of whether a jitter exists or not. Some VTR may disturb synchronization.

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

4 : 1 : 1

YCbCr

4 : 2 : 2*

The chrominance signal (U, V component) outputs Cb and Cr data to the C pin in an output

format described later.

3) Selection of 8-bit chroma signal output format

Offset binary*

2's Complement

4) Output pin enable select

High impedance

Output enable*

The Epilogue Block has a high impedance priority cascade control function to enable the bus

connection of output signals. The target tristate buses are Y, C, HSYNC_L and VSYNC_L, and

this block makes an output enable instruction for these signals

5) Luminance signal phase adjustment

normal*

forward 1 clock

backward 1 clock

6) Chrominance signal phase adjustment

normal*

forward 1 clock

backward 1 clock

I2C Control Block

This is the serial interface block based on the I2C standard of Phillips Corporation.

This block functions only as a Slave-Receiver.

The external control can set the internal registers (MRA, MRB, HSYT, etc.).

Test Control Block

This block is used to test this LSI. Normally it is not used.
