1.3 Device Description
Flicker-Free Video Encoder with Ultrascale Technology
Flicker filtering and vertical and horizontal overscan compensation are NOT
SUPPORTED in any interlaced RGB or YCrCb input format sent to the
CX25870. Interlaced input data is commonly used for DVD Out from a MPEG2
Decoder chip. Because of the data and image content types, flicker filtering and
overscan compensation are not necessary in this case.
Illustrations showing the before and after effects of overscan compensation
can be found in Figures 1-9 and 1-10.
