Glossary 75
static IP address
An IP address that is assigned to a computer or device once and is
never changed.
streaming Delivery of video or audio data over a network in real-time, as a stream of
packets instead of a single file download.
T
TCP (Transmission Control Protocol) A method used along with the Internet Protocol
(IP) to send data in the form of message units between computers over the Internet. IP takes
care of handling the actual delivery of the data, and TCP takes care of keeping track of the
individual units of data (called packets) into which a message is divided for efficient routing
through the Internet.
temporal compression Image compression that is performed between frames in a
sequence. This compression technique takes advantage of redundancy between adjacent
frames in a sequence to reduce the amount of data that is required to accurately represent
each frame in the sequence. Sequences that have been temporally compressed typically
contain key frames at regular intervals.
track A QuickTime data structure that represents a single data stream in a QuickTime
movie. A movie may contain one or more tracks. Each track is independent of other tracks in
the movie and represents its own data stream.
TTL (time-to-live) A multicast broadcast has a TTL value that is set by the user. It specifies
the number of routers the stream will pass through before it stops propagating over the
network.
tween track A track that modifies the display of other tracks.
U
UDP (User Datagram Protocol) A data transport protocol that does not support
retransmission of lost packets, sometimes used instead of TCP/IP.
unicast The one-to-one form of streaming. If RTSP is provided, the user can move freely
from point to point in an on-demand movie.
URL (Universal Resource Locator) A uniform way of specifying locations on the
Internet or a local file system.
V, W, X, Y, Z
VBR (variable bit rate) A method of compressing data that takes advantage of changes in
the media’s data rate.
WAV A Windows format for sound files.
webcast A broadcast of live video or audio on the Internet.
