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.

An imaging device in which an imaging sensor that captures an image and a display unit that displays the image are provided includes: an image processing unit configured to perform roll correction on the image; a control unit configured to control an output of the image; and a display control unit configured to display the output image on the display unit. The image processing unit performs the roll correction such that a degree of correction of the roll correction when the image is to be output to only the display unit is less than a degree of correction of the roll correction when the image is to be output to the display unit and an output destination other than the display unit.

A system and method of transmitting respective audio streams to a plurality of end points, such as headphones, earphones, headsets, speakers, etc. is disclosed. Different audio streams are transmitted to each of the plurality of end points. The end points may be arranged to audibly output received audio streams, and so each end point may audibly output a respective different audio stream, i.e. the respective audio streams may be mutually different from each other.

Disclosed techniques include audio and visual stream rendering modification based on device rotation metric. One or more media streams are received from a server. The one or more media streams are targeted for display on a handheld media stream playback device. An orientation of the handheld device is determined during playback of at least one of the one or more media streams on the handheld device. A change in orientation of the handheld device is detected. The change occurs during playback of the at least one of the one or more media streams. Based on detecting the change in orientation, a rotation angle of the handheld device is calculated. Based on the rotation angle, the playback of at least one of the one or more media streams is changed on the handheld device.

An image capturing apparatus includes a first sound input unit, a second sound input unit different from the first sound input unit, an image capturing unit, and a control unit, wherein the control unit generates moving image data with sounds from moving image data generated by the image capturing unit and sound data generated by the first sound input unit, wherein, in a case where a sound corresponding to a voice instruction to control the image capturing apparatus is detected from sound data input to the second sound input unit, the control unit controls the image capturing apparatus based on the voice instruction, and wherein the second sound input unit includes a wireless communication unit configured to receive sound data from an external apparatus.

An apparatus, method and computer program product for: receiving image information comprising a visual representation of a scene and audio information comprising at least one sound source, determining an axis of interest within the visual representation of the scene, the axis of interest being associated with the at least one sound source, determining, with respect to the axis of interest, an audio rendering axis associated with a first audio channel and a second audio channel, the first audio channel and the second audio channel comprising respective audio signals relating to the at least one sound source, determining a default rendering axis for the image information and the audio signals, and determining alignment control information for aligning the default rendering axis and the audio rendering axis.

The disclosure relates to an electronic apparatus, a control method thereof, and a recording medium. The electronic apparatus includes: a signal processor configured to process a sound signal; and a processor configured to acquire positional information of a speaker that outputs sound, based on the processed sound signal, and perform a first correction so that a sound image of the sound signal has a predetermined reference spatial acoustic characteristic based on the acquired positional information of the speaker, and perform a second correction so that the sound image of the sound signal on which the first correction is performed has a target spatial acoustic characteristic.

Embodiments of the present application disclose a method for audio and video processing and an electronic device. A first decoding result corresponding to main channel audio and a second decoding result corresponding to audio description are acquired according to audio data in an audio and video file; and the first decoding result as well as an audio mixed result of the first decoding result and the second decoding result are output respectively through different audio output devices, so that in a scenario where a normal user and a visually impaired user watch audio and video at the same time, the normal user and the visually impaired user can select different audio output devices for audio listening to ensure that the two do not affect each other, which satisfies the needs of the normal user and the visually impaired user to watch at the same time.

A system and method of transmitting respective audio streams to a plurality of end points, such as headphones, earphones, headsets, speakers, etc. is disclosed. Different audio streams are transmitted to each of the plurality of end points. The end points may be arranged to audibly output received audio streams, and so each end point may audibly output a respective different audio stream, i.e. the respective audio streams may be mutually different from each other.

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, an electronic device transmits a spread spectrum signal to a dumb speaker over a data channel using a spread spectrum code. The electronic device then receives the spread spectrum signal played back auditorily by the dumb speaker. The electronic device despreads the spread spectrum signal based on the spreading code. The electronic device determines a time of receipt of the spread spectrum signal. The electronic device calculates an audiovisual output path delay for the dumb speaker based on the time of receipt and a time of transmission. The electronic device then synchronizes the playback of the audiovisual content at the dumb speaker and another electronic device based on the audiovisual output path delay.
