New Lip Sync Indicator

We are currently developing a new video quality indicator (VQI) called Lip Sync VQI.

Its main purpose is to detect a lack of synchronisation between audio and video streams. This de-synchronization usually manifests itself as a speech signal following (or lagging) lips movement (thus the name Lip Sync).

The development process is realised in a close cooperation with our business partner. This ensures a final product meets industry-class requirements. At every stage we are testing a performance of the solution in a realistic environment. By doing so we make sure to keep in-line with initial assumptions and performance requirements.
