Abstract

A content insertion system helps digital media providers insert replacement content (e.g., localized commercials) at precisely the right places in the video streams delivered to downstream players. Specifically, with frame accuracy, the system inserts content insertion triggers into the delivered video streams. From a source video input, the system determines the trigger positions at which insertion triggers exist with reference to house timecode. The system then locates the corresponding trigger positions in the output video stream with reference to a framecount of frames generated by a digital encoder. The system inserts corresponding content insertion triggers into the delivered video stream when it locates the corresponding trigger positions.
