Abstract

Cloud computing based video service and playing methods are provided. The video service method of a cloud computing server includes transmitting a requested video to a terminal in a streaming manner when the terminal requests play of the video, stopping the streaming transmission of the video and storing a stopped time point of the play in a user database when the terminal stops the play of the video, and transmitting the video beginning with a frame of the video at the stopped time point to the terminal or another terminal having requested play of the video in the streaming manner when the terminal or the other terminal requests the play of the video, in which the terminal or the other terminal having requested the play receives and plays the video beginning with the frame of the video at the stopped time point in a real-time manner.

Claims

1. A video service method of a cloud computing server, the method comprising:

transmitting a requested video to a terminal in a streaming manner when the terminal requests play of the video;

stopping the streaming transmission of the video and storing a stopped time point of the play in a user database when the terminal stops the play of the video; and

transmitting the video beginning with a frame of the video at the stopped time point to the terminal or another terminal having requested play of the video in the streaming manner when the terminal or the other terminal requests the play of the video,

wherein the terminal or the other terminal having requested the play receives and plays the video beginning with the frame of the video at the stopped time point in a real-time manner.

2. The method of claim 1, further comprising determining a cut-off time point as the stopped time point and storing the determined cut-off time point in the user database when connection with the terminal is cut-off

3. The method of claim 2, further comprising sending an inquiry to the terminal or the other terminal having requested the play to inquire whether the terminal or the other terminal selects to view the video from the beginning or continue to view the video from the stopped time point.

4. The method of claim 3, further comprising:

receiving a start time point of play with respect to the video from the terminal and storing the received start time point of play in the user database; and

transmitting the video beginning with a frame at the start time point to the terminal or other terminal having requested the play of the video in a streaming manner when the play of the video is requested from the terminal or the other terminal

5. The method of claim 1, further comprising:

periodically receiving a current playing time point of the video from the terminal;

recording the current playing time point in the user information; and

determining the current playing time point as the stopped time point and storing the determined current playing time point in the user database when connection with the terminal is cut-off

6. A video service method of a cloud computing server, the method comprising:

receiving a request for play of a video from a terminal;

checking a user database of the terminal; and

transmitting the video beginning with a frame at a stopped time point in a streaming manner when the video was stopped while previously being played,

wherein the terminal receives and plays the video beginning with the frame at the stopped time point in a real-time manner.

7. The method of claim 6, further comprising storing the stopped time point corresponding to a time point when the terminal stops the play of the video in the user database when the terminal stops the play of the video while streaming transmission.

8. The method of claim 7, further comprising determining a cut-off time point when connection with the terminal is cut-off while streaming transmission and storing the determined cut-off time point in the user database as the stopped time point.

9. The method of claim 8, wherein the transmitting of the video comprises:

sending an inquiry to the terminal to inquire whether the terminal selects to a view the video from the beginning or continue to view the video when the stopped time point of the video is stored in the user database; and

transmitting the video beginning with the frame at the stopped time point in the steaming manner when the terminal selects to continue to view the video.

10. A method for playing a video of a terminal, the method comprising:

receiving the video from a cloud computing server and playing the received video in a real-time manner;

stopping play of the video according to a request of a user; and

transmitting the stopped time point of the play to the cloud computing server,

wherein the cloud computing server transmits the video beginning with a frame at the stopped time point to the terminal or another terminal in a steaming manner when the terminal or the other terminal requests the video.

11. The method of claim 10, further comprising periodically transmitting a current playing time point of the video to the cloud computing server,

wherein the cloud computing server transmits the video beginning with a frame of the current play time point in a streaming manner when the terminal or other terminal again requests to play the video after connection with the terminal is cut-off

12. A cloud computing server for providing a video service, the cloud computing server comprising:

a memory for storing a user database;

a communication unit for communicating with one or more terminals; and

the controller for controlling the memory and the communication unit, wherein

the controller controls to transmit a requested video to a terminal in a streaming manner when the a first request to play the video is received from the terminal, controls to stop the streaming transmission of the video and store a stopped time point of the play in the user database when an indication is received from the terminal that the playing of the video by the terminal has stopped, and controls to transmit the video beginning with a frame of the video at the stopped time point to the terminal or another terminal from which a second request to play the video in the streaming manner is received.

13. A cloud computing server for providing a video service, the cloud computing server comprising:

a memory for storing a user database;

a communication unit for communicating with one or more terminals; and

the controller for controlling the memory and the communication unit, wherein,

the controller, when a request to play a video is received from a terminal, checks the user database of the terminal, and controls to transmit the video beginning with a frame at a stopped time point in a streaming manner when the video was stopped while previously being played.

14. A terminal for playing a video by using a video service, the terminal comprising:

a memory;

a communication unit for communicating with a cloud computing server; and

the controller for controlling the memory and the communication unit, wherein

the controller, when the video is received from a cloud computing server, controls to play the received video in a real-time manner, controls to stop play of the video according to a request of a user, and controls to transmit the stopped time point of the play to the cloud computing server.
