit rate conversion decisions and a method and apparatus for performing bit rate adaptation of media signals to use an available bandwidth of a channel, the media signals being associated with bit rate conversion information, the method for utilizing the bit rate conversion information including the steps of: receiving the media signals and the bit rate conversion information; the bit rate conversion information being indicative of a change in a bit rate of the media signals resulting from bit rate conversion; and converting the multiplexed processed media signals in response to the available bandwidth and the bit rate conversion information.
