Abstract

The invention relates to a multimedia device, which detects at least one information item in an audio and/or video data stream processed by the multimedia device, saves the detected information items as a function of a weighting consisting of the time of occurrence of an information item and at least one selection criterion and displays follow-up information relating to the information item selected by a user on an output unit of the multimedia device.

Claims

1. A multimedia device for detecting at least one information item in an audio and/or video data stream processed by the multimedia device, said device comprising:

at least one memory configured for saving a detected one or more of said at least one information item according to a mathematical function evaluated on a weighted average that weighs a time of occurrence of a respective one of said detected one or more against a value to which at least one selection criterion is applied in making a selection; and

an output unit configured for presenting follow-up information relating to an item from among said one or more saved that has been selected by a user.

2. A multimedia device as claimed in claim 1, configured for drawing up and aligning, with one another, a first list (3) of said one or more information items detected in the audio and/or video data stream and a second list (4) of information items present in relation to the follow-up information.

3. A multimedia device as claimed in claim 2, configured for including in the first list (3) information items whose respective probabilities of occurrence is less than a limit value and whose respective time of occurrence in the audio and/or video data stream is recorded.

4. A multimedia device as claimed in claim 1, configured for searching, for follow-up information, at least one information source (2), such that, in event of no follow-up information being found in a first of said at least one information source, a further one of said at least one information source is searched.

5. A multimedia device as claimed in claim 4, configured for presenting, to the user, follow-up information in accordance with an information source in which the follow-up information to be presented is found.

6. The multimedia device of claim 1, configured such that said making a selection decides whether said respective one is saved in said saving.

7. The multimedia device of claim 6, wherein said value relates to said respective one.

8. The multimedia device of claim 1, wherein said value relates to said respective one.

9. The multimedia device of claim 1, wherein said weighted average also weighs a current time against said value.

10. The multimedia device of claim 1, wherein said stream is at least part of a television broadcast, said time of occurrence corresponding to time of occurrence within the broadcast.

11. A method of presenting follow-up information, comprising:

detecting at least one information item in an audio and/or video data stream processed by the multimedia device;

saving a detected one or more of said at least one information item according to a mathematical function evaluated on a weighted average that weighs a time of occurrence of a respective one of said detected one or more against a value to which at least one selection criterion is applied in making a selection; and

presenting follow-up information relating to an item from among said one or more saved that has been selected by a user.

12. The method of claim 11, wherein said making a selection decides whether said respective one is saved in said saving.

13. The method of claim 12, wherein said value relates to said respective one.

14. The method of claim 11, wherein said value relates to said respective one.

15. The method of claim 11, wherein said stream is at least part of a television broadcast, said time of occurrence corresponding to time of occurrence within the broadcast.

16. A network having at least one multimedia device for detecting at least one information item in an audio/video data stream processed by the multimedia device, comprising:

at least one memory configured for saving a detected one or more of said at least one information item according to a mathematical function evaluated on a weighted average that weighs a time of occurrence of a respective one of said detected one or more against a value to which at least one selection criterion is applied in making a selection; and

an output unit configured for presenting follow-up information relating to an item from among said one or more saved that has been selected by a user.

17. The network of claim 16, configured such that said making a selection decides whether said respective one is saved in said saving.

18. The network of claim 17, wherein said value relates to said respective one.

19. The network of claim 16, wherein said value relates to said respective one.

20. The network of claim 16, wherein said stream is at least part of a television broadcast, said time of occurrence corresponding to time of occurrence within the broadcast.
