  • the user can then listen to the track by selecting the Music option from the application menu of Figure 4, and as described below. If a chosen broadcast selection involves information which must be conveyed by the user to a third party, such as the auto insurance quote ad in Figure 6, the user can press the CALL key and the third party will be dialed using the cell phone 36 and the number stored in the ad, whereby the user can carry on a conversation with the advertiser.

This audio signal is converted to digital form by the audio circuits 82 as described above, and transmitted to the host 12. The host computer can then process this audio signal through pattern recognition software and compare it with audio signals then being aired by stations within the user's location. The audio signals can be easily obtained from the individual radio station web sites on the internet, which generally include streaming audio corresponding to their broadcast signal. Such audio pattern recognition has been use for many years to track radio broadcasts, as described in U.S. Patent No. 4,843,562.

While the above descriptions have assumed the broadcast receiver is remote from the terminal 14, it is contemplated that one or more broadcast receivers (and/or a GPS receiver) 26 can be incorporated into the housing of the terminal 14 or the phone 36. If, at Figure 4, the user selected Music as the application, the terminal 14 would be configured to be able to select and receive streaming audio, preferably encoded in the MP3 format, from the host 12. Again, the audio may be stored in the user's section of the memory 40, and customized playlists created.
  • the decoder 88 is used to decode and provide the audio signals for listening via speakers or headphones. Because there is no storage of the entire music selection at the terminal (only a small volatile buffer is included in the MP3 decoder for streaming), it is extremely unlikely that the user will be able to make illegal digital copies of the music selection. As indicated above, purchased music using the system 10 can be stored in the memory 40 for future listening. Also, it is contemplated that the host 12 can download the lyrics of a song for display in synchronism with the music, where the lyrics appear on the screen 60 as the song is being played, as further disclosed in my issued U.S. Patent 5,408,686.

If the selection includes a web address, the user can either press the MARK key to bookmark the address and the ad in the host memory 40, and press the LINK key to be connected to the web page immediately. Note that ads can also include coupon offers such as the one for gasoline in Figure 7.

  • a variety of billing options are available to the system operator for the present invention. For example, the user can be charged for reading a book prior to downloading any of the text, or the user can be billed on a pay-as-you-read basis, where he is just billed for the displayed pages. In addition to billing the user using a credit card, the user can be automatically billed to his cell phone bill, eliminating the need for pre-registration or the transfer of sensitive credit information.
  • the host 12 which can identify the user by telephone number, communicates with the billing system of the communications network 42 to complete the billing transaction. Because the user obtains data from the host in a rather continuous fashion, it is important that the terminal 14 be able to communicate with the host 12, even in areas where cell phone service is not available. For example, in an airplane, passengers are usually required to turn off all RF emitting devices during flight, which is also a time when users would like to access reading material. To overcome this problem, it is envisioned that every airplane will be equipped with an on-board server connected via cables to each seat, whereby the server is connected via a satellite link to the internet and acts as a LAN for the passengers.
  • the terminal 14 may be connected, via the USB to such a LAN 37 (in place of the phone 36) so that system operation is not interrupted during flight.

  • the terminal 14 would also be equipped with an on-board server connected via cables to each seat, whereby the server is connected via a satellite link to the internet and acts as a LAN 28 for the passengers. Since RF emissions are generally not a problem on ships, and the passengers are mobile, the terminal 14 would communicate with this LAN 28 via BlueTooth.

  • this phone ID data has been made available to both the host (from the network 42) and to the terminal 14 (from the phone 36), so that it is a simple matter to use such ID for encryption and decryption of all data communications between host and terminal.
  • the use of a smart card can also provide a secure user specific key for data security.
  • Yet another security technique is to have the host embed user traceable "watermark" data bits into downloaded data, which are not displayed but which survive any illegal copying of such data. In the event an illegal copy is found, the watermark can identify the source for further legal measures. Also, the BlueTooth communications between the terminal and other devices would be encoded to provide a level of security as anticipated by the BlueTooth standards committee.
