How audio watermarking technology works?
BARC is using audio watermarking technology, which is accurate, has auto recognition, and is future proof. Civolution has helped BARC create the audience measurement system.
Broadcasters have spent over Rs 100 crore for audio watermarking the channel feeds.
As of now, it has over 295 channels watermarked, while it will be monitoring spots on over 350 channels.
Audio watermarking solution is a platform-agnostic technology that captures video content consumption on all platforms. It is an encoding process that involves inserting an inaudible audio watermark into the content at the broadcaster’s end from where the signal will play out. The watermark has a time stamp, programme ID and a channel ID on it.
The moment a viewer switches on a particular channel and watches a show, the audio watermarking technology will immediately retrieve it through the code inserted into the content. The technology is also capable of tracking time-shifted and device-shifted viewing. Thus, if a viewer records a show on their digital video recorder (DVR) and watches it later, the watermarking technology will detect it.
