Abstract
Some examples include a computing device that receives media content to distribute to a plurality of electronic devices. The computing device may receive an indication of first data to relate to the media content for distribution to the plurality of electronic devices. A portion of the multimedia content may be decoded to enable a determination that the media content already has second data embedded in the media content. A psychoacoustic mask may be extracted from the media content and subtracted from the received media content to remove the embedded second data. The first data may be associated with the media content by either embedding third data in the media content, or by embedding the first data in the media content.
