Abstract

Systems, methods, and computer program products for bidirectional control between two or more media players. A first media player is launched on a computer system either manually or automatically. A second media player is subsequently launched. Inter-process communication is established between the first and second media players. The second media player determines if the first media player is playing first media content. If the first media player responds affirmatively, the second media player sends a command via the inter-process communication to the first media player to stop playing. The first player responds to the request from the second player by stopping playback. The second media player then begins playback of a second media content. After the second media content stops playing, the second media player informs the first media player, and the first media player returns to playing the first media content.

Claims

1. A method for controlling media players operating on a computer system, the method comprising:

establishing an inter-process communication between a first media player and a second media player;

in the second media player, determining if the first media player is playing first media content using the inter-process communication;

if the first media player is playing the first media content, sending a command via the inter-process communication to the first media player to stop playing; and

starting playback of second media content on the second media player.

2. The method according to claim 1, further comprising:

in the first media player, after receiving the command from the second media player, stopping playback of the first media content.

3. The method according to claim 1, further comprising:

when the second media content stops playing, sending a begin playback command to begin playback of the first media content, from the second media player to the first media player via the inter-process connection.

4. The method according to claim 1, further comprising:

launching on the computer system the first media player;

starting playback of a first media content on the first media player, and

launching the second media player on the computer system.

5. The method according to claim 4, wherein launching the second media player occurs as the result of requesting a web page.

6. The method according to claim 5, wherein the second media player is embedded within the web page.

7. The method according to claim 4, wherein launching the second media player occurs as the result of user interaction with a web page.

8. The method according to claim 7, wherein the second media player is launched as the result of a script within the web page.

9. The method according to claim 8, wherein the script causes a container to be created, with the second media player being within the container.

10. The method according to claim 1, wherein the first media player is a stand-alone player.

11. The method according to claim 1, further comprising:

maintaining a priority among the media players; and

launching a third media player, the third media player;

establishing an inter-process communication with the first media player,

establishing an inter-process communication with the second media player, and

communicating with the first and the second media players through the connections to coordinate playback based upon the priority.

12. A computer program product comprising a tangible computer-readable medium for use with a computer system, the computer-readable medium having program code thereon for controlling playback of media content on a first media player, the computer code comprising:

computer code for establishing an inter-process communication with the first media player;

computer code for determining if the first media player is playing first media content;

computer code for sending a command via the inter-process communication to the first media player to stop playing if the first media player is playing the first media content; and

computer code for starting playback of a second media content.

13. The computer program product according to claim 12, further comprising:

computer code for sending a begin playback command to the first media player via the inter-process communication to begin playback of the first media content when the second media content stops playing.

14. The computer program product according to claim 13, wherein the first media player is embedded within a web page.

15. The computer program product according to claim 12, further comprising:

computer code for maintaining a priority among the media players; and

coordinating playback between the media players based upon the priority.

16. A system for controlling a media server, the system comprising:

a speaker;

a video display;

a first media player adapted to;

connect to the media server to control the reception of audio or visual data from the media server,

display audio or visual data retrieved from the media server on the speaker or video display, respectively, and

communicate with other media players using inter-process communication; and

a second media player adapted to;

display audio or visual data on the speaker or video display, respectively, and

communicate commands to the first media player, using inter-process communication, for directing the first media player to control the reception of audio or visual data from the media server.

17. The system according to claim 16, wherein the first media player is a standalone media player.

18. The system according to claim 16, wherein the first media player is embedded in a web browser displayed on the video display.

19. The system according to claim 16, wherein the second media player is a standalone media player.

20. The system according to claim 16, wherein the second media player is embedded in a web browser displayed on the video display.

21. The system according to claim 16, wherein the first media player is within a first computing device and the second media player is within a second computing device.

22. The system according to claim 16, wherein the first media player and the second media player are adapted to avoid simultaneous playback of audio on the speaker by communicating with each other using inter-process communication.

23. The system according to claim 16, wherein the first media player and the second media player are adapted to avoid simultaneous display of video data on the video display by communicating with each other using inter-process communication.

24. The system according to claim 16, wherein the reception of audio or visual data from the media server includes the reception of data according to a playlist, and the second media player is adapted to direct the first media player to select the next media in the playlist for playback, select the previous media in the playlist for playback, load the playlist, save the playlist, add media to the playlist, or remove media from the playlist.

25. The system according to claim 24, wherein the media server controls the playlist, and the second media player does not have permission to modify the playlist.

26. A method for controlling a media server, the method comprising:

in a first media player, connecting to the media server and requesting transmission of a stream of first media data;

in the first media player, receiving the stream of first media data and playing it;

in a second media player, using inter-process communication, sending the first media player a command to stop receiving the stream;

in the first media player, as a result of receiving the command, directing the media server to stop sending the stream; and

in the second media player, playing second media data.

27. The method according to claim 26, further comprising:

in the second media player, using inter-process communication, sending the first media player a second command to resume receiving the stream of first media data;

in the second media player, stopping the play of the second media data;

in the first media player, as a result of receiving the second command, connecting to the media server and requesting transmission of the stream of first media data; and

in the first media player, receiving the stream of first media data and playing it.

28. The method according to claim 27, wherein the second media player sends the second command in response to a user request.

29. The method according to claim 27, wherein the second media player sends the second command in response to reaching the end of the second media data during playback.

30. The method according to claim 27, wherein the second media player sends the second command in response to reaching a certain date or time during playback.
