Abstract

To allow teleshopping to be performed quickly and reliably via the television network, receivers (3) are equipped with smart card readers (4), and the transmitter (2) sends information which is processed in the smart cards by means of the viewers'"'"' control devices (6). The result of this process is displayed on the screen and communicated later to the transmitter. This result allows the viewers'"'"' reactions to be authenticated.

Claims

1. A method for instantaneous confirmation of viewer'"'"'s reactions in relation to television programs implemented in a television network including a transmitter and a plurality of receivers, wherein at least half of the receivers are equipped with smart card readers, comprising the steps of:

sending a least one piece of information for allowing authentication of a viewer'"'"'s reaction via said transmitter to said plurality of receivers during a time lapse in which viewers are likely to react to a program;

receiving said at least one piece of information at said plurality of receivers equipped with smart card readers;

processing said at least one piece of information sent by said transmitter in accordance with data stored in respective said smart cards at said plurality of receivers; and

producing a second piece of information as a result of said processing in accordance with said data stored in respective said smart cards, wherein said second piece of information identifies a particular viewer and authenticates the particular viewer'"'"'s reaction in relation to a television program.

2. The method according to claim 1, further comprising the step of communicating said second piece of information to said transmitter.

3. The method according to claim 1, wherein the authentication of the viewer'"'"'s reactions is performed at defined instants.

4. The method according to claim 1, wherein the information sent by the transmitter contains data identifying the program being viewed, and the date.

5. The method according to claim 4, wherein the data item allowing the authentication of the viewer'"'"'s reaction also allows the authentication of the viewer'"'"'s identity.

6. The method according to claim 4, wherein the data item allowing authentication of the viewer'"'"'s reactions may vary with time.

7. The method according to claim 1, wherein the information sent by the transmitter comprises a data item used to select specific viewer categories.

8. The method according to claim 1, wherein the information sent by the transmitter is included in the lines not used for video frame image transmission.

9. The method according to claim 1, wherein the method is used for teleshopping.

10. The method according to claim 1, wherein the method is used for television games.

11. The method according to claim 1, wherein the method is used for surveys.

12. The method according to claim 1, wherein the method is used for betting.

13. The method according to claim 1, wherein the method is used for lotteries.

14. A device for the instantaneous confirmation of viewer'"'"'s reactions in relation to television programs, comprising:

a television network transmitter; and

a plurality of receivers each equipped with a smart card reader, wherein the transmitter produces authentication data in relation to program content.

15. The device according to claim 14, wherein said authentication data contain data to identify program content and the date.

16. The device according to claim 14, wherein each said smart card reader includes means to exchange information via a smart card and means to control display of data developed by the smart card operating with the reading device.
