Method and system for generating, transmitting and utilizing bit rate conversion information
First Claim
1. In a distribution center configured to transmit a plurality of media streams, a method for generating and transmitting bit rate conversion information, the method comprising:
- receiving at least one media stream, the at least one media stream to be transmitted over a communication channel;
applying at least one bit rate conversion scheme on the at least one media stream;
analyzing the results of the appliance of the at least one bit rate conversion scheme to provide bit rate conversion information;
wherein the steps of applying and analyzing are repeated to produce bit rate conversion information indicative of results of an appliance of a sequence of bit rate conversion schemes on the at least one media stream;
wherein the method further comprisestransmitting the bit rate conversion information and the at least one media stream until there is a need to convert the bit rate of a media stream out of the at least one media stream by applying a first bit rate conversion scheme out of the sequence of bit rate conversion schemes; and
applying the first bit rate conversion scheme by a receiver, and discarding bit rate conversion information relating to a first bit rate conversion information to provide modified bit rate conversion information.

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.
