Testing Lip Sync Issues with the SEVEN Generator

3/17/2021

Metadata (met·a·da·ta): A set of data that describes and gives information about other data
How could that little word (metadata) cause havoc for so many Audio/Video manufacturers and integrators trying to line up the audio and video signal? Why? Because our industry has gone beyond traditional 2 channel, or 6 channel, or even 8 channels of audio. Dolby Atmos and DTS HD are perfect examples of audio signals that rely on metadata to distribute audio through many channels. This invisible code runs alongside the audio signal that tells your audio products to distribute the specific sound to a specific channel; this code is metadata. 

Why would metadata cause lip sync issues?
When dealing with metadata, it takes time to decode the signal, and this can cause delays in your audio delivery. You may find your audio signal is coming in after your video. This is a new problem as integrators have always had the opposite problem, audio coming before the video and needing to delay the audio to line it up. How many of the tools you use to line up that audio have a video delay option? Almost none!

​Testing your products to see how they react with different types of audio and video combinations will allow you to deliver a superior installation or product to your customer. The Murideo method enables you to test these signals via HDMI, ARC, or even the HDMI 2.1 specification feature eARC. 

The Murideo SEVEN Generator is a scientifically accurate audio video testing device that allows you to select thousands of combinations of signals, including Dolby Atmos audio and HDR resolutions. As you test your product with various signals, you can measure the lip sync down to the millisecond, allowing you to make adjustments as needed.
