Patent number: 11973577Abstract: In some examples, one or more processors configured by executable instructions may receive an audio signal and data to embed in the audio signal. For example, the data may be received dynamically from one or more data sources. The one or more processors may embed the received data in real time into the audio signal as embedded data based at least in part on controlling a phase angle of a selected frequency component of the audio signal. For instance, the embedded data may include at least one of text, a bar code, a quick response code, an image, a uniform resource locator (URL), or multimedia content. Additionally, the one or more processors may send the audio signal with the embedded data over a network to a plurality of electronic devices that include respective decoders for extracting the embedded data from the audio signal.Type: GrantFiled: September 23, 2021Date of Patent: April 30, 2024Assignee: ADORI LABS, INC.Inventors: Viswanathan Iyer, Kartik Parija, Andrew Cole

Patent number: 11848030Abstract: 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.
