(picture only) signal before
it is combined with a sound signal and modulated onto an
RF carrier. Composite
video is often designated by the CVBS acronym, meaning
"Color, Video, Blank and Sync". In German (with PAL
being a German invention by Telefunken's Walter
Bruch) the abbreviation FBAS (Farbe-Bild-Austastung-
Synchron) means the same.
It is usually in standard formats such as NTSC, PAL, and
SECAM. It is a composite of three source signals called
Y, U and V (together referred to as YUV) with sync
pulses. Y represents the brightness or luminance of the
picture and includes synchronizing pulses, so that by itself
it could be displayed as a monochrome picture. U and V
represent hue and saturation or chrominance; between
them they carry the color information. They are first
modulated on two orthogonal phases of a color carrier
signal to form a signal called the chrominance. Y and UV
are then combined. Since Y is a baseband signal and UV
has been mixed with a carrier, this addition is equivalent to
frequency-division multiplexing.
Conditional Access System Several companies provide competing Conditional Access
Systems; Irdeto Access, Nagravision, Conax, Viaccess,
Verimatrix and NDS are among the most commonly used
CAS systems.
DiSEqC Stands for Digital Satellite Equipment Control. It is a
