title: The output stream format of Kinect
body: <p>What is the output stream format of Kinect cameras? For instance it is said like a conventional video, it is 640x480, 30 fps, 4 bytes for each pixel (3RGB+depth)? so 1 second of the raw stream will have 640x480x30x4 bytes. Is there any ways to provide a layered compression for the streams ?</p>
