CAT
Conditional Access Table
CAT table is used for conditional access to the streams. It provides
association with the EMM stream.
CAVLC
Context Adaptive Variable Length Coding.
CAVLC is a form of entropy coding used in H.264 video encoding. CAVLC
has lower coding efficiency than CABAC but is less computationally
expensive.
CBR
Constant Bitrate. The bit-rate of the bitstream is constant.
CC
Close Caption.
Chrominance
Chrominance (chroma or C for short) is the signal used in video systems
to convey the information of the picture, separately from the
accompanying luma signal (or Y for short).
CIF
Common Intermediate Format.
A format used to standardize the horizontal and vertical resolutions in
pixels of YCbCr sequences in video signals, commonly used in video
teleconferencing systems (video size: 352p x 288p).
Closed Caption
A TV picture subtitling system used with 525-line analog transmissions.
Codec
Compressor-Decompressor.
A codec is a device or computer program capable of encoding and/or
decoding a digital data stream or signal.
Compression
The process of removing redundant data from audio or video streams to
reduce the amount of data transferred or stored.
CPU
Central Processing Unit.
CrCb
Digital difference signals. These signals, in combination with the
luminance signal (Y), define the and brightness of each picture element
(pixel) on a TV line.

Chrominance.
CW
Control Word.
CWG
Control Word Generator.
DAR
Display Aspect Ratio
DASH
Dynamic Adaptive Streaming over HTTP
dB
Decibel
The decibel is a logarithmic unit that indicates the ratio of a physical
quantity (usually power or intensity) relative to a specified or implied
reference level. A ratio in decibels is ten times the logarithm to base 10 of
the ratio of two power quantities. A decibel is one tenth of a bel, a
seldom-used unit.
dBFS
Decibel Full Scale
De-blocking Filter
An in-loop de-blocking filter is designed to smooth out artifacts introduced
by the compression process in the reconstructed image in both the
encoder and decoder.
Decoder
The device containing the electronic circuitry necessary to decode
encrypted signals. Some Decoders features a receiver.
