The Chroma Resampler MegaCore function can process streams of pixel data of the
types shown in
The Clipper MegaCore function provides a means to select an active area from a video
stream and discard the remainder.
The active region can be specified by either providing the offsets from each border, or
by providing a point to be the top-left corner of the active region along with the
region's width and height.
The Clipper can deal with changing input resolutions by reading Avalon-ST Video
control packets. An optional Avalon-MM interface allows the clipping settings to be
changed at runtime.
The Clipper MegaCore function can process streams of pixel data of the types shown
in
Maximum frame width is specified in the parameter editor, the actual value is read from control
packets.
Maximum frame height is specified in the parameter editor, the actual value is read from control
packets.
Progressive.
