Abstract

A system for synchronized streaming of media includes a memory and a processor. The processor is operable to establish connections with user applications executing on a plurality of user devices. The processor is further operable to identify a list of user tracks associated with one of the plurality of users stored in the memory. The processor is further operable to stream tracks from the list of user tracks to each of the plurality of user applications synchronously such that each of the plurality of user applications plays the same tracks at approximately the same time. The processor is further operable to receive at least one comment from one of the computing devices. The processors is further operable to send the at least one comment to a remainder of the plurality of computing devices for display through the user applications.

Claims (80)

1. A method comprising:

at a server having a memory and a processor:

establishing connections with user applications executing on a plurality of user devices;

receiving a request from one of the user applications to start a streaming session;

starting a streaming session in response to the request from the one of the user applications;

identifying a list of user tracks stored on the memory selected by a user associated with the one of the user applications;

sending a notification to at least one other user application that the streaming session has started;

receiving a request from the at least one other user application to join the streaming session;

adding the at least one other user application to the streaming session;

adding tracks selected by another user associated with the at least one other user application to the list of user tracks;

streaming tracks from the list of user tracks to each of the plurality of user applications synchronously such that each of the plurality of user applications plays the same track at approximately the same time;

receiving at least one advance track request from one of the user devices;

scheduling an operation to stream a next track in the list of user tracks in response to the at least one advance track request;

generating a timing key associated with the at least one advance track request, wherein the timing key is indicative of the time at which the at least one advance track request was received;

verifying whether the timing key is the most recent timing key generated:

if the timing key is the most recent timing key generated, executing the scheduled operation to stream the next track;

if the timing key is not the most recent timing key generated, canceling the scheduled operation to stream the next track;

receiving at least one comment from one of the user devices; and

sending the at least one comment to a remainder of the plurality of user devices for display through the user applications.

2. The method of claim 1 , wherein the tracks are video.

3. The method of claim 1 , wherein the tracks are music.

4. The method of claim 3 , further comprising:

causing to display a synchronized graphical visualization of the music on each of the plurality of user applications;

causing to display a plurality of effects widgets on each of the plurality of user applications, wherein each of the plurality of effects widgets represents a unique visual effect, and wherein a user selects a desired visual effect by placing the corresponding effects widget into the synchronized graphical visualization; and

in response to a selection of a visual effect by a user, updating the synchronized graphical visualization of the music to reflect the chosen visual effect on the plurality of user applications.

5. The method of claim 1 , wherein streaming tracks is accomplished via loose synchronization.

6. The method of claim 1 , wherein streaming tracks is accomplished via tight synchronization.

7. A system comprising:

a memory; and

a processor operable to:

establish connections with user applications executing on a plurality of user devices;

receive a request from one of the user applications to start a streaming session;

start a streaming session in response to the request from the one of the user applications;

identifying a list of user tracks stored on the memory selected by a user associated with the one of the user applications;

send a notification to at least one other user application that the streaming session has started;

receive a request from the at least one other user application to join the streaming session;

add the at least one other user application to the streaming session;

add tracks selected by another user associated with the at least one other user application to the list of user tracks;

stream content from the list of content to each of the plurality of user applications synchronously such that each of the plurality of user applications plays the same content at approximately the same time;

schedule an operation to stream a next track in the list of user tracks in response to the at least one advance track request;

generate a timing key associated with the at least one advance track request, wherein the timing key is indicative of the time at which the at least one advance track request was received;

verify whether the timing key is the most recent timing key generated:

if the timing key is the most recent timing key generated, execute the scheduled operation to stream the next track;

if the timing key is not the most recent timing key generated, cancel the scheduled operation to stream the next track;

receive at least one comment from one of the user devices; and

send the at least one comment to a remainder of the plurality of user devices for display through the user applications.

8. The system of claim 7 , wherein the tracks are video.

9. The system of claim 7 , wherein the tracks are music.

10. The system of claim 9 , wherein the processor is further operable to:

cause to display a synchronized graphical visualization of the music on each of the plurality of user applications;

cause to display a plurality of effects widgets on each of the plurality of user applications, wherein each of the plurality of effects widgets represents a unique visual effect, and wherein a user selects a desired visual effect by placing the corresponding effects widget into the synchronized graphical visualization; and

in response to a selection of a visual effect by a user, update the synchronized graphical visualization of the music to reflect the chosen visual effect on the plurality of user applications.

11. The system of claim 7 , wherein streaming tracks is accomplished via loose synchronization.

12. The system of claim 7 , wherein streaming tracks is accomplished via tight synchronization.

13. A computer program product comprising:

a computer readable non-transitory storage medium having computer readable program code embodied thereon, the computer readable program code configured for:
