GEOGRAPHICALLY INDEPENDENT DETERMINATION OF SEGMENT BOUNDARIES WITHIN A VIDEO STREAM

摘要

A method for creating an announcement stream for a geographic region is provided. The method receives, at a designated computer system, characterizing metadata for a first audio/video stream; analyzes a second audio/video stream to obtain characterizing metadata for the second video stream; compares, with the computer system, the characterizing metadata for the first video stream to the characterizing metadata for the second video stream to generate offset data; and calculates timing information corresponding to segment boundaries for the second video stream using the offset data.

主权项

1. A system for processing video stream data, comprising:
a marking station, configured to parse a reference video stream and to store data for the reference video stream, wherein the reference video stream comprises a plurality of video frames; and a comparison station, configured to receive reference video stream data, parse and store data for a video stream of interest, compare the reference video stream data to data for the video stream of interest, determine a plurality of segment boundaries for the video stream of interest based upon the comparison, and transmit announcement data comprising at least the determined plurality of segment boundaries to a plurality of video services receivers.
