1. A method for operating a digital media renderer to reduce power consumption in a Digital Living Network Alliance (DLNA) network, the method comprising:
- receiving media content from a digital media server via a Wireless Local Area Network (WLAN);
establishing a control state based on the received media content;
controlling the power of at least one of a communication connection device and a display according to the control state of the received media content;
determining whether a buffering operation is in progress;
determining whether the digital media renderer also performs functions of a digital media player;
transitioning the WLAN, when it has been determined that a buffering operation is not in progress and that the digital media player functions are not performed by the digital media renderer, to a power save mode; and
disconnecting the WLAN, when it has been determined that a buffering operation is not in progress and that the digital media player functions are performed by the digital media renderer,wherein the digital media renderer comprises the communication connection device.

9. A method for operating a digital media server to reduce power consumption in a Digital Living Network Alliance (DLNA) network, the method comprising:
-
determining whether there is a user operation; determining whether a digital media renderer or a digital media player is in a connection state with a Wireless Local Area Network (WLAN); notifying the user of the WLAN state when it is determined that the digital media renderer or the digital media player is not in a connection state with the WLAN; and terminating the connection if the digital media renderer or the digital media player is not in the connection state or if there is no command from the digital media renderer or the digital media player for a predetermined time, wherein the digital media server turns off a display when there is no user operation. - View Dependent Claims (10, 11)

12. A method for operating a digital media server to reduce power consumption in a Digital Living Network Alliance (DLNA) network, the method comprising:
-
determining whether at least one digital media renderer or digital media player are in a connection state; notifying a user of the connection state of the at least one digital media renderer or the digital media player if at least one digital media renderer or digital media player is not in the connection state; transmitting digital media content, via a Wireless Local Area Network (WLAN), to the digital media renderer or the digital media player; and transitioning the WLAN to power save mode when the digital media content transmission is complete. - View Dependent Claims (13)

14. A method for reducing power consumption in a Digital Living Network Alliance (DLNA) network, the method comprising:
-
controlling the power of a display according to a control state of media content received from a digital media server; disconnecting the power of a communication connection device after completion of buffering the received media content when the communication connection device performs the functions of a digital media player; converting the communication connection device to a power save mode after completion of buffering the received media content when the communication connection device does not perform functions of a digital media player; and disconnecting the power of the communication connection device after displaying a pop-up window to a user, when the communication connection device is disconnected from the DLNA network. - View Dependent Claims (15, 16)

17. A system for reducing power consumption in a Digital Living Network Alliance (DLNA) network, the system comprising:
-
a Wireless Local Area Network (WLAN); a digital media renderer for controlling the power of a display according to a control state of media content received from a digital media server, for disconnecting the power of a communication connection device or converting the communication connection device to a power save mode after completion of buffering the received media content, and for interrupting the power of the communication connection device after displaying a pop-up window to a user when the communication connection device is disconnected from the WLAN; and a digital media server for determining whether the digital media renderer is in a connection state with the WLAN, for terminating the connection if the digital media renderer is not in the connection state, for determining whether there is a user operation of the digital media renderer, and for turning off a connected display when there is no determined user operation. - View Dependent Claims (18, 19)
