+Infrared 10-bit linked with Depth 16-bit images
+
+
+Description
+===========
+
+Proprietary multi-planar format used by Intel SR300 Depth cameras, comprise of
+Infrared image followed by Depth data. The pixel definition is 32-bpp,
+with the Depth and Infrared Data split into separate continuous planes of
+identical dimensions.
+
+
+
+The first plane - Infrared data - is stored according to
+:ref:`V4L2_PIX_FMT_Y10 <V4L2-PIX-FMT-Y10>` greyscale format.
+Each pixel is 16-bit cell, with actual data stored in the 10 LSBs
+with values in range 0 to 1023.
+The six remaining MSBs are padded with zeros.
+
+
+The second plane provides 16-bit per-pixel Depth data arranged in
+:ref:`V4L2-PIX-FMT-Z16 <V4L2-PIX-FMT-Z16>` format.
+
+
+**Frame Structure.**
+Each cell is a 16-bit word with more significant data stored at higher
+memory address (byte order is little-endian).
