Abstract: Methods and systems configured to embed data representing content output by at least one device for downstream content recognition or other downstream processes. For example, a device operates one or more media data embedding components configured to embed information regarding the output media, such as audio or image content. The embedding component is trained to embed information for a subset of known downstream processes with some known processes deliberately held out from the training. Among other benefits, this approach can help reduce over customization of the embedding component and allow more information to preserved by the component for purposes of downstream operations that may yet be configured.
