System description
D1 interface
The D1 interface extracts the luma and chroma pixels from the 8-bit data stream as well as
the ancillary data embedded in the horizontal and vertical blanking interval (VBI). This data
Interrupts
4:2:2 D1 input stream de-multiplexing including ancillary data extraction
Horizontal and vertical decimation by 2 and 4 with horizontal and vertical anti-aliasing
filters (with programmable coefficients)
3D-temporal noise reduction based on a proprietary ST algorithm
Noise level estimator used to control the 3D-TNR through a software loop
Motion estimator to perform film mode detection or scene change detection through a
software loop
