BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying playback history information of a recorded program, and more particularly, to a method for displaying playback history information of a recorded program for providing information on the playback history of a program recorded on an optical disc.

Recently, as a recording medium for recording and storing high quality video data and high quality audio data for a long time, a DVD (Digital Versatile Disc) has been developed and commercialized. A DVD-RW capable of rewritable recording has been developed and used.

In the case of an optical disc capable of rewritable repetition such as the DVD-RW, a video title set (VTS) is used to transmit video / audio data provided from an external source such as a digital television broadcasting program or a camcorder through an optical disc recording / reproducing apparatus. A plurality of programs can be recorded separately, and video title set information (VTSI) is recorded for each title set in video management information (VMGI), that is, navigation information, of the corresponding optical disc. The recording state of each title set can be managed.

On the other hand, when the optical disc on which such a program is recorded is played back, the navigation information is searched to select a video title set of a program to be played back so that the video title set can be read out from the optical disc and played back.

However, in the case of playing an optical disc on which at least one program is recorded, it is difficult not only to check the reproduction history such as whether or not the video title set of the optical disc is played or the number of times of reproduction, but also to allow a plurality of users to write to one optical disc. In the case of recording the desired programs individually, it is difficult to sort the recorded programs individually for each user. Therefore, in the case of an optical disc containing a program that requires repetitive playback such as a language learning program, for example. There is a problem that the reproduction effect of a desired optical disc can be halved.

Accordingly, the present invention has been made in view of the above-described conventional circumstances, and an object thereof is to enable the playback history of a program recorded on an optical disc to be managed through navigation information so that the playback history of a program to be played back can be displayed. A method of displaying playback history information of a recorded program is provided.

Another object of the present invention is to provide a playback history information display method of a recorded program for managing a program recorded on an optical disc for each recorder so that the program can be displayed for each recorder when the list is searched for playback of the recorded program.

In order to achieve the above object, according to the present invention, generating playback history information in the navigation information for the video title set of the program recorded on the storage medium, and title for each video title set based on the playback history information And sorting and displaying the list, and updating the playback history of the video title set when full playback of the video title set is performed.

Hereinafter, the present invention configured as described above will be described in detail with reference to the accompanying drawings.

That is, Fig. 1 is a diagram showing the configuration of an optical disc recording / reproducing apparatus to which the reproduction history information display method of the present invention is applied.

As shown in FIG. 1, an optical pickup 12 for recording external input data on an optical disk 10 such as a DVD-RW capable of being repeatedly recorded or reading data contained in the optical disk 10, a tuner; Encoding and modulating external input data from the same external input source into a signal suitable for recording, generating and recording navigation information for reproduction control of the recording data, and reproducing the recording data read from the optical disc 10. Recording / reproducing system 14 which performs decoding and demodulation function, key input unit 16 which performs user key input for recording and reproducing optical disk 10, and programs recorded on the optical disk 10. The recording / reproducing operation of the memory 18 and the recording / reproducing system 14, in which recording user information for classifying by user is set and stored, is controlled. And a OSD generation unit 22 for generating graphics and characters for displaying the playback history, and a microcomputer 20 for controlling the playback history of the playback program and recording the playback history of the full-played program. .

The microcomputer 20 allows a recording user REC_USER to be designated for each video title set of a program recorded on the optical disc 10 by a selection operation of the key input unit 16, and whether or not playback is performed for each video title set (FULL_PLAY). ), The contents of the navigation information are set so that the number of playbacks (PLAY_TIME) can be recorded.

In addition, when there is a list inquiry for reproducing a video title set according to a plurality of programs recorded on the optical disc 10, the microcomputer 20 classifies each video title set for each recording user based on the navigation information. It is displayed on the title list, and the play status and the number of playbacks are displayed for each video title set in the title list. When the sorting function is turned off, a plurality of videos classified by a specific recording user are classified. The title sets are displayed in the order specified by the set number irrespective of whether they are played or not, and when the sorting function is ON, a plurality of video title sets classified by a specific recording user are displayed. Sort and display in least order.

In the microcomputer 20, when a specific video title set is played in full according to a playback function, the recording / playback system 14 is controlled so that navigation information of the optical disc 10 is reproduced for the corresponding video title set. And update the recording frequency.

4 is a flowchart illustrating an operation of generating playback history information in navigation information of an optical disc in the method of displaying playback history information of a recorded program according to the present invention, and FIG. 5 is a method of displaying playback history information of a recorded program according to the present invention. Is a flowchart for explaining an operation of displaying a reproduction history in accordance with the navigation information of an optical disc.

Hereinafter, a flowchart according to an embodiment of the present invention shown in FIG. 4 will be described in detail in parallel with the operation of the apparatus of FIG. 1.

First, a video / audio transport stream (TS) of a specific broadcast program tuned from a tuner is encoded into a program stream (PS) capable of recording on the optical disc 10 in the recording / reproducing system 14. The video recording operation is modulated and recorded on the optical disc 10 through the optical pickup 12 (step S10).

In this state, the microcomputer 20 determines whether the recording is finished (step S11), and if the recording is finished, it is determined whether the playback history function is applied by the user's key input unit 16 operation (step S12), If it is determined that the reproduction history function is not applied, general recording information of the video title set on which the recording is made is stored in the navigation information of the optical disc 10 (step S13).

However, if it is determined in step S12 that the playback history function is applied according to the user's manipulation of the key input unit 16, whether or not the division of the recording user is selected for the corresponding recorded video title set. It is determined (step S14).

As a result of the determination, when the microcomputer 20 determines that the classification of the recording user for the recorded video title set is selected according to a user operation of the key input unit 16, the plurality of preset presets in the corresponding optical disc recording / reproducing apparatus are performed. A list of recorded users is outputted so that one specific recorded user can be selected therefrom (step S15).

Accordingly, the microcomputer 20 may store the information of the recording user (REC_USER = BOA) in the recorded video title set information (VTS # 1_INFO) of the navigation information, as shown in FIG. The management information for managing whether or not the set is played (FULL_PLAY = YES) and the number of times of play (PLAY_TIME = 8) can be stored (step S16).

Next, a flowchart according to an embodiment of the present invention shown in FIG. 5 will be described in detail in parallel with the operation of the apparatus of FIG. 1.

First, in a state where a plurality of video title sets are stored on the optical disc 10, the microcomputer 20 requests a list of programs recorded by key input of the key input unit 16 (step S20).

Accordingly, the recording / reproducing system 14 reads the navigation information of the optical disc 10 through the optical pickup 12 (step S21). In the microcomputer 20, the reproduction history information is added to the navigation information. It is judged whether or not it is stored (step S22), and if it is determined that the playback history information is not recorded, the general video title set is reproduced (step S23).

However, if the microcomputer 20 determines that the playback history information is recorded in the navigation information of the optical disc 10 in the determination result of step S22, the recording user's information on each video title set is included in the playback history information. It is judged whether or not division is made (step S24).

As a result of the determination, when it is determined that the recording users for each video title set are not distinguished from the reproduction history information, whether the sorting indication of the plurality of video title sets based on the reproduction history information is turned on. It is judged (step S25).

As a result of the determination, when it is determined that the sorting display for the plurality of video title sets is turned on, each video title set for each playback title and the number of playbacks is determined by the character and graphic display operation through the OSD generator 22 without distinction of the recording user. The title list is sorted for and displayed on the display screen (step S26).

However, when it is determined that the sorting display for the plurality of video title sets is OFF according to the determination result of step S25, the recording users are not distinguished and each video title set is irrelevant regardless of whether or not it is played. Are displayed without sorting in the order of numbers of the video title sets given in the recording order (step S27).

In the meantime, when the microcomputer 20 determines that the recording users are divided for the plurality of video title sets of the optical disc 10, the microcomputer 20 displays the recording users in the recording user list as shown in FIG. 3A. A specific recording user is selected from among the plurality of recording users to be selected, and it is determined whether the sorting display of the plurality of video title sets based on the reproduction history information is turned on (step S28).

As a result of the determination, when it is determined that the sorting display for the plurality of video title sets is turned on, as shown in FIG. 3B by the text and graphic display operation through the OSD generator 22, the selected specific recording users are selected. The list of titles for each video title set is sorted and displayed on the display screen for each of the divided video title sets by the presence or absence of the playback (step S29).

However, if it is determined that the sorting display for the plurality of video title sets is OFF according to the determination result of step S28, play is performed for the video title sets divided by the selected recording users as shown in FIG. 3C. And irrespective of the number of playbacks, each video title set is displayed in the order of the number of video title sets given in the recording order (step S30).

In this state, the microcomputer 20 determines whether or not a key input of the key input unit 16 for playing a video title set of a specific program is performed among the plurality of video title sets displayed in the title list (step S31). If it is determined that a key input for reproduction of a specific program is performed, playback of the selected video title set is performed through the optical pickup 12 and the recording / reproducing system 14 (step S32).

Next, the microcomputer 20 determines whether or not the specific video title set to be reproduced has been played in full (step S33). Therefore, the micom 20 does not perform full playback on the video title set. If it is determined, the presence or absence of the reproduction of the navigation history of the navigation information and the number of reproductions are not updated (step S34).

However, when the microcomputer 20 determines that the full playback of the video title set to be reproduced has been performed in the determination result of step S33, if there is a title set that was first played in the playback history information of the navigation information, the play status is updated. (FULL_PLAY = YES), and if the number of times of reproduction is at least one or more times, the number of times of reproduction is updated (PLAY_TIME = 8) (step S35).

On the other hand, the present invention is not limited to the above-described typical preferred embodiments, but can be carried out in various ways without departing from the gist of the present invention, various modifications, alterations, substitutions or additions are common in the art Those who have knowledge will easily understand. If the implementation by such improvement, change, replacement or addition falls within the scope of the appended claims, the technical idea should also be regarded as belonging to the present invention.
