7.12.2
Video image data is stored in memory with one table for
each of the Y, U and V components. This is called planar
format. This is shown in
data. The EVO merges bytes from each of the three ta-
bles to generate the CCIR 656-compatible output data.
The U and V tables have the same number of lines but
half the number of pixels per line as the Y table. The
transfer is the same for YUV 4:2:0 format except the U
and V tables will be 1/4 the size of the Y table. The U and
V tables have the half the number of lines and half the
number of pixels per line as the Y table.

Graphics overlay image data is stored in a pixel-packed
format in SDRAM. Graphics images are stored in YUV

4:2:2+alpha format.
YUV overlay area is always within the image output res-
olution. The EVO does not upscale the graphics overlay
image. If the EVO is upscaling the video image by 2 , the
graphics overlay must be provided in upscaled format.
Pixel data is a 16-bit data and follows endian-ness con-
ventions based on 16-bit data. Refer to

The memory video image data formats are converted to
the output YUV 4:2:2 co-sited format and optionally up-
scaled 2 horizontally. The conversion algorithms are
