The recording medium according to the present invention is characterized by having an audio area in which audio tracks are recorded and a predetermined area for storing reproduction related information for reproducing only a representative portion representing an audio track designated by a user.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the audio highlight part recording / reproducing method and apparatus according to the present invention and a recording medium for storing the additional information therefor.

In the present invention, a portion of an audio track is designated as a highlight part and used as a representative portion of the audio track. This highlight part may be referred to as a representative part and may be used in conjunction with a visual menu.

That is, as shown in FIG. 2, each audio track has its own highlight part. Each audio track can have highlight parts of different lengths and of different lengths. Unlike playback with traditional intro features, users can designate the part they want as a highlight part, making it easier for the user to determine whether the audio track is the audio track they want when the highlight part is played. To be.

This highlight part may be used in conjunction with the image menu as shown in FIGS. 3A to 3C. The image menu may have link information for activating the reproduction of the highlight part. When the corresponding connection information is validated by the user's selection, the highlight part of the corresponding audio track is played so that the user can easily determine whether the audio track is the desired audio track.

3A illustrates an example in which connection information of a highlight part of each audio track is implemented in the image menu, and the highlight part of the first audio track is reproduced by the connection information of the highlight part of the first audio track.

3B illustrates a case in which highlight parts of all tracks can be played through the image menu. When a selection command (Highlight in a menu) is input by a user to input all highlight parts, highlight parts of all audio tracks are displayed. Are played sequentially. Even if there is a track for which a highlight part is not assigned, the track for which the highlight part is not specified can be replaced with the highlight part by playing the first part for a predetermined time like the existing intro function.

3C, when the playback of a highlight part of a playlist composed of connection information of various audio tracks is enabled through the image menu, the highlight parts of all audio tracks included in the playlist are sequentially played. Also in this case, the track in which the highlight part is not designated among the tracks included in the playlist may play the first part for a predetermined time like the existing intro function, and may replace the highlight part.

On the other hand, in the DVD-Audio recording format, information on the track consists of several cells. Each cell stores information about several entry points included in the cell. An entry point is an information structure indicating that an event specified by the entry point may have an event at a timing designated by the entry point.

4A shows an example in which a track is composed of three cells, a highlight entry point is designated in a first cell, and a corresponding highlight part is finished in a second cell. Highlight part information related to reproduction of the highlight part is stored at an entry point included in a cell in the track information. Therefore, the playback apparatus starts playback from the data at the start timing specified by the highlight entry point and finishes playback at the end time specified by the highlight entry point.

FIG. 4B shows an example in which a playlist has two tracks, the first track consists of two cells, and the second track consists of three cells. Each track has a highlight part. In the structure shown in Fig. 4B, the highlight part information related to the reproduction of the highlight part of each track in the playlist is stored at an entry point included in the cell in the track information. Thus, the playback device plays back the highlight part of the first track connected to the playlist and then plays the highlight part of the second track.

In FIG. 5, which is a flowchart according to an embodiment of an audio highlight part recording method according to the present invention, when the highlight recording mode is set by the user (step S100), the track selected by the user is recorded / played back (step S101), The user designates a highlight start time at a portion that the user thinks to be a highlight start point (step S102). When the highlight start point is designated, the highlight part information is recorded in the corresponding track information (step S103), and the start point of the highlight part is recorded in the highlight part information. If the user does not specify the highlight start time in step S102, the track is continuously recorded or played (step S104).

If the user designates a specific point as an end point of the highlight part while performing recording / playback of the track after performing step S103 (step S105), after recording the highlight duration information in the recorded highlight part information (step S105); Step S106) The highlight recording mode ends. The highlight duration information indicates the length of time of the highlight part. If the user does not specify the highlight end point in step S105, the track is continuously recorded or played (step S107).

For example, in the case of the DVD-Audio recording format, the highlight part information becomes an entry point for a highlight part included in a cell corresponding to a timing designated as the highlight part, and in step S103 the highlight part is added to the entry point for the highlight part. The start time point information is recorded, and the highlight part duration information is recorded in the entry point for the highlight part in step S106.

Although the recording method illustrated in FIG. 5 illustrates specifying a highlight part while recording / reproducing a single track, the method may further include determining whether to specify a highlight part for the next track after performing step S106. By repeating steps S101 to S107, a highlight part can be designated continuously for a plurality of tracks recorded on the recording medium, and then playlist information consisting of connection information for connecting a plurality of tracks designated as the highlight part is generated. It may further comprise the step.

6 is a flowchart according to another embodiment of the audio highlight recording method according to the present invention, illustrating a method in which only a start point of a highlight part is designated and a duration is designated by a recording / reproducing apparatus.

When the highlight recording mode is set by the interface with the user (step S110), the track selected by the user is recorded / played back (step S111), and the start point of the highlight is designated at the portion that is considered to be the beginning of the highlight (S112). step). If the highlight start time is specified, the highlight part information is recorded in the information of the corresponding track (step S113), and the highlight recording mode ends. The start point of the highlight part is recorded in this highlight part information. If the user does not specify the start point of highlight in step S112, the track is continuously recorded / played (step S114).

In the case of the DVD-Audio recording format, the highlight part information becomes an entry point for a highlight part included in a cell corresponding to a specified timing of the highlight part, and the highlight part start time information is recorded in the entry point for the highlight part in step S113. do. The predetermined high-write duration information designated by the recording apparatus may be recorded at the entry point, or may be reproduced at the predetermined duration specified by the playback apparatus at the time of reproduction of the highlight part without recording the highlight duration information.

Also in the recording method shown in Fig. 6, after performing step S113, determining whether to designate a highlight part for the next track, and repeating steps S111 to S114 to the plurality of tracks recorded on the recording medium. For example, the highlight part may be continuously designated, and the method may further include generating playlist information including connection information connecting a plurality of tracks designated as the highlight part.

In FIG. 7, which is a flowchart according to an embodiment of the method for reproducing an audio highlight part according to the present invention, the highlight reproduction mode set in step S200 is, for example, in units of one desired audio track in association with the menu shown in FIG. 3A. This mode is to play the highlight part by the interface with the user. If the highlight playback mode is set, the playback apparatus analyzes the highlight part information of the track from the track information (step S201). Playback is started from the data of the portion indicated by the corresponding start time point information using the highlight part start time point information indicated by the analyzed highlight part information (step S202).

If the highlight part duration information is stored in the corresponding highlight part information, the data is played for the duration indicated by the highlight duration information from the data corresponding to the start of the highlight part (step S203), and the playback of the highlight part is stopped (step S203). Step S204). If the track is not played during the highlight duration in step S203, the highlight part of the track is continuously played (step S205).

If duration information is not recorded in the highlight part information in step S203, playback is stopped after the data corresponding to the start point of the highlight part is played for the duration specified by the playback apparatus.

In FIG. 8, which is a flowchart according to another embodiment of the method for reproducing an audio highlight part according to the present invention, the highlight reproducing mode set in step S210 is, for example, a recording medium by a user interface in association with the menu shown in FIG. 3B. This mode plays back the highlight parts of all tracks recorded on it. When the highlight play mode is set, the track part information of the first track is analyzed from the track information (step S211). The track is played back from the highlight part start timing indicated by the analyzed highlight part information (step S212).

It is determined whether the track has been played for the duration specified by the highlight duration information of the highlight part information (step S213). If playback of the track is completed for the duration, the playback of the highlight part of the track ends (step S214). Otherwise, the highlight part of the track is continuously played (step S215).

When playback of the highlight part of the track is finished in step S215, it is determined whether it is the last track included in the track information (step S216), and if the next track does not exist, the highlight playback mode ends. If the next track exists in step S216, the highlight part information of the next track is analyzed in the track information (step S217), and steps S212 to S215 are performed to play the highlight part duration of the track at the start of the highlight part of the track. do. Of course, when the highlight part duration information is not recorded in the highlight part information, playback is performed for a duration specified by the playback apparatus.

Here, in the mode in which the highlight parts of all tracks recorded on the recording medium are reproduced, there may be a track in which the highlight part is not designated among the tracks recorded on the recording medium. These tracks, like the existing intro function, play the first portion of a track for which no highlight part is specified, so that it replaces the highlight part, and the other tracks play the designated highlight part of each track.

9 is a flowchart according to another embodiment of a method for reproducing an audio highlight part according to the present invention. The highlight reproducing mode set in step S220 is, for example, a highlight part of a corresponding playlist in association with the menu shown in FIG. 3C. This mode is for playback. A playlist is a connection of several tracks with connection information. The highlight part information of tracks connected to the playlist is not stored in the cell in the track information as shown in FIG. It is stored at the entry point it contains.

When the highlight playback mode of the playlist is set, the playback apparatus analyzes the first track information included in the playlist (step S221). The highlight part information is analyzed from the analyzed track information (step S222), and the track is reproduced from data corresponding to the start point of the highlight part indicated by the highlight part information (step S223). It is determined whether the track has been played for the duration specified by the highlight duration information of the corresponding highlight part information (step S224), and if the highlight part of the track is finished playing for the duration, the playback of the highlight part of the track ends ( Otherwise, the highlight part of the corresponding track is continuously played (step S226).

After performing step S225, it is determined whether it is the last track included in the playlist (step S227), and if the next track does not exist in the playlist, that is, the track that has just finished playing the highlight part immediately before is the last of the playlist. In the case of a track, the highlight play mode of the playlist is terminated. If there is a next track included in the playlist in step S227, after analyzing information on the next track of the playlist (step S228), steps S222 to S226 are performed to perform the corresponding track at the beginning of the highlight part of the track. Play the highlight part for the duration of the track's highlight part. Of course, when the highlight part duration information is not recorded in the highlight part information, playback is performed for a duration specified by the playback apparatus.

Here, some tracks included in the playlist may have tracks for which the highlight part is not designated. These tracks play the first portion of the track just like traditional intro features. In other words, in the playlist highlight play mode, if there is a track that does not have a highlight part assigned to it, the first part of the track that is not designated is played. Play the highlight part.                     

In FIG. 10, which is a flowchart according to another embodiment of a method for reproducing an audio highlight part according to the present invention, when the highlight reproduction mode for a playlist is set (step S230), the highlight part of each track connected to the corresponding playlist is selected. Are continuously played back (step S231), and if a playback command for the track is input from the user before playing the highlight part of the track for the specified highlight part duration (step S232, step S233), the highlight part of the track Playback is stopped (step S234), and playback is performed from the beginning of the track to the end of the track (step S235). Of course, if the highlight part of the track is played for the duration of the highlight in step S232, the process proceeds to step S231 to play the highlight part of the next track. In addition, if the play command for the track is not input in step S233, the highlight part of the track is continuously played, and then the process proceeds to step S232 (step S236).

After performing step S235, it is determined whether it is the last track included in the playlist (step S237), and if it is not the last track, the next track of the playlist is selected (step S238), from the beginning of the track to the end of the track. The playback proceeds to step S235 to play, and if it is the last track, playback of the corresponding playlist is completed.

In the playback method illustrated in FIG. 10, the highlight part of each track connected to the corresponding playlist is played, and according to the user's playback command, the playback method plays back the entire section from the corresponding track to the last track when the playback command is input. And without performing step S238, play only the corresponding track at the point of time when the play command is input according to the play command of the user, and then terminate or proceed to step S231, where other tracks connected to the playlist may play only the highlight part. There may be more examples.

In FIG. 11, which is a flowchart according to another embodiment of a method for reproducing an audio highlight part according to the present invention, when a playlist highlight play mode is set (step S240), a highlight part of a specific track connected to the corresponding playlist is played. During operation (step S241), when a play command for the corresponding playlist is input from the user (step S242), the playlist highlight playback mode is stopped (step S243), and all tracks connected to the playlist, that is, the corresponding playback From the first track of the list to the end track of the playlist (S244). Of course, if there is no user's playback command for the playlist in step S242, the highlight part of the playlist is continuously played (step S245).
