RGB format

Characteristics:
• Raster format
•
RGB
• Interleaved: one buffer: R, G & B interleaved: BRGBRGBRG, etc.
•
Optimized for display output
The RGB planar format is compatible with standard OS frame buffer display formats.
Only 16 BPP (bits per pixel): RGB565 (2 pixels per 32-bit word) is supported.
The 24 BPP (palletized format) and grayscale formats are not supported. Pixels are stored
in a raster scan order, that is from top to bottom for pixel rows, and from left to right within a
pixel row. Pixel components are R (red), G (green) and B (blue). All components have the
same spatial resolution (4:4:4 format). A frame is stored in a single part, with the
components interleaved on a pixel basis.

YCbCr format

Characteristics:
•
Raster format
•
YCbCr 4:2:2
•
Interleaved: one Buffer: Y, Cb & Cr interleaved: CbYCrYCbYCr, etc.
Pixel components are Y (luminance or "luma"), Cb and Cr (chrominance or "chroma" blue
and red). Each component is encoded in 8 bits. Luma and chroma are stored together
(interleaved) as shown in
