Abstract

The invention enables a user to obtain a document associated with the program content of a video signal. Coded data on a surface is read by a sensing device which generates indicating data which is a request for the document. A computer system receives the indicating data from the sensing device and extracts document identity data from the video signal, in order to retrieve the document.

Claims

1. A method of obtaining a document associated with a video signal using a computer system, a sensing device and coded data on a surface, wherein:

the sensing device is operable to sense the coded data and generate indicating data indicative of a request for the document; and

,

the computer system is operable to extract document identity data identifying the document from the video signal;

the method comprising the steps of;

placing the sensing device in an operative position relative to the surface for generating the indicating data using at least some of the coded data;

providing the computer system with the indicating data for extracting the document identity data;

identifying the document; and

retrieving the document.

2. The method of claim 1 including the further step displaying the document.

3. The method of claim 1 including the further step of printing the document.

4. The method of claim 1 in which the video signal is derived from at least one video playback device.

5. The method of claim 4 in which the playback device is one of:

a cassette-based video player, and a disk-based video player.

6. The method of claim 1 in which the video signal is derived from at least one video transmission.

7. The method of claim 6 in which the video transmission is one of:

a broadcast television transmission, a cable television transmission, a satellite television transmission, and an Internet video transmission.

8. The method of any one of claims 1 to 7 in which the video signal has an analogue format.

9. The method of any one of claims 1 to 7 in which the video signal has a digital format.

10. The method of claim 1 in which the coded data is indicative of an identity of a region of the surface and of a plurality of reference points of the region, and the indicating data is indicative of the identity of the region and a position of the sensing device relative to the region.

11. The method of claim 1 in which the document identity data is extracted from at least one data channel of the video signal.

12. The method of claim 11 in which the data channel is one of:

a caption data channel, a text data channel, and an extended data channel.

13. The method of claim 1 including the further steps of:

receiving, from the sensing device, user identity data indicative of an identity of the user;

identifying, using the user identity data, a user profile; and

customizing, using the user profile, the document.

14. The method of claim 1 in which the coded data is substantially invisible to the unaided human eye.

15. A system for enabling a user to obtain a document associated with a video signal, the system comprising:

a surface with coded data disposed on it;

a sensing device operable to sense at least some of the coded data and generate indicating data indicative of a request for the document when placed in an operative position relative to the surface;

a receiver for receiving the indicating data from the sensing device;

a decoder for extracting document identity data indicative of an identity of the document, from the video signal; and

a processing means operable to identify and retrieve the document.

16. The system of claim 15 which includes a display device for displaying the document.

17. The system of claim 15 which includes a printer for printing the document.

18. A printer for printing a document associated with a video signal, the printer comprising:

a receiver for receiving indicating data indicative of a request for the document;

a decoder for extracting document identity data indicative of an identity of the document from the video signal;

a network interface; and

a processor for transmitting the indicating data and the document identity data to a server and via the network interface, and receiving the document from the server via the network interface; and

a printhead for printing the document.
