Y Offset
The 8 bit Y offset adds any offset required in the Y or RGB
data outputs. For example 64 (16) for the 64 (16) to 940
(235) 10 bit (8 bit) 601 outputs. When the output is YC
B
C
R
this offset is applied to the luminance data only. The Y offset
also provides the blanking level for RGB
outputs with syncs.
Matrix Limiters
The different limiters are listed below, 10 bit data is
assumed.
Table 13. Matrix Limiters
Examples of Output Matrix Operation
From the SMPTE-170M specification:
YC
B
C
R
data ranges are:
Y data range is 64 to 940 (876)
C
B
C
R
data ranges are 64 to 960 (+/- 448)
Matrix programming:
YGx = (876 / 540) = 1 + (159/256)
UGx = (448 / 236) = 1 + (230/256)
VGx = (448 / 332) = 1 + (89/256)
YOFF = 64
PED = 44
PAL digital composite input and RGB (0-1023) outputs:
The nominal scaling factors are simply:
YGx = 1023/572 = 1 + (202/256)
UGx = (1023/572)*(1/0.492) = 3 + (163/256)
VGx = (1023/572)*(1/0.877) = 2 + (10/256)
YOFF= 0
PED = 0
It is also possible with the architecture supplied to use the
limiters on the output of the matrix to clip the output video
deliberately by using a slightly larger gain than is required.
The Y_Offset can achieve the same by setting its value to be
one lsb less than the minimum clip level.
Buffer Registers
The BUFFER pin allows the user to externally switch
between two sets of internal registers that have the same
function. This register buffering allows the matrix gain,
picture hue, and luma offset to be changed at a known time
relative to the input data.
Registers 17 to 1D are selected when the BUFFER pin is
LOW and registers 27 to 2D are selected when the BUFFER
pin is HIGH. If the msb of the decoder product code DPC
2
is
LOW, an 8 bit decoder has been selected and the bottom 2
bits of registers 17 to 1A and 27 to 2A are forced to zero.
