2.2.2. RGB Pixel Packing

The Intel FPGA Streaming Video Protocol specifies a packing scheme for RGB pixels.
Figure 20. 1 pixel in parallel, 24 bit RGB video packetThe figure shows a video packet with one pixel in parallel and RGB24 pixels.

The least significant symbol of an RGB pixel must always be blue. With 8 bits per color plane, each RGB24 symbol occupies one byte of TDATA, TDATA is 24 bits wide and no padding is required.
