1. A signal source detection and selection system for detecting and selecting a signal source for a display apparatus having a plurality of signal input interfaces configured to receive a plurality of input signals from a plurality of signal sources, comprising an input interface scanner, an interface selector, a signal processor, and an output terminal;

  • wherein the input interface scanner is configured to scan each of the plurality of signal input interfaces and determine whether at least one signal input interfaces receives input signals;

    the interface selector, coupled to the input interface scanner, is configured to select a signal input interface as a selected signal input interface, and gate an input signal from the selected signal input interface to the signal processor;

    the signal processor, coupled to the input interface selector, is configured to process the input signal from the selected signal input interface to generate a processed signal; and

    the output terminal is configured to output the processed signal;

    wherein at least two signal input interfaces receive input signals;

    the interface selector is configured to select a signal input interface having a highest priority according to a priority table out of the at least two signal input interfaces as the selected signal input interface, the priority table ranking the plurality signal input interfaces by priority; and

    gate an input signal from the selected signal input interface to the signal processor; and

    wherein the interface selector comprises a priority setter for adjusting priority associated with the plurality signal input interfaces in the priority table.
