Real Time Streaming Protocol (RTSP) is a network
control protocol designed for use in entertainment and
communications systems to control streaming media servers. The
protocol is used for establishing and controlling media sessions
between end points. Clients of media servers issue DVR-like
commands, such as play and pause, to facilitate real-time control
of playback of media files from the server.
Receiver, an electronic device that changes a radio signal from a
transmitter into useful information.
To transmit RF energy.
Any frequency of electrical energy capable of propagation into
space (usually above 20kHz). Also called RF.
Means...
Signal to Noise Ratio is an electrical engineering measurement
defined as the ratio of a signal power to the noise power
corrupting the signal.
Signal-to-noise ratio compares the level of a desired signal (such
as music) to the level of background noise. The higher the ratio,
the less obtrusive the background noise is.
The Shannon limit or Shannon capacity of a communications
channel is the theoretical maximum information transfer rate of
the channel, for a particular noise level.
In electronics, a signal is an electric current or electromagnetic
field used to convey data from one place to another. The simplest
form of signal is a direct current (DC) that is switched on and off;
this is the principle by which the early telegraph worked. More
complex signals consist of an alternating-current (AC) or
electromagnetic carrier that contains one or more data streams.
Streaming is the transmission of digital audio or video or the
listening and viewing of such data without first storing it.
Means...
A transmitter is an electronic device which, usually with the aid
of an antenna, propagates an electromagnetic signal such as
radio, television, or other telecommunications.
