Interoperable AV Sync Systems in the SMPTE 22TV Lip Sync AHG: Content-Fingerprinting-Based Audio-Video Synchronization

An end-to-end interoperable content fingerprint-based audio-video synchronization system is described, including an audio-video fingerprinting technology overview and current status of the standardization process in the SMPTE 22TV Lip Sync Ad Hoc Group (AHG). The system is based on the audio-video fingerprinting technology currently submitted to the SMPTE 22TV Lip Sync AHG by Miranda Corp. The particular type of signatures are implemented and embedded in Zeitera Corp.'s file-based workflow, and in Miranda's realtime SDI-based audio-video synchronization equipment, showing signatures being captured by either vendor's system and providing results through either vendor's application management flow. An example of successful collaboration on an interoperable, mixed-vendor solution that can handle both compressed audio-video files and realtime SDI audio-video input is highlighted.
