A layered-keyframe-based, presentation recording service provides for presentation recording sessions, the recording of presentations, and the creation of presentation videos. A user records with the user's device the document pages and page annotations, as well audio and video streams, that are presented using the device during the course of a presentation recording session. The pages, annotations and video streams are efficiently and separately recorded as keyframes. These keyframes are used as document, annotation and video layers to create layered keyframes. A presentation video is created from the layered keyframes and the recorded audio stream. Users can then playback presentation videos at a time, place and manner that is available to, accessible by and/or convenient to them.

An electronic device is provided. The electronic device includes a first camera disposed on a first surface to obtain a first image, a second camera disposed on a second surface opposite to the first surface to obtain a second image, a communication module configured to establish communication with an external device, a plurality of microphones, and a processor electrically connected with the first camera, the second camera, the communication module, and the plurality of microphones. The processor is configured to identify an audio reception range for at least some of the plurality of microphones, while the first image and the second image are obtained, store a first audio signal collected through the plurality of microphones with the first image and the second image, when the audio reception range corresponds to a first range, and obtain and synthesize a second audio signal collected by the external device with the first audio signal, when the audio reception range corresponds to a second range narrower than the first range, and store the synthesized audio signal with the first image and the second image.

The present technique relates to an apparatus and a method for video-audio processing, and a program each of which enables a desired object sound to be more simply and accurately separated.

A video-audio processing apparatus includes a display control portion configured to cause a video object based on a video signal to be displayed; an object selecting portion configured to select the predetermined video object from the one video object or among a plurality of the video objects; and an extraction portion configured to extract an audio signal of the video object selected by the object selecting portion as an audio object signal. The present technique can be applied to a video-audio processing apparatus.

The present application discloses a method and device for processing multimedia information, an electronic equipment, and a computer-readable storage medium. The method for processing multimedia information includes: detecting whether multimedia configuration parameters have changed during a process of recording multimedia information; and recording the multimedia information based on the changed multimedia configuration parameters when detecting that the multimedia configuration parameters have changed. According to the embodiments of the present application, multimedia configuration parameters of the special effects such as stickers, make-up, filters, and mixing can be added during the recording of multimedia information, which improves the user experience.

A dashcam serving as an on-vehicle image capturing and recording apparatus includes: a cancellation processing unit configured to perform cancellation processing for reducing an electronic device sound on a sound acquired by a surrounding image/sound acquisition unit based on the characteristics of an electronic device sound acquired by an electronic device sound acquisition unit; and an abnormality detection unit configured to detect an abnormality of a vehicle, in which the acquired sound of the surroundings of the vehicle and a cancel sound are temporality recorded, a recording control unit is configured to discard the cancel sound and integrate only the sound of the surroundings of the vehicle with the image and record the integrated data when the abnormality detection unit does not detect an abnormality and otherwise records the cancel sounds and the sounds of the surroundings of the vehicle along with the image as overwriting prohibited data.

A method of processing a video includes capturing a first set of video data at a first definition, transmitting the first set of video data at a second definition lower than the first definition wirelessly to a user terminal, receiving a video edit request wirelessly from the user terminal, and finding video corresponding to edited video data described by the video edit request, thereby forming a second set of video data at a third definition. The video edit request is formed from editing the received first set of video data at the second definition at the user terminal.

A video generation device receives sound information from a distribution apparatus. The video generation device receives first timing information from the distribution apparatus. The video generation device causes a video-taking device to take a video. The video generation device reproduces one or more sounds indicated by the received sound information when the video being taken by the video-taking device. The video generation device identifies one or more timings of reproducing the one or more sounds indicated by the received sound information based on the received first timing information when the one or more sounds indicated by the received sound information being reproduced. The video generation device causes video information indicating the taken video and including second timing information indicating the one or more identified timings to be generated.

A control method of a camera device includes receiving audio data transmitted by an acoustic-electric device via Bluetooth communication and mixing the audio data with the video data to produce a video with audio. The audio data is recorded by the acoustic-electric device during a process of capturing video data by the camera device.

The present disclosure relates to an information processing apparatus, an information processing method and a program as well as a recording medium for enabling at least a bit rate of an image to be reproduced to be converted. A BD-J execution unit sets conversion equation information indicating a conversion equation for converting at least a bit rate of a graphics to be reproduced. A conversion unit converts at least the bit rate of the graphics to be reproduced by use of the conversion equation indicated by the conversion equation information set by the BD-J execution unit. The present disclosure can be applied to a reproducing apparatus and the like for reproducing an optical disc recording therein a stream file of AV stream of main video in a video format different in bit rate or color gamut, a BDJO file, a file of BD-J, and the like.

Provided are a video-recording method and apparatus, and an electronic device. The method comprises: during the process of playing target videos, obtaining a plurality of first pictures by intercepting, an editing process carried out by a user on an edit panel, and obtaining a plurality of second pictures by respectively carrying out picture conversion on the played target videos multiple times; then, obtaining a plurality of frame images by respectively superimposing the plurality of first pictures with the corresponding second pictures; and then generating recorded video segments according to a video stream obtained by synthesizing the plurality of frame images and an audio stream of target videos, thereby satisfying personalized requirements of users during a video-recording process.
