Abstract: Apparatus, systems, and methods are disclosed for cancellation and content recognition of audio received over a High-Definition Multimedia Interface (HDMI)/Audio Return Channel (ARC) port of a display device. The media device receives audio over the HDMI/ARC port from the display device, processes the audio by identifying, decoding, re-encoding, and fingerprinting the audio with identification information, and subsequently streams the audio within the media streaming environment, including to external speakers, such as voice-enabled speakers. Based on the identification information and recognized content of the processed audio, the media device offers additional content for streaming to a user. The media device continuously monitors for spoken voice received over a voice-enabled speaker while the media device simultaneously receives, processes, and streams audio from the display device. By cancelling the part of the streaming audio received simultaneously with the spoken voice received, the media device enables the voice-enabled speaker to distinguish a voice command.

Abstract: A method for dynamically controlling enhancement of an audio stream is provided, where the audio stream defines a sequence of audio segments over time. Each audio segment defines a waveform having a plurality of waveform attributes. For each audio segment of the sequence of audio segments, the method includes: (i) determining a set of waveform-attribute values of the audio segment's waveform attributes, (ii) computing a first distance between the determined set of waveform-attribute values and a first predefined set of waveform-attribute values representative of speech, and computing a second distance between the determined set of waveform-attribute values and a second predefined set of waveform-attribute values representative of music, (iii) using the computed first and second distances as a basis to classify the audio segment as primarily speech or rather primarily music, and (iv) controlling, based on the classifying, whether or not to enhance the audio segment for output.

Abstract: A method includes receiving, by a first device that is included in a first network and a second network, a request from a second device to join the first network. The method also includes making, by the first device, determinations of whether to transmit the second device a first credential corresponding to the first network and whether to transmit the second device a second credential corresponding to the second network. The method also includes using the determinations as a basis to select, as content for a message, the first credential, the second credential, or an indication that the second device is not allowed on the first network and not allowed on the second network. The method also includes transmitting the message that includes the content to the second device.

Abstract: 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.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for identifying audio characteristics of 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 an airtime delay based on the time of receipt and a time of transmission of the spread spectrum signal. The first electronic device determines a direction of the second electronic device based on the spread spectrum signal and beam forming techniques. The first electronic device adjusts playback of audiovisual content at the second electronic device and a third electronic device for a location based on the airtime delay and the direction.

Abstract: 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 among multiple speakers. In some embodiments, a first smart speaker receives a spread spectrum signal from a second smart speaker over an audio data channel. The first smart speaker despreads the spread spectrum signal based on a spreading code. The first smart speaker determines a time of receipt of the spread spectrum signal based on the despreading. The first smart speaker receives a time of transmission of the spread spectrum signal. The first smart speaker then calculates a playback delay based on the time of receipt and the time of transmission. Then the first smart speaker controls the playback of the audiovisual content based on the playback delay.

Abstract: Disclosed herein are system, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for reducing and/or eliminating false positive alarm triggers. Detector devices positioned throughout an environment scan for known events that are likely indicative of an alarm condition. A source device that may generate such a sound or image may imprint a fingerprint on to the event that can be detectable by the detector devices but is imperceptible to humans. Additionally, the detector devices may use directionality and known locations of source devices to determine if a triggering event occurred at a known location of a source device. An alarm suppression decision may occur at the detector device and/or relevant information may be sent from the various detectors to a central console for a final alarm decision.

Abstract: In one aspect, an example method includes drawing a current through a doorbell circuit. While drawing the current through the doorbell circuit, the example method includes determining, by the doorbell device, a maximum doorbell circuit current that will not activate a doorbell chime. Based on determining the maximum doorbell circuit, the example method includes configuring a doorbell device to draw the determined maximum doorbell circuit current through the doorbell circuit. Determining the maximum doorbell circuit current that will not activate the doorbell chime further includes: (i) determining whether the current being drawn through the doorbell circuit has activated the doorbell chime, (ii) if the current being drawn through the doorbell circuit has activated the doorbell chime, decrementing the current drawn through the doorbell circuit, and (iii) if the current being drawn through the doorbell circuit has not activated the doorbell chime, incrementing the current drawn through the doorbell circuit.

Abstract: Described herein are various embodiments for network-based audio playback. An embodiment operates by determining that a media device is configured to stream audio content to one or more wireless speakers over a first wireless network. A second wireless network over which the media device is configured to stream the audio content to the one or more wireless speakers is established by the media device. A signal to the one or more wireless speakers to switch from the first wireless network to the second wireless network is provided by the media device. The audio is provided to the wireless speakers for playback over the second wireless network.
