The SD CSC matrix scalar uses the following equations:
Y = (a1 × R) + (a2 × G) + (a3 × B) + a4
Pr = (b1 × R) + (b2 × G) + (b3 × B) + b4
Pb = (c1 × R) + (c2 × G) + (c3 × B) + c4
The coefficients and their default values are located in the
registers shown in Table 47.

ED/HD Manual CSC Matrix Adjust Feature
The ED/HD manual CSC matrix adjust feature provides custom
coefficient manipulation for color space conversions and is used
in ED and HD modes only. The ED/HD manual CSC matrix
adjust feature can be enabled using Subaddress 0x02, Bit 3.
Normally, there is no need to enable this feature because the CSC
matrix automatically performs the color space conversion based
on the input mode chosen (ED or HD) and the output color
space selected (see Table 46). For this reason, the ED/HD
manual CSC matrix adjust feature is disabled by default.
If RGB output is selected, the ED/HD CSC matrix scalar uses
the following equations:
R = GY × Y + RV × Pr
G = GY × Y (GU × Pb) (GV × Pr)
B = GY × Y + BU × Pb
Note that subtractions are implemented in the hardware.
If YPrPb output is selected, the following equations are used:
Y = GY × Y
Pr = RV × Pr
Pb = BU × Pb
where:
GY = Subaddress 0x05, Bits[7:0] and Subaddress 0x03, Bits[1:0].
GU = Subaddress 0x06, Bits[7:0] and Subaddress 0x04, Bits[7:6].
GV = Subaddress 0x07, Bits[7:0] and Subaddress 0x04, Bits[5:4].
BU = Subaddress 0x08, Bits[7:0] and Subaddress 0x04, Bits[3:2].
RV = Subaddress 0x09, Bits[7:0] and Subaddress 0x04, Bits[1:0].
On power-up, the CSC matrix is programmed with the default
values shown in Table 48.

When the ED/HD manual CSC matrix adjust feature is
enabled, the default coefficient values in Subaddress 0x03
to Subaddress 0x09 are correct for the HD color space only.
The color components are converted according to the following
1080i and 720p standards (SMPTE 274M, SMPTE 296M):
R = Y + 1.575Pr
G = Y 0.468Pr 0.187Pb
B = Y + 1.855Pb
The conversion coefficients should be multiplied by 315 before
being written to the ED/HD CSC matrix registers. This is
reflected in the default values for GY = 0x13B, GU = 0x03B,
GV = 0x093, BU = 0x248, and RV = 0x1F0.
If the ED/HD manual CSC matrix adjust feature is enabled and
another input standard (such as ED) is used, the scale values for
GY, GU, GV, BU, and RV must be adjusted according to this
input standard color space. The user should consider that the
color component conversion may use different scale values.
For example, SMPTE 293M uses the following conversion:
R = Y + 1.402Pr
G = Y 0.714Pr 0.344Pb
B = Y + 1.773Pb
The programmable CSC matrix is used for external ED/HD
pixel data and is not functional when internal test patterns are
enabled.
Programming the CSC Matrix
If custom manipulation of the ED/HD CSC matrix coefficients
is required for a YCrCb-to-RGB color space conversion, use the
following procedure:
1. Enable the ED/HD manual CSC matrix adjust feature
(Subaddress 0x02, Bit 3).
2. Set the output to RGB (Subaddress 0x02, Bit 5).
3. Disable sync on PrPb (Subaddress 0x35, Bit 2).
4. Enable sync on RGB (optional) (Subaddress 0x02, Bit 4).
The GY value controls the green signal output level, the BU
value controls the blue signal output level, and the RV value
controls the red signal output level.
