Means...
Processor in a video receiver that converts digital video data to
analogue signals for replay on analogue monitors; or in certain
cases a software decoder, a program that decodes digital data for
replay on the PC (decompression etc.).
To recover the information originally impressed on the radio wave.
Means...
The field of force that an electrical current produces around the
conductor through which it flows.
A wave propagating as a periodic disturbance of the electric and
magnetic fields and having frequency in the electromagnetic
spectrum; the means by which energy is transmitted from one
place to another.
Elementary streams: These streams contain only one MPEG-2
video channel and no audio. Elementary streams are required if
you intend to use Milestone or any player that cannot operate
with Transport streams.
You must be in RTSP mode to use Elementary streams.
A processor in a video transmitter which converts analog video
from a camera to digital data.
Means...
Forward Error Correction is a system of error control for data
transmission, whereby the sender adds redundant data to its
messages, also known as an error-correction code. This allows
the receiver to detect and correct errors (within some bound)
without the need to ask the sender for additional data. The
advantage of forward error correction is that a back-channel is not
required, or that retransmission of data can often be avoided, at
the cost of higher bandwidth requirements on average. FEC is
therefore applied in situations where retransmissions are relatively
costly or impossible.
Software which is installed directly on a device and is intended
specifically for that device and is used to control it.
Field of View - The field of view (also field of vision) is the
angular extent of the observable world that is seen at any given
moment.
