Features:
• Two input data formats
-4:2:2 luminance and chrominance parallel (2 x 8 wires)
-ITU-R 656 data format (8 wires)
• Two different representations of input chrominance data
-2‘s complement code
-Positive dual code
• Flexible input sync controller
• Flexible compression of the input signal
-Digital vertical compression of the input signal (1.0, 1.25, 1.5, 1.75, 2.0, 3.0, 4.0)
-Digital horizontal compression of the input signal (1.0, 2.0, 4.0)
• Noise reduction
-Motion adaptive spatial and temporal noise reduction (3D-NR)
-Temporal noise reduction for luminance frame based or field based
-Temporal noise reduction for chrominance field based
-Separate motion detectors for luminance and chrominance
-Flexible programming of the temporal noise reduction parameters
-Automatic measurement of the noise level (5 bit value, readable by I²C bus)
