Apple Computer recently announced QuickTime Conferencing, a system
extension to the Macintosh operating system, and an additional component
building upon the original QuickTime architectural framework. QuickTime
Conferencing (QTC) is both an end-user and developer technology, focused on
multimedia networking and collaborative applications.

The developer technology consists of a set of open API specifications for
multimedia networking, which allow application, software, hardware and network
developers to easily add media conferencing to applications. QTC is
compression, transport, protocol and media device independent. QTC allows for
support of both standards based protocols (such as the worldwide
teleconferencing standard H.320), along with proprietary protocols. The
software allows for both multiparty conferencing and broadcast type
applications supporting point to point, multipoint and multicast connection
models. QTC runs on a variety of networks, such as Ethernet, ISDN, Token Ring
and ATM, and initially uses the AppleTalk and TCP/IP network protocols. The QTC
technology brings with it some new elements, such as a software based H.261
codec for PowerPC, and extensions to the AppleTalk protocol for multicasting on
enterprise networks.

The end-user component of QTC is a software application, called Apple Media
Conference, which allows users to engage in multiparty conferencing, share and
annotate multimedia data, broadcast digital audio and video on to a network and
to record conversations into QuickTime movies. Via support of the H.320
teleconferencing standard along with an AV plug-in card, QTC users can video
conference with users of H.320 systems in the PC and PC compatible world,
allowing for cross-platform video conferencing interoperability.

QTC is considered a software foundation on which interoperable conferencing
applications can easily be built. These applications can stay the same, as the
underlying network quality of service guarantees improve and the evolving
information highway gets wider and faster digital pipes.

This seminar will be broadcast on the MBONE starting promptly at 2:30.  
405 Soda Hall is a relatively small seminar room (approx. 25 seats).  Folks at 
Berkeley might want to attend the seminar by watching it on your workstation, 
if it can receive MBONE transmissions.  For further information on accessing 
the MBONE contact see the FAQ (/usr/sww/doc/faq/mbone.faq).
