    Bad disk processing device and processing method in optical disc player
    The present invention relates to a bad disc processing device and a processing method in an optical disc reproducing apparatus. More particularly, when a VCD is mounted on a disc reproducing unit for reproducing, the disc reproducing time recorded in the first track of the VCD is read out. The present invention relates to a bad disk processing apparatus and a processing method for an optical disc reproducing apparatus capable of reproducing a desired screen by reproducing by setting a reproduction time arbitrarily to 1 second when the read time is less than 1 second.
    In general, an optical disc player such as a VCD or DVD reproduces audio and video signals recorded on a disc according to the MPEG (Moving Pictures Experts Group) protocol, and its use is gradually increasing.
    The disk recorded together with the above-described audio and video signals can not only be easily damaged but also can reproduce the recorded data cleanly using a laser.
    Here, MPEG is a standard defined by a moving picture expert group of ISO (International Standardization Organization), and audio and video signals are compressed according to the MPEG standard described above.
    The compressed audio and video signals are time division multiplexed, and the multiplexed audio and video signals are divided into packets and transmitted.
    In this way, the audio and video signals compressed according to the MPEG standard are not only asynchronous, but the time relationship between the audio and video signals, that is, synchronization does not exist at the time of transmission. The audio signal and the video signal are synchronized so that the picture and sound exactly match.
    In addition, the VCD is divided into three signal areas, that is, a lead-in area, a program area, and a lead-out area. Each signal area is separated from the center of the disc. It has data in the form of a projection called a pit along a track spiraling outward.
    The program area consists of 99 tracks, of which program files necessary for playing a VCD are recorded by the VCD producer, and program data are recorded in the remaining tracks.
    On the other hand, there are two types of VCDs: a VCD version 1.1 and a VCD version 2.0. The difference is that the data recorded on the first track is first recognized when the VCD is mounted on the disc player, and the recognized data is first recognized. On the basis of this, the programs recorded between the second track and the 99th track are sequentially played.
    However, version 2.0 VCD displays the menu screen on the screen of the video display device connected to the optical disc player so that the user can know the program recorded in the program area before playing the program recorded between the 2nd track and the 99th track. This allows the optical disc player and the user to play programs recorded on the VCD in an interactive format.
    1 is a schematic block diagram for explaining the configuration of an optical disc player according to the prior art.
    As shown, the disc reproducing unit 1 reproduces audio and video signals recorded on the VCD.
    When the VCD is mounted in the disc reproducing unit 1, the first control unit 2 recognizes the data of the first track input from the disc reproducing unit 1 and performs a preparation mode for reproducing the VCD. The reproducing operation of the disc reproducing apparatus is controlled in accordance with the key signal inputted by the disc.
    The signal processing unit 3 processes and outputs a digital video signal reproduced by the disc reproducing unit 1 under the control of the first control unit 2.
    The decoding unit 4 restores an image signal input from the signal processing unit 3 and outputs the video and audio signals separately.
    The encoder 5 encodes the video signal output from the decoding 4 into a single video signal, converts the video signal into a composite video signal, and outputs it to an image display device such as a television receiver.
    At this time, the encoder 5 outputs a composite video signal by encoding by NTSC (National Television System Committee), PAL (Phase Alternating by Line) or SECAM (sequentiel couleur a memoire) method according to the method adopted in each country. do.
    The OSD unit 6 outputs a text signal so that the menu screen is displayed on the screen of the image display device according to the control signal of the second controller 2.
    The audio amplifier 7 amplifies the audio signal output from the decoder 4 and outputs the audio signal to a speaker connected to the inside or outside of the monitor.
    Referring to the accompanying drawings, a processing operation for a defective VCD of a conventional optical disc player constructed as described above is as follows.
    FIG. 2 is an operation flowchart for explaining a process for a bad disk of the video optical disk player shown in FIG.
    As shown, first, the first control unit 2 determines whether or not the VCD is mounted in the disc reproducing unit 1 (S21), and if it is determined that the VCD is mounted, the first control unit 2 receives the first input from the disc reproducing unit 1. Whether or not the playback time is zero in one track data is determined (S22). If the playback time is zero as a result of the determination, the playback is performed up to the time specified in the still picture data format (S23).
    As a result of the determination in step S22 of determining whether the playback time is zero, when the playback time is not zero, a variable (hereinafter referred to as "N") for determining the playback time is read from the first track of the VCD. Multiply by 5 sectors to determine the end time as the end time for playback (S24).
    However, the prior art as described above has a problem that it is impossible to reproduce an optical disc in real time when the N value is smaller than 10.
    Accordingly, an object of the present invention is to read the disc playback time recorded in the first track of the VCD when the VCD is mounted on the disc playback unit for playback to solve the above-described problems, the read time is less than 1 second The present invention provides a defective disk processing apparatus and processing method for an optical disk player for reproducing a desired screen by setting a playback time to 1 second arbitrarily.

    In the optical disc reproducing apparatus according to the present invention for achieving the above object, the present invention provides a control signal for recognizing the second control unit when the disc is mounted in the disc reproducing unit and the disc reproducing unit to play the first track. And the disc reproducing section reproduces in response to the control signal and outputs the reproducing time recorded in the first track on the disc to the control section through the signal processing section to determine whether the reproducing time is zero or not. If the playback time is non-zero, it is judged whether N is less than 15, if it is small, replaces N with 15, and multiplies N by 5 sectors. Determine and play back.
    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    3 is a schematic block diagram for explaining the configuration of an optical disc player according to the present invention.
    As shown, the disc reproducing unit 10 reproduces audio and video signals recorded on the VCD.
    When the VCD is mounted on the disc reproducing unit 10, the second control unit 20 determines whether the N value is 15 or less when the reproduction time which is the data recorded on the first track input from the disc reproducing unit 10 is zero. By determining the end time with the result value obtained by multiplying N by 15 arbitrarily and multiplying N by 5 sectors, the playback operation of the optical disc player is controlled.
    The signal processor 30 processes and outputs a digital video signal reproduced by the disc reproducing unit 10 under the control of the second controller 20.
    The decoder 40 restores an image signal input from the signal processor 30 and separates the video signal into a video and audio signal.
    The encoder 50 encodes the video signal output from the decoding 40 into a single video signal, converts the video signal into a composite video signal, and outputs it to an image display device such as a television receiver.
    At this time, the encoding unit 50 encodes the NTSC, PAL or SECAM method according to the method adopted in each country, and outputs the composite video signal.
    The OSD unit 60 outputs a text signal such that a menu screen is displayed on the screen of the image display device according to the control signal of the second controller 20.
    The audio amplifier 70 amplifies the audio signal output from the decoder 40 and outputs the amplified audio signal to a speaker connected to the inside or outside of the monitor.
    The operation of the optical disc player according to the present invention configured as described above will be described in more detail with reference to the accompanying drawings.
    4 is an operation flowchart for explaining a process for a bad disk to play back when a bad VCD is mounted according to the present invention.
    As shown, first, the control unit 20 determines whether or not the VCD is mounted in the disc reproducing unit 10 (S41), and when the result is determined, among the first track data input from the disc reproducing unit 10. It is determined whether or not the reproduction time is zero (S42). If the reproduction time is zero as a result of the determination, the reproduction is reproduced until the time determined in the still picture data format (S43).
    In this case, as a result of the determination of whether the reproduction time is zero (S42), if the reproduction time is not zero, it is determined whether N is less than 15 (S44), and when the determination result N is less than 15, N Is replaced with 15, and the result value obtained by multiplying N by 5 sectors is determined as the end time, and the optical disc reproducing apparatus is controlled to reproduce (S46) for the determined time.
    If N is greater than 15, step S46 is performed to determine N as the end time by multiplying N by 5 sectors.
    Therefore, as described above, according to the present invention, when the playback time is not zero among the data recorded on the first track, N is replaced by 15, and the result value obtained by multiplying N by 5 sectors is determined as the end time. Provides the effect that you can play.
