3.1 VIDEO LAYER
Video data is directly transferred from Video Processor to Mixer in YCbCr [888] 4:4:4 formats. As the Video
Processor scales the source image in letterbox mode, the display region of the video data is smaller than the
screen size. In this case, background layer is seen in the blank region.
3.2 GRAPHIC LAYER
ARM or Graphic Accelerator generates the graphic source data in the external memory and they are transferred to
Mixer by AXI access. Mixer supports the following graphic formats.
16bpp RGB [565]
16bpp ARGB [1555]
16bpp ARGB [4444]
