How to Display Disc Information of an Optical Disc Player

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of displaying disc information of an optical disc player, and more particularly, to a user, a plurality of disc information mounted in a tray roulette in an optical disc player having an optical disc changer. Disc information display method of the optical disc player that can be displayed by the information set by the.

Computer and communication technologies are developing remarkably toward the 21st century information society. Accordingly, the amount of information such as text information, voice information, image information, and the like is increasing at an enormous speed, and there has been a demand for development of a storage medium capable of effectively storing the information and a reproduction device capable of reading information stored in the storage medium.

In response to the demands of the times, one of the developed storage media is an optical disk, which is a storage medium capable of storing and reading information using light such as a laser. A mass storage medium that can store data in units of gigabytes (GB). Such an optical disk has a larger storage capacity than a conventional video storage medium (eg, Video Tape) and a good signal / noise ratio (S / N ratio), thereby providing high image / high sound quality. It is possible to obtain a random random access function (Random Access) function that can be played at any location, and its popularity is greatly increasing, and is replacing the existing storage media.

Such a storage medium, that is, a device capable of irradiating light such as a laser to an optical disc and reading data on video, audio, text information, etc. contained in the optical disc, is called an optical disc player. Examples of compact disk players (CDP), laser disk players (LDP) and compact disk graphic players (CDGP), video compact disk players (VCDP) ) And the like.

On the other hand, such an optical disc has a limited storage capacity. Therefore, such as a feature film, the amount of data is so large that the entire data cannot be stored in one disc, but divided into several discs. There is a limit on the number of songs that can be supported by a single optical disc, and an optical disc changer was developed to solve such a problem. At this time, the optical disc changer is mounted on the optical disc player, mounts a plurality of discs in the tray roulette, and continuously reproduces video, audio or text data recorded on each of the mounted plurality of discs.

On the other hand, when one disc is mounted in the optical disc player, it is relatively easy to grasp the contents of the disc. However, when the optical disc changer is mounted, it is possible to distinguish the trays to be changed and the type of disc mounted in each tray. In an optical disc player equipped with an optical disc changer, the TOC (Table of Content) information is read from the read-in area of the optical disc mounted in the tray roulette, and is mounted on each disc tray with reference to the TOC information. The information on the disk is provided to the user on an OSD (On Screen Display) screen. The TOC information includes the name of the disc, the start / end position of each track section of the disc, the start / end position of the entire track of the disc, and the like.

However, since the disc information is displayed based on the TOC information provided by the conventional optical disc player, there is a problem that the information is always output as information and the user's utilization of the displayed disc information is lowered. For example, if the name of a disc containing foreign currency is indicated in the original language (for example, English, French, etc.), it is difficult for a person who does not know the original language to understand the name of the disk.

Therefore, if it is possible to change and set the existing disk information so that the user can recognize it, it will be very easy to understand and use the disk information.

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned point, and for a plurality of discs mounted in an optical disc player having an optical disc changer, the disc information which has been previously changed by the user is utilized. It is an object of the present invention to provide a disc information display method of an optical disc player that can easily recognize and utilize information of a user by constructing a disc information table using disc information based on TOC.

In order to achieve the above object, in the present invention, in the method for displaying information about each of the plurality of disks on a disk information screen in an optical disk player capable of mounting a plurality of disks, the disk information screen is the optical disk. A screen for a disc information table that is temporarily configured only while the player is turned on, wherein a single axis corresponding to each of the plurality of discs, a second axis including a plurality of information fields corresponding to each of the discs, and a specific field are selected. The disk information display method comprising: a first step of reading and storing TOC information including a plurality of information about the disk; A second step of retrieving a disc unique number from the TOC information; A third step of retrieving whether disc information preset by a user is stored corresponding to the disc unique number; A fourth step of updating the disk information table based on the stored disk information if the disk information is already stored, and updating the disk information table based on the read TOC information if the disk information is not stored previously; A fifth step of repeating the first to fourth steps for each of the plurality of disks; A sixth step of displaying the disc information table on the disc information screen when a user request is made; Updating the disk information table according to the changed information when the user changes to predetermined information in the disk information screen, and stores disk information corresponding to the unique number of the optical disk corresponding to the updated information field. 7 steps; And an eighth step of updating the displayed disk information screen corresponding to the updated information table.

The disk information table is configured into a disk information screen by the control of the system control block 200, and the data for the configured disk information screen is provided to the image display block 600.

The system control block 300 controls the overall hardware, including the optical disc player, based on the key signal provided from the user operation block 500 or the signals provided by each component member of the optical disc player 200, in particular, the tray. TOC information sequentially read from the lead-in area of each of the optical discs mounted in the roulette 400 is received from the optical disc player 200 and stored in the data storage block 400.

In addition, the system control block 300 retrieves the disc unique number of each disc from each of the stored TOC information, and previously stored disc information corresponding to the retrieved disc unique number is stored in the data storage block 400. Search the magazine. At this time, the pre-stored disc information includes various types of information of the disc changed by the user, for example, the name of the disc, the type of disc, the number of tracks included in the disc, the start / end position for each track section of the disc, Start / end locations, etc.

The system control block 300 constructs a disc information table based on the disc information pre-stored in the data storage block 400 or the TOC information provided from the optical disc player 200, and the disc information is stored from the user operation block 500. When a key signal for requesting a screen is applied, the optical disk player 200 is controlled to display the disk information screen based on the configured disk information table. In this case, the disc information table is a screen for the disc information table that is temporarily configured only while the power is turned on in the optical disc player 400. As shown in FIG. 3, each of a plurality of discs (for example, three) is used. It consists of one axis (e.g., horizontal axis) corresponding to, another axis (e.g., vertical axis) consisting of a plurality of information fields corresponding to each disc, and a cursor for selecting a specific field.

In the data storage block 400, the disk information previously changed by the user is pre-stored corresponding to the disk unique number of each disk, and a plurality of disks mounted in the tray roulette 400 by recording control of the system control block 300 are stored. TOC information for each of the disks is stored.

The user storage block 500 is a key panel mounted on a remote controller or an optical disc player 200, and has a plurality of function keys including an information key for displaying a disc information screen and a change key for changing disc information. And generate a key signal corresponding to a user's key operation, and provide the generated key signal to the system control block 300.

The image display block 600 includes a display means such as a monitor, and processes and displays data on the disk information screen provided from the optical disc player 200 to the user.

The process of implementing the disc information display method of the optical disc player according to the present invention by the cooperative operation of each member performing the above function will be described in detail as follows.

First, when a plurality of disks are mounted in the tray roulette 100, power is turned on in the optical disk player 200 or a predetermined disk is inserted in the tray roulette 100 in a state where the power is turned on in the optical disk player 200. When loaded, the optical disc player 200 loads any one of a plurality of discs mounted in the tray roulette 100 in accordance with a predetermined order, and reads TOC information from the lead-in area of the loaded disc. Then, if the read TOC information is provided to the system control block 200, the system control block 200 stores the TOC information provided from the optical disc player 200 in a predetermined section in the data storage block 400 (S 10).

Then, the system control block 200 retrieves the disc unique number (i.e., the unique number of the currently loaded disc) from the TOC information (S20), and the disc information corresponding to the retrieved unique number is stored in the disc storage block ( Search if it is stored in 400). That is, it is searched whether there is disk information corresponding to the disk unique number searched in step S20 described above among the disk information previously changed by the user (S30). At this time, in another embodiment of the present invention, the TOC information, which has been previously configured as the disc information table, may also be stored in the disc storage block 400 together with the disc unique number of the disc.

As a result of the search of step S30, when there is disk information corresponding to the disk unique number among the previously stored disk information in the disk storage block 400, the system control block 200 generates a disk information table based on the found disk information. Update That is, the disk information table includes one axis (for example, a horizontal axis) composed of disk fields corresponding to the number of trays provided in the tray roulette 100 and a plurality of information fields for classifying information corresponding to each disk. The retrieved disc information is inserted in the area (field) to update the disc information table (S40).

On the other hand, if there is no disc information corresponding to the disc unique number among the disc information previously stored in the disc storage block 400 as a result of the search in step S30, the system control block 200 generates a disc information table based on the TOC information. Update That is, as in step S40 described above, the disc information table is updated by inserting each piece of information based on the TOC information in the corresponding area (field) (S50).

The system control block 200 then determines whether the next disk remains. That is, in the present invention, the above-described steps S 10 to S 50 are repeated by the number of trays provided in the tray roulette 100. For example, whether the number of times of the above-described repetition steps matches the number of tray roulettes is determined. For example, it is determined whether the next disk to repeat the above steps S 10 to S 50 remains.

As a result of the determination in step S 60, if the next disk remains, the system control block 300 controls the entire system to repeat the above steps S 10 to S 50. That is, the optical disk is controlled to load the disk mounted in the next tray by rotating the tray roulette, and the overall system is controlled to repeat the above steps S 10 to S 50 (S 70).

As a result of the determination in step S60, if the next disk is not left, that is, after configuring the disk information for all the disks mounted in the tray roulette 100 by repeating the above steps S10 to S70, the system control block 200 waits for key signal input from the user manipulation block 500. At this time, in another embodiment of the present invention, it may be configured to perform a predetermined operation (for example, screen adjustment, playback, etc.) (S80).

In the above-described step S80, when the information key signal is applied from the user operation block 500 (S90), the system control block 300 displays information on the disk information table configured through the above-described steps S10 to S70. On the other hand, the optical disc player 200 is controlled to be configured as a disc information screen based on the provided disc information table.

Under the control of the system control block 300, the optical disc player 200 configures the information on the disc information table provided from the system control block 300 into a disc information screen, and displays the data on the configured disc information screen. It is provided to the display block 600. In this case, the above-described disk information screen may be configured by an OSD (on screen display) processing unit (not shown) or graphic processing unit (not shown) provided in the optical disc player 200. will be.

The image display block 600 processes data on the disk information screen provided from the optical disk player 200 to display the disk information screen to the user through a monitor (not shown).

If the change key signal is provided from the user operation block 500 while the disc information screen is displayed by the step S 100 described above (S110), the system control block 200 switches to the information change mode to change the information change means ( For example, a character selection screen displayed in a predetermined section of the disk information screen) is provided to the user, and then a wait for an operation key signal for changing the user's information. At this time, in another embodiment of the present invention may be configured to change the information by the user's key operation through a function key (for example, a character key or a numeric key) provided in the user operation block 500 ( S 120).

Thereafter, the system control block 300 stores information stored in predetermined fields in the disc information table by letters or numbers corresponding to key signals (ie, key signals applied for changing information) applied through the user manipulation block 500. Update the. Then, the unique number of the disc corresponding to the updated information is detected, and the disc information previously stored in the data storage block 400 is updated corresponding to the detected disc unique number (S 130). At this time, if there is no previously stored disk information in the data storage block 400, the various disk information configured corresponding to the unique number based on the TOC information is newly stored in the data storage block 400.

As described above, according to the present invention, the disc information provided by the TOC information can be easily changed by a real user so as to be recognized by the actual user, and displayed on the disc information screen displaying the entire disc information using the previously changed disc information. Thus, there is an effect of facilitating identification of each of the plurality of discs mounted in the tray roulette.
