                     Multimedia Mail Meeting Notes




Introduction

   A meeting was held at USC Information Sciences Institute on the 12th
   of January 1982 to discuss multimedia mail issues and experiments.
   The list of attendees is at the end of this memo.

Overview:

   This meeting was called to discuss common interests in multi-media
   computer mail experiments, and to agree on some specific initial
   experiments.

Review of Status:

   Review current status of multimedia efforts at CMU, ISI, MIT, COMSAT,
   BBN, UCL, SRI.

   CMU

      Using PERQ, Quip for fax, LPCM vocoder from LL, will get NEC board
      (3 chips) to replace vocoder.  Will have a stand alone voice I/O
      device that operates at 2400 baud (not packetized). Not working on
      IP/TCP.  Will use the IP and TCP from the BBN project. Already
      using the BBN Jericho developed Pascal IP and CFTP. Interested in
      word recognition of LPC digitized voice data. Planning to package
      a synthesiser, an analyzer, and a pitch tracker on one board.

   ISI

      Using TOPS20 (code in BLISS10), and starting to use PERQ (code in
      Pascal), RAPICOM 450 for fax.  Main interest is in the data
      structuring and message transport protocols.

   MIT

      Using Apollos, will program in MDL.  Use of Apollos still limited
      due to (1) MDL not completely implemented, (2) network interface
      not yet available (waiting on multibus  to then interface to
      Ethernet). Will get NEC CCITT fax machine. Looking into VAX+BBN
      BitGraph for future.  Main work to date in  design for sharing
      message data in a conceptualy centralized filing system.  Emphasis
