System and method to provide out-of-band broadcast trigger synchronization and communication to insertion devices

摘要

A cue message detection synchronizer that provides an out-of-band cue message to downstream content insertion devices. The cue message detection synchronizer receives a first data stream corresponding to a network feed, receives a second data stream corresponding to a provider feed, receives at least one cue message associated with the first data stream, compares the first data stream to the second data stream to determine a data stream offset, and generates cue message comprising one or more of: (i) the determined data stream offset, and (ii) a timestamp associated with the generated cue message and modified by the determined data stream offset. In this way, a location within a synchronized provider stream can be provided to downstream content insertion devices.

1. A method comprising:
receiving a first data stream corresponding to a network feed; receiving a second data stream corresponding to a provider feed; comparing the first data stream to the second data stream to determine a data stream offset, wherein comparing the first data stream to the second data stream to determine the data stream offset includes: creating a first perceptual hash of a first element in the first data stream; creating a second perceptual hash of a second element in the second data stream; determining a closeness of match between the first perceptual hash and the second perceptual hash; and generating the data stream offset if the determined closeness of match between the first perceptual hash and the second perceptual hash is greater than a predetermined closeness of match threshold, wherein the data stream offset corresponds to a difference between a first timestamp associated with the first element and a second timestamp associated with the second element; and generating a cue message, wherein the generated cue message includes one or more of: (i) the determined data stream offset, and (ii) a timestamp associated with the generated cue message and modified by the determined data stream offset.
