Method for distributing multimedia public warning alerts in a mobile telecommunications network, including: creating an alert message by an emergency authority computer in the network, the message including a textual message and a multimedia object; sending by a content distributor server parameters for a content delivery session; sending by the computer the created message to the server; sending by the computer a request for a cell broadcast message to a cell broadcast center in the network, the message including the textual message and content delivery session parameters; broadcasting by the cell broadcast center the message through a radio access network; receiving by mobile user equipment in the network the message through the radio access network; setting up by the multicast content distributor server a transparent IP multicast session between the server and at least some of the user equipment; sending the multimedia object though the session to the user equipment.

A multimedia device capable of providing notification information for each user in a standby mode is disclosed. The multimedia device according to one embodiment of the present invention comprises: a control unit entering the standby mode when the multimedia device is turned off; a notification information collection unit for collecting notification information from at least one of a broadcasting station, an external device, and an external server when the multimedia device has entered the standby mode; a sensing unit for acquiring user information and information of distance with the user when the multimedia device has entered the standby mode; and a display unit, wherein, when a user recognized on the basis of the acquired user information corresponds to a preset user, and when the acquired information of distance with the user corresponds to a preset distance value, the control unit activates a partial region of the display unit and displays, on the activated partial region, notification information corresponding to the recognized user from among the pieces of collected notification information.

A system and circuit for television power state control are disclosed. In one embodiment, a power management circuit communicatively controls television or set-top box components including a signal processing circuitry, a screen, and a visual indicator. The power management circuit selectively alternates the television between three states: powered ON/operating state (first state); power standby state (second state); and no/low power state (third state). Utilized with a television in a commercial or residential application, the system and circuit are employed to provide accelerated turn-on time to receive an image for user interaction, while providing sufficient control to maintain energy power savings.

A facility for transferring configuration information to a target media device is described. The facility receives in the target media device a copy of media device settings stored in a source media device distinct from the target media device in a first form in which they are used in the source media device. This copy of media device settings is received by the target media device via a route other than its visual user interface. The facility causes the received copy of media device settings to be transformed into a second form in which they can be used in the target media device. The facility then stores the media receiver settings in the second form in the target media device for use by the target media device.

The present disclosure provides a display device that includes an external input interface including an input port connected to a source device, and a processor configured to detect that a source device is connected through an unselected input port of a plurality of input ports, activate an external input interface corresponding to the unselected input port, perform a connection process between the source device and the external input interface, deactivate error detection operation between the source device and the external input interface, generate fake connection information for maintaining connection between the source device and the external input interface based on information input to the external input interface from the source device, and switch the external input interface to a standby mode.

An image transmission device including a content compression unit configured to compress an image signal, a wireless transmission unit configured to wirelessly transmit the compressed image signal to an image reception device, and a processor configured to switch a power mode of the image transmission device to a low power mode based on a determination that an image signal is not being received from an external source or that an ambient brightness at the image reception device is less than a preset brightness, and control the content compression unit to increase a compression rate of the image signal in the low power mode.

Disclosed herein are system, method, and computer program product embodiments for the detection of human presence in front of a plurality of sensors such as those of speakers and a device with a processor, such as a television. Data gathered from the plurality of sensors may be analyzed by the processor to determine if one or more humans are present proximate to the device. Based on the determined presence or absence of one or more humans, further actions including, inter alia, activating a sleep mode for the one or more humans, shutting off the device in a green mode, or alerting an owner-user to the presence of an intruder can be taken.

Disclosed herein are system, method, and computer program product embodiments for the detection of human presence in an energy efficient manner using a plurality of sensors such as those of a battery-powered device such as a television remote, and a device with a processor, such as a television. Data gathered from an initial television WiFi radio scan, or an initial low-powered detection scan from the television remote, may be analyzed by the processor to determine a potential presence of one or more humans are present proximate to the device. If there is such a potential presence, the device remote can enter a full-powered detection mode to accurately determine the presence or absence of one or more humans, and take further actions.

Disclosed herein are system, method, and computer program product embodiments for the detection of human presence in front of a plurality of sensors such as those of speakers and a device with a processor, such as a television. Data gathered from the plurality of sensors may be analyzed by the processor to determine if one or more humans are present proximate to the device. Based on the determined presence or absence of one or more humans, further actions including, inter alia, customizing a home theatre experience for the one or more humans, making content recommendations, or activating parental controls can be taken by the device.

In one example, a sink device includes a display unit, a mirroring unit to mirror a first display screen of a first source device and a second display screen of a second source device at the display unit via a wireless network, a communication interface unit to receive a first input indicating a selection of the first display screen and interpret the first input as a control command to dynamically establish a peer-to-peer connection between the sink device and the first source device via a short-range wireless network, and a control unit to control media content associated with the first source device via the short-range wireless network based on a first human interface device (HID) command received at the sink device.
