13===========
14
15Proprietary multi-planar format used by Intel SR300 Depth cameras, comprise of
16Infrared image followed by Depth data. The pixel definition is 32-bpp,
17with the Depth and Infrared Data split into separate continuous planes of
18identical dimensions.

21
22The first plane - Infrared data - is stored according to
23:ref:`V4L2_PIX_FMT_Y10 <V4L2-PIX-FMT-Y10>` greyscale format.
24Each pixel is 16-bit cell, with actual data stored in the 10 LSBs
25with values in range 0 to 1023.
26The six remaining MSBs are padded with zeros.
27
28
29The second plane provides 16-bit per-pixel Depth data arranged in
30:ref:`V4L2-PIX-FMT-Z16 <V4L2-PIX-FMT-Z16>` format.

33**Frame Structure.**
34Each cell is a 16-bit word with more significant data stored at higher
35memory address (byte order is little-endian).
