Abstract
A method for detecting errors on an audio/video (A/V) data stream in a data service network includes providing multicast components operably coupled to each other via respective links for transmitting the A/V data stream to a user and for defining at least one multicast tree. The method further includes generating a state information signal indicative of a number of errors on the A/V data stream for at least one of the links and at least one of the plurality of multicast components. The method further includes determining the cumulative number of errors on the A/V data stream that are indicative of the number of errors for the at least one of the links and the at least one of the plurality of multicast components in the multicast tree in response to the state information signal.
