A method according to one aspect of the present disclosure includes the steps of: acquiring a play list including identification information indicating each of a plurality of elementary streams; selecting an elementary stream indicated by predetermined identification information from the acquired play list; acquiring a difference file including data that is not included in the selected elementary stream; and converting the selected elementary stream into an MP4 file format by combining data included in the difference file and data included in the selected elementary stream based on a manifest file corresponding to the selected elementary stream, the manifest file being necessary for the conversion of a file format based on a predetermined rule.

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.

A configuration is implemented that converts MMT format data to MPEG-2 TSV format data for recording onto medium, thereby permitting copy control in compliance with the initial copy control information. MMT format data with copy control information set therein is input and converted to MPEG-2 TS format data for re-cording onto information recording medium. The copy control information recorded in the service description table (MH-SDT) stipulated by the MMT format is acquired and, in accordance with predetermined conversion rules, used to generate the copy control information for recording to the program map table (PMT) stipulated by the MPEG-2 TS. For example, the EPN and CCI values to be recorded to the PMT are determined in accordance with the conversion rules.

The present invention provides a subtitle data editing method that simplifies the work of inputting subtitles to be displayed on contents such as moving images and facilitates quick and efficient editing work. By accepting a predetermined line feed operation twice consecutively in a state wherein a cursor is present in a subtitle input field in which the subtitle content is input, a subtitle input field is separated to be displayed on screen separations before and after the cursor. By accepting a predetermined line feed operation in a state where the cursor exists at the beginning of the second and subsequent lines, the line and the line directly above are separated and the subtitle input field is divided and displayed on screen, when the subtitle input field in which the subtitle content is input is a plurality of lines.

An automated solution to determine suitable time ranges or timestamps for captions is described. In one example, a content file includes subtitle data with captions for display over respective timeframes of video. Audio data is extracted from the video, and the audio data is compared against a sound threshold to identify auditory timeframes in which sound is above the threshold. The subtitle data is also parsed to identify subtitle-free timeframes in the video. A series of candidate time ranges is then identified based on overlapping ranges of the auditory timeframes and the subtitle-free timeframes. In some cases, one or more of the candidate time ranges can be merged together or omitted, and a final series of time ranges or timestamps for captions is obtained. The time ranges or timestamps can be used to add additional non-verbal and contextual captions and indicators, for example, or for other purposes.

A recording medium includes a video stream of a standard-luminance range and a video stream of high-luminance range, which are used selectively in accordance with a playback environment. The recording medium also includes a subtitle stream of the standard-luminance range and a subtitle stream of the high-luminance range, which are used selectively in accordance with the playback environment. A playlist file includes a management region where playback control information relating to a main stream is stored, and includes an extended region. The management region stores first playback control information specifying playing of the video stream of the high-luminance range and the subtitle stream of the high-luminance range in combination. The extended region stores second playback control information specifying playing of the video stream of the standard-luminance range and the subtitle stream of the standard-luminance range in combination.

An image capture apparatus displays a live view image that is based on an acquired image, stores image data that is based on the acquired image, and acquires additional information associated with a predetermined subject included in the live view image. The image capture apparatus superimposes the additional information on the live view image and displays the resulting image before the image data is stored, and stores the image data and the acquired additional information in association with each other.

In some implementations, a user device can be configured to create media messages with automatic titling. For example, a user can create a media messaging project that includes multiple video clips. The video clips can be generated based on video data and/or audio data captured by the user device and/or based on pre-recorded video data and/or audio data obtained from various storage locations. When the user device captures the audio data for a clip, the user device can obtain a speech-to-text transcription of the audio data in near real time and present the transcription data (e.g., text) overlaid on the video data while the video data is being captured or presented by the user device.

An image capture apparatus displays a live view image that is based on an acquired image, stores image data that is based on the acquired image, and acquires additional information associated with a predetermined subject included in the live view image. The image capture apparatus superimposes the additional information on the live view image and displays the resulting image before the image data is stored, and stores the image data and the acquired additional information in association with each other.

Real-time metadata tracks recorded to media streams allow search and analysis operations in a variety of contexts. Search queries can be performed using information in real-time metadata tracks such as closed captioning, sub-title, statistical tracks, miscellaneous data tracks. Media streams can also be augmented with additional tracks. The metadata tracks not only allow efficient searching and indexing, but also allow insertion of content specific advertising during appropriate portions of a media stream based on the content of the metadata tracks.
