Abstract

Disclosed is a method for receiving playable media stored in a server by user equipment having a motion sensor and playing the media according to the motion of the user equipment. The method includes the steps of (a) designating a part of the media as a first receiving area by the server and transmitting it to the user equipment; (b) changing a playback area, in which the media are played, according to the motion of the user equipment and playing a part of the media; and (c) requesting by the user equipment that the server provide a second receiving area, which is a part of the media including the playback area, when the playback area is outside the first receiving area of the media, receiving the second receiving area, and playing the media. When media stored in the server are to be played initially, it is unnecessary to download the entire media, so that the user equipment can play the media more efficiently.

4. The method as claimed in claim 1, wherein the media have at least one playback reference axis for defining a playable area so that the media can be played in the playable area, the playback reference axis being a reference axis for moving and changing the playback area of the media, and in step (b), a motion of the user equipment corresponding to a direction of the playback reference axis is detected to move and change the playback area of the media according to the motion of the user equipment and to play the media in the playback area.

5. The method as claimed in claim 1, wherein the second receiving area is designated to contain the playback area based on information regarding a memory of the user equipment.

6. The method as claimed in claim 4, wherein the media have three-dimensional stereoscopic information, and the playback reference axis comprises x-axis as a reference of movement direction along the x-axis, y-axis as a reference of movement of direction along the y-axis, and z-axis as a reference of movement of direction along the z-axis.

7. The method as claimed in claim 4, wherein the media have two-dimensional stereoscopic information, and the playback reference axis comprises x-axis as a reference of movement direction along the x-axis, y-axis as a reference of movement direction along the y-axis, and z-axis for indicating a scale of enlarged playback of the media.

8. A system for receiving playable media stored in a server by user equipment having a motion sensor and playing the media by a motion of the user equipment, wherein

the server receives a first receiving area transmission request of the user equipment, designates a partial area of the media as a first receiving area, and transmits the first receiving area to the user equipment,

the user equipment receives the first receiving area from the server, changes a playback area, the media being played in the playback area, according to a motion of the user equipment, and plays media corresponding to the playback area, and when the playback area is outside the first receiving area of the media, the user equipment requests the server to provide a second receiving area, the second receiving area being a part of media containing the playback area, receives the second receiving area, and plays the media.

9. The system as claimed in claim 8, wherein the server designates the first receiving area based on information regarding a memory of the user equipment, and transmits the first receiving area to the user equipment.

10. The system as claimed in claim 8, wherein, when there is a history of the media played by the user equipment, the server receives recent playback area information from the user equipment, the recent playback area information being information regarding an area recently played by the user equipment, designates the first receiving area based on the recent playback area information, and transmits the first receiving area to the user equipment.

11. The system as claimed in claim 8, wherein the second receiving area is designated to contain the playback area based on information regarding a memory of the user equipment.
