Some commercial video providers also offer
special encoders are used to record, encode, and begin streaming digital video of an

customers get the latest information via digital video, because the viewer sees the
event nearly as it happens, the only delay being the minimal time necessary to
encode and deliver each moment of the event. Viewers can also pause, restart,
rewind, and fast forward the video up to the current "live" point.

Where is Digital Video Used?

Digital video can be used in many environments. This section describes some
example, divided into the broad categories broadband, enterprise, and Internet.

Broadband

The broadband environment is characterized by high-speed delivery of complex
video data, such as would be required by full-screen, full-motion video. This data
need not necessarily represent long videos (for example, a home-shopping segment
might be 2-3 minutes or less), but will include a great deal of digital-video
information.
Typically, this environment requires the use of a dedicated set-top box, a special
receiving and decoding device attached to a display such as a television monitor.
Examples of broadband usage would include:
Subscription-service delivery of a digitally recorded event such as a blacked-
out athletic game
Movies, concerts, Broadway shows, or other events delivered on demand
News on demand
Product and service directories
Distance learning

One-Step Encoding
