Hi Mark,
In ATRAC receiver side, it is required to know sampling frequency, bit-rate and channel configuration in order to switch and initialize the decoder and associated hardware for immediate starting of ATRAC3, ATRAC-X or ATRAC Advanced Lossless decoding.
We think it is the best way to signal above parameters in SDP session with media type registarion procedure.
Hi Jun. I suppose that answers my question about a recipient being able to determine those parameters from the data itself, but I'm still not clear why a parameter is marked as required when it can only have a single value. Is it perhaps because other values may be supported in the future? Some other reason? Mark.
