#video over network
10 messages in this thread
Hi,
Does anybody here knew of a product, wich allows to digitize video (lo-mid
quality, only suveillance-quality) on one station in a network and to view it
on another station (Transport is Ethernet) ?
I would appreciate any answer

Markus,
are you looking for real-time digitization _and_ transmission or digitize to a
file and then that file can be played back later.

->are you looking for real-time digitization _and_ transmission or ->digitize

The idea is to view it realtime, or near realtime, the max. of delay should be
1 to 2 seconds.

Markus,
I am not sure if networking technology is there yet. 10Mb/s seems to be about
as fast as these things go (at least commonly) which would be a little over
1MB/s. Now that may be some sort of burst rate also, I am not sure. Maybe it
would be possible… 20KB/frame at 15fps would be what… 300KB/s… hmmm. Ok,
maybe the harware is there… some sort of real-time pipe software is in order
and may or may not exist.

Hi John,
I think about a product wich is a combination of soft- and hardware, i.e. a
M-JPEG-Card or MPEG, or stuff like this! I've got a Movie-Machine from FAST in
combination with a M-JPEG-Compression- Decompression Board, but I can only
create AVI's for CD-ROM playback 300kB/s or less, with loss of quality. So
that's the way I think the product should be.
So, when the video is compressed, and only 1/4 of a screen and b/w, there are
only a 30-40kb/s, and this should be no problem !

There are a number of products on the market you might want to look at. I work
at Lotus on a product called Video for Notes, which allows the distribution on
video accross the network via Lotus Notes (see press release below). Is this
something like what your looking for ?

Lotus Video for Notes Release 1.0 Ships
Enables Capturing, Recording, Editing and Distribution
of Full-Motion Digital Video in Notes Documents
ORLANDO, Fla., Jan. 23, 1995 — Lotus Development Corp. today
announced the immediate availability of Lotus Video for Notes
Release 1.0 (Video Notes), a Lotus Notes Companion Product that
incorporates stored digital video into Notes documents and
distributes video over local- and wide-area networks.
This new multimedia extension to Notes allows workgroups of all
sizes to capture, record, play, edit and distribute full-motion
video in Notes applications, using intuitive buttons similar to
a VCR. With Video for Notes, stored video can be accessed,
distributed and managed as another data type within Notes.
"Video for Notes offers our customers new solutions for
managing their business processes through a whole new class of
strategic applications using full-motion video," said Jeff
Papows, vice president, Lotus' Communications Business Group.
"This product breaks through the barriers to using video in a
business practical manner by making video easy to use and
practical to deploy enterprise-wide through Notes."
Using Video for Notes
Video for Notes will benefit users in all market segments. For
example, an advertising agency can embed video clips in Notes
to assist in the creative review and approval process. This
multimedia interaction ensures that an ad campaign meets
business objectives. Using Video for Notes allows all members
of the creative process — from copywriters, video producers,
account executives and the client — to collaborate more
efficiently and effectively, no matter where they are located.
New York University is using Video for Notes as an innovative
means for students to participate in a virtual college.
"I am impressed with Video for Notes and believe it is a
significant asset for facilitating corporate training and
distance learning," said Richard Vigilante, director,
Information Technologies Institute, New York University.
"Video for Notes will be the killer application for video-based
training in the 1990s." Users also can view video when
disconnected from the network. For example, a traveling
salesperson with product video footage or testimonials could
download video to a laptop, then play the video at the customer
site to illustrate a point, showcase a product or deliver
testimonials.
Video for Notes is Easy for Administrators
Video for Notes has a secure, flexible replication and
distribution model that allows administrators to balance user
demands easily. The Lotus Video for Notes site manager
distributes video to Notes users by generating a single copy of
the video at each location regardless of how many times the
video appears in mail messages or other documents. This
distribution mechanism minimizes long-term storage problems.
Video for Notes also allows the administrator to introduce
gradually video into an enterprise-wide network and make video
available to the entire workgroup regardless of size or current
network connections. Video for Notes provides direct and
immediate playback from video servers for high capacity
local-area networks. When a local-area network does not permit
continuous playback, staged playback is available. Staged
playback allows video to be downloaded automatically from a
server to the desktop and then viewed. For workgroup members
that do not have wide-area networks, Video for Notes
applications can be distributed through CD-ROM.
Building An Industry of Groupware Video Applications
For Lotus' more than 8,000 Business Partners, Video for Notes
provides a robust application development environment for
development of video servers and video editing environments.
It also offers system integrators, consultants and independent
software vendors new opportunities to integrate video into
their products. In addition to standard network file
systems, Video for Notes initially supports two video server
software products from Partners Novell and Starlight Networks.
Lotus Business Partners including DSSI, GroupQuest and Hayes
Computer Systems Inc., are currently working with Video for
Notes to build and integrate video applications as well as
develop vertical market extensions.
Pricing, Availability and System Requirements
Initially, the Lotus Video for Notes site manager is available
on an OS/2 based Notes server. Lotus Video for Notes requires
Lotus Notes Release 3.1.5 or above client and Release 3.2 or
above server software, running a 486 or Pentium processor.
Each site manager license is available for an estimated retail
price of $2,695. Video for Notes requires both a Lotus Notes
client and a Video for Notes client. The Windows-based Video
for Notes client software is available for an estimated retail
price of $120. Video for Notes is currently available in North
America from Lotus by calling 1-800-343-5414 or through Lotus
Business Partners.
Lotus Notes is the industry standard client-server platform for
developing and deploying groupware applications. It allows
people to access, track, share and organize information in ways
never before possible, even if they are only occasionally
connected to a network. Nearly 4,000 companies and more than
one million people use Notes to improve business processes,
including customer service, sales and account management, and
product development.
Lotus Development Corp. (NASDAQ: LOTS), founded in 1982, offers
high quality software products and support services that
reflect the company's unique understanding of the new ways in
which individuals and businesses must work together to achieve
success. Lotus' innovative approach is evident in a new class

Hi Arthur,
Thanks for the msg and the press release.
It is very interresting, you new product!
Do you also have any technical documentation about resolution, speed
requirement of the network and hardware base to playback or view videos? Is it
also possible to view realtime-videos, wich will be digitized on the server and
shown on the clients?
Our application is a big worldwide Hotel-Organisation, and they are also very
interrest in these products !
Thanks for your info -Markus Schwitter
Yes, we do have a white paper that contains more technical details on the
product. I have it back at work, I'll upload it Monday.
As far as the resolution of the video we're currently supporting Video for
Window's AVI files. Without special video acceleration you can play videos at
320×240 resolution on a fast 486. Since we're sitting on top of Video for
Windows you can look at ant AVI file with the Media Manager that comes with
Windows to get a sense of the quality of video that's possible. The real value
added of Video for Notes is how we use Notes as the container of video
references.
The question around video streaming accross the network is a little more
complicated since it's really depends on your current network load. For
example, Video for Windows files usually have anywhere from a 1.5 to 5 megabit
rate. If your network is standard ethernet, 10 mbits, you can play any video
you want provided your getting the full 10mbits. If you have a lot of network
traffic you need to think about how your network is configured. If your
interested in doing realy heavy network video you might want to look at
segmenting your network or implmenting a solution that will give you more
bandwidth such as fast ethernet or ATM.
I'm not sure about your second question about real time video. Are you
interested in a video conferencing product like Intel's Proshare ? Let me
know.
What is the final application that the hotel wants to immplement ?

Yes, this could be a solution!

They wanna have a look at the reception / pool / bar from every PC in the
hotel, without a special cabling system for video in the hotel. The main
application is for surveillance purposes, no inhouse entertainment or stuff
like this.

Hi, Arthur;
I've read your message to Markus Schwitter and I am highly interested in
real-time video over network .My company is looking for a product to be
implemented on LAN/WAN.
Could you give me info on Intel's DTV product (video qulity, frames/sec,
multipoint avalibale or not) or suggest me any other product in the market .My
company urgently needs one to satisfy the communication needs of two deparments
in remote LAN's, but not for training purposes . We are looking for a product,
if there are any, which allows us to transmit voice,audio and data on the same
line, a token-ring of 16Mb and 512K bandwidth.
Any suggestion on the subject will be highly appreciated…
