Notes to
(1) 4:2:2 and 4:2:0 subsampling are not available for the RGB color space.
(2) Vertical subsampling and interlacing cannot be used when the height of the output is not even. The GUI does not allow such a parameterization
(3) Vertical subsampling and interlacing are incompatible with each other and cannot be selected simultaneously in the GUI.
and the behavior of the MegaCore function is undefined if the height is subsequently set to an odd value through the run-time control.

The Test Pattern Generator cannot produce interlaced streams of pixel data with an
odd frame height. To create interlaced video streams where F0 fields are one line
higher than F1 fields, Altera recommends feeding Test Pattern Generator progressive
video output into the Interlacer MegaCore function.
The Video and Image Processing Suite MegaCore functions do not continuously
process data. Instead, they use flow-controlled Avalon-ST interfaces, which allow
them to stall the data while they perform internal calculations.
During control packet processing, the MegaCore functions might stall frequently and
read/write less than once per clock cycle. During data processing, the MegaCore
functions generally process one input/output per clock cycle. There are, however,
some stalling cycles. Typically, these are for internal calculations between rows of
image data and between frames/fields.
Width selected in the parameter editor. Can be run-time controlled in which case, the value
specified in the GUI is the maximum allowed value.
Height selected in the parameter editor. Can be run-time controlled in which case, the value
specified in the GUI is the maximum allowed value.
Mode selected in the parameter editor.
Number of bits per color sample selected in the parameter editor.
