Method for synchronizing a rich media action with an audiovisual change, corresponding device and computer software, method for generating a rich media presentation and corresponding computer software

A computer program product embodied on a non-transitory computer readable medium, comprising:

• computer code for obtaining change information including a time tag associated with a time of a change to new audiovisual content in an audiovisual content stream;
• computer code for synchronizing an action in a piece of media content with the change, the synchronization comprising:
• computer code for converting the change information into a media event by comparing the time tag associated with the time of the change to the new audiovisual content with a current time stamp of a currently decoded and displayed image of the audiovisual content stream, and triggering the media event when the time tag associated with the time of the change to the new audiovisual content coincides with the current time stamp of the currently decoded and displayed image of the audiovisual content stream;
• computer code for detecting the media event by at least one media object of a media presentation, the media presentation including the new audiovisual content and the media content;
• and
• computer code for triggering the action in the media presentation on the basis of the detected media event.

A system comprising:

• a memory system;
• and
• one or more processing cores coupled to the memory system and that are each configured to:
• obtain change information including a time tag associated with a time of a change to new audiovisual content in an audiovisual content stream;
• synchronize an action in a piece of media content with the change, the synchronization comprising:
• convert the change information into a media event by comparing the time tag associated with the time of the change to the new audiovisual content with a current time stamp of a currently decoded and displayed image of the audiovisual content stream, and triggering the media event when the time tag associated with the time of the change to the new audiovisual content coincides with the current time stamp of the currently decoded and displayed image of the audiovisual content stream;
• detect the media event by at least one media object of a media presentation, the media presentation including the new audiovisual content and the media content;
• and trigger the action in the media presentation on the basis of the detected media event.
