We very much would like to hear your ideas and comments on this issue. As you may have known, we are working the IETF specification on the RTP Payload Format for EVRC/SMV. It specifies how the EVRC/SMV payload is carried in RTP sessions, and it also registered the MIME format for the EVRC and SMV vocoders. The draft (draft-ietf-avt-evrc-smv) is currently at the final editing stage at the IETF FRC Editor's queue. There has been a file format defined in the draft-ietf-avt-evrc-smv at the MIME registration for EVRC/SMV. The file format specified there hasn't been changed much since the first version of the draft in 2000. There is a new Internet Draft, draft-garudadri-qcp-00.txt, specifies a different way of storage using the QCP file format, which has been used for QCEPL-13K and EVRC by some applications. Currently, it has been proposed to remove the file format specification in the draft-ietf-avt-evrc-smv, and to expand the draft-garudadri-qcp to be the only formal specification for the file format for EVRC/SMV. On the other hand, there are also suggestions to keep the file format at it is specified in the draft-ietf-avt-evrc-smv. We would like to hear your suggestions, and hear from you how you think would be the best way to proceed. Your comments are very much appreciated.
