摘要： Disclosed herein are system, method, and computer program product embodiments for detecting human presence in front of a plurality of sensors, such as speaker sensors, and a device with a processor, such as a television. An example method includes varying, during a collection routine, a respective signal strength of one or more of a plurality of transmitters. The example method further includes receiving results of the collection routine in a form of raw data from a plurality of sensors. The example method further includes determining, by at least one processor, a respective geographical position of one or more humans present within a predetermined geographical range of the at least one processor based on the raw data from the plurality of sensors. Subsequently, the example method includes executing an action based on the respective geographical position of the one or more humans.

摘要： 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.

摘要： 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.

摘要： Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for identifying electronic devices in a room using a spread code. In some embodiments, a first electronic device receives a spread spectrum signal from a second electronic device over an audio data channel. The first electronic device determines a time of receipt of the spread spectrum signal based on despreading. The first electronic device calculates a distance between the first electronic device and the second electronic device based on the time of receipt and a time of transmission. The first electronic device determines the second electronic device is not in the room with the first electronic device based on the calculated distance.

摘要： Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for synchronizing playback of audiovisual content with a dumb speaker. In some embodiments, a display device transmits a spread spectrum signal to a dumb speaker over a data channel using a spread spectrum code. The display device then receives the spread spectrum signal from the dumb speaker over an audio data channel. The display device despreads the spread spectrum signal based on the spreading code. The display device determines a time of receipt of the spread spectrum signal. The display device calculates an audiovisual output path delay for the dumb speaker based on the time of receipt and a time of transmission. The display device then synchronizes the playback of the audiovisual content at the dumb speaker and a smart speaker based on the audiovisual output path delay.

摘要： Disclosed herein are computer-implemented method, system, and computer-readable storage-medium embodiments for implementing sound generation with adaptive directivity. An embodiment includes at least one computer processor that may retrieve and process an audio sample of a content instance, via an algorithm configured to generate a classification of the audio sample. Directivity may be determined, corresponding to a first audio signal to be output via an audio output device. The first audio signal may correspond to the audio sample of the content instance, and the audio output device may include at least one loudspeaker, for example. A second audio signal may be generated from the classification and the directivity. In some embodiments, another classification of the audio sample may be generated based at least in part on a second algorithm that may process information including a video image corresponding to the audio sample and/or additional audio characteristic(s) detected in the audio sample.
