Method and system for message collision avoidance

摘要

A system that incorporates the subject disclosure may include, for example, receiving first and second audio input signals from first and second communication sources. First and second emergency alert system messages are respectively identified from each of the first and second audio input signals. A temporal overlap is detected between a portion of the first emergency alert system message and the second emergency alert system message. In response to detection of the temporal overlap, a relative delay is applied between the first and second audio output signals. First and second audio output signals are generated including the first and second messages adjusted by the relative delay, such that the first and second emergency alert system messages in the first and second audio output signals are non-overlapping. Other embodiments are disclosed.

1. A method comprising:
receiving, by a system comprising a processor, a first audio input signal from a first communication source and a second audio input signal from a second communication source; detecting, by the system, within the first audio input signal, first digitally encoded data indicative of a first emergency alert system message; detecting, by the system, within the second audio input signal, second digitally encoded data indicative of a second emergency alert system message; providing, by the system, information indicative of the detecting of the first and second digitally encoded data; detecting, by the system, a temporal overlap of a portion of the first emergency alert system message of the first audio input signal and the second emergency alert system message of the second audio input signal, wherein the detecting of the temporal overlap is based on the information indicative of the detecting of the first and second digitally encoded data; generating, by the system, a first audio output signal including the first emergency alert system message and a second audio output signal including the second emergency alert system message; and applying, by the system, in response to the detecting of the temporal overlap, a relative delay between the first audio output signal and the second audio output signal, such that the first emergency alert system message in the first audio output signal and the second emergency alert system message in the second audio output signal are non-overlapping.
