    This is an error from the operating system describing a problem with the IEEE-1394 bus. Normally it means that there is not enough bandwidth available on the IEEE-1394 bus to support the video format and frame rate requested. There are several possible workarounds:
     
    1. Reboot the computer. This is often a transient problem that can be solved by a reboot.
    2. Make sure that no other devices are using the IEEE-1394 bus.
    3. Reduce the video resolution by specifying a different video format or reduce the requested frame rate.
     
    To learn more about the VideoFormat property type
    web([docroot,'/toolbox/imaq/videoformat.html'])
    at the MATLAB command prompt.
     
    To learn more about the FramesPerTrigger property, execute:
     
    web([docroot,'/toolbox/imaq/framespertrigger.html'])

    at the MATLAB command prompt.
