## Abstract

An apparatus and method for reproducing a storage medium that stores metadata are provided for an enhanced search function using various search keywords of audio-visual (AV) data. The apparatus includes: a search unit for searching for scenes matching a search keyword by conducting an enhanced search function on the AV data with reference to metadata which contains information regarding at least one search keyword for each of the scenes of the AV data; and a reproducing unit for reproducing the AV data corresponding to at least one scene found by the search unit. The metadata may include information regarding an entry point and/or duration, angles, etc. of each scene. Hence, the enhanced search can be conducted using various search keywords. Further, search results can be reproduced according to diverse scenarios, and the enhanced search function can be provided for movie titles that support multiple angles or multiple paths. Moreover, metadata can be created in multiple languages, thereby enabling the enhanced search function to support multiple languages.

## Claims

### Claim 1

A reproducing apparatus which reproduces audio-visual (AV) data stored on an information storage medium, the apparatus comprising:
a search unit searching for scenes matching a search keyword by conducting an enhanced search function on the AV data with reference to metadata which contains information regarding at least one search keyword for each of the scenes of the AV data; and
a reproducing unit reproducing the AV data corresponding to at least one scene found by the search unit.

### Claim 2 (depends on 1)

The apparatus as claimed in claim 1, wherein the metadata is defined for each of the scenes.

### Claim 3

The apparatus as claimed in claim, 1, wherein the reproducing unit finds a start position of the at least one found scene using an entry point indicating the start position of the at least one found scene.

### Claim 4 (depends on 1)

The apparatus as claimed in claim 1, further comprising a user interface receiving the search keyword input by a user and displaying search results for the search keyword.

### Claim 5 (depends on 4)

The apparatus as claimed in claim 4, wherein the search results are displayed together with respective thumbnails.

### Claim 6 (depends on 1)

The apparatus as claimed in claim 1, wherein the enhanced search function is enabled when a movie title is reproduced.

### Claim 7 (depends on 1)

The apparatus as claimed in claim 1, wherein the enhanced search function is enabled when the AV data is reproduced along a main playback path defined by an author and is disabled when the AV data is reproduced along a side playback path defined by a user.

### Claim 8 (depends on 4)

The apparatus as claimed in claim 4, wherein, when there are found scenes, the reproducing unit displays the found scenes on the user interface, receives information regarding the selection of one of the found scenes by the user, and reproduces the AV data corresponding to the selected scene.

### Claim 9 (depends on 8)

The apparatus as claimed in claim 8, wherein the reproducing unit reproduces the AV data corresponding to the scene immediately before or after the selected scene based on the user's input.

### Claim 10 (depends on 4)

The apparatus as claimed in claim 4, wherein, when there are found scenes, the reproducing unit sequentially reproduces AV data corresponding to the found scenes.

### Claim 11 (depends on 4)

The apparatus as claimed in claim 4, wherein, when the AV data supports multiple angles, the reproducing apparatus reproduces AV data corresponding to a predetermined angle or an angle input by the user using information regarding angles included in the metadata.

### Claim 12

A method of reproducing AV data stored in an information storage medium, the method comprising:
searching for scenes matching a search keyword by conducting an enhanced search function on the AV data with reference to metadata which contains information regarding at least one search keyword for each of the scenes of the AV data; and
reproducing the AV data corresponding to a scene found.

### Claim 13 (depends on 12)

The method as claimed in claim 12, wherein the metadata is defined for each of the scenes.

### Claim 14 (depends on 12)

The method as claimed in claim 12, wherein the reproducing of the AV data comprises finding a start position of the at least one found scene using an entry point indicating the start position of the at least one found scene.

### Claim 15 (depends on 12)

The method as claimed in claim 12, further comprising receiving the search keyword input by a user and displaying search results for the search keyword.

### Claim 16 (depends on 15)

The method as claimed in claim 15, wherein the displaying of the search results comprises displaying the search results together with respective thumbnails.

### Claim 17 (depends on 12)

The method as claimed in claim 12, wherein the enhanced search function is enabled when a movie title is reproduced.

### Claim 18 (depends on 12)

The method as claimed in claim 12, wherein the enhanced search function is enabled when the AV data is reproduced along a main playback path defined by an author, and is disabled when the AV data is reproduced along a side playback path defined by a user.

### Claim 19 (depends on 12)

The method as claimed in claim 12, wherein, when there are found scenes, the reproducing of the AV data further comprises displaying the found scenes on a user interface, receiving information regarding the selection of one of the found scenes by the user, and reproducing the AV data corresponding to the selected scene.

### Claim 20 (depends on 19)

The method as claimed in claim 19, wherein the reproducing of the AV data further comprises reproducing the AV data corresponding to the scene immediately before or after the selected scene based on the user's input.

### Claim 21 (depends on 12)

The method as claimed in claim 12, wherein, when there are found scenes, the reproducing of the AV data further comprises sequentially reproducing the AV data corresponding to the found scenes.

### Claim 22 (depends on 12)

The method as claimed in claim 12, wherein, when the AV data supports multiple angles, the reproducing of the AV data further comprises reproducing AV data corresponding to a predetermined angle or an angle input by the user using information regarding angles included in the metadata.

### Claim 23

An information storage medium formed with multiple layers to manage a data structure of audio-visual (AV) data recorded thereon, comprising:
one or more clips that are recording units of AV data, each clip being implemented as one object including a clip AV stream for AV data and clip information for attributes corresponding to the AV data;
one or more playlists that are reproducing units of AV data, each playlist including a set of playitems corresponding to reproduction intervals of the clips; and
metadata created for each playlist for providing an enhanced search function on the AV data;
wherein the metadata is defined scene by scene, and comprises information regarding at least one search keyword to be applied to a corresponding scene, and when a search keyword is input by a user, AV data corresponding one or more scenes matching the search keyword is reproduced.

### Claim 24 (depends on 23)

An information storage medium as claimed in claim 23, wherein the metadata further comprises information regarding a start location and a reproduction duration time of the corresponding scene.

### Claim 25 (depends on 23)

The information storage medium as claimed in claim 23, wherein the search keyword includes at least one of a search keyword regarding a scene type, a search keyword regarding one or more characters appearing in the corresponding scene, a search keyword regarding one or more actors/actresses playing the corresponding characters, and a search keyword regarding a search criterion which a producer defines.
