TH78593A - Methods and devices to duplicate the storage media that stores metadata to provide additional search functionality. - Google Patents

Abstract

DC60 Methods and Devices Reproducing the storage media used to store metadata. Will be made for The function of the search is added. By using various search keywords With audio-visual (AV) data, the device contains a search unit for searching scenes matching the search keyword. Using the search function Add it to the AV data by means of a metadata that contains information of a search keyword. This is a minimum for each scene of the AV data and a duplicate that is used to reproduce the AV data that matches at least one of the scenes. Discoverable by search set Metadata contains information. Of entry points and / or duration, angles, and more for each scene, so additional searching can be This can be done by using a large number of search keywords. Moreover, search results can be duplicated according to Scenario various And an additional search function will be provided for the title of the movie. Support a certain number of corners or a number of playing paths. Moreover This metadata can be created in different languages, allowing additional search functionality to be implemented in different languages. Methods and media replication devices that store metadata. Will be made for The function of the search is added. By using various search keywords With audio-visual (AV) data, the device contains a search unit for searching scenes matching the search keyword. Using the search function Add it to the AV data by means of a metadata that contains information of a search keyword. At least for the sun, each scene of the AV data and the recursion used to reproduce the AV data that matched at least one scene. Discoverable by search set Metta data will contain information Of entry points and / or duration, angles, and more for each scene, so additional searching can be This can be done by using a large number of search keywords. Moreover, search results can be duplicated according to Scenario various And an additional search function will be provided for the titles of movies that Support a certain number or a certain number of playing paths. Moreover This metadata can be created in different languages, allowing additional search functionality to be implemented in different languages.

Claims (5)

The replication device reproduces audio-visual (AV) data stored on storage media. The device consists of: 1. A search unit that finds scenes matching the search keywords by applying a search function to the AV data, comparing it to metadata containing at least one search keyword for each AV scene; and 2. A replication unit that reproduces the AV data matching at least one scene found by the search unit. 2. A device as defined in Claim 1 where metadata is defined for each scene. 3. A device as defined in Claim 1 where the replication unit finds the starting position of at least one found scene using an input point representing the starting position of at least one found scene. 4. A device as defined in Claim 1 that includes a user interface, which receives search keyword input from the user and displays the search results for each search keyword. 5. A device as defined in Claim 4 where the search results are displayed simultaneously. 6. A device as defined in Claim 1 where the enhanced search function is used when the movie title is reproduced. 7. A device as defined in Claim 1 where the enhanced search function is used when AV data is reproduced along the author-defined primary playback path and is not used when AV data is reproduced along the user-defined secondary or co-recorded playback path. 8. A device as defined in Claim 4 where, when a scene is found, the reproducer displays the found scene on the user interface and receives information on the selection of a particular found scene by the user, and subsequently reproduces the AV data corresponding to the selected scene. 9. A device as defined in Claim 8 where the reproducer reproduces AV data corresponding to the scene preceding or following the selected scene based on user input. 10. A device as defined in Claim 4 where, when a scene is found, the reproducer will... Reproduce AV data sequentially based on discovered scenes. 1 1. The device as specified in Claim 4, where AV data supports a number of angles, and the reproducer reproduces AV data corresponding to a given angle or user input angles, using angle-related information included in the metadata. 1 2. The method for reproducing AV data stored on the storage medium, where such method shall consist of searching for scenes that match the search keywords, applying the search function to the AV data, and comparing it to metadata containing at least one search keyword information for each AV data scene; and reproducing AV data corresponding to the discovered scenes. 1 3. The method as specified in Claim 12, where metadata is defined for each scene. 1 4. The method as specified in Claim 12, where the AV data reproduction shall consist of finding the starting position of at least one discovered scene, using the input point that represents the position. 1. The method specified in Claim 12, which involves receiving the user's input search keywords and displaying the search results for those keywords. 1. The method specified in Claim 15, which displays the search results concurrently with each thumbnail. 1. The method specified in Claim 12, which allows the additional search function to be enabled when the movie title is reproduced. 1. The method specified in Claim 12, which allows the additional search function to be enabled when AV data is reproduced along the author-defined primary playback path and to be disabled when AV data is reproduced along user-defined secondary or companion playback paths. 1. The method specified in Claim 12, once a scene is found, the AV data reproduction involves displaying the found scene on the user interface and receiving the user's selection of one of the found scenes. and the reproduction of AV data that matches the selected scene. 2.0. The method as specified in Claim 19, where the reproduction of AV data shall consist of the reproduction of AV data that matches the scene preceding or following the selected scene based on the user input. 2. 1. The method as specified in Claim 12, where, once a scene is discovered, the AV data reconstruction will continue by reconstructing AV data that consecutively corresponds to the discovered scene. 2. 2. The method as specified in Claim 12, where, when AV data supports a certain number of angles, the AV data replication will then be performed by replication of AV data that matches the specified angles, or the angles that are user input, using the angle information included in Metadata 2. 3. An information storage medium consisting of several layers that manage the structure of the audio-visual (AV) data recorded on it; consisting of one or more clips that constitute the AV data recording, with each clip being used as an object containing the AV clip stream for the AV data, and clip information used as attributes corresponding to the AV data; one or more playlists that reproduce the AV data, with each playlist containing a set of playlists corresponding to the playback ranges of the various clips; and metadata generated for each playlist to provide added search functionality to the AV data, where the metadata is defined scene by scene and contains at least one search keyword information to be used for each scene. When a search keyword is input by the user, AV data corresponding to one or more scenes that match the search keyword is reproduced. 4. The media stores the information as specified in claim 23, where the metadata shall include information indicating the starting position and time period of the scene repetition. 5. The information media as specified in Claim 23 shall include at least one search keyword representing the type of scene, one or more search keywords representing one or more characters appearing in each scene, one or more search keywords representing one or more actors/actresses playing the corresponding characters, and search keywords representing search criteria established by the Creator.
