There is provided a data creation method for efficiently performing volume adjustment of a sound of each subject according to a state of each of a plurality of subjects. A data creation method includes: an association step (step S10 and step S11) of associating the microphone with each subject possessing each of the microphones; a recording step (step S12, step S20, and step S21) of recording moving image data using the imaging apparatus; a sound recording step (step S13) of recording sound data of each subject using each of the microphones in synchronization with a start of the recording step; a detection step (step S14 and step S15) of automatically detecting a state of the subject during the recording step; and an addition step (step S16 to step S19) of adding, to the moving image data, an identification code for volume adjustment of the sound data of each subject based on a result of the detection step.

One particular implementation of the present invention may take the form of a method and system for encoding decoding 3-D multimedia content. In one example, visual content having a plurality of source frames may be processed to create a plurality of first and second type frames from each of the plurality of source frames. The plurality of first and second type frames may be arranged to create modified content, and generating a distinguishing signal for the visual content, which may distinguish the first type frame from the second type frame. In another examples, the present invention may take the form of a method decoding 3-D multimedia content encoded with at least content frames and null frames. The method may operate to receive the 3-D multimedia content, extract at least one content frame, at least one null frame, and display information. The method may further operate to reconstruct the content and null frames in a display-sequential manner using the display information to indicate the display order of the at least one content frame. In some examples, the method and system for encoding and decoding multimedia content may encode the multimedia content such that the at least one null frame may not be displayed by a display device.

A recording apparatus with a battery attachable to and detachable from, includes a positioning unit configured to determine position information based on signals received from satellites, a retaining unit configured to retain the position information determined by the positioning unit, and a control unit, wherein the control unit determines whether latest position information is valid based on an acquisition time of the latest position information from among pieces of the position information retained by the retaining unit and a current time, and uses position information determined as valid as current position information, and wherein the control unit determines whether the latest position information is valid in response to the battery being attached.

The present technology relates to a reproduction device, a reproduction method, and a recording medium that enable content having a wide dynamic range of brightness to be displayed with an appropriate brightness. A recording medium, on which the reproduction device of one aspect of the present technology performs reproduction, records coded data of an extended video that is a video having a second brightness range that is wider than a first brightness range, brightness characteristic information that represents a brightness characteristic of the extended video, and brightness conversion definition information used when performing a brightness conversion of the extended video to a standard video that is a video having the first brightness range. The reproduction device decodes the coded data and converts the extended video obtained by decoding the coded data to the standard video on the basis of the brightness conversion definition information.

The various embodiments described herein include methods, devices, and systems for categorizing motion events. In one aspect, a method is performed at a camera device. The method includes: (1) capturing a plurality of video frames via the image sensor, the plurality of video frames corresponding to a scene in a field of view of the camera; (2) sending the video frames to the remote server system in real-time; (3) while sending the video frames to the remote server system in real-time: (a) determining that motion has occurred within the scene; (b) in response to determining that motion has occurred within the scene, characterizing the motion as a motion event; and (c) generating motion event metadata for the motion event; and (4) sending the generated motion event metadata to the remote server system concurrently with the video frames.

Systems and methods for linking time-based media and temporal metadata provide single command control during editing of media having associated temporal metadata. A single control enables an editor to switch between monitoring both source media and its corresponding temporal metadata and monitoring both a pre-recorded version of the media and its corresponding temporal metadata. Another single control enables an editor to start and stop the recording of a source media track and its corresponding source temporal metadata. In one application, the editing is performed for media tracks having time-based spatial metadata for playback in immersive environments with the spatial metadata defining an apparent location of sound objects within the immersive environment.

Provided is an information processing device according to the present disclosure including a photographing information acquisition unit configured to acquire photographing information, which indicates photographing being performed in another device, from the other device, and a function activation unit configured to activate a function related to a photographed image depending on the acquisition of the photographing information. In particular, the function is a function of recording a voice uttered by a user with respect to photographing corresponding to the photographing information. This configuration makes it possible for a separate device to give a comment by voice to a picture photographed by the other device.

The present invention relates to an audio content restitution method in a receiver of audio and/or audiovisual content, the receiver being adapted to the restitution of the audio content, the audio content being received encoded and containing a succession of frames of audio samples and pointer type information on at least one portion of the audio samples of the frames. According to a particular embodiment, the audio content restitution method comprises: a selection of audio samples from the frames, the selected audio samples being identified from the pointer type information; a restitution of the only samples selected.

A method for processing video data is performed by a data processing unit (DPU). The method includes identifying, by the DPU of an edge device, a contextual stitching trigger event; in response to identifying the contextual stitching trigger event: identifying video data chunks, contextual metadata, indexing metadata, and authentication and authorization (AA) metadata associated with the contextual stitching trigger event; generating a virtual blob based on the video data chunks, contextual metadata, indexing metadata, and authentication and authorization AA metadata; making a first determination that a playback request is obtained from a user, wherein the playback request comprises user authentication information; and in response to the first determination: making a second determination that the user authentication information matches the AA metadata; and in response to the second determination; encoding the video data chunks into a single stream and initiating playback for the user.

A multimedia file and methods of generating, distributing and using the multimedia file are described. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, data that can be used to generate a menu interface to access the contents of the file and ‘meta data’ concerning the contents of the file. Multimedia files in accordance with several embodiments of the present invention also include references to video tracks, audio tracks, subtitle tracks and ‘meta data’ external to the file. One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames and encoded menu information.
