• Black & Blank Pedestal

This block adds sync signals at the luminance side to luminance signals.

• Interpolator +LPF

This block executes data interpolation and the elimination of high frequency components by

LPF for input chrominance signals. Both 4:2:2 and 4:1:1 signals are processed.

Internal registers MR and CR can be set from the master side.

When writing to the internal registers other than MR [5] (black level control) and CR [1:0]

(overlay level), written contents are immediately set to them. It is during the vertical blanking

period that written contents are set to MR [5] and CR [1:0].

• Sync Generator & Timing Controller

This block generates sync signals and control signals.

This block is operated in slave mode, which performs external synchronization, and in master

mode, which internally generates sync signals.

• Color Burst Generator

Outputs U and V components of amplitude of burst signals.

• Subcarrier Generator

Executes color subcarrier generation.

• Interpolation Filter (IPF)

This block performs upsampling at CLK X 2 (double speed CLKX1) for luminance signals and

chrominance signals modulated with CLKX1. Interpolation processing is executed in this

process.
