Allows color-space conversion (mutually exclusive with scaling) on the video
path.
Allows 4:2:2 to 4:4:4 conversions on the video path.
Provides last-pixel-in signals, for VBI and video data, to the GPIO block for
Timestamping.
Features interrupt generation, for VBI or video data written to memory.
Provides an internal Test Pattern Generator with NTSC, PAL, and variable format
support.
Features a wide variety of output formats such as planar YUV 4:4:4, planar YUV
4:2:2, planar RGB, semi-planar YUV 4:2:2 packed UYVY, etc. Planar formats are
mutually exclusive with the VBI capture.
Input
ports
Enables non-linear horizontal aspect ratio conversion using normal 6-tap
polyphase filter.
Permits optional linear phase interpolation / nonlinear phase interpolation (as
in MBS).
