Abstract: Some embodiments include an apparatus, method, and computer program product for high precision device synchronization of electronic devices in a shared medium. Some embodiments include a first electronic device that utilizes a combination of synchronization techniques to synchronize with a second electronic device. The first electronic device receives a first signal from the second electronic device that includes network-based synchronization data and marker data, and performs network-based synchronization with the second electronic device at a first synchronization accuracy. The first electronic device receives a second signal, and uses the marker data and phase lock synchronization to detect a frequency change of the second signal received, as well as to determine a corresponding time marker. The first electronic device updates a clock of the first electronic device based at least on the corresponding time marker, the network-based synchronization data, and the marker data.

Abstract: Disclosed herein are various embodiments for implementing audio enhancements based on video detection. An embodiment operates by receiving an audio clip corresponding to a video clip to be output simultaneously. A background of the video clip is detected. It is determined that the audio clip is to be output with one of wet sounds or dry sounds based on the detected background of the video clip. The audio clip is configured to enhance the determined one of wet sounds or dry sounds when the audio clip is output. The configured audio clip is provided to the audio output device to audibly output the configured audio clip with the enhanced wet sounds or dry sounds when the video clip is output.

Abstract: 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.

Abstract: 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.

Abstract: 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.
