Abstract

An arrangement (100) for distributing a content item, comprising a content provider (116) arranged for embedding extra information in a video portion of the content item and for making the content item with said embedded extra information available for reception by a rendering device (110), which comprises receiving means (111) for receiving the content item, decoding means (112) for decoding the extra information from the video portion, embedding means (113) for embedding the extra information in an audio signal (120), and rendering means (114) for rendering the audio signal (120).

Claims

1. A rendering device (110) comprising receiving means (111) for receiving a content item comprising at least a video portion, in which portion extra information is embedded, decoding means (112) for decoding the extra information from the video portion, embedding means (113) for embedding the extra information in an audio signal (120), and rendering means (114) for rendering the audio signal (120).

2. A rendering device (110) as claimed in claim 1, whereby the extra information is embedded in the video portion by means of a video watermark.

3. A rendering device (110) as claimed in claim 1, wherein the embedding means (113) are arranged for embedding the extra information in the audio signal (120) by means of an audio watermark.

4. A rendering device (110) as claimed in claim 1, whereby the audio signal (120) is an audio portion of the content item.

5. A rendering device (110) as claimed in claim 1, wherein the embedding means (113) are arranged for obtaining the audio signal (120) from a storage medium (118).

6. A rendering device (110) as claimed in claim 1, wherein the embedding means (113) are activated in response to a user action.

7. An arrangement (100) for distributing a content item, comprising a content provider (116) arranged for embedding extra information in a video portion of the content item and for making the content item with said embedded extra information available for reception by a rendering device (110) as claimed in any of the claims 1 to 6.

8. A computer program product (140) being arranged for causing a processor to execute the steps of receiving a content item comprising at least a video portion, in which portion the extra information is embedded, decoding the extra information from the video portion, embedding the extra information in an audio signal (120), and rendering the audio signal (120).
