20110041154 | Content Recognition and Synchronization on a Television or Consumer Electronics Device - An audio portion of content, such as an audio stream, is associated with a multimedia program. A server receives an audio fingerprint and a program identifier from a network and associates the audio fingerprint with an audio identifier. A request packet including the program identifier is transmitted over the network to request program guide information associated with the program identifier. The program data including the program guide information is received from the network and metadata associated with the audio identifier and the program data are transmitted onto the network. A user device initiates a request for the metadata by using an audio fingerprint and the program identifier. | 02-17-2011 |
