Patent ID: 8351517

Claim:
An electronic device comprising: a communication module configured to wirelessly transmit and receive signals via at least one of a first physical link and a second physical link, wherein power consumption for wireless transmission and reception of signals via the first physical link is lower than power consumption for wireless transmission and reception of signals via the second physical link; a first control module configured to establish the second physical link between the communication module and an external device, to transfer digital content data between the communication module and the external device via the second physical link, and to transmit a remote control signal to the external device via the second physical link; a link control module configured to disconnect the second physical link and to establish the first physical link between the communication module and the external device, when the transfer of the digital content data is stopped in response to the remote control signal; and a second control module configured to transmit a playback request signal to the external device via the first physical link, to disconnect the first physical link, and to re-establish the second physical link between the communication module and the remote device in order to resume the transfer of the digital content data, when a playback start event for starting playback of the digital content data is generated in a state in which the second physical link is disconnected.
