| Video Compression: |
The process through which a complete video file
is reduced in size. Video Compression algorithms
take advantage of the fact that there is minimal
difference from "one" frame to the next.
The first frame is encoded and then the sequence
of differences between frames. This is also known
as "inter-frame" coding or "3D coding". |
| Video Hotlinks: |
Hyperlinks that are embedded in video images much
like image maps. Users can click on certain parts
of a video image and be taken to a URL, a new movie,
a different part of the same video, or many other
actions. |
| Video On Demand: |
Describes video content which may be viewed by
the end-user from beginning to end, at any time. |
| Video Service
Provider: |
(VSP) - Video Service Providers are analogous
to Internet Service Providers (ISPs) except that
they specialize in providing multimedia storage
and streaming services for Internet sites. In this
scenario, when a company offers streaming applications
on their Internet site, clicking on the video or
multimedia file will transparently connect users
to the Video Service Provider that stores and streams
the content. |
| VOD: |
See Video On Demand. |
| Voice Over IP: |
(VoIP) - The practice of using an Internet connection
to pass voice data using IP instead of using the
standard public switched telephone network. This
allows a remote worker, for instance, to function
as if directly connected to a PBX even while at
home or in a remote office. In bypassing the public
network, it also avoids standard long distance charges,
as the only connection is through an ISP. VoIP is
being used more and more to keep corporate telephone
costs down. |
