Abstract

A teletext receiver receives and processes teletext in accordance with a personal profile set up at the receiver or received from a wireless device. The personal profile specifies a subset of the available teletext by page number, by keyword or by metadata. The teletext is stored in a buffer memory and compared with previously updated pages in a content memory to determine if the page has been updated. Updated page numbers are stored in a personal user interface set-up file so that the updated pages can be viewed on a receiver display. Alternatively, or in addition, the updated pages are sent to the wireless device so that a user can receive personalised teletext content based on one of a number of profiles stored at the receiver.

Claims

1. A method of personalising an information service associated with a television transmission, the information service providing content to a receiver, the method comprising:

creating a personal content profile, the profile defining a subset of the content;

storing the personal content profile;

receiving content from the service; and

processing the received content according to the stored profile.

2. A method according to claim 1, wherein the step of processing the received content comprises filtering the content to extract the defined subset of the content.

3. A method according to claim 2, wherein the receiver comprises a buffer memory and a content memory, the method comprising the steps of:

receiving the content into the buffer memory;

retrieving content from the buffer memory corresponding to information specified in the profile; and

comparing the retrieved content with data stored in the content memory to determine whether the content has been updated.

4. A method according to claim 3, comprising determining that the retrieved content has been updated when it is different from corresponding content stored in the content memory.

5. A method according to claim 3, comprising determining that the retrieved content has been updated when corresponding content does not exist in the content memory.

6. A method according to claim 3, wherein the information specified in the profile comprises a page number.

7. A method according to claim 3, wherein the information specified in the profile comprises at least one keyword.

8. A method according to claim 3, wherein the information specified in the profile comprises an item of metadata information.

9. A method according to claim 3, wherein the information specified in the profile comprises any combination of a page number, a keyword and an item of metadata information.

10. A method according to claim 3, further comprising storing the updated content in the content memory.

11. A method according to claim 3, further comprising updating a user interface set-up file with information identifying the updated content.

12. A method according to claim 11, further comprising displaying information content at the receiver based on the identifying information stored in the user interface set-up file.

13. A method according to claim 11, comprising displaying the information content by retrieving information content from the content memory corresponding to the identifying information.

14. A method according to claim 11, wherein the identifying information comprises a page number.

15. A method according to claim 3, further comprising generating alerts to alert a user that updated content exists.

16. A method according to claim 15, comprising generating alerts in accordance with information stored in the personal content profile.

17. A method according to any one of the preceding claims, comprising creating the profile at the receiver.

18. A method according to claim 17, further comprising sending the personal content profile to a wireless device remote from the receiver.

19. A method according to claim 1, comprising creating the profile at a wireless device remote from the receiver, storing the profile at the wireless device and transmitting the profile to the receiver.

20. A method according to claim 1, comprising storing the profile at the receiver.

21. A method according to claim 3, further comprising sending the updated content to a wireless device remote from the receiver and storing the updated content at the wireless device.

22. A method according to claim 21 comprising displaying the content at the wireless device based on the content stored at the wireless device.

23. A method according to claim 1, comprising identifying a user prior to permitting access to a personal content profile.

24. A method according to claim 1, wherein the information service is a teletext service.

25. A method according to claim 1, wherein the content includes text content.

26. A method according to claim 1, wherein the content includes picture content.

27. A method according to claim 1, wherein the content includes audio content.

28. A method according to claim 1, further comprising receiving content from the service in DVB-MHP format.

29. A method according to claim 1, further comprising receiving content from the service in markup language format.

30. Apparatus for receiving content from an information service associated with a television transmission, comprising:

means for creating a personal content profile, the profile defining a subset of the content;

means for storing the personal content profile;

means for receiving content from the service; and

means for processing the received content according to the stored profile.

31. Apparatus according to claim 30, further comprising a buffer memory and a content memory and means for comparing the contents of the buffer memory and the content memory to determine whether the content has been updated.

32. Apparatus according to claim 31, further comprising means configured to update the content memory with the updated content.

33. Apparatus according to claim 31, further comprising a personal user interface memory and means configured to update the personal user interface memory with information identifying the updated content.

34. Apparatus according to claim 30, further comprising means for displaying personalised content, said means including means for retrieving content from the content memory based on the identifying information in the personal user interface memory.

35. Apparatus according to claim 30, wherein the identifying information comprises page numbers.

36. Apparatus according to claim 30, further comprising means for transmitting the personalised content to a wireless device.

37. Apparatus according to claim 30, comprising a teletext receiver.

38. A wireless device for receiving personalised content from an information service associated with a television transmission, comprising:

means for creating a user-specific personal content profile, the profile defining a subset of the content;

means for transmitting the profile to a receiver, the receiver being configured to receive content from the information service and to personalise the received content in accordance with the profile, the wireless device further comprising;

means for receiving the personalised content from the receiver; and

means for displaying the personalised content.

39. A wireless device according to claim 38, further comprising a personal content memory for storing the received content.
