Postprocessing Features 

 YCbCr 4:2:0 planar

 YCbCr 4:2:0 planar

 YCbCr 4:2:2 (YUYV)

Internal source: VDEC decoder

External source: e.g. a software decoder or camera interface

YCbCr 4:2:0 semi-planar

YCbCr 4:2:2 (YUYV)

Fully configurable ARGB channel lengths and locations inside 32 bits, e.g. 
ARGB 32-bit (8-8-8-8), RGB 16-bit (5-6-5), ARGB 16-bit (4-4-4-4)

48 x 48 to 4672 x 3504 (16 Mpixels)

Step size 16 pixels

48 x 48 to 2048 x 2048 (4 Mpixels)

Step size 16 pixels

16 x 16 to 1280 x 720

Horizontal step size 8

Vertical step size 2

Bicubic polynomial interpolation with a four-tap horizontal kernel and a 
twotap vertical kernel

Arbitrary, non-integer scaling ratio separately for both dimensions

Maximum output width is 3x the input width (within the maximum output

image size limit)

Maximum output height is 3x the input height – 2 pixels (within the 
maximum output image size limit)

Proprietary averaging filter

Arbitrary, non-integer scaling ratio separately for both dimensions

Unlimited down-scaling ratio (e.g. from 16Mpixel to QVGA)

BT.601-5 compliant [12]

BT.709 compliant [13]

User definable conversion coefficient

2x2 ordered dithering for 4-, 5- and 6-bit RGB channel precision

Conditional area-based deinterlace filtering

Constant eight bit value can be set to the alpha channel of the 24-bit RGB 
output data to control the transparency of the output picture. The resulting 
32-bit ARGB data can be used as input data for later alpha blending.

 YCbCr 

semi-planar 4:2:0 PP output format is not supported when performing 
alpha blending.

The supported overlay input formats are following:

- 8 bit alpha value + YCbCr 4:4:4, big endian channel order being A-Y-Cb-
Cr, 8 bits each 

- 8 bit alpha value + 24 bit RGB, big endian channel order being A-R-G-B, 8 
bits each

Segmented linear
