Abstract

Incorporating interactive media into a playlist allows for media, operable to play automatically without a prompt after being loaded, to be loaded into a playlist and played from the playlist without overlapping playback with other media in the playlist. Incorporating interactive media into a playlist involves employing a playlist, a media wrapper, a media control, and a media player to preroll media, immediately stop playing the prerolled media while other media is playing, signal that media has finished playing in order to seamlessly begin playing the next media in the playlist.

Claims

1. A computer-implemented method comprising:

receiving a playlist at a media player stored in memory and coupled to a processor, referencing a first media segment and a second media segment, the second media segment comprising an interactive media segment and operable to play automatically without a prompt after being loaded into an interactive media presentation control, the media player being configured to only present one media segment through a user interface at a time;

presenting the first media segment via the user interface;

prerolling the second media segment, wherein prerolling the second media segment comprises;

loading at least a predetermined minimum portion of the second media segment into a buffer for the interactive media presentation control before the presenting of the first media segment is complete; and

immediately postponing presentation of the second media segment, the immediately postponing facilitates prevention of overlapping playback with the first media segment;

receiving an event from the interactive media presentation control indicating that the presenting of the first media segment is finished;

receiving a loading complete event from the interactive media presentation control indicating that the second media segment has been completely loaded; and

immediately presenting the second media segment via the user interface after receiving the event and the loading complete event, the immediately presenting facilitating a seamless transition from the first media segment to the second media segment.

2. The computer-implemented method as recited in claim 1 wherein the postponing playback comprises issuing a stop command to a control.

3. The computer-implemented method as recited in claim 1 wherein the postponing playback comprises stopping a timer associated with presenting the second media segment.

4. The computer-implemented method as recited in claim 1 further comprising in response to receiving the loading complete event, prerolling a third media segment.

5. The computer-implemented method as recited in claim 1 wherein the second media segment is further operable to issue a custom event.

6. The computer-implemented method as recited in claim 5 wherein the custom event references a third media segment to be played in response to the custom event.

7. The computer-implemented method as recited in claim 1 further comprising receiving an end of playback event from the second media segment.

8. A computer-implemented method comprising:

parsing a playlist of media segments at a host application stored in memory and coupled to a processor comprising a media player having at least one reference to an interactive media segment operable to play continuously and a media presentation control operable to play the interactive media segment, the media player configured to only present one media segment at a time;

prerolling the interactive media segment in the media presentation control;

immediately stopping playback of the interactive media segment when it is not a first media segment in the playlist, the immediately stopping playback for preventing overlapping playback with a preceding media segment;

playing the interactive media segment in an interface of the media player after playback of the preceding media segment is complete and the prerolling is complete; and

receiving a media segment event from the media presentation control indicating that the playing of the interactive media segment has finished.

9. The computer-implemented method as recited in claim 8 further comprising:

stopping playback of the interactive media segment; and

playing a subsequent media segment in the playlist.

10. The computer-implemented method as recited in claim 8 wherein the playlist comprises an Advanced Stream Redirector (ASX) file.

11. The computer-implemented method as recited in claim 8 further comprising issuing to the host application a host-recognized event corresponding to the media segment event.

12. The computer-implemented method as recited in claim 11 wherein the media segment event comprises an EndOfPlayback event and the host-recognized event comprises a WMPEndOfPlayback event.

13. The computer-implemented method as recited in claim 8 wherein the media segment event comprises a custom event.

14. The computer-implemented method as recited in claim 8 further comprising:

playing a first media segment prior to the interactive media segment; and

buffering the interactive media segment in memory prior to completion of the first media segment.

15. The computer-implemented method as recited in claim 14 further comprising:

receiving a buffer progress indication from the control, the buffer progress indication indicating that a predetermined minimum portion of the interactive media segment has been buffered;

issuing an EndOfBuffering event to the host application.

16. The computer-implemented method as recited in claim 15 wherein the predetermined minimum portion is 100% of the interactive media segment.

17. The computer-implemented method as recited in claim 15 wherein the predetermined minimum portion is less than 100% of the interactive media segment.

18. The computer-implemented method as recited in claim 15 further comprising:

receiving a buffer complete indicator from the control indicating that 100% of the interactive media segment has been buffered;

issuing an EndOfStreaming event to the host application.

19. One or more computer-readable storage media, storing processor-executable instructions that, when executed on a processor, perform acts comprising:

instantiating an events wrapper associated with a first interactive media segment created using vector-based graphics animation techniques and operable to play continuously;

initializing a control operable to playback both the first interactive media segment and a non-interactive media segment;

hosting the control in a portion of a user interface;

buffering the first interactive media segment prior to completion of playback of a previous media segment, the previous media segment comprising a second interactive media segment or the non-interactive media segment;

immediately postponing presentation of the first interactive media segment in order to prevent overlapping playback with the previous media segment; and

receiving notification from the control when the previous media segment has completed playback.

20. The one or more computer-readable storage media as recited in claim 19 wherein the method further comprises:

receiving an end of buffering event from the control when the first interactive media segment has finished buffering; and

playing the first interactive media segment after the previous media segment completes playback and the end of buffering event is received.

21. The one or more computer-readable storage media of claim 20 wherein the method further comprises playing a later media segment after receiving notification that the first interactive media segment has completed playback.

22. A system comprising:

memory and a processor;

a media control module, stored in the memory and executable on the processor, operable to

parse a playlist of media segments at a host application stored in memory and coupled to a processor comprising a media player having at least one reference to an interactive media segment operable to play continuously and a media presentation control operable to play the interactive media segment, the media player configured to only present one media segment at a time;

preroll the interactive media segment in the media presentation control;

immediately stop playback of the interactive media segment when it is not a first media segment in the playlist, the immediately stopping playback for preventing overlapping playback with a preceding media segment;

play the interactive media segment in an interface of the media player after playback of the preceding media segment is complete and the prerolling is complete; and

receive a media segment event from the media presentation control indicating that the playing of the interactive media segment has finished; and

a playlist module, stored in the memory and executable on the processor, having one or more references to media segments to be played in an order presented.

23. A system as recited in claim 22 further comprising an events wrapper module, stored in the memory and executable on the processor, operable to receive an end of buffering notification from the media control module and issue a corresponding end of buffering notification to the host application module.

24. A system as recited in claim 22 wherein at least one of the referenced media segments comprises mixed media.

25. A system as recited in claim 22 wherein the playlist module comprises an event name associated with an event media segment to be played when a referenced media segment issues an event having the event name.

26. A system as recited in claim 25 wherein the playing of the media segment is postponed at least in part by stopping a timer that sends timer ticks to the media control for advancing playing of the media segment.
