Epilogue Block
The Epilogue Block outputs UV signals from the chrominance block and Y signals from the
luminance block in the format based on the signal obtained by setting of the control register.
In this block, the following modes can be selected.
1) Display of blue back when synchronization fails.
OFF
ON*
2) Output signal Y/CbCr format select
YCbCr
YCbCr
The chrominance signal (U, V component) outputs Cb and Cr data to the C pin in an output
format described later.
4 : 2 : 2*
4 : 1 : 1
3) Selection of 8-bit chroma signal output format
Offset binary*
2's Complement
4) Output pin enable select
High impedance
Output enable*
5) Multiplex signal detect level adjustment
The levels are configured to be variable when detecting data, such as multiplex signal, which is
present for the vertical blanking interval.
If defining 60 as the black level and 200 as the white level, the levels between them are valued as
100 IRE, the data detect levels are set to 8 steps on a 57 IRE basis.
6) Various modes detection
NTSC/PAL detect mode*
Multiplex signal detect mode
HSYNC synchronization detect mode
7) Output signal phase control
6.
I
2
C Control Block
This is the serial interface block based on the I
2
C standard of Phillips Corporation.
This block functions only as a Slave-Receiver.
The external control can set the internal registers (MRA, MRB, HSYT, etc.).
7.
Test Control Block
This block is used to test this LSI. Normally it is not used.
