154 Xing Distributed Media Architecture: XDMA Applications
Applications requiring "media on-demand" benefit from XDMA's
simplified approach. The advantage becomes most apparent in
applications with a combination of "on-demand" and "live" media
delivery requirements, especially when the clients are geographically
dispersed. NBC is using XDMA to deliver multiple simultaneous live
financial and news video broadcast channels to financial market
subscribers (money managers, stock brokers, financial analysts) in
cities throughout the US and Europe as part of their "NBC Desktop
Video" service. Xing is developing similar delivery services for
other commercial TV and radio programmers.
Although commercial broadcast services provide very visible and
compelling examples for Xing's capabilities, the largest volume
applications for "streaming media" will be in corporate, educational,
government and health-care networks with "on-demand" and "live"
communication requirements, including training, presentations, status
reporting, and occassionally, entertainment. Because of the rapid
proliferation of TCP-IP / HTTP / HTML ( Internet + World Wide Web +
Mosaic), the infrastructure for integration of Xing "streaming media"
architectures is quickly developing.
Representative XDMA applications include:
* Commercial broadcast delivery systems;
* Internet Service Provider delivery of radio and TV programming;
* On-line marketing, sales, service and customer support;
* Enterprise-wide training, corporate information systems and regulatory
compliance;
* Medical information systems, including live monitoring and on-demand
multimedia information retrieval;
* Educational systems for live and on-demand distance learning as well
media production;
* Government networks for live and on-demand delivery of news events
and briefings to policy makers and dissemination of public information;
* Media production and distribution; and
* Information archives
