Today, even the simplest of processing equipment can have enough memory to delay video or audio a significant amount to introduce a human discernible lip-sync error - when the audio is not timed correctly to the action on the screen. Some system designs have the video and audio de-coupled from each other taking a separate path from source to destination, which becomes even more challenging to manage.
Managing audio and video timing in a broadcast environment can be a tedious and frustrating undertaking involving many man-hours of troubleshooting to determine where the audio and video are drifting in time. Evertz has recognized this globally common dilemma and has engineered IntelliTrak™ as the solution to monitor and correct lip sync error in real-time and within real program content.
IntelliTrak™ has been designed to accurately measure the lip sync error between the audio and video by analyzing the content at an origin point and then comparing that to a final destination point. IntelliTrak™ does not introduce any type of watermarking or flag insertion into the stream and therefore operates in a completely non-intrusive manner.
This technology can be applied to a number of Evertz products, including frame synchronizers, protection switches, multiviewers and many more!
IntelliTrak™ has been designed to blend into existing systems with minimal effort. There are several ways to implement IntelliTrak™ depending on the available infrastructure.
Effective when origin and destination points are connected to a common network.
Effective when origin and destination points are on independent networks or when origin is not connected to a network.
Effective when no network interface is available.
