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

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

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