Multimedia Mail Meeting Notes
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.
This meeting was called to discuss common interests in multi-media
computer mail experiments, and to agree on some specific initial
Review of Status:
Review current status of multimedia efforts at CMU, ISI, MIT, COMSAT,
BBN, UCL, SRI.
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.
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.
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

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