How we Collect Data

  1. 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.
  2. The watermark is broadcast along with the content.
  3. As viewing details are recorded by the BAR-O-meters, so are the watermarks.
  4. The raw data is cleaned, merged with the channel, program, language and broadcast schedule details. Universe Estimates are applied to get viewership data.

This gives content owners unprecedented visibility into when and where their content is broadcast, who has viewed it, etc.

As the watermark is part of the content, any attempt to destroy or remove it will also ruin the quality of the material in which it is embedded. This increases the integrity of the data generated by BARC India’s ratings.
