In a known manner, the broadcast station 10 broadcasts a series of audio works, referred to as the play-list 12, including in this example Song114 and Song216, each having its digital content, including a digital signal identifying the work being broadcast. The works, such as songs, are broadcast for real-time listening during receipt of the broadcast as is known in the broadcast industry.
Any digital radio device adapted for receiving the broadcast content may be used. This invention is preferably used with mobile devices, such as satellite radio receiver unit 34 (or other digital radio receiver) within vehicle 22. The satellite radio receiver unit 34 receives the broadcast content utilizing satellite signal antenna 26, which provides the received signal to the satellite radio receiver unit 34 in a known manner. The satellite radio receiver unit 34 may either be a separate unit adapted for use with an audio unit, such as the audio unit 32 or may be integrated to perform all of the functions of receiving the satellite radio signal and convention vehicle audio functions, and further may include known telematics functions. For examples including telematics units, GPS or other vehicle locating functions are included as well as any known telematics function). In the example shown in
The satellite radio receiver unit 34 processes the digital satellite radio signal broadcast by the broadcast station 10 and transmits that signal to the audio unit 32 for play of the selected station through the vehicle audio system speakers, represented schematically by speaker 38. Stations may be selected by one or more buttons 28 associated with the satellite radio receiver unit 34 or one or more buttons 30 associated with the vehicle's audio unit 32.
An operator input is provided, for example a button 28, or one or more of the buttons 30, to receive an input from a user of the vehicle 22 indicating that the user chooses the song or work currently being broadcast as a desired work. As explained below, the desired work is to be stored in a digital library within the memory of the satellite radio receiver unit 34 or the audio unit 32.
Upon receipt of the user input indicating user choice of the broadcast work, the satellite radio receiver unit 34 stores a signal identifying the work to which the user is currently listening. This signal may be a digital identification signal broadcast with the work, or some other signal that allows the satellite radio receiver unit 34 to recognize a subsequent broadcast of the same work.
This method can be used with works currently under copyright ownership for which license to download is required. In this example, the user input is taken in as a request under a user sale or licensing program for copyrighted works, such as popular music. The type of purchase program, for example, fixed fee per work, variable fee per work, fixed monthly or yearly fee for all works downloaded to the unit, is the choice of the system designer and business conditions arranged with the copyright owner(s) and/or clearing house(s) 50.
The request for purchase is transmitted to a service center 48. The service center 48 may be any facility suitable for tracking purchase requests and billing for downloaded works. In a preferred example, the purchase request is transmitted by a transceiver 36 with the mobile unit to the service center 48. One example for transmitting the request is to use the mobile telephone or radio network represented by tower 40 and cloud 44. Another example for transmitting the request is through a home computer 42 utilizing a short-range wireless transceiver function within transceiver 36. In this example, when the vehicle is away from the home computer (i.e., the user is driving it and it is not near the user's home), the purchase requests are maintained in the satellite radio receiver unit 34 until the vehicle 22 arrives in proximity of the home computer 42 to allow the short-range communication to occur. The home computer 42, then contacts the service center 48 utilizing the Internet 46, a telephone line or other available connection.
The service center 48 logs the request, and in a preferred example, sends a reply to the satellite radio receiver unit 34 acknowledging the request and enabling recording and playing of the work. The acknowledgment signal may help ensure that unauthorized use of the work does not occur. But it is understood that in systems where the acknowledgment signal is utilized, it may occur before or after recording, because either way the system may prevent playback of the work until receipt of the acknowledgment signal.
The service center 48 tabulates requests and transmits them through any suitable connection 54 to the broadcast station 10. Broadcast station 10 may make use of the information of requests to judge the popularity of songs, but more importantly for purposes of this invention, to ensure that songs that are requested are scheduled for subsequent broadcast so that satellite radio receiver unit 34 can complete the download of the work. In this example, a commercial arrangement between the broadcaster and the clearinghouse 50 might include a distribution fee paid to the broadcaster for sale or license of the work to the user.
Once the user request is made, the satellite radio receiver unit 34 monitors the content broadcast from broadcast station 10. This monitoring may be done using a low power consumption mode enabling active monitoring even when the vehicle 22 is not in use, but so as not to drain the vehicle battery. For examples in which this invention is implemented in a satellite digital radio system, the satellite radio receiver unit 34 may monitor all stations broadcast, and when the subsequent broadcast of the work is made, the satellite radio receiver unit 34 records the digital content of the work, and adds it to the user's play list. While this example assumes the play list function is within satellite radio receiver unit 34, it is understood that this function (including storage of the works in memory and selective playback thereof), may be done in the vehicle audio unit 32, or a combined unit that performs the satellite radio receiver function, the audio unit functions, and in some examples, telematics functions.
The storage of the work during subsequent broadcast may be accomplished by assembly the digital content as broadcast through the satellite radio system. The assembly reverses the effects of multiplexing or interleaving techniques, which causes the work to be segregated into data packets for broadcast. These data packets may then be aggregated at the satellite radio receiver unit 34. It may also be desirable for the satellite radio receiver unit 34 to reformat the data before storage, but such choices are left to the system designer.
The works stored in the satellite radio receiver unit 34 (or the audio unit 32, or if implemented, a combined unit (not shown)) are available for selective playback at the request of the user. Any known form of input/output function may be utilized for selective playback, including buttons 28, 30, which include associated display(s) (not shown). Alternatively, a voice user interface may be implemented in which the microphone 24 acts as input for voice commands, that are recognized and utilized to navigate through a menu provided by audio playback through the speakers 38 or through a visual display.
