How to execute repeat function of video compact disc player

The present invention relates to a method of executing a repeating function of a video compact disc player, and more particularly, to a method of executing a repeating function of a video compact disc player capable of efficiently executing various repeating functions regardless of a version of a video compact disc. will be.

With the development of audio and video media, optical disc players for recording and reproducing video and audio data on semi-permanent optical discs have been developed.

Such an optical disc player reproduces an image and / or audio recorded on an optical disc and outputs it through a screen and / or a speaker, and has a higher signal-to-noise ratio than conventional image and / or audio reproducing apparatus, resulting in better image quality and / or Or it can reproduce the signal with sound quality, it does not generate noise due to irregular reproduction and modulation, very low distortion, no ghost and random access, so it is rapidly developed and widely distributed. There is a trend.

In addition, such an optical disk player includes a compact disk player (CDP), a laser disk player (LDP), a compact disk graphic player (CDGP), and a video compact disk player (VCDP: video compact disk player) has been developed and widely used. Also, recently, a digital video disk (DVD) using MPEG-2 moving picture compression technology and a digital video disk player for playing the same have been developed. It can record and play back gigabytes (GB) of data including moving images on a 12cm optical disc such as a CD, and it is also designed to be compatible to play current CDs and VCDs.

On the other hand, such an optical disc player is additionally provided with not only normal playback but also special playback functions. For example, there are repeat functions, playback control functions, memory playback, and image search.

Among them, the repetition function is a function of repeatedly playing a predetermined number of times for a predetermined section or all sections. In particular, the repeating function is a function frequently used when playing back a language disc.

On the other hand, there are two types of video compact discs (VCDs) used in video compact disc players, VCDs of version 1.1 and VCDs of version 2.0.

However, if the video compact disc player wants to repeat the above-described version 1.1 VCD and version 2.0 disc, the version 1.1 VCD can perform interval repeating and full-range repeating. Due to the playback control function, the user selects a desired function sequentially through the menu screen, so that only the section repetition for the section or track displayed on the menu screen is possible and the whole section cannot be performed.

Therefore, the present invention has been devised to solve such a problem in the related art, and an object of the present invention is to efficiently perform the interval repeating and the whole repeating function even for a VCD of version 2.0 in performing the repeating function in a video compact disc player. It provides a method of executing the repeat function of a video compact disc player.

According to a preferred embodiment of the present invention for achieving this object, a video compact disc player for efficiently executing the section repeat and full-range repeating functions regardless of the version of the video compact disc (VCD) played in the video compact disc player. In the repeating method, (A) read and store TOC (table of contents) data recorded in the lead-in area when the disc is loaded, read and store the VCD file data recorded in track 1, and then press key input. (B) executing playback when the playback key signal is input; and (c) determining whether a repeat key signal for one section for a predetermined section is input. Determining whether the player is in the playback control mode; and (d) the track currently being played if the current playback mode is the normal playback mode in step (c). Or repeating playback for the section and repeating playback of the currently playing entry area in the playback control mode; and (e) if the one-step repeat key signal is not input in step (c), Determining whether an input is made; (f) returning to step (c) if the all-time repetition key signal is not input in step (e); When a signal is input, it is determined whether the current play mode is the normal play mode or the play control mode. In the normal play mode, all the tracks of the disc being played are repeatedly played. In the play control mode, the displayed menus are sequentially displayed. Repeat playback, and (H) when the repeat play cancel key signal is input, cancel the repeat function and sequentially from the position where the repeat function is released. And a step of executing playback.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a video compact disc player for practicing the present invention.

As shown in FIG. 1, a video compact disc player for implementing the present invention includes a pickup and actuator unit 10, an RF (radio frequency) signal amplification and servo signal processing unit 20, a motor driver 30, and a key input unit ( 40, the microcomputer 50, the digital signal processor 60, the MPEG decoder 70, the audio signal processor 80, the video signal processor 90, the speaker 100, and the screen 110.

The pickup and actuator unit 10 executes an optical pickup from a disc loaded in a disc tray (not shown) and outputs an RF signal which is read accordingly.

In addition, the motor driving unit 30 drives the spindle motor (not shown) to rotate the disk, and drives the actuator unit 10 so that the pickup unit 10 performs optical pickup to read the data recorded on the disk to RF Output as a signal.

The RF signal amplification and servo signal processing unit 20 amplifies an RF signal provided from the pickup and actuator unit 10 and provides a servo control signal according to the signal to the motor driving unit so that the focus servo and the tracking servo are performed.

The digital signal processing unit 60 digitally processes the amplified RF signal provided from the RF signal amplification and servo signal processing unit 20, performs error detection and error correction, and outputs the result to the MPEG decoder 70.

The MPEG decoder 70 decodes an error corrected digital video signal and an audio signal provided from the digital signal processor 60 based on the MPEG compression format and outputs the decoded video signal to the video signal processor 90 and the audio signal processor 80. .

The audio signal processing unit 80 and the video signal processing unit 90 process the decoded audio and video signals provided from the MPEG decoder 70 and output them to the speaker 100 and the screen 110, respectively. And the screen 110 are displayed as an audio and an image, respectively.

On the other hand, according to the present invention, if a repeating key signal is input from the key input unit 40 while the playback is performed through the above-described process, the microcomputer 50 determines whether the current playback mode is the normal playback mode or the playback control. In the regeneration control mode, the pickup and actuator unit 10 is moved to the start position of the currently playing entry, and the replaying is repeated for the currently playing entry area. The unit 10 is transferred to the start position of the track currently being played or to the start position of the input section to perform repeat play on the track or section currently being played.

On the other hand, in the case where the repeating key signal of the whole section is input from the key input unit 40, the microcomputer 50 determines whether the current playback mode is the normal playback mode or the playback control mode, as in the case of the one-key repeat key input, In the playback mode, repeat playback is performed for all tracks of the disc being played.

When the current playback mode is the playback control mode, the menu displayed on the menu screen is sequentially and repeatedly played. That is, for example, as shown in FIG. 3, if the menu displayed on the menu screen is' highlight ',' content introduction ', and' playing by time ', first the' highlight is played, and then 'content introduction' is displayed. Playback, and then 'play over time'. At this time, if the menu screen corresponding to the offset value for the playback by time is displayed as '10: 00 ', '20: 00', '30: 00 ', this also plays back sequentially. When the playback of all the menus is completed, the playback is repeated from the first menu again.

When the repetition function release key signal is input from the key input unit 40 during the execution of the repetition function as described above, the microcomputer 50 releases the repetition function, and sequentially executes the reproduction again from the position at which the repetition function is released.

2 is a detailed flowchart of a method of executing a repeating function of a video compact disc player according to a preferred embodiment of the present invention.

In step S10, when the disc is loaded, in step S12, the TOC (table of contents) data recorded in the lead-in area is read and stored, and the VCD file data recorded in track 1 is read and stored. Thereafter, in step S14, a key input is awaited.

When the playback key signal is input in step S16, playback is performed in step S18, and the flow proceeds to step S20.

On the other hand, in step S20, it is determined whether a one-section repetition key signal for a predetermined section or a predetermined track is input. If in step S20, a one-section repetition key signal is input, the process proceeds to step S22; Proceed to S24.

When the process proceeds from step S20 to step S22, in step S22, it is determined whether the current playback mode is the normal playback mode or the playback control mode. In this case, if the normal playback mode, the process proceeds to step S28. Proceed to S26. At this time, if the process proceeds from the step S22 to the step S28, the step S28 repeats the playback of the currently playing track or section, and if the process proceeds to the step S26, the entry area currently being played in the step S26. Play repeatedly.

On the other hand, if the process proceeds from step S20 to step S24, it is determined in step S24 whether the inter-wide repetition key signal is input. At this time, if the inter-repeat repetition key signal is not input, the process returns to step S20 and the inter-repeat repeat key. If a signal is input, the process proceeds to step S30 to determine whether the current playback mode is a normal playback mode or a playback control mode. Further, in step S30, if the current playback mode is the normal playback mode, the process proceeds to step S32, and if the playback mode is the playback control mode, step S34.

When the process proceeds from the step S30 to the step S32, in step S32, all tracks of the disc currently being played are repeatedly played. If the flow proceeds to step S34, the displayed menus are sequentially repeated in the order displayed on the menu screen. For example, playback is repeated in the order shown in FIG.

Thereafter, in step S36, it is determined whether the repetition function release key signal is input. If the repeat function release key signal is input in step S36, the flow advances to step S38, and in step S38, the repeat function is released. Playback is performed sequentially from the position where the repeat function is released.

As described above, the present invention has an effect of efficiently executing the repeat function regardless of the version of the video compact disc in executing the repeat function in the video compact disc player.
