Abstract: A system for distinguishing a digital signal in a received serial bit stream signal, and for displaying data represented by the distinguished digital signal is disclosed. The system is contained in a single console. The bits represent data in an original digital signal having a predetermined bit rate, a predetermined number of bits per word, a predetermined number of words per frame, and a predetermined number of frames per subframe, with there being a predetermined synchronizing code word in each frame for defining the frame. The system includes a processing network for processing the received signal to reconstruct the bits, to recognize the code word from the recognized bits, and to define the frames in response to recognition of the code word to thereby distinguish a digital signal having the predetermined number of bits per word, the predetermined number of words per frame, and the predetermined number of frames per subframe.
