Chapter 12: Video Input Processor
– Enables non-linear horizontal aspect ratio conversion using normal 6-tap
polyphase filter.
– Permits optional linear phase interpolation / nonlinear phase interpolation (as
in MBS).
• 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.
