ITU:
The United Nations regulatory body governing all forms of communications. ITU-R (previously
CCIR) regulates the radio frequency spectrum, while ITU-T (previously CCITT) deals with the
telecommunications standards.
ITU-R BT.709 An international standard for component digital television from which was derived SMPTE
274M and SMPTe 296M standards.
values and filter characteristics for Y, B-Y, R-Y and RGB high definition component digital
television signals.
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:
The number of bits (four, eight, ten, etc.) determines the resolution of the 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.
RGB
The three primary colour signals: red, green, and blue (RGB) that together convey all
necessary picture information. In normal high definition digital video, these three primary
components are scaled such that the extreme values are code words 040
in a 10-bit representation. See also FSRGB.
SAV:
Abbreviation for "Start of Active Video". A digital synchronization sequence consisting of a
sequence of four consecutive code words (a code word of all ones, a code word of all zeros,
another code word of all zeros, and a code word including F (field/frame), V (vertical), H
(horizontal), P3, P2, P1, and P0 (parity) bits.) which is used to designate the end of the
horizontal blanking interval. The pixel immediately following the SAV is known as pixel 0 and
designates the first pixel of the specific line of the digital image. See also EAV.
SERIAL DIGITAL:
Digital information that is transmitted in serial form. Often used informally to refer to
serial digital television signals.
SMPTE (Society of Motion Picture and Television Engineers): A
recommends standards for the film and television industries.
SMPTE RP 218:2009:
Action and Safe Title Areas for Television Systems. This Recommended Practice provides the
tools for calculating Safe Action and Safe Title Areas of any size. It also defines a set of Safe
Areas, which are given in Annex B. These are legacy safe areas T based on the limitations of
CRT-based displays. and are not reflective of current practice; for current practice, users
should consult SMPTE ST 2046-1 and RP 2046-2.
SMPTE ST 292-1:
The SMPTE standard for 4:2:2 sampled 1.5 Gb/s serial digital video interfaces.
SMPTE ST 299M:
The SMPTE standard for embedding AES audio into HDTV SMPTE ST 292-1 and
SMPTE ST 372 serial digital video interfaces.
SMPTE ST 372: The SMPTE standard for 4:4:4 sampled HDTV Dual Link 1.5 Gb/s serial digital video
interfaces.
