A technique for presenting text information to service users with enhanced visual effects so that the text information makes a strong impression on the users. A video creation server includes an acquisition section configured to acquire material data including one or both of text data and a still image, and a control section configured to acquire a script code editable by a user and to create moving-image data having the material data embedded into each frame of previously defined moving-image data such that the material data moves within the previously defined moving-image data in accordance with the script code.

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 capturing control apparatus that enables a user to recognize a transparency of OSD for recording. A system controller sets a transparency of OSD superimposed on a captured LV image and sets whether or not to record the captured image in a state combined with the OSD, as an image file. The OSD is displayed in a state superimposed on the LV image at a transparency of OSD for display, regardless of a setting concerning recording of the image file, and in a case where it is set to record the LV image in the state combined with the OSD, the OSD is displayed according to a specific operation, in a state superimposed on the LV image, at a transparency of OSD for recording, regardless of the transparency of OSD for display.

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, and a maximum luminance information acquirer that acquires, in a case where a dynamic range of luminance of the video stream is a second dynamic range that is wider than a first dynamic range, maximum luminance information indicating the maximum luminance of the video stream from the video stream. The decoding system also includes an outputter that outputs the decoded video information and the maximum luminance information. Where the dynamic range of luminance of the video stream is expressed by the maximum luminance of all pictures in the video stream as the maximum luminance information, the outputter outputs the decoded video information, along with the maximum luminance information indicating the maximum luminance of all pictures in the video stream.

An information processing apparatus is provided that includes a playback unit to play back music data, an analysis unit to analyze a feature of a relevant image of the music data, an image correction unit to perform image correction with use of any of a plurality of correction types, a storage unit to store one or more than one image, a selection unit to select a correction type corresponding to the feature of the relevant image analyzed by the analysis unit from the plurality of correction types, a correction control unit to cause the image correction unit to perform image correction of an image stored in the storage unit with use of the correction type selected by the selection unit, and an output unit to output the image corrected by the image correction unit.

A data processing apparatus includes a text acquisition mechanism acquiring texts to be used as keywords which will be subject to audio retrieval, the texts being related to contents corresponding to contents data including image data and audio data; a keyword acquisition mechanism acquiring the keywords from the texts; an audio retrieval mechanism retrieving utterance of the keywords from the audio data of the contents data and acquiring timing information representing the timing of the utterance of the keywords of which the utterance is retrieved; and a playback control mechanism generating, from image data around the time represented by the timing information, representation image data of a representation image which will be displayed together with the keywords and performing playback control of displaying the representation image corresponding to the representation image data together with the keywords which are uttered at the time represented by the timing information.

Applying a presentation timestamp to an element of a sequence of sub-titles. A minimum presentation timestamp T.sub.MIN of an element of a sequence of sub-titles N is initialized. The presentation timestamp T(N) of the new element of a sub-title sequence N is compared with the minimum presentation timestamp for sub-titles T.sub.MIN. The minimum presentation timestamp for sub-titles T.sub.MIN is applied to the element of a sequence of sub-titles N if the presentation timestamp T(N) of the new sub-titles element is prior to the minimum presentation timestamp for sub-titles T.sub.MIN. The minimum presentation timestamp for sub-titles T.sub.MIN for an element of a sequence of sub-titles N+1 is calculated as a timestamp posterior to the presentation timestamp T(N) of the new sub-titles element.

Creating a sub-titles stream or file composed of sub-titles elements. For each sub-titles element in said sub-titles elements, a sub-titles element is inserted into the sub-titles stream or file, at least one end-of-block condition related to a mode of presentation of sub-titles is verified, and a datum representative of an end of a block according to the mode of presentation of sub-titles is inserted into the sub-titles stream or file upon satisfying said at least one end-of-block condition. A sub-titles stream or file may be presented on a terminal of a user by selecting on the terminal a mode of presentation of sub-titles, reading a sub-titles block associated with the mode of presentation in the stream or file, and presenting on the terminal the at least one sub-titles block according to the mode of presentation.

There is provided an information processing apparatus, an information processing method, a recording medium, a playback apparatus, a playback method, and a program that are designed to prevent an unnatural change in luminance during random access. The information processing apparatus according to one aspect of the present technology generates dynamic metadata including information regarding luminance of a picture, and encodes HDR video data such that the dynamic metadata is added to each picture serving as a random access point. For example, the dynamic metadata can be allowed to be added to the first picture of a GOP, the first picture serving as the random access point during fast-forward playback/rewind playback or cueing playback. The present technology can be applied to a Blu-ray (registered trademark) Disc player.

A playlist file for controlling playback of a VOB stream file is recorded in a recording medium. A CombiExt_for_Cell( ) and Combi( ) indicating combinations of elementary streams that each can be played at the same time in the same Cell are described in the playlist file. Elementary streams that can be played at the same time as SDR video are listed in the CombiExt_for_Cell( ), and elementary streams that can be played at the same time as HDR video are listed in Combi( ). The number of elementary streams of a predetermined type listed in CombiExt_for_Cell( ) and the number of elementary streams of the predetermined type listed in Combi( ) are each equal in the same Cell.
