Patent ID: 7283965

Claim:
The method for automatically measuring, monitoring, and switching signals for audio satellite broadcasts of program content in AC-3 standard format to be transmitted as AES-3 signal bit streams, said audio satellite broadcasts containing meta data, variable dependent upon said program content comprises: determining a predetermined count at which each packet in the AES-3 bit stream is to arrive, disenabling a response to receipt of the packet to avoid outputting the data in the packet if it is received before said predetermined count has lapsed from receiving the start of a packet, in an AES-3 signal bit stream generated by an original source of said program content for delivery to program content receivers by a direct broadcast satellite system, said direct broadcast satellite system having an uplink system, said uplink system operable to multiplex, modulate, encode and add conditional access information to said AES-3 bit stream; detecting if disruption occurs while packet is being received, by said uplink system; accepting the packet of AC-3 information for enabling output after a predetermined time period plus the predetermined count from which the last packet started, if a disruption has been detected, and determining whether said last packet comes within 10 milliseconds after an AC-3 packet was predicted to have arrived, and accepting said last packet as a trigger to provide a valid output in response to said detection.
