1. A method for maintaining and broadcasting frame numbers in a digital system, the digital system monitoring a frame number controller through a central controlling unit to broadcast a new frame number of a next data frame, the method comprising the steps of:

  • the frame number controller obtaining the new frame number during a transmission period of a current data frame;

    broadcasting information related to the new frame number to frame number receivers installed in operational components of the digital system; and

    generating a frame boundary signal when each frame number receiver completely receives the new frame number, so the corresponding operational component can start using the new frame number.
