Abstract

A method for handling interference during the transmission of a chronological succession of digital images (I) from a sender (S) to at least one receiver (R), in which the images to be transmitted show the face of a Speaker at least intermittently, involves images in the chronological succession that are unable to be decoded, or unable to be decoded satisfactorily, on account of the interference being replaced by synthentic images (P) at the receiver. The synthetic images are produced using phonetic data (LD) that are or have been extracted from digital voice data (SD) for the Speaker by means of phonetic recognition, the digital voice data being or having been transmitted together with the digital image data (I).

Claims

1-12. -12. (canceled)

13. A method to handle errors during a transfer of a chronological sequence of digital images from a sender to at least one receiver, wherein the images to be transferred show the face of the speaker at least intermittently, comprising replacing one or more images of a chronological sequence that cannot be decoded due to an error, or cannot be decoded in a satisfactory manner, with one or more synthesized images on a receiver end or en route to the receiver, generating or selecting the images using sound data extracted using sound recognition from digital voice data of the speaker, and transferring digital voice data together with the digital images.

14. The method of claim 13, wherein a transfer error is a result of an intermittent reduction in an available data rate.

15. The method of claim 13, comprising generating or having generated at least one synthesized image on the receiver end.

16. The method of claim 13, comprising generating at least one synthesized image during the transfer.

17. The method of claim 13, comprising adding extracting sound data from the digital voice data on the receiver end during the transfer.

18. The method of claim 13, comprising maintaining a library of synthesized images of at least one speaker on the receiver end.

19. The method of claim 13, comprising generating at least one synthesized image on a transmission path between the sender and the at least one receiver.

20. The method of claim 19, comprising extracting sound data from the digital voice data on the transmission path during the transfer.

21. The method of claim 13, comprising adding a library of synthesized images of at least one speaker on a transmission path between the sender and the at least one receiver.

22. Communication equipment that handles errors during a transfer of a chronological sequence of digital images from a sender to at least one receiver, wherein the images to be transferred show the face of the speaker at least intermittently, by a method comprising replacing one or more images of a chronological sequence that cannot be decoded due to an error, or cannot be decoded in a satisfactory manner, with one or more synthesized images on a receiver end or en route to the receiver, generating or selecting the images using sound data extracted using sound recognition from digital voice data of the speaker, and transferring the digital voice data together with the digital images.

23. The communication equipment of claim 22, wherein said communication equipment extracts sound data from voice data.

24. The communication equipment of claim 22, wherein said communication equipment generates synthesized images from sound data and from digital image data to be transferred or received.
