ITU: The United Nations regulatory body governing all forms of communications.
(previously CCIR) regulates the radio frequency spectrum, while ITU-T (previously CCITT)
deals with the telecommunications standards.
ITU-R601: See CCIR601
PIXEL: The smallest distinguishable and resolvable area in a video image. A single point on the
screen. In digital video, a single sample of the picture. Derived from the words picture
element.
RESOLUTION:
signal. Eight bits is the minimum resolution for broadcast television signals.
4 bits = a resolution of 1 in 16.
8 bits = a resolution of 1 in 256.
10 bits = a resolution of 1 in 1024.
SERIAL DIGITAL:
refer to serial digital television signals.
SMPTE (Society of Motion Picture and Television Engineers): A
recommends standards for the film and television industries.
SMPTE 125M:
signals. SMPTE 125M defines the parameters required to generate and distribute
component video signals on a parallel interface.
SMPTE 259M:
interfaces.
TRS: Timing reference signals used in composite digital systems. (It is four words long).
TRS-ID: Abbreviation for "Timing Reference Signal Identification".
maintain timing in composite digital systems. (It is four words long.)
4:2:2: A commonly used term for a component digital video format. The details of the format are
specified in the CCIR-601 standard. The numerals 4:2:2 denote the ratio of the sampling
frequencies of the luminance channel to the two colour difference channels. For every four
luminance samples, there are two samples of each colour difference channel.
