How to read the tables:
The tables indicate how many data in pixels or quadlets (4bytes) are going to be transferred
per cycle for certain formats and modes and framerates.
Remember that everything in the IEEE1394 transfer is arranged in cycles, which last 125 µs.
Example: Camera: XCD-SX900, B/W; 7,5 Frames/s 1280 x 960 Pixel:
Please read: Format_2 Mode_2:
One line of 1280 pixels giving 1280 bytes or 320 quadlets (q) needs to be transferred per 125
µs.
Notes: There are modes which are not yet supported by existing camera models!
The cameras tell what formats and modes they support.
For instance, currently there is no SXGA camera which is able to run with 15 frames/s, just
because of lack of appropriate CCD-sensor at the time the camera was designed.
