Video decoder

The output digital video may be formatted in various ways, such as 8-bit or 16-bit 4:2:2, 12-bit 4:1:1, BT.656 (SD) or BT.1120 (HD).

In the case of composite video, the luminance and chrominance are then separated; this is not necessary for S-Video sources.

Next, the chrominance is demodulated to produce color difference video data.

At this point, the data may be modified so as to adjust brightness, contrast, saturation and hue.

Finally, the data is transformed by a color space converter to generate data in conformance with any of several color space standards, such as RGB and YCbCr.
