BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control technique related to playback of a DVD player, and more particularly, to a method for storing playback positions in a DVD player suitable for storing the playback position in case of an interruption during the playback of the DVD player, for example, when the power is turned off or when a disc is replaced. It is about.

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

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 In addition, the signal is reproduced with sound quality, noise is not generated by irregular reproduction and modulation, there is a small distortion, no ghost (ghost), and random access is possible to develop and spread rapidly.

In addition, compact disc players (CDP), laser disc players (LDP) and compact disc graphics players (CDGP), video compact disc players (VCDP), and the like have been developed and widely used in such optical disc players. A digital video disc (DVD) using the moving picture compression technology of 2 and a DVD player for reproducing the same have been developed, which records data of several gigabytes including a moving picture in a 12 cm optical disc such as a current CD. It can be played and also made compatible to play current CDs and VCDs.

On the other hand, in the DVD player, when the stop key is pressed during playback, the playback address at the time when the stop key is input is memorized, and thereafter, the stored playback address is loaded when the playback key is input and the playback is performed from the corresponding point. In other words, when watching a DVD title for a while and then wants to watch it again, instead of playing the title from the beginning, the title is played from the point where it was stopped, thereby increasing the ease of use and playback satisfaction.

However, when a forced interrupt occurs during playback of the DVD player, for example, when the power of the DVD player is turned off or the disc is replaced, the playback memory address is reset. Therefore, when the disc is inserted and the play key is pressed, the playback cannot be performed from the beginning. There is this. In other words, in order to play from the part that was watched, the user has no choice but to search for the title.

As part of the prior art for overcoming this drawback, during playback, the user stops playback at a desired position, saves the time data of the stopped position, and then executes playback again from that position. Memory playback function is built in.

That is, the memory playback function stores a position at which the user stops playback when the user cannot continuously play and watch the disc while the user is playing the predetermined disc. This function allows the playback to be executed continuously.

However, conventionally, when a memory enemy inputs a key signal in order to perform the above-described memory playback, the time data for the position is stored, the playback is stopped, and the state is switched to the key input standby state. There is a disadvantage in that memory regeneration can be executed by storing the memory position data for the point.

In addition, since these functions are preset at the time of product production, there is a problem that the user cannot select the cooking, that is, the user cannot select the memory address or not to select the memory address.

The present invention has been implemented to overcome the above-mentioned limitations of the prior art, and the DVD player has improved playback convenience by storing the playback address in a separate memory according to a user's selection when powering off or replacing a disk during playback of the DVD player. It is an object of the present invention to provide a method of storing a playback position.

According to a preferred embodiment of the present invention for achieving this object, a step of determining whether a forced interrupt is generated in a DVD player which is playing and driving, and determining whether a reproduction address memory key signal is applied when the forced interrupt is generated. And determining whether an input value of a reproduction address memory key applied when the reproduction address memory key signal is equal to a previous value and present playback when the input value of the reproduction address memory key is not equal to a previous value. It provides a method for storing a playback position in a DVD player comprising the step of storing the address in the memory.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a schematic block diagram of a DVD player for carrying out the present invention, wherein the pickup and actuator unit 100, the RF signal amplification and servo signal processing unit 102, the motor and motor driving unit 104, and the key input unit 106 are provided. ), A controller 108, an EEPROM 109, a digital signal processor 110, an MPEG decoder 112, an audio signal processor 114, and a video signal processor 116.

As shown in the drawing, the pickup and actuator unit 100 performs an optical pickup from a disc loaded in a disc tray (not shown), and outputs an RF signal read according to the RF signal amplification and servo signal processing unit 102. .

In addition, the motor and the motor driving unit 104 drive a built-in spindle motor (not shown) to rotate the disk and drive the actuator unit 100 so that the pickup unit 100 performs optical pickup to record the data recorded on the disk. Read and output it as an RF signal. The RF signal amplification and servo signal processing unit 102 amplifies an RF signal provided from the pickup and actuator unit 100 and provides it to the digital signal processing unit 110, and provides a servo control signal according to the signal to a motor and a motor driving unit ( 104) to provide focus servo and tracking servo.

The digital signal processor 110 digitally processes the amplified RF signal provided from the RF signal amplification and servo signal processor 102 and performs error detection and error correction, and then outputs the signal to the MPEG decoder 112.

The MPEG decoder 112 decodes an error corrected digital video signal and an audio signal provided from the digital signal processor 110 based on the MPEG compression format and outputs the decoded video signal to the video signal processor 116 and the audio signal processor 114. .

The audio signal processor 114 and the video signal processor 116 process decoded audio and video signals provided from the MPEG decoder 112 and output them to a speaker and a screen (not shown), respectively. Respectively, the sound is sent out and the video is displayed.

The key input section 106 is to provide a function key signal for executing a predetermined function. The key input section 106 of the DVD player for implementing the present invention is a reproduction address storage key (not shown) in addition to the general function keys. More). The playback address memory key may be implemented in a toggle manner so that the playback address may be stored or reset according to a user's input or repetitive input, which is a common knowledge in the art. If you have it will be easy to know, the detailed description will be omitted.

In addition, the control unit 108 generates a control signal corresponding to the function key signal input from the key input unit 106 to the respective constituent members so that the DVD player executes the function input from the key input unit 106. In addition, the control unit 108 generates a control signal for storing the reproduction address when the tray is opened for forced interruption, for example, when the disc is turned off during disc play, and when the disc is reloaded. It plays a role of judging whether there is regeneration address.

The EEPROM 109 stores the reproduction address at the current reproduction position according to the storage control signal from the control unit 108, or the disc is reloaded and stored from the key input unit 106, more specifically the reproduction address storage key, and reproduced. As a signal is applied, a previously stored reproduction address information is output.

First, Fig. 2 is a flowchart of a playback position storing process in a DVD player according to an aspect of the present invention.

As shown in Fig. 2, in step S200 and step S202, the control unit 108 causes the DVD player to play and drive the DVD player, and a forced interruption during the playback drive, for example, the DVD player is powered off or the disc tray is turned off. Determine if it is open.

As a result of the determination in step S202, if an interrupt has occurred, the control unit 108 proceeds to step S204 to determine whether a reproduction address storage key is applied from the key input unit 106, and if the reproduction address storage key is applied, step S202. Proceed to S206.

In step S206, the control unit 108 determines whether the input value of the reproduction address storage key is the same as the previous value, that is, whether the key value is re-input by the toggle method.

As a result of the determination in step S206, if the current key input value is not the same as the previous value, the controller 108 proceeds to step S208 to store the current playback address in the EEPROM 109. If it is the same as the previous value, the flow advances to step S210 to reset the playback address.

When the disc is inserted again in the state where the reproduction address is stored in the EEPROM 109, the process of FIG. 3 is performed.
