Interoperable AV SYNC Systems in 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 audio-video fingerprinting technology overview and current status of the standardization process in SMPTE' 22TV Lip Sync AHG. The system is based on the audio-video fingerprinting technology currently submitted to the SMPTE 22TV Lip Sync AHG by Miranda Corporation. The particular type of signatures are implemented and imbedded in Zeitera Corporation' file based workflow, and in Miranda' real-time SDI-based audio/video synchronization equipment, showing signatures being captured by either vendor's system, and providing results through either vendors application management flow. The example of successful collaboration on an interoperable, mixed vendor solution that can handle both compressed audio/video files and real-time SDI audio/video input is highlighted.
