Dear Paul,

      Thank you for your advice. I have revised the part as follows:

      GEN-1xz: A protocol shall be defined or specified for
      communication over Interface C.

      ==>

      GEN-1xz: One or more protocols may be defined or specified by an
      Application for communication over Interface C.

      Updated version AVD-3995b has been uploaded to the /Incoming.

 Mr Okubo,

        I think the protocol used for Interface C will be defined by the
        applications.  This might be RTP/RTCP or something else, but
        really a choice to be made for the specific application.

Dear Paul,

          I have uploaded AVD-3995a at the /Incoming. According to the
          Monday discussion, the following additions to G-1nn items of
          the Requirements document have been made:

          - Definition of Interface K

          - Protocol for Interface K

          - Protocol for Interface C

          Please note that the third point was not raised at the
          yesterday's discussion, but I have included it to make the
          Requirements document complete by covering all of the
          interfaces (A, B, C, E, K) except interface D that is not
          subject to standardization (see MED-109). 

          One thing needing further consideration is if the protocol for
          Interface C (for media flow) is single or multiple. Currently
          the requirement says: 

          "A protocol shall
            be defined or specified for communication over Interface C."

          In terms of transport, it may be single like RTP, but variety
          of application media may flow through this interface C.

          Best regards,
