synchronizing an action in a piece of media content with the change, the synchronization comprising:
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;
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
triggering the action in the media presentation on the basis of the detected media event.
2. The method according to claim 1 , wherein the change information including the time tag is received from a presentation server after being transmitted to the presentation server from a broadcast server, and the audiovisual content stream is received from the broadcast server, wherein the broadcast server is different than the presentation server.
3. The method according to claim 1 , wherein the change information includes action information representative of the action in the piece of media content.
4. The method according to claim 3 , wherein the action information includes at least one of a URN (“Uniform Resource Name”), a URI (“Uniform Resource Identifier”), and a URL (“Uniform Resource Locator”).
5. The method according to claim 1 , further comprising creating the media presentation, comprising:
triggering, by at least one audiovisual interface object or media interface object, the media event representative of the change in the audiovisual content stream;
creating the at least one media object suitable for detecting the media event;
activating the at least one media object upon detection of the media event
associating the action with the activation of the at least one media object.
6. The method according to claim 1 , wherein the change to the new audiovisual content includes a change between a first sequence and a second sequence, and the first sequence includes an advertisement sequence.
7. The method according to claim 6 , wherein the second sequence includes a film sequence.
8. The method according to claim 1 , wherein the change to the new audiovisual content includes a change of a channel and the change of the channel includes a change of source channel.
9. The method according to claim 1 , wherein the change to the new audiovisual content includes a change of a channel, and the change of the channel includes substituting images from a next channel for those of a previous channel in the audiovisual content stream.
10. The method according to claim 1 , wherein 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.
11. 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.
12. The computer program product according to claim 11 , wherein the computer program product is operable such that the change information including the time tag is received from a presentation server after being transmitted to the presentation server from a broadcast server, and the audiovisual content stream is received from the broadcast server, wherein the broadcast server is different than the presentation server.
13. The computer program product according to claim 11 , wherein the computer program product is operable such that the change information includes action information representative of the action in the piece of media content.
14. The computer program product according to claim 13 , wherein the computer program product is operable such that the action information includes at least one of a URN (“Uniform Resource Name”), a URI (“Uniform Resource Identifier”), and a URL (“Uniform Resource Locator”).
15. The computer program product according to claim 11 , further comprising creating the media presentation, comprising computer code for:
triggering, by at least one audiovisual interface object or media interface object, the media event representative of the change in the audiovisual content stream;
creating the at least one media object suitable for detecting the media event;
activating the at least one media object upon detection of the media event;
associating the action with the activation of the at least one media object.
16. The computer program product according to claim 11 , wherein the computer program product is operable such that the change to the new audiovisual content includes a change between a first sequence and a second sequence, and the first sequence includes an advertisement sequence.
17. The computer program product according to claim 16 , wherein the computer program product is operable such that the second sequence includes a film sequence.
18. The computer program product according to claim 11 , wherein the computer program product is operable such that the change to the new audiovisual content includes a change of a channel and the change of the channel includes a change of source channel.
19. The computer program product according to claim 11 , wherein the computer program product is operable such that the change to the new audiovisual content includes a change of a channel, and the change of the channel includes substituting images from a next channel for those of a previous channel in the audiovisual content stream.
20. 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;
