A display device including a display; a speaker, and a controller configured to receive a first keycode from a first external speaker, receive a signal including an identification of the first external speaker, and connect the display device and the first external speaker to output sound in a surround sound mode or a simultaneous sound mode in response to the received first keycode corresponding to the identification of the first external speaker.

A method is disclosed. The method includes monitoring, by a monitoring module of a first application, multimedia information provided by at least one second application of multiple different types, wherein the multimedia information includes at least one of the multimedia information captured by a device, the multimedia information received by the device, and the multimedia information displayed on the device. The at least one second application is configured to provide different types of sexual entertainment-related content. The method also includes identifying, by an identification module, the sexual entertainment-related content in the multimedia information, generating, by a generation module, a control signal according to the sexual entertainment-related content, and transmitting, by a transmission module of the first application, the control signal to a sexual stimulation device.

The present disclosure provides a display device comprising: a display unit for displaying a content; and a processor, wherein the processor is configured to: broadcast first channel information providing the content to at least one other display device if a mirroring operation of displaying the content on an external device is being performed; obtain hash data and a content ID associated with the content from the at least one other device; transmit the content ID and the hash data to a scene recognition information server; and obtain scene recognition information corresponding to the content via the scene recognition information server.

The present invention relates to a portable TV comprising: a display module for outputting content; a housing for accommodating the display module; four legs detachable from a lower case of the housing; and a control unit. The control unit detects when an upper case of the housing is opened, determines the current location of the TV, determines whether the current location is the same as the location immediately before a shutdown, and if the current location is the same as the location immediately before the shutdown, operates in the mode immediately before the shutdown. The mode includes a first mode and a second mode, wherein the first mode is a mode in which the display module maintains a state of being coupled to the housing, and the second mode is a state in which the display module stands in the housing.

A method includes for a plurality of devices, each of the plurality of devices having access to a first video stream from at least one of a plurality of streamers of the first video stream, confirming authorization to access the first video stream from one of the plurality of streamers of the first video stream, selecting a first streamer from the plurality of the streamers, receiving the first video stream from the first streamer, transmitting the first video stream to the plurality of devices having confirmed authorization.

Provided are a display apparatus and a person recognition and presentation method. The display apparatus includes a display and a controller that is in communication with the display. The controller is configured to: associated information of a display interface of the display and generate a scenario image for recognition in response to a user command; obtain facial feature information for recognition in the scenario image; obtain similar facial feature information when a matching confidence level of pre-stored facial feature information in a database with the facial feature information for recognition does not exceed a preset confidence level; obtain average-person recognition data; generate a sharing control uniquely matching with the facial feature information for recognition; and control the display to present the average-person recognition data and the sharing control on a current display interface.

One embodiment of the present invention provides a method for controlling a TV, the method being characterized by comprising the steps of: receiving information about a remote control device and information about an external device from the remote control device through UWB communication; calculating the relative distance and angle of the external device on the basis of the information about the remote control device and the information about the external device; performing Bluetooth pairing with the external device on the basis of the relative distance and angle of the external device; executing a surround sound mode providing surround sound; and automatically setting the volume of the external device on the basis of the relative distance and angle of the external device.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol. In an ATSC 3.0 environment, receivers (including consumer and professional receivers) have signal reception parameters and antenna factors available to them. These reception parameters, together with time and location data are transmitted to one or more servers that maintain databases of reception characteristics. This data is analyzed such that a set of likely receivable signals (based on reception parameters, date/time, location, geographical features, transmitter information, etc.) is identified. Receivers query the servers to receive information indicating the set of likely receivable signals to reduce channel scan time by scanning only or first for more-receivable channels. Also, difficult reception locations identified in the data collected by the servers are used in aggregate to guide RF improvements (e.g., adding SFN transmitters). Further, the data collected by the servers may provide data to be used to feed MFN data.

A display device including at least one speaker; a moveable display configured to be moved from a first position to a second position, wherein the display has a first spatial physical relationship with the at least one speaker at the first position and has a second spatial physical relationship with the at least one speaker at the second position; and a processor configured to control the at least one speaker and the display. In addition, the processor is configured to output audio from the at least one speaker, when the display is in the first position, and when receiving an information signal indicating the display has been moved to the second position from the first position, change the output of the audio from the at least one speaker based on the second spatial physical relationship.
