YC Separation Video Decoder

A video decoder that converts either the NTSC/PAL video signal or component video signal into the digital video

signal is incorporated, which is compatible with the composite video signal, S video signal, and component video

signal (480i).

Resolution Conversion

Two-dimensional IP conversion, and expansion/contraction processings available

1. Interlace progressive conversion (IP conversion)

Two-dimensional IP conversion possible for NTSC/PAL input

2. Horizontal vertical scaler functions

Expansion/contraction to VGA size possible. Expansion/contraction possible independently in horizontal and

vertical directions. Full-screen display and zoom display possible.

Enhancement Functions

Various enhancement functions are available. Picture quality adjustment can be made appropriate to characteristics

of LCD-TV.

1. Adjusting the TV picture quality

1-1. Contour correction (horizontal vertical)

Contour correction of the input luminance signal. Adquate peaks are added around the contour.

In this case, coring adjustment is possible to prevent emphasizing of the peak amount and extremely small

noises.

1-2. Color

Saturation can be adjusted by adjusting the color gain of input color-difference signal.

1-3. Hue

The hue of the screen as a whole can be adjusted.

1-4. Luminance

Luminance of the screen as a whole can be adjusted.

1-5. Contrast
