Product data sheet
8.1.5.2 Input and output video scaler
8.1.6 Upsampler
The scaler will convert the standard definition (high definition respectively) video signals
(480i/576i, 480p/576p and 720p, 1080i respectively) into 1080p as described in
Remark: All 4 : 2 : 2 input video formats can be bypassed, as well as all RGB and
YCbCr 4 : 4 : 4 input data, which will be directly fed to the color space converter.
The incoming YCbCr 4 : 2 : 2 (2
8-bit YCbCr 4 : 4 : 4 (3
chrominance pixels.
