Presentation of media content
First Claim
1. An information storage medium on which video data are recorded, comprising:
- a plurality of clips that are recording units in which the video data are stored; and
text data for subtitles which are recorded separately from the plurality of clips and overlappable with an image according to the video data and then outputtable, the text data including data for providing subtitles in at least one language.

Abstract
A media services interface for use in a readable medium playback device enables synchronization of disparate media playback, network directed playback of media, media playback control via displayed html/javascript file, logging of consumer identifier, media identifier, and playback device identifier in a cookie or log file. The media services comprises a command handler, a properties handler, an event generator, a cookie manager, a navigator state module, an identifier engine, an initialization module, and a bookmark manager. The command handler executes commands received from a connected network, a displayed html/javascript file, etc. The properties handler provides information relating to system states in response to queries including the status of any network connections. The event generator generates events in response to predetermined system occurrences. The cookie manager records information for later reading including the tracking of consumer identifier, playback device identifier, and readable medium identifier triples. The navigator state module maintains information regarding the state of the playback device and the interaction with the readable medium. The identifier engine carries out determination of the identity of the readable medium. The initialization module controls system initialization. The bookmark manager generates bookmarks which preserve positions in the playback of the readable medium for later recall. Network sources can provide media content and issue commands which synchronize the playback of both network and readable medium originated content over multiple playback devices through the use of the synchronization abilities of the media services.

1. An information storage medium on which video data are recorded, comprising:
- a plurality of clips that are recording units in which the video data are stored; and
text data for subtitles which are recorded separately from the plurality of clips and overlappable with an image according to the video data and then outputtable, the text data including data for providing subtitles in at least one language. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)
- a plurality of clips that are recording units in which the video data are stored; and
-
14. A reproducing apparatus which reproduces data from an information storage medium on which video data is recoded, the video data being coded and divided into clips that are recording units and recorded in a plurality of clips and on which text data for subtitles that are formed with data of a plurality of languages and are overlappable as graphic data with an image based on the video data, the text data being recorded separately from the clips, the reproducing apparatus comprising:
- a data reproducing unit which reads data from the information storage medium;
a decoder which decodes the coded video data;
a renderer which converts the text data into graphic data;
a blender which overlays the graphic data with the video data to generate an image;
a first buffer which temporarily stores the video data; and
a second buffer which stores the text data. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
- a data reproducing unit which reads data from the information storage medium;
-
30. A recording apparatus which records video data on an information storage medium, comprising:
- a data writer which writes data on the information storage medium;
an encoder which codes video data;
a subtitle generator which generates subtitle data addable to the video data;
a central processing unit (CPU);
a fixed-type storage; and
a buffer, wherein the video data is stored in the fixed-type storage after the encoder divides video images into clips that are recording units and compression encodes the clips, wherein the subtitle generator generates subtitle data for a plurality of languages in the form of a text, the subtitle data being reproducible together with an image based on the video data and stored in the fixed-type storage, wherein the buffer temporarily stores the data stored in the fixed-type storage, wherein the data writer records the coded video data and subtitle data that are temporarily stored in the buffer on the information storage medium, and wherein the CPU controls encoding of the video data, recording the coded video data and the subtitle data in respective separate areas on the information storage medium. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
- a data writer which writes data on the information storage medium;
-
43. A method of reproducing data stored on an information storage medium, comprising:
- reading audio-visual (AV) data and text data;
rendering subtitle image data from the text data;
decoding the AV data and outputting decoded AV data; and
blending the subtitle image data and the decoded AV data. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50)
- reading audio-visual (AV) data and text data;

51. A reproducing apparatus comprising:
- a reading section which reads audio-visual (AV) data, text data, and font data;
a decoder section which decodes the AV data and outputs moving picture data;
a rendering section which renders subtitle image data from the text data; and
a blending section which synthesizes the moving picture data with the subtitle image data. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58)
- a reading section which reads audio-visual (AV) data, text data, and font data;
-
59. A reproducing apparatus comprising:
- a reading section which reads text data and font data;
a rendering section which renders subtitle image data from the text data;
an outputting section which outputs the subtitle image data; and
an input receiving section which receives an input to subtitle data for a next line so as to control the output time of the subtitle data. - View Dependent Claims (60)
- a reading section which reads text data and font data;
-
61. A data recording and/or reproducing apparatus comprising:
- a storage section;
an encoder which codes audio-visual (AV) data to yield coded AV data;
a subtitle generator which generates renderable text data for subtitles;
a data writer which writes the coded AV data and the renderable text data onto the storage section;
a reading section which reads the coded AV data and the rederable text data;
a decoder section which decodes the coded AV data so as to yield moving picture data;
a rendering section which renders subtitle image data from the renderable text data; and
a blending section which synthesizes the moving picture data with the subtitle image data so as to yield blended moving picture data.
- a storage section;
