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.

A playback device acquires first management information that stores first playback control information and second management information that stores second playback control information. The first playback control information specifies that a video stream of a high-luminance range is to be played, and the second playback control information specifies that a video stream of a standard-luminance range is to be played. A video player acquires and plays the video stream of the high-luminance range based on the first playback control information in a case of playing the content as the high-luminance range. The video player acquires and plays the video stream of the standard-luminance range based on the second playback control information in a case of playing the content as the standard-luminance range.

An information processing apparatus is to include: a text acquisition unit configured to acquire text data obtained by converting audio data into text; and a data management unit configured to perform a process of receiving image data and audio data related to the image data that are transmitted from an imaging apparatus, and then setting text data acquired for the audio data by the text acquisition unit as metadata corresponding to the image data.

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.

To enable MMT format data to be recorded as BDAV format data in a medium, and a list of video-recorded contents to be displayed and reproduced by an application for BDAV. Data to be recorded in a playlist or clip information file defined in a BDAV format is extracted from MMT format data input on a broadcast wave or the like thereby to generate a data file thereof. For example, data applied to display a list of video-recorded contents is extracted from MMT-SI or TLV-SI in the MMT format data and recorded in the playlist or clip information file.

A video recording system is disclosed and claimed. In particular, the disclosed video recording system maintains a master stream of video and audio when recording is initiated, but also allows the user to create additional label streams by activating an input control. The label stream can be terminated by activating the input control a second time. The label stream comprises only the portion of the video and audio between the activations of the input control, while the master stream will contain all audio and video that is recorded on the device.

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.

A decoding system decodes a video stream, which is encoded video information. The decoding system includes an attribute information acquirer that acquires first attribute information, indicating whether a dynamic range of luminance of the video stream is a first dynamic range or a second dynamic range that is wider than the first dynamic range, and a decoder that acquires the video steam and generates decoded video information. The decoding system also includes an outputter that, in a case where the first attribute information indicates the second dynamic range, outputs the decoded video information and maximum luminance information indicating a maximum luminance of the video stream in accordance with the second dynamic range. Further, in other cases, the outputter outputs the decoded video information and maximum luminance information indicating the maximum luminance of all pictures in the video stream.

A decoding system decodes a video stream, which is encoded video information. The decoding system includes a decoder that acquires the video steam and generates decoded video information, a maximum luminance information acquirer that acquires maximum luminance information indicating the maximum luminance of the video stream from the video stream, and an outputter that outputs the decoded video information along with the maximum luminance information. In in a case where the video stream includes a base video stream and an enhanced video stream, the decoder generates base video information by decoding the base video stream, an enhanced video information by decoding the enhanced video stream, and generates the decoded video information based on the base video information and the enhanced video information, and the outputter outputs the decoded video information, along with the maximum luminance information.

A decoding method of a video stream, which is encoded video information. The video stream includes a base video stream, and an enhanced video stream, which is a video stream to enhance luminance of the base video stream, and a describer that contains the combination information of the base video stream and the enhanced video stream. The decoding method includes acquiring the describer, and identifying the combination of the base video steam and the enhanced video stream. The decoding method also includes generating base video information by decoding the base video stream, generating enhanced video information by decoding the enhanced video stream, generating decoded video information based on the base video stream and the enhanced video stream, and outputting the decoded video information.
