Where is Digital Video Used?

Internet

The Internet environment is typically oriented toward delivery of digital video
over public Internet pages. Most people still connect to the Internet via modem,
and this environment is often referred to as "low-bitrate" because of the constraints
imposed by modems with a relatively slow rate of delivery—a "low bit rate."
Although many newer modems boast speeds that seem very fast in comparison to
older modems, they are still extremely slow compared to the delivery rates of a
broadband environment, and this slower delivery rate must be taken into account
when planning digital-video delivery for this environment.
Internet users who connect via a modem will connect with their Internet Service
Provider (ISP), who provides access to the OVS through the Internet. Through a
single connection, the client communicates with the ISP using PPP (Point-to-Point
Protocol) and with the OVS using either TCP/IP or UDP/IP (Transmission Control
Protocol or User Datagram Protocol/Internet Protocol).
Because of its increasing availability and affordability, DSL has also become a
popular way to access the Internet. Although high-bitrate transports like DSL are
avialable, as the administrator of a video-based Web site, you should plan for the
slowest transport system that is likely to access your site, rather than relying on
your clients to have a faster one.
There are many innovative uses for Internet-based delivery of video, including:

Information stored in a "corporate repository" and available for retrieval as
needed—for example, detailed step-by-step instructions for enrolling in your
company's 401(k) program, instructions for installing a piece of equipment, or
an introductory tour of the new cafeteria.
Advertising. Many commercial locations now have Web sites that feature
informative digital video to acquaint you with their product.
News. You can subscribe to news-delivery Web sites that offer not only still
photos (as in an "online newspaper") but full-motion digital video of breaking
stories.
Site tours. Some sites, especially those for large academic institutions, are large
and complex enough that they offer video orientation to the Internet site, the
institution itself, or both.
