An information processing apparatus includes a processor configured to acquire video data that enables playback of a video in which audio, an image, and a caption are chronologically synchronized, receive a section of a playback time of the video, the section being to be removed, and remove a partial caption that corresponds to the audio in the received section and that is at least a portion of the caption from the image in the received section.

A method for initiating synchronized playback within a user interface by requesting a plurality of media data and processing the plurality of data so that the plurality of data is compatible with the user interface. A portion of the data from the plurality of data are stored in an overflow buffer while a source buffer processes the plurality of data. The method may continue by generating a metadata object to facilitate sync playback on the user interface by determining what data is in the source buffer of the user interface that needs to be removed and searching for data using a first time format that is not natively supported by the user interface and converting the first time format into a second time format that is natively supported by the user interface. The method also includes synchronizing between videos using a sync playback controller from the generated metadata object, wherein each video is represented as a sequence in the source buffer of the user interface.

A first example playback device includes one or more processors and a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the first playback device to perform functions. The functions include generating a mixed audio signal comprising one or more components of a first audio stream and one or more components of a second audio stream; and playing the mixed audio signal, where the one or more components of the second audio stream of the mixed audio signal played by the first playback device are played in synchrony with a second playback device configured to play the second audio stream. An example non-transitory computer-readable medium and an example method, both related to the first example playback device, are also disclosed herein.

One embodiment of the present invention is a method for broadcasting information to one or more client devices from a broadcaster that is not a client device, which one or more client devices utilize presentation rates to present audio in broadcast information at various presentation rates using time-scale modification, and which method includes: (a) the broadcaster broadcasting non-time-scale modified information; and (b) the broadcaster broadcasting guidance information used to determine presentation rates for use by the one or more client devices in presentation of audio in the broadcast information using time-scale modification; wherein the guidance information is broadcast prior to or after a time of broadcast of the broadcast information.

An operating method of an electronic apparatus includes receiving a request to record first content; based on the first content being outputtable in multi-view, obtaining multi-view information for outputting the first content in multi-view; and storing the multi-view information together with the first content.

A method of reducing latency in a screen mirroring application, comprises receiving, by a receiver from a source device, an audio stream output by the source device; receiving, by the receiver from a processor, a video stream displayed on a first screen at the source device; receiving, by a receiver, audio and video time stamps; discarding, by a controller, the audio and video time stamps; outputting, by a decoder to a second display, the audio stream and video streams independent of timing indicated by the audio and video time stamps.

A method including: accessing a first configuration; accessing a primary video stream comprising a first set of video content, from a first online video platform; accessing a secondary video stream comprising a second set of video content; and at an initial time, combining the primary video stream and the secondary video stream according to the default viewing arrangement; at a first time, detecting the first trigger event in the primary video stream; in response to detecting the first trigger event, combining the primary video stream and the secondary video stream according to the first target viewing arrangement, and publishing the first composite video to a second video platform; and at a second time, detecting the second trigger event in the secondary video stream; in response to detecting the second trigger event, combining the primary video stream and the secondary video stream according to the second target viewing arrangement.

A video processing apparatus is provided, including an audio acquisition part; a video reception part; a video transmission time reception part receiving, from a video output device, a video transmission time, which is a time at which the video received by the video reception part is transmitted from the video output device; a video processing part; a video processing completion time acquisition part acquiring a video processing completion time, which is a time at which processing performed by the video processing part is completed; a delay time calculation part calculating a delay time, which is a time difference between the video processing completion time and the video transmission time; a delayed audio creation part creating delayed audio obtained by delaying the audio acquired by the audio acquisition part by the delay time; and an output part outputting the video processed by the video processing part and the delayed audio.

Technologies are generally described for a system to process a collection of video recordings of a scene to extract and localize audio sources for the audio data. According to some examples, video recordings captured by mobile devices from different perspectives may be uploaded to a central database. Video segments capturing an overlapping portion of the scene at an overlapping time may be identified, and a relative location of each of the video capturing devices may be determined. Audio data for the video segments may be indexed with a sub-frame time reference and relative locations as a function of overlapping time. Using the indices that include the sub-frame time references and relative locations, audio sources for the audio data may be extracted and localized. The extracted audio sources may be transcribed and indexed to enable searching, and may be added back to each video recording as a separate audio channel.

The present disclosure relates to a broadcast content production system, a broadcast content production method, and a program that are capable of avoiding occurrence of inconvenience in a broadcast content. The clock accuracy recognition unit recognizes accuracy of a clock of each of a plurality of video sources, and a time difference estimation and correction unit estimates a time difference of a stream from the video source with low accuracy of clock and corrects the time difference. Furthermore, a processing content control unit controls a processing content of production processing of the broadcast content in accordance with the accuracy of the clock of each of the video sources recognized by the clock accuracy recognition unit and with accuracy of time information, of each stream, having being corrected by the time difference estimation and correction unit. The present technology can be applied to, for example, a broadcast content production system using IP connection.
