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 system, comprising:

• means for obtaining change information including a time tag associated with a time of a change to new audiovisual content in an audiovisual content stream, where such change to the new audiovisual content includes one or more of a change of a channel and a change between an advertisement sequence and a film sequence, such that the time tag corresponds to a first image of the new audiovisual content including the one or more of the change of the channel and the change between the advertisement sequence and the film sequence;
• means for synchronizing an action in a piece of media content with said change, said synchronization comprising:
• means for converting said 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 said 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;
• means for detecting said media event by at least one media object of a media presentation, said media presentation including said new audiovisual content and said media content;
• and
• means for triggering said action in said media presentation on the basis of said detected media event.

A computer program product embodied on a non-transitory tangible medium that can be read by a computer, 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, where such change to the new audiovisual content includes one or more of a change of a channel and a change between an advertisement sequence and a film sequence, such that the time tag corresponds to a first image of the new audiovisual content including the one or more of the change of the channel and the change between the advertisement sequence and the film sequence;
• computer code for synchronizing an action in a piece of media content with said change, said synchronization comprising:
• computer code for converting said change information into a media event 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 said 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 said media event by at least one media object of a media presentation, said media presentation including said new audiovisual content and said media content;
• and
• computer code for triggering said action in said media presentation on the basis of said detected media event.
