  11 16-bit depth data with distance values at each pixel
  12

  14 Description
  15 ===========
  16
  17 This is a 16-bit format, representing depth data. Each pixel is a
  18 distance to the respective point in the image coordinates. Distance unit
  19 can vary and has to be negotiated with the device separately. Each pixel
  20 is stored in a 16-bit word in the little endian byte order.
  21
  22 **Byte Order.**
  23 Each cell is one byte.
