Disambiguation of fingerprint-based channel multiple matching using steganographically encoded data as a basis

摘要

This disclosure provides disambiguating fingerprint-based channel multiple matching based on using steganographically encoded data. A fingerprint matching server or other entity may detect a channel multiple matching scenario by determining that query fingerprints representing media content rendered by the content presentation device each match reference fingerprints representing multiple channels. In view of the detected channel multiple matching scenario, the content presentation device stegano to the media content of the channel the content presentation device renders in order to use the extracted channel identification information to determine which channel the content presentation device renders. Channel identification information extracted by the content presentation device from the graphically encoded watermark may be provided. Identifying the channel being rendered may facilitate channel specific actions, such as detecting opportunities for content modification in the identified channel and enabling the content presentation device to prepare and perform the associated content modification.
