Consortium Captures Captioning The World Wide
Web Consortium (W3C) has commissioned a working group
to develop standards for text captioning of streaming
video. The Timed
Text Working Group will base the standards on
XML and hopes to further bridge the gap for disabled
individuals seeking to use the multimedia features
of the Web. "This is not just for the slacker
in the office, but for people with disabilities to
capture the information in the audio stream,"
said W3C representative Janet Daly.
Hole Exposed Several popular video-conferencing
systems -- including the popular Polycom Viewstation
-- are found to have a hole that could allow malicious
hackers to snoop and distribute private broadcasts.

OpenH323 project aims to create a full featured, interoperable,
Open Source implementation of the ITU H.323 teleconferencing protocol
that can be used by personal developers and commercial users without
charge. OpenH323 development is coordinated by an Australian company,
Equivalence Pty Ltd, but is open to any interested party. Commercial
and private use of the OpenH323 code, including use in commercial
products and resale, is encouraged through use of the MPL (Mozilla

Perfect Video Digital video has infiltrated our lives. Cable
providers are selling digital video to compete with satellite providers,
which have been promising better video and audio to consumers. DVDs
are making inroads and bringing hours of high-quality video and
audio to a disc the size of a CD. Enterprise customers, too, are
finding uses for broadcast-quality video, whether for internal security
or for broadcasting corporate meetings.
or Software: Wading the Video Stream Wait a second! Your users
aren't watching full-screen movies at their desktops. They're doing
serious work. Corporate training. Videoconferencing. Distance learning.
But they'll do it better if they can see clear, full-motion images
on their computers. Bringing video to the desktop is an important
cost-saving step for the enterprise. Your job is to find the best
technology to deliver it to your staff and partners.
Playing: Streaming Video Tuned in to IP video lately? It's come
a long way, both in quality and in cost. And it's getting a serious
viewing from companies contending with far-flung staffs and reduced
travel budgets: They're learning just how kind to the bottom line
videoconferencing and video training can be.
Video: A Look Behind the Scenes Over the last few years there
has been a dramatic improvement in the quality of IP-based network
media technologies. Both real time and on-demand media can now be
created, served and played at the desktop using PC-based platforms
and software freely available across the Internet.

the Bells crush Net calling? Telephone calls traveling
over the Internet are surging in popularity. From
virtually nothing a few years ago, Internet-based
calling now comprises an estimated 10 percent of international
calls. While domestic numbers vary between 1 percent
and 5 percent, there is broad agreement that Internet
calling is quickly growing.

We must be blunt about the current system's threats to free speech,
intellectual freedom, and the free flow of information. We must
be careful not to be trapped in nihilistic rhetoric about the "end

logical step to use this infrastructure for a new kind of applications
and tools to facilitate remote collaboration between project partners
at different sites.
