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

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 protoc...
