Items of video content offered for viewing on a video-on-demand (VOD) platform of a digital TV service provider are each assigned a respective title and hierarchical address corresponding to hierarchically-arranged categories and subcategories within which the title for the video content is to be categorized. The title is listed in a location of an electronic program guide (EPG) using the same categories and subcategories as its hierarchical address. Any TV subscriber can access the EPG and navigate through its categories and subcategories to find a title for viewing on the TV. The EPG dynamically adjust its display listings of each level of categories, subcategories, and titles in order to minimize the number of remote control keypresses needed for a viewer to navigate to a title of interest. In one basic form, the EPG display is reordered by listing more frequently visited categories or subcategories first, and other less frequently visited categories or subcategories lower on the listing or out-of-sight on another page of the display.

The present application discloses techniques of implementing multi-screen display of interactive data. The techniques comprise receiving an interaction request from another computing device; establishing an interactive data connection channel with the other computing device according to the interaction request; receiving interactive data for the other computing device through the interactive data connection channel; determining a plurality of types of interactive data and corresponding interactive instructions included in the interactive data by analyzing field data in a data format of the interactive data based on a predetermined data format table; and performing display of the plurality of types of interactive data based on the corresponding interactive instructions.

Systems and methods for localizing portable devices are illustrated. One embodiment includes a method for locating a portable device in a network that includes several reference devices. The method measures characteristics of signals transmitted via signal paths between reference devices and a portable device, normalizes the measurements to estimate characteristics of the signal paths, and estimates the likelihood that the portable device is in a particular location. Systems and methods for training prediction models include a method that includes steps for receiving context data for a portable device in a system, wherein the context data includes localization data that describes a location of the portable device, identifying a predicted stationary device based on the context data using a prediction model, identifying a target stationary device from the several stationary devices, training the prediction model based on based on the predicted stationary device and the received input.

In accordance with increasing communication demand, means for efficiently providing mass downstream communication at a low cost are desired. Accordingly, a communication system providing supplemental downlink as well as multicast communication comprising a display control device for causing a display unit to display a video, and a communication terminal having an image capturing unit for directly capturing the video displayed by the display unit or capturing a video projected or reflected on a wall surface or the like is provided, wherein the display control device includes a video acquiring unit, a region identification unit, a video generating unit, and a display control unit, and the communication terminal includes a region identification unit, a decoding unit, and a mechanism for communicating a control signal for supplemental downlink by the above-described optical communication using means other than optical communication (means such as WiFi, mobile data communication or the like).

A display device connected to a signal source outputting a video signal using an encryption protocol and that transmits the encryption key to the signal source includes: a transmission unit that transmits an own encryption key uniquely set for the display device and an encryption key transmitted from another display device connected to the display device as a lower device to the signal source and another display device connected as an upper device; and a stop instruction unit that instructs another display device corresponding to a predetermined encryption key included in an encryption key group based on the order of the own encryption keys included in the encryption key group to stop transmitting the encryption key received when the own encryption key is included in the encryption key group including a plurality of encryption keys transmitted from another display device connected as the lower device.

An electronic apparatus is provided. The electronic apparatus includes a voice receiver, a communication interface, and a processor configured to, based on a user voice being obtained through the voice receiver, identify a mobile apparatus having a user account corresponding to the user voice from among at least one mobile apparatus communicably connected to the electronic apparatus through the communication interface, and transmit a control signal corresponding to the user voice to the identified mobile apparatus through the communication interface.

A method for controlling a display apparatus that displays an image based on an image signal supplied from an image supply apparatus that transitions to a first sleep mode in accordance with a situation in which a no-operation state lasts for a first period, the method including storing second information representing a second period, causing the display apparatus to transition to a second sleep mode in accordance with a situation in which the image signal is not supplied continuously for the second period, receiving first information representing the first period from the image supply apparatus, and setting the second information in such a way that the second period is shorter than a reference period in accordance with the first information.

A video playing method includes receiving first data sent by a first source device and second data sent by a second source device, where the first data comprises first display data and first audio data, and where the second data comprises second display data and second audio data; displaying the first display data in a first screen subarea of the destination device and the second display data in a second screen subarea of the destination device; and playing the first audio data by using a first speaker device and the second audio data by using a second speaker device, where the first speaker device is an external speaker wirelessly connected with the destination device, and where the second speaker device is a built-in audio module of the destination device.

The description relates to cooperatively controlling devices based upon their location and pose. One example can receive first sensor data associated with a first device and second sensor data associated with a second device. This example can analyze the first sensor data and the second sensor data to determine relative locations and poses of the first device relative to the second device and can supply the locations and poses to enable content to be collectively presented across the devices based upon the relative locations and poses.

An electronic device includes a communication device electronically communicating with a content presentation companion device operating as a primary display for the electronic device and at least one augmented reality companion device. One or more sensors detect multiple persons within an environment while the content presentation companion device operates as the primary display. One or more processors redirect an event notification intended for presentation on the primary display to the augmented reality companion device while both the content presentation companion device operates as the primary display for the electronic device and the multiple persons are within the environment of the electronic device. When communicating with two augmented reality companion devices, the one or more processors can direct subtitles associated with a content offering, sometimes in different languages, to at least a first augmented reality companion device and a second augmented reality companion device.
