Abstract: A system and method for providing information about broadcasted content is provided. A synchronization server receives requests for information about content being broadcasted, such as a song being broadcasted by a radio station. The request can be issued by a listener of the radio station using his or her cellular telephone, a portable communications device, or a local computer. The time of the request is used to query a database of a music server associated with the radio station, to retrieve song title, artist name, and album name corresponding to the song currently being played by the radio station. Information about the song is then transmitted to the listener, whereupon the user can perform other tasks associated with the song, such as obtaining lyrics to the song, ordering tickets to events by the artist of the song, downloading ring tones, downloading the song, accessing a streamed version of the song, etc.

Abstract: A system and method for providing single-action multi-source presets for vehicle entertainment systems.

Abstract: Aspects of the invention buffer user preferred radio content on a radio system by monitoring the content on multiple channels in case a user desires to record one of the monitored channels.

Abstract: A radio receiver (10) can be tuned selectably in a first mode to radio stations broadcasting in the 87.5 to 108.0 MHz FM2 band and in a second mode to event radio broadcasts on preset frequencies at least one of which is outside that band. A pair of push-buttons (20,22) can be operated to change the reception frequency to which the receiver is tuned. When the first mode is selected, the push-buttons can be used to tune the receiver to any desired frequency in the FM band and/or to the frequency of any desired signal being received in the FM band. When the second mode is selected, the push-buttons can be used to tune the receiver only to any one of the preset event radio frequencies. When the user wishes to change between listening to a broadcast in the FM band and listening to an event radio broadcast outside the first band, they therefore do not need to scan between the event radio frequency and the frequency of the other broadcast.

Abstract: Single processing of the first channel search using the analog broadcasting tuner enables not only analog broadcasting channel to be detected but also the existence of digital broadcasting channel to be estimated. Furthermore, the acquisition of information transmitted on a digital broadcasting channel can be made apart from the first channel search when the channel is selected (received) or when the second channel search is performed. As a result, the first channel search (overall channel search) can be efficiently completed in a short time. In the second channel search for acquiring the digital broadcasting information, the number of physical channels to be searched is decreased by limiting to the number of the estimated channels. Accordingly, overall channel search which also acquires the digital broadcasting information is efficiently completed in a short time.
