Abstract

Apparatuses and methods related to a server, a multimedia apparatus and a control method thereof, are provided. More particularly, the apparatuses and methods relate to a server, a multimedia apparatus and a control method thereof which synchronously plays multimedia contents through a plurality of multimedia apparatuses. A multimedia apparatus includes: a communicator configured to be connected to a server; and a controller configured to transmit to the server a request to start playing a multimedia content, receive synchronization information from the server that is necessary for synchronously playing the multimedia content. The synchronization information from the server is determined on the basis of the play start request, and synchronously plays the multimedia content based on the received synchronization information.

Claims

1. A method of controlling a server, the method comprising:

receiving a request to start playing multimedia content from one of a plurality of multimedia apparatuses;

determining synchronization information necessary for synchronously playing the multimedia content between the plurality of multimedia apparatuses, based on a system clock of the server; and

transmitting to the plurality of multimedia apparatuses the determined synchronization information which corresponds to the system clock.

2. The control method according to claim 1, wherein the transmitting the determined synchronization information to the plurality of multimedia apparatuses comprises periodically transmitting the synchronization information that is determined based on the system clock.

3. The control method according to claim 1, further comprising receiving a late time and adjusting the system clock based on the late time, in response to one of the plurality of multimedia apparatuses being late in playing the multimedia content.

4. The control method according to claim 1, further comprising receiving a paused time and adjusting the system clock based on the paused time, in response to one of the plurality of multimedia apparatuses pausing playing the multimedia content.

5. The control method according to claim 1, further comprising receiving a play start time and adjusting the system clock based on the play start time, in response to one of the plurality of multimedia apparatuses starting play of the multimedia content after a pause.

6. The control method according to claim 1, further comprising receiving a skip time and adjusting the system clock based on the skip time in response to one of the plurality of multimedia apparatuses skipping the multimedia content.

7. The control method according to claim 1, further comprising receiving a request for stopping playing and stop playing the multimedia content according to the request, in response to one of the plurality of multimedia apparatuses stopping play of the multimedia content.

8. A server comprising:

a communicator configured to be communicably connected to a plurality of multimedia apparatuses; and

a controller configured to receive a request from one of the plurality of multimedia apparatuses to start playing multimedia content, determine synchronization information necessary for synchronously playing the multimedia content between the plurality of multimedia apparatuses, based on a system clock of the server, and transmit to the plurality of multimedia apparatuses the determined synchronization information which corresponds to the system clock.

9. The server according to claim 8, wherein the controller is configured to periodically transmit to the plurality of multimedia apparatuses the synchronization information that is determined based on the system clock.

10. The server according to claim 8, wherein the controller is configured to receive a late time and adjust the system clock based on the received late time, in response to one of the plurality of multimedia apparatuses being late in playing a multimedia content.

11. The server according to claim 8, wherein the controller is configured to receive a paused time and adjust the system clock based on the received paused time, in response to one of the plurality of multimedia apparatuses pausing the playing of the multimedia content.

12. The server according to claim 8, wherein the controller is configured to receive a play start time and adjusts the system clock based on the play start time, in response to one of the plurality of multimedia apparatuses starting playing of the multimedia content after a pause.

13. The server according to claim 8, wherein the controller is configured to receive a skip time and adjust the system clock based on the skip time, in response to one of the plurality of multimedia apparatuses skipping a multimedia content.

14. The server according to claim 8, wherein the controller is configured to receive a request to stop playing of the multimedia content and stops playing the multimedia content according to the request in response to one of the plurality of multimedia apparatuses stopping playing the multimedia content.

15. A method of controlling a multimedia apparatus, the method comprising:

transmitting to the server a request to start playing multimedia content;

receiving from the server synchronization information that is necessary for synchronously playing the multimedia content and determined by the server to correspond to the request to start playing the multimedia content; and

synchronously playing the multimedia content based on the received synchronization information.

16. The control method according to claim 15, wherein the receiving the synchronization information from the server comprises periodically receiving the synchronization information that is determined based on the system clock of the server.

17. The control method according to claim 15, further comprising transmitting a late time to the server in response to the playing of the multimedia content being late.
