Abstract: ATSC 3.0 IP-based data is broadcast in signed and encrypted messages to one or more ATSC 3.0 receivers that control a barrier such as a gate, usually closed to traffic, in the event of an emergency, such as a fire, to open the barrier to allow additional escape routes or to provide access for emergency vehicles. The ATSC 3.0 system supports a wake-up mechanism which allows a receiver to go to a power saving mode. Periodically the receiver wakes up to check for the wake-up bit. Receipt of an “open” message actuates a battery powered or solar assisted system to open the gate while saving on power consumption. Present techniques can also be used to send messages such as Amber alerts to roads, freeways, and other public signage and to control remote water pumping and sewer pumping stations which currently depend on point-to-point UHF radio links.

Abstract: Placement of Closed Captioning (CC) in content by a content provider is overridden by means of a user interface (UI) that allows the user to place CC on screen on top of the video. The CC may be derived directly from the audio and synchronized with play of the audio and video.

Abstract: Implementations generally relate to acoustic calibration of an audio system. In some implementations, a method includes generating one or more signals that include sound sequences. The method further includes emitting the one or more signals from one or more speakers in an audio environment. The method further includes receiving the one or more signals at one or more microphones in the audio environment. The method further includes measuring one or more acoustic attributes of the one or more signals that are received at the one or more microphones. The method further includes comparing current values of the one or more acoustic attributes that are measured to stored values of the one or more acoustic attributes. The method further includes determining if recalibration is needed based on the comparing of the current values to the stored values.

Abstract: Faster channel change time in ATSC such as ATSC 3.0 is effected by using the native tuner of a display device to present a currently demanded channel and a second tuner, which can be dongle-based, to tune/scan preemptively in the background based upon heuristics such as usage pattern of the user. If the user is pressing channel-up key using a remote control, the second tuner can be scanning and tuning the next channel in the channel map to preemptively tune to a second channel likely to be desired by the user for immediate presentation of that channel through the second tuner.

Abstract: A first electronic device and a method for controlling functional parameters and rendering operational preview of a second electronic device are provided. The first electronic device receives a user input indicative of control commands to operate the second electronic device associated with first electronic device. The first electronic device determines a requested set of changes in the value of a functional parameter, based on the received user input. The first electronic device controls the second electronic device to operate based on the determined requested set of changes. The first electronic device or the second electronic device is controlled to render a first operational preview associated with the determined requested set of changes, based on the control of the second electronic device.

Abstract: An electronic device and a method for virtual audio jack for audio playback on external device is disclosed. A first electronic device receives media content including audio content and video content. The first electronic device receives a user input indicative of a request to render the audio content on a second electronic device (for example, an external device) associated with the first electronic device. The first electronic device transmits a content request to a media server including the audio content, based on the received user input. The first electronic device renders the received media content on the first electronic device. The first electronic device controls the second electronic device to render the audio content, based on the transmitted content request. The rendering of the audio content on the second electronic device is based on a synchronization of the rendering of the media content on the first electronic device.

Abstract: An acoustic-based Direction of Arrival (DoA) system uses acoustic information to determine the direction of incoming sound, such as a person talking. The direction of the sound is then used to focus a laser-based time of flight (ToF) system to narrow the area of laser illumination, improving the signal to noise ratio because laser illumination is focused on the direction of the sound. The DoA system also provides elevation information pertaining to the source of the sound, to further narrow the required field of view of the laser ToF system.

Abstract: To reduce energy consumption in a low power mode, a display device such as a TV deenergizes its display and components in its network stack while leaving its infrared (IR) receiver on. A home network device that is not a conventional TV remote control (RC), for instance, a smart speaker, can receive a voice command to energize the TV, and instead of sending a wake up command to the TV through the home network, transmits an IR wake up command or sonic wake up command or non-IP RF command to the TV, which energizes its network stack and display in response.

Abstract: A system and method for signaling changes in aspect ratio of media content is provided. The system acquires a video stream to be transmitted to an electronic device and determines aspect ratio information associated with content included in the video stream. The system further determines a change in an aspect ratio of the content based on the aspect ratio information. The change in the aspect ratio may be from a first value at a first timestamp to a second value at a second timestamp for a duration of the content. The system signals information indicative of the determined change to the electronic device.

Abstract: An electronic device and method for emergency alert message detection based on audio-video information is disclosed. The electronic device receives first media content received over a first broadcast channel. The electronic device renders second media content, which is different from the first media content. The electronic device further detects, from the received first media content, a set of objects associated with a geo-location corresponding to the electronic device. The set of objects corresponds to an emergency at the geo-location. The electronic device further detects an emergency alert audio in the received first media content. The electronic device further extracts an emergency alert message received over a second broadcast channel associated with the geo-location based on the detected set of objects and the emergency alert audio in the received first media content. The electronic device further renders an emergency alert signal associated with the emergency alert message.

Abstract: A system to process antenna-captured OTA-transmitted RF signals for delivery to a receiver within a building includes a pre-amplifier connected to a single antenna, mounted on a mast positioned outside the building, the receiver, and a solar power unit. The solar power unit delivers power to operate the pre-amplifier. The pre-amplifier amplifies the antenna-captured signals before delivering them to the receiver at a carrier to noise ratio above an acceptable threshold, independent of where the receiver is located within the building.

Abstract: Provided is an electronic device that captures a first image of a user. The electronic device determines a position of eye gaze of the user on a first UI element of a plurality of UI elements displayed on a first display screen of the electronic device, based on the first image. The electronic device selects the first UI element based on a determination of the position of the eye gaze on the first UI element for a time interval. The electronic device transmits a first control signal to a media display device, based on the selection of the first UI element. The electronic device receives a feedback image from the media display device. The feedback image indicates control of the media display device based on the first control signal. The electronic device controls the first display screen to display the feedback image with the plurality of UI elements.
