[comp.graphics] video integration/interchange

sean@cadre.dsl.PITTSBURGH.EDU (Sean McLinden) (05/29/89)

Please excuse the general and seemingly ignorant nature of this request.

There was, recently, report to comp.graphics a summary of workstation
hadrware to allow video (analog) to be included in a workstation display
(even within an X-based window). It occurred to me as I was reading this
that this was, in fact, a suboptimal solution, in the sense that that
what one would really like is not an integrated display, but a format
for an integrated multimedia file that could be exchanged between sites
much like mail or file transfer currently occurs. The difficulty is
only in part, to get the information from one place to another. The
more significant problem is how to create links between various forms
of data that reflect knowledge about the world.

The question, then, is what do people see as being the most realistic
short (5-10 years) and intermediate (10-20 years) term solutions to
the problem of multimedia record exchange? Will it be a migration to
an entirely digital medium (digital video), or will we move toward
multimodal networks which support separate analog and digital signals
(ISDN? FDDI-II?)?

I'm not looking so much for futuristic predictions as I am for real
world facts, documents, references, etc., as to what people are working
on as approaches to this problem. Specifically, I am not looking at
the higher level associations such as might be captured by a hypermedia
format or a markup language, but what will be the physical layers,
networks, and filesystem structures that will support these higher
level systems.

The purpose of this request is to attempt to develop a rational policy
for the acquisition of equipment and technology for a large academic
medical center which is actively involved in research into new forms
for dynamic patient records. If a discussion of this subject is not
appropriate to this newsgroup, please feel free to E-mail me your
comments and opinions and I'll be happy to summarize for anyone who
has an interest.

I also would be intersted in information about what people think the direction
multi-media mail/OS/etc is going to take.  But I would also very much like to
know is what projects are currently under development.  Please send Email and
I will summarize the responses.
