Additional preview pages of the TDA4780 datasheet.

The TDA4780 is a monolithic integrated circuit with a luminance and a colour difference interface for video processing in TV receivers.

Its primary function is to process the luminance and colour difference signals from a colour decoder which is equipped e.g.

Gamma adjust.
Dynamic black control (adaptive black).
All input signals clamped on black-levels.
Automatic cut-off control, alternative: output clamping on fixed levels.
Three adjustable reference voltage levels via I2C-bus for automatic cut-off control.
Luminance/colour difference interface.
Two luminance input levels allowed.
Two RGB interfaces controlled by either fast switches or by I2C-bus.
Two peak drive limi.
