Abstract

A method and a system of interactive access on the telephone to information elements that have already been broadcast or are being broadcast from a set of sources. For this purpose, the system has a center for the digital recording and management of radio broadcast information elements, accessible through the switched telephone network by keying in a telephone number and the time at which the information to be listened to has been broadcast.

Claims

1. A method of deferred access to radio information elements broadcast by a radio broadcasting source, the method comprising the steps of:

receiving and digitizing the information elements broadcast by the source;

recording the information elements cyclically and continuously with temporal reference markers corresponding to broadcasting time slots;

determining the time slot of the recording in which any information element is located;

accessing the recorded information elements from a telecommunications terminal through a switched telephone network, the accessing step including

establishing a telephone call from the telecommunications terminal to the central processing unit by dialing a telephone number assigned to a central processing unit,

giving the source and time of the broadcast or a corresponding code of the information elements,

dedicating keys of a keypad of the telecommunications terminal to predetermined functions, and

interactively interrogating the central processing unit by pressing one of the dedicated keys, the telecommunications terminal transmitting requests corresponding to the predetermined functions in response to the pressing of the dedicated key;

reading and transmitting the information elements, the information elements being transmitted to the telecommunications terminal through the switched telephone network during the telephone call;

interrupting the reading and transmitting of the information elements when a request is received from the telecommunications terminal;

responding to the request during the interrupting step; and

receiving the information elements instantaneously on the telecommunications terminal.

2. The method of deferred access to radio broadcast information elements according to claim 1, wherein the predetermined functions are the functions of backward running, forward running and pausing with respect to a read information element.

3. The method according to claim 1, wherein the broadcasting source and time are given from the keypad of the telecommunications terminal.

4. The method according to claim 1, wherein the telecommunications terminal comprises a telephone and wherein the broadcasting source and time are given orally through the telephone.

5. The method according to claim 1, wherein the reading and transmitting step occur in real-time relative to the recording step.

6. A system of deferred access to radio broadcast information elements broadcast by a radio broadcasting source, the system comprising:

a center for receiving and recording broadcast information elements and for managing access to the information elements in read/write mode, the center being accessible through a switched telephone network, and the center including;

a radio broadcast receiver, the receiver being tuned to a broadcasting frequency corresponding to the broadcasting source,

a central management and processing unit, the central unit digitizing in real-time the information elements received by the receiver, and the central unit recording the information elements cyclically and continuously with temporal reference markers corresponding to broadcasting time slots, the central unit determining the time slot of the recording in which any information element is located, and the central unit recognizing and responding to interactive requests as the interactive requests are received;

means for receiving a telephone call through the switched telephone network and for transmitting during the telephone call the information elements requested; and

subscribers'"'"' equipment including a telecommunications terminal for

interactively interrogating the central unit by transmitting interactive requests to the central unit, and for

receiving the desired information elements through the switched telephone network during the telephone call.

7. The system of access according to claim 6, wherein the means for receiving and for transmitting comprises an answering machine, and wherein the answering machine sends pre-recorded voice messages and restores the requested information elements also in the form of voice messages.

8. The system of access according to claim 6, wherein the telephone terminal comprises a telephone having a voice frequency keypad.

9. The system of access according to claim 8, wherein the keypad comprises keys dedicated to predetermined functions.

10. The system of access according to claim 6, wherein the source is located outside the reception perimeter of the center and wherein the receiver is placed in the field of radiation of the source and is connected by transmission means to the center.

11. A system for accessing radio broadcast information elements from a broadcast source, the system comprising:

a center, the center including

a radio broadcast receiver, the receiver being tuned to a frequency corresponding to the frequency of the broadcast source,

a central processing unit, the central unit defining means

for digitizing in real-time the information elements received by the receiver,

for recording the information elements cyclically and continuously with temporal reference markers corresponding to broadcasting time slots,

for determining the time slot of the recording in which any information element is located,

for reading the information elements requested through the switched telephone network,

for interrupting the reading of the information elements when an interactive request is received,

for responding to the requests during the interruption; and

a telephone interface unit, the telephone interface unit defining means

for receiving a telephone call through a switched telephone network, and

for transmitting the information elements through the switched telephone network during the telephone call; and

a telecommunications terminal, the telecommunications terminal defining means

for transmitting the interactive requests to the central unit, and

for receiving the desired information elements through the switched telephone network during the telephone call.

12. The system according to claim 11, wherein the telecommunications terminal comprises a telephone having a voice frequency keypad.

13. The system according to claim 12, wherein the telephone interface unit further comprises means

for converting requests made by subscribers on the voice frequency keypad into digital signals, and

for expressing vocally an answer given by the central unit to the request.

14. The system according to claim 11, wherein the keypad comprises keys dedicated to predetermined functions.

15. The system of access according to claim 11, wherein the source is located outside the reception perimeter of the center, and wherein the receiver is placed in the field of radiation of the source and is connected by a transmitter to the center.

16. The system of access according to claim 15, wherein the transmitter comprises a digital link.

17. A method for the real-time access to radio information elements broadcast by a radio broadcasting source, the method comprising the steps of:

receiving and digitizing the information elements broadcast by the source;

recording the information elements cyclically and continuously with temporal reference markers corresponding to broadcasting time slots;

determining the time slot of the recording in which any information element is located;

accessing the recorded information elements from a telecommunications terminal through a switched telephone network, the accessing step including

establishing a telephone from the telecommunications terminal to the central processing unit call by dialing a telephone number assigned to a central processing unit, and

giving the source and time of the broadcast or a corresponding code of the information elements;

reading the recorded information elements and transmitting the information elements to the telecommunications terminal through the switched telephone network during the telephone call, the reading and transmitting step occurring in real-time relative to the recording step; and

receiving the information elements instantaneously on the telecommunications terminal.
