HERE'S HOW WE COLLECT DATA
FOR YOUR analytical needs_

01

EMBED AUDIO WATERMARKS

Audio Watermarking embeds audio watermarks in video content prior to upload and broadcast. These watermarks are not audible to the human ear, but can easily be detected and decoded using dedicated hardware or software.

02

PLAYOUT & BROADCAST

The watermark is broadcast along with the content.

03

BAR-O-METERS

As viewing details are recorded by the BAR-O-meters, so are the watermarks.

04

VIEWERSHIP DATA

The raw data is cleaned, merged with the channel, program, language and broadcast schedule details. Universe Estimates are applied to get viewership data.
