1.1
This standard defines a family of image sample structures for the representation of stationary or moving
two-dimensional images sampled temporally at a constant frame rate and having an image format (sample
structure) of 1920 x 1080 and an aspect ratio of 16:9 as given in table 1. This standard specifies:
– R’G’B’ color encoding;
– R’G’B’ analog and digital representation;
– Y’P’
B
P’
R
color encoding, analog representation and analog interface; and
– Y’C’
B
C’
R
color encoding and digital representation
An auxiliary component A may optionally accompany R’G’B’ and Y’C’
B
C’
R
; these interfaces are denoted
R’G’B’A and Y’C’
B
C’
R
A. The “A” component if present shall have the same characteristics as the Y’ or G’
channel.
1.2
This standard specifies multiple frame and field rate formats (table 1) and eight-bit, ten-bit and twelve-bit systems. It is
not necessary for an implementation to support all formats to be compliant with this standard. However, an implementation
must state which of the formats are supported. Interfaces for twelve-bit systems require more than a single link.
