A display device according to an embodiment of the present invention may comprise: a display unit for displaying a content image; a microphone for receiving voice commands from a user; a network interface unit for communicating with a natural language processing server and a search server; and a control unit for transmitting the received voice commands to the natural language processing server, receiving intention analysis result information indicating the user's intention corresponding to the voice commands from the natural language processing server, and performing a function of the display device according to the received intention analysis result information.

An example display device may include a voice signal receiver, a display, at least one memory storing an application supporting a contents providing service and storing instructions, a communication circuit communicating with at least one external server supporting the contents providing service, and at least one processor. The contents providing service may provide contents files of a first type and contents files of a second type.

Provided is a display device including a display unit, a storage unit configured to store information on a web page, a microphone configured to receive a user's voice command, a network interface unit configured to perform communication with a natural language processing (NLP) server, and a controller configured to transmit text data of the voice command to the NLP server, to receive intention analysis result information corresponding to the voice command from the NLP server, to select, as a final candidate address, one of a plurality of candidate addresses related to a search word included in the received intention analysis result information if the search word is not stored in the storage unit, and to access a website corresponding to the selected final candidate address.

A mobile device responds in real time to media content presented on a media device, such as a television. The mobile device captures temporal fragments of audio-video content on its microphone, camera, or both and generates corresponding audio-video query fingerprints. The query fingerprints are transmitted to a search server located remotely or used with a search function on the mobile device for content search and identification. Audio features are extracted and audio signal global onset detection is used for input audio frame alignment. Additional audio feature signatures are generated from local audio frame onsets, audio frame frequency domain entropy, and maximum change in the spectral coefficients. Video frames are analyzed to find a television screen in the frames, and a detected active television quadrilateral is used to generate video fingerprints to be combined with audio fingerprints for more reliable content identification.

A guide voice output control system includes a voice output control unit having a function of outputting a guide voice in response to a trigger and a function of executing interaction related processing having a reception stage for receiving voice, a recognition stage for recognizing voice, and an output stage for outputting voice based on a recognition result, in which the voice output control unit controls the output of the guide voice according to the processing stage of the interaction related processing when the trigger is generated during the execution of the processing, and dynamically controls the output of the guide voice according to whether or not the processing stage is a stage that does not affect the accuracy of voice recognition or listening difficulty of a user even if the guide voice is output.

A display device according to an embodiment of the present disclosure comprises: a display unit; a user input interface unit which receives a signal from a remote control device; and a control unit which receives a voice signal, and on the basis of data extracted from the voice signal, sets an external device connected to the display device as an object to be controlled by the remote control device.

Systems and methods are described for power control in a media receiver device having a plurality of electronic components, using a trained model. Input signals are received from at least one electronic component. An alertness state of the device is determined using a machine learning based determiner trained to process the received input signals and predict a subsequent alertness state identifying at least one additional component or device. Power consumption by the identified components and devices is controlled based on the predicted alertness state.

Methods, apparatus, systems and articles of manufacture are disclosed to identify user presence to a meter. An example apparatus includes memory, instructions, and at least one hardware processor to execute the instructions to at least: obtain presence information from a configuration device, the configuration device separate from the apparatus, the presence information indicating that user is present at the apparatus; verify the presence information matches user information, the user information stored in a memory of the apparatus; cause a confirmation prompt to be displayed on the configuration device, the confirmation prompt to indicate the presence information was obtained by the apparatus; and store the presence information in memory.

An audience measurement computing system for monitoring a media presentation device in a monitored environment is described and includes a network interface, at least one processor, and a non-transitory computer-readable medium comprising instructions executable by the processor(s). The computing system is configured to obtain, via a cable connected to an input port of the media presentation device, a voltage signal generated by the media presentation device based on an operational state of the media presentation device; compare voltage indicated by the voltage signal to a threshold; based on the comparing, generate timestamped operational state data comprising a record indicative of when the media presentation device is in an on-state; obtain audience measurement data representing one or more media signals communicated to the media presentation device; and transmit, via the network interface over a network and to a central facility, the timestamped operational state data and the audience measurement data.

The present disclosure provides a live video broadcast method performed by a terminal device. The method includes: receiving a live broadcast command to live broadcast a video game in real time, and creating a video buffer for the video game based on the live broadcast command; while playing the video game in real time, extracting video picture frames from the video game and storing them in the video buffer; collecting voice data by using a microphone of the terminal device, and synchronously synthesize the voice data and the video picture frames stored in the video buffer into a video streaming media file; and uploading the video streaming media file to a live broadcast server for live broadcasting the video streaming media file on other mobile devices.
