The present invention relates to a selective playback control method of an optical disc, and in particular, unnecessary songs are excluded in accordance with a user's wishes when playing an optical disc in which a plurality of programs are recorded in track units or recording to an arbitrary other recordable recording medium. The present invention relates to a selective playback control method of an optical disc, so that only necessary songs can be played or recorded in a recorded state.

Now, with the development of 'video disc' which is a composite medium of video and audio, it has been able to create a new type of software called visual music, and it is a complete system that works as a single system by combining audio and video. With the birth of / V equipment, it became a full-fledged A / V era where video and audio coexist.

As the A / V era begins in earnest, the public's attention to pure audio culture that presupposes only auditory appreciation has shifted to the A / V culture where audio-visual coexists. As a leader of the era, it is noted that an optical disc player such as a laser disc player (LDP), which arbitrarily reads a plurality of program (e.g., video music) information recorded in track units on an optical disc and reproduces a video signal and an audio signal, is attracting attention. Can be.

Such an optical disc player is provided with various service functions to provide convenience to the user. As an example of such a service function, a random play function for randomly playing (sometimes repeatedly playing) a plurality of program information recorded on an optical disc is provided. There is a shuffle function that allows a plurality of program information recorded on the optical disc to be reproduced randomly, and there is no program function that selects only a desired song.

However, when the number of songs to be listened to or recorded on the optical disc player containing a plurality of programs (for example, music) is larger than the songs to be excluded, it is not possible to specify a song that is not to be listened to or watched in the shuffle mode or the random play mode. There is discomfort.

In addition, if there are only a few songs to be excluded from the total recorded songs, it is good to be able to set the songs to be excluded, but there is no such function at present, and only the program to listen to or record in the program mode is currently set.

For example, when recording audio information recorded on a compact disc onto a cassette tape, or recording video and audio information recorded on a laser disc on a VTR tape, when recording reaches a portion of a song that you do not want to record, the recording stops at that position. It is inconvenient to restart the recording operation after jumping to the song position recorded in the track next to the track in which the track which is not desired to be recorded is recorded.

Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to play or record only a desired program in a state of excluding unwanted programs according to a user's mode selection among a plurality of programs recorded in track units on an optical disc. It is to provide a selective playback control method of an optical disk to enable.

According to a preferred embodiment of the present invention, the memory means is allocated to the TOC / lead-in information storage area, the desired music information storage area, and the excluded music information storage area.

The second step includes storing all the song information recorded in the TOC / lead-in area of the optical disc in the TOC / lead-in information storage area in the memory means as the program mode is selected; In addition to displaying the OSD text indicating the program mode on the monitor, and sequentially displaying all the information stored in the TOC / lead-in information storage area of the memory means and playing or recording / recording according to a user's selection key operation. The desired song is selected and stored in the desired song information storage area in the memory means.

On the other hand, the third process includes storing all the song information recorded in the TOC / lead-in area of the optical disc in the TOC / lead-in information storage area in the memory means as the exclusion song designation mode is selected; Displaying all the information stored in the TOC / lead-in information storage area of the memory means in addition to displaying an OSD character indicating the exclusion song designation mode on the monitor; According to a user's selection key operation, an exclusion song to be excluded from the playback or recording / recording operation is selected and stored in the exclusion song information storage area in the memory means.

According to the present invention configured as described above, when the user selects the program mode or the exclusion song designation mode, the OSD character indicating the currently set mode is displayed on the monitor and TOC / lead information of the optical disc stored in the memory means is displayed. When the desired song or exclusion song, which is displayed and selected by the user, is all stored in the memory means, the playback or recording / recording operation is performed according to the operation command signal keyed in based on the stored information.

In the figure, reference numeral 34 denotes a microcomputer for controlling the overall operation of the optical disc player to which the present invention is employed.

A selective playback control method for an optical disc according to an embodiment of the present invention will be described below based on the device configured as described above.

In the embodiment of the present invention, the optical disc player is described as having a monitor for a screen display.

In the flowchart of FIG. 4, once the user turns on the power of the laser disc player using the key input means 30 in step 41, the microcomputer 34 performs the number of operations of the mode selection key 30a. In step 41, the microcomputer 34 controls the general operation to be performed in step 42 when the mode selection key 30a is not operated. Here, the general operation is, for example, once the play command signal is input from the key input means 30, under the control of the microcomputer 34, the servo circuit unit 14 rotates the spindle motor 10 at constant speed and the optical pickup 12 ) Is moved to the TOC / lead-in area of the optical disc D to read the track number, the track reproduction absolute time, and the like for each program information recorded on the optical disc D, and the read information is stored in the memory means 32. In the TOC / lead-in information storage area. Thereafter, playback and recording / recording operations for the program selected by the key input means 30 are performed based on the information rules stored in the TOC / lead-in information storage area of the memory means 32. In this case, In addition, the program does not want the user to play or record, so you have to set it manually.

However, if the mode selection key 30a is operated once in step 41, the microcomputer 34 determines whether the mode selection key 30a is operated once again within a predetermined time.

As a result of the determination, when only one operation of the mode selection key 30a is finished, the microcomputer 34 recognizes the program mode that designates the current desired song in step 44. Accordingly, all the information (e.g., track number, track) recorded in the TOC / lead-in area of the optical disc D is stored in the TOC / lead-in information storage area in the memory means 32 under the control of the microcomputer 34 in step 45. Playback absolute time, etc.) are stored.

Subsequently, in step 46, under the control of the microcomputer 34, the OSD processing unit 28 processes predetermined OSD text data indicating the current program mode, and the video decoder 24 displays the image on the monitor 26 through FIG. The predetermined OSD character as shown in a) is displayed. Then, all the information stored in the TOC / lead-in information storage area of the memory means 32 is signal-processed by the OSD processor 28 under the control of the microcomputer 34, and then monitor 26 through the video decoder 24. On the lower part of the OSD text indicating, for example, the program mode. At this time, a selection mark such as e.g. is indicated at the front of the first title among the titles displayed on the monitor 26.

Accordingly, in step 47, the user selects a desired song by using the cursor movement key 30b and the selection key 30c in the key input means 30, and the selected desired song information is stored in the memory means 32 in step 48. Are stored sequentially in the desired song information storage area. Thereafter, when the user presses the end key 30d in the key input means 30 in step 49, the microcomputer 34 releases the program mode in step 50.

On the other hand, if the operation of the mode selection key 30a is performed once more within the predetermined time in step 43, then control proceeds to step 51, and the microcomputer 934 recognizes the current exclusion song designation mode. Under the control of the microcomputer 34, all the information recorded in the TOC / lead-in area of the optical disc D is stored in the TOC / lead-in information storage area in the memory means 32. Subsequently, in step 53, under the control of the microcomputer 34, the OSD processing unit 28 processes the predetermined OSD text data indicating that the current exclusion song designation mode is present, and on the monitor 26 through the video decoder 24. As shown in Fig. 5B, a predetermined OSD character is displayed. Then, all the information stored in the TOC / lead-in information storage area of the memory means 32 is signal-processed by the OSD processor 28 under the control of the microcomputer 34, and then monitor 26 through the video decoder 24. On the lower part of the OSD text indicating, for example, the exclusion song designation mode. At this time, a selection mark such as e.g. is indicated at the front of the first title among the titles displayed on the monitor 26.

Accordingly, in step 54, the user selects a song to be excluded using the cursor movement key 30 and the selection key 30c in the key input means 30 as in step 47. Information on the selected excluded music is stored in the excluded music information storage area in the memory means 32 in step 55 in sequence. Thereafter, when the user presses the end key 30d in the key input means 30 in step 56, the microcomputer 34 releases the exclusion song designation mode in step 57. FIG.

Then, in step 58, the microcomputer 34 at the key input means 30 is based on the information stored in the TOC / lead-in information storage area, the desired music information storage area, and the excluded music information storage area in the memory means 30. According to various operation command signals (for example, shuffle command signal, random play command signal, recording / record command signal, etc.), only the song that is desired to be played is excluded while the song is not played. It controls the recording so that only the desired song is recorded while unnecessary songs are excluded. In other words, the servo circuit unit 14 is controlled according to the position detection signal applied from the position detecting unit 18 so that unnecessary tracks are jumped to move the optical pickup 12 to a desired track so that playback or recording / recording operations are performed. do.

In addition, this invention is not limited only to the above-mentioned embodiment, It can implement by modifying and modifying within the range which does not deviate from the summary of this invention. For example, in the above-described embodiment, a predetermined OSD character is displayed on the monitor while the optical disc player is provided, but in the case where the monitor is not provided, the program mode or the fluorescent display is installed on the fluorescent display tube installed in the front control panel of the optical disc player. The OSD text indicating the exclusion song designation mode and all the songs contained in the optical disc may be sequentially displayed to be selected by the user.

In addition, in the above-described embodiment, the mode selection key is operated once to enter the program mode, and the second operation is set to the exclusion song designation mode. However, the mode selection key and the exclusion song designation mode key may be provided separately.

According to the present invention as described above, when the user sets the program mode or exclusion song designation mode to selectively input any song according to the mode, only the songs necessary in the state of excluding unnecessary songs during playback or recording / recording operation are excluded. This playback or recording not only eliminates the hassle of resetting settings, but also has the advantage of enhanced product specifications.
