Through the above procedure, the multimedia service is moved to the second terminal [S250]. The server 320 refers to the characteristic information and the information on the playback position, and streams the contents of the format optimized for the second terminal 330 among the various formats of the same multimedia from the corresponding position, and the second terminal The playback unit 334 of 330 receives and plays the transmitted streaming data.

At this time, the playback unit 334 plays the content based on the multimedia information of the first terminal 310 received from the reception unit 333, thereby maintaining the same playback environment in the first terminal 310. . That is, when the content is requested to be played from the first terminal 310 to the second terminal 330, the contents are played back from the position where the first terminal 310 was played, and other volume, subtitle setting, aspect ratio, etc. The regeneration environment can be kept intact.

Meanwhile, the playback unit 334 of the second terminal 330 determines whether to execute the multimedia service first [S260]. That is, it is determined that the multimedia service is first performed when the playback command signal is first received from the receiver 330 or the generator 331 to the playback unit 334, and the streaming data of the content received from the server 320 is executed. Is executed first and foremost in the second terminal 330 [S270].

For example, assuming that the first terminal 310 is a digital TV and the second terminal 330 is a portable terminal, the multimedia service is changed from the first terminal 310 to the second terminal 330. When the mobile terminal, which is the second terminal 330, receives the priority play command signal, the mobile terminal preferentially executes the multimedia service. On the other hand, when the first terminal does not receive a play command signal from the mobile terminal 330, the mobile terminal typically performs a general service and receives a multimedia service provided by a digital TV through a separate input of a user. Will play.

On the contrary, assuming that the first terminal 310 is a mobile terminal and the second terminal 330 is a digital TV, the multimedia service is changed from the first terminal 310 to the second terminal 330. In case that the first playback command signal is received from the digital TV, which is the second terminal 330, the digital TV preferentially executes the multimedia service.

Therefore, when the digital TV is turned on, the multimedia service being played on the portable terminal can be immediately played. On the other hand, when the digital TV that is the second terminal 330 does not receive a priority play command signal, when the digital TV is turned on, the broadcast channel when the power is turned off is reproduced through a separate input by a user. The multimedia service provided by the mobile terminal is played back.
