Multi-Media Mail Meeting Notes                           9 February 1982


      on efficient storage and manipulation of multirecipient messages,
      enclosures, citations, etc.

   COMSAT

      Using small 11s, Rapicom 450 and 500 fax machines, also have some
      LPC vocoders.  Substantial work has been done on encoding and
      decoding both Rapicom 450 and CCITT T.4 fax data, and also on
      manipulation of bitmap data (See RFC 803).

   BBN

      Using Jericho (code in Pascal). Will be building a prototype
      system with the aim of investigating problems of data distribution
      and privacy.  Trying to produce portable software currently in
      Pascal but may switch to ADA in the distant future.  Have IP and
      CFTP running, working on TCP. CFTP is a file transfer built
      directly on IP.

   UCL

      Using LSI-11, Rapicom 450 fax machine, Grinell bitmap display.
      May get PERQs (produced by ICL) in future.  Have done quite a lot
      of work on encoding/decoding for the Rapicom 450, and in bitmap
      manipulations (e.g., cleanup of noise, scaling, cut and paste).
      Interests in the relation of other types of display protocols to
      multimedia effort e.g., VIDEOTEXT and TELETEXT.

   SRI

      There are three multimedia mail projects at SRI,sponsored by DCEC,
      ARPA, and NAVELEX.  SRI is a subcontractor (with Sytek and DTI) to
      SDC in the DCEC program to produce protocol specifications for the
      DoD.  SRI has written service specifications for a mail system
      similar to RFC 759+767 with security features added.  The ARPA
      project is studying the issues involved in a multimedia mail
      architecture based on RFC 759+767, including negotiations,
      envelopes, and multilevel security.  The NAVELEX project is
      investigating user interfaces for command and control
      workstations, including natural language access to a data base.
      The plan is to use RFC 759+767 data structures to communicate text
      and graphics, implemented on Foonly F-5s running Tenex with
      Foo-Vision displays.  The current choice for the graphics protocol
      is Bisbey's GL2.
