How to Introduce Storage Locations of Optical Disc Players

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disc player, and more particularly, to an optical disc player capable of introducing contents of storage places by sequentially playing a plurality of storage places stored during playback for a predetermined time. It is about how to introduce a place.

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 has a built-in memory function that stores the data at a desired predetermined position during playback, and subsequently allows playback to be performed at the stored position.

By the way, such a memory function can grasp the contents by playing from the position when there is only one memorized place, but it is difficult to grasp the contents recorded in the memory place in a short time when a plurality of places are stored. . That is, in order to grasp the contents of the plurality of storage places, it was inconvenient to check the contents one by one while sequentially executing the reproduction.

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 reproduce contents of storage locations in a short time by sequentially reproducing a plurality of storage locations for a predetermined time. To provide an introduction to the storage space of an optical disc player.

According to a preferred embodiment of the present invention for achieving the above object, in the method of introducing a storage location of an optical disc player for recognizing the contents by sequentially reproducing the predetermined number of storage locations for a predetermined time, ) Loads a predetermined disc, reads and stores TOC (table of contents) data indicating content information on data recorded on the disc recorded in the lead-in area of the disc, and enters a playback key signal.

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 an optical disc player for practicing the present invention.

As shown in FIG. 1, an optical disc player for carrying out the present invention includes a pickup and actuator unit 10, an RF (radio frequency) signal amplification and servo signal processor 20, a motor and 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 performs an optical pickup from a disc loaded in a disc tray (not shown), and outputs the RF signal read out to the RF signal amplification and servo signal processing unit 20 accordingly.

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

The RF signal amplification and servo signal processing unit 20 amplifies the RF signal provided from the pickup and actuator unit 10 and provides a servo control signal according to the signal to the motor and the motor driving unit 30 to provide the focus servo and the tracking servo. To be done.

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.

Meanwhile, according to the present invention, after loading a predetermined disk and reading and storing TOC (table of contents) data including contents information of data recorded on the disk, for example, time information, and the like, from the key input unit 40. When the storage key signal for storing a predetermined position is input from the key input unit 40 while the Jessine key signal is input and the reproduction is executed, the microcomputer 50 is the digital signal processing unit 60 at all positions where the storage key signal is input. The time data of the position to which the storage key signal is input is stored in the internal memory (not shown) with reference to the Q data indicating the time data at the current position provided from &quot; In other words, the time data at all storage locations to which the storage key signal is input while reproducing is stored in the internal memory. When another function key signal is input, the microcomputer 50 generates a control signal to execute a function corresponding to the function key signal.

Thereafter, when a storage place introduction key signal for a stored place is input from the key input unit 40, the microcomputer 50 first determines whether there is data for the storage place stored in the internal memory, and then stores each stored place data if there is any. The storage location data is read and the number of storage locations is read. In this case, when there is no stored storage location data, the microcomputer 50 provides the video signal processor 90 with pre-stored text data indicating that there is no control signal and a storage location, and the video signal processor 90 displays the OSD (on). screen display) and then output to the screen 110 to display that there is no storage place through the screen (110).

On the other hand, if there is a stored memory, first, the content introduction time for the storage location is set, and the content of the storage location is executed by sequentially reproducing the storage location for the set time sequentially by referring to the number and time data of the read storage locations. Introduce

That is, the microcomputer 50 generates a control signal to the motor and the motor driving unit 30 by referring to the time data of the storage place, and drives the motor and the motor driving unit 30 to transfer the pickup unit 10 to the storage place. After that, a playback control signal is generated again to perform playback from that position. When the reproduction for the contents introduction for the set time is completed, the pickup is transferred to the next storage place, and the reproduction is performed for the set time at the position.

On the other hand, the playback time for the content introduction to the storage location may be arbitrarily set by the user through the key input unit 40, or may be preset in advance at the time of production.

As described above, when the playback key signal is input while the content introduction function for the storage location is executed or the playback for content introduction at all the storage locations is completed, the microcomputer 50 releases the storage location introduction function. Normal playback starts again from the position.

2A and 2B are detailed flowcharts of a storage location introduction method in an optical disk player according to a preferred embodiment of the present invention.

If a predetermined disc is loaded in step S10, and a reproduction key signal is input after reading and storing TOC data is completed in step S20, playback is performed in step S30.

If playback is performed in step S30, it is determined whether a storage key signal is input in step S40. At this time, if the storage key signal is input, the flow proceeds to step S50, and if not, the flow proceeds to step S60.

When the storage key signal is input in step S50 and proceeds to step S50, in step S50, the time data at the position where the storage key signal is input is stored and set as the storage location data, and the flow proceeds to step S80. .

On the other hand, if the process proceeds from step S40 to step S60, it is determined whether another function key signal is input in step S60. If another function key signal is not input in step S60, the process returns to step S40. After performing the flow again, if it is input, the flow proceeds to step S70 to perform a function according to the input function key signal, and then ends the flow.

If the process proceeds from step S50 to step S80, in step S80, it is determined whether a storage place introduction key signal for introducing the contents of the storage place set in step S50 is input. In step S90, if the storage-place introduction key signal is inputted, the flow proceeds to step S90, and if not, the flow proceeds to step S40 to perform the flow again.

When the process proceeds from the step S80 to the step S90, it is determined whether there is data for the stored storage location in the step S90. If there is no data for the stored storage location in the step S90, the process proceeds to the step S170. If there is no data on the storage location, and if there is data on the storage location, the flow advances to step S100 to read the storage location data and its number M and proceeds to step S110.

Then, in step S110, the content introduction time at each storage location is set, the first storage location is searched, and playback is performed at that location.

Thereafter, in step S120, it is determined whether the playback time has reached the set introduction time. If the playback time at the storage location reaches the introduction time in step S120, that is, the introduction time is completed, the process proceeds to step S130. Otherwise, the process proceeds to step S150.

First, when the process proceeds from the step S120 to the step S130, in step S130, the number M of the storage places is reduced to '1' (M ← M-1) and the process goes to the step S140 to decrease the number '1'. It is determined whether the number of the stored storage places is '0', that is, whether content introduction at all storage places has been completed. If the number of memory locations reduced by '1' in step S140 is '0', the flow proceeds to step S160; otherwise, the flow returns to step S100 to repeat the flow.

On the other hand, if it proceeds from step S120 to step S150, it is determined whether a playback key signal is input in step S150. At this time, if a playback key signal is not input, the flow returns to step S120 to repeat the flow and input. The process proceeds to step S160.

When the process proceeds from step S140 or step S150 to step S160, in step S160, the content introduction function at the storage location is released, and normal playback is performed from that position.

As described above, the present invention has an advantage of allowing the user to quickly and easily recognize contents at all stored locations by sequentially reproducing for a predetermined time set for a predetermined number of storage locations.
