COMMENT:
----------------------------------------------------------------------

Thanks for addressing the discusses and comments.

I leave this comment, as something that could have been more explicit about
decoding, however one skilled in the art will figure it out.

        A. Section 3.3:
           TSVCIS coder frames in a single RTP packet MAY be of different coder
   bitrates.  With the exception for the variable length TSVCIS
   parameter frames, the coder rate bits in the trailing byte identify
   the contents and length as per Table 1.

        If I understand this correctly in an RTP payload that contain mulyiplr
        bit-rate frames the safest way of decoding this payload is to work from
        the end of the payload towards the start identifying a frame at a time.
        Then after having figured out how many frames actually are present, one
        can calculate the timestamp value for each frame.
