Abstract:
A method for transmitting variable bit rate information in a communication system, wherein said variable bit rate information is transmitted in frames having a fixed length comprising a variable-length payload data field and a variable-length frame type indicator field, said method comprising the steps of:providing at least two different coding rates for processing said variable bit rate information; coding said variable bit rate information at a rate based on a selected one of said at least two different coding rates; including a frame type indicator with said coded information in a frame, said frame type indicator being selected from at least two frame type indicators depending upon said selected one of said at least two different coding rates, wherein said at least two frame type indicators have a different bit length inversely-proportional to said coding rate; and transmitting said frame including said frame type indicator in said variable-length frame type indicator field and said coded information in said variable-length payload data field.
