The present invention relates to a method for multiplexing DVD ROM and CD ROM data and a system thereof. More particularly, the present invention relates to a method of displaying data reproduced by one DVD player to a plurality of clients at the same time. The present invention relates to a DVD ROM and a CD ROM data multiplexing transmission method and a system in which a portion is not played but can be displayed at a time difference as needed.

In recent years, small private businesses such as DVD rooms, karaoke rooms, video rooms, and PC rooms are gradually increasing in size due to the introduction of franchise business techniques according to the current trend. In addition, despite being between different industries, there are attempts to integrate and operate these industries.

In particular, in a DVD room, a karaoke room, a video room, or the like, a screen reproduced on the screen is displayed. In the case of a DVD room, if a TV is occupied in one place, subsequent people cannot watch the DVD. However, if a plurality of DVDs are provided, the DVDs can be inserted into another DVD and can be viewed. However, the provision of a plurality of DVD data in this way increases the cost, and the space connected to the server computer and There is a problem in that it takes up a lot of space for storing its own DVD data.

In the case of karaoke, one to three or four programs are broadcast, and an appropriate program is displayed on the screen. In addition, recently, a screen in which the singer of the song name selected by the user is displayed may be displayed. However, if there is no video of the singer who sang the song name, a normal screen is displayed. Also, such data is selectively displayed as a video contained in a server, which is not applicable to a large DVD or video. There was a problem. In addition, the data stored as data in the server as described above may cause a copyright problem, and also because the data stored in the server has a problem that the image quality and sound quality is inferior.

In addition, the server playing the DVD is connected to a plurality of DVD ROM, but since the server recognizes only 23 drives except A to C, there is a problem that the number of rooms is limited.

In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2004-31237 (hereinafter referred to as "cited invention") discloses a method of data-forming DVD data, storing it in a server, and providing the same. The method of citing invention is illegal in relation to copyright, and there is a problem that it is not suitable for the characteristic of changing video data, which is DVD data, and the like. And a problem that the image quality is lower than that of the original DVD data.

The present invention has been proposed to solve the above problems of the prior art, the object of which can be applied to both DVD room, karaoke, etc., one DVD player or CD player to play data to multiple clients at the same time Multiple ROM and CD ROM data transmission method and system for providing DVD data to multiple clients as a source by providing a method of accessing a player or CD player and displaying the data at different time intervals The purpose is to provide.

Another object of the present invention is to form a folder and to recognize it as a virtual drive to be able to set a number of DVD drives regardless of the number of alphabets to configure the DVD ROM and CD ROM data multiplexed to accommodate a corresponding number of rooms It is an object of the present invention to provide a transmission method and a system thereof.

Another object of the present invention can organize a plurality of the set drive using a multi-language, since it can be managed in a cabinet format of the format consisting of the upper folder and sub-folders DVD ROM and CD configured to be organized by DVD genre An object of the present invention is to provide a ROM data multiplexing method and a system thereof.

The present invention for achieving the above object comprises a server configured to use a plurality of DVD devices by changing the drive name as a folder setting using a virtual drive (folder) setting method; A DVD rack composed of a plurality of DVD ROMs or CD ROMs connected to the server; It is composed of a plurality of clients capable of simultaneously accessing any DVD ROM of the DVD tracks via the server and displaying DVD data at the same time.

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

1 is a system configuration diagram illustrating a method of multiplexing a ROM and a CD-ROM data according to an embodiment of the present invention.

Referring to FIG. 1, the server 10 is connected to a DVD rack 20 by USB 1.0, USB 2.0 and / or IEEE 1394 cables. It can be used in connection with other standard communication standard.

The server 10 stores a plurality of MP3 data, song accompaniment data, music video, and the like in a database. However, in particular, DVD data has a copyright problem, and since the DVD data stored as the data has a poor resolution and sound quality, the clients 12, 14, ..., 16 access the DVD directly and receive the data from the DVD. (12, 14, ..., 16), that is, the client (12, 14, ..., 16) is displayed on the display device of the room installed.

The server 10 may accommodate more than a D drive to a Z drive by using a virtual drive (folder) setting method.

The method is as follows. First open the Administrative Tools in Control Panel. Open Computer Management in Administrative Tools. Open the repository and open Disk Management (Local) beneath it. For example, it is assumed that C drive, which refers to a hard drive, and D to Z drives, which generally refer to an optical device drive (ODD), are set. At this time, if a mouse right-clicks the drive of the D drive among the C drive, the D drive to the Z drive, a down menu appears. In the down menu that appears, click Change Drive Letter and Change Path. In the window that appears, select Remove. Again, create a number of folders on the hard drive that users can recognize. Open Disk Management (Local) again. Then, right-click the mouse on the removed D drive and a down menu will appear. Select Drive Letter and Change Path from the down menu. In the window that appears, select Add. Choose Mount to an empty NTFS (Windows XP or Windows 2000) folder. Then, it is mounted in a number of folders already created, for example, a folder A-1. Then, the contents of the D drive are mounted in the form of a folder on the C drive A-1. Likewise, all drives from drive E to drive Z are mounted in folders as A-23 in each folder. Afterwards, drive D to Z again in the same way from A-24 to A-46. If you repeat this process, hundreds of ODDs, such as a DVD drive, will be mounted in a folder on your hard drive. Here, the description has been given to mounting up to 46 drives, but as described, the server can mount as many DVD drives as it can accommodate, which is automatically installed or set by the program automatically. It can be configured to be set to.

In the description, the drive of A-1 to A-46 has been set and described. However, the drive may be configured in a cabinet form to designate a folder for each genre and play a DVD program in the DVD drive corresponding to the folder. That is, a DVD drive that refers to DVD data corresponding to the drama genre should have an A- in front of the drive, and a DVD drive that refers to data corresponding to the action genre should have a B- in front of the drive and corresponding to the melo genre. DVD drives that refer to data have a C- in front of the drive. Other genres can be set separately, and the name of the drive mounted in the folder can be supported in the corresponding multilingual form. For example, if you are using Windows, even if the operating system is set to Korean and English programs as the default language, create a folder with a name in multiple languages, such as Chinese, Japanese, Spanish, etc. Can be mounted. The same is true when using other foreign language windows.

Thus, the server 10 can accommodate a plurality of (26 or more) DVD players. For example, it can accommodate hundreds to thousands of DVD drives, but set the appropriate number of drives according to the capacity of the server.

The DVD rack 20 accommodates tens or hundreds of DVD drives or CD drives, and the plurality of DVD drives housed in the DVD rack are connected to the clients 12, 14, ..., 16 through the server 10. . The plurality of clients 12, 14,..., 16 access the DVD drive among the DVD racks 20 connected to the server 10 to display the corresponding program. At this time, the server 10 provides only the path when the clients 12, 14, ..., 16 access the DVD rack 20, and stores the client information corresponding to the corresponding DVD program information.

2 is a block diagram illustrating an internal configuration of a server according to FIG. 1 of the present invention.

Referring to FIG. 2, the first controller 180 is a DVD program input through the IEEE 1394 input unit 120 or the USB input unit 130 connected to each DVD drive or CD drives in the DVD rack 20. Alternatively, the information of the CD program and the corresponding client (12, 14, ..., 16) information is stored and connected to the corresponding client (12, 14, ..., 16) through the first client control unit 160 give.

When another user accesses the DVD drive, the first controller 180 can access the DVD data displayed on the DVD drive. At this time, since the latest DVD drive is 16x, even if a plurality of clients 12, 14, ..., 16 access at the same time, it can be displayed in real time to a plurality of clients 12, 14, ..., 16, respectively. have.

In this way, a plurality of original data is displayed to the clients 12, 14, ..., 16. Similarly, if another client 12, 14, ..., 16 accesses again, the client 12, 14, ..., 16 is granted access rights. At this time, since the memory capacity of the server is important, the memory capacity is installed to use more than 2G.

The IEEE 1394 input unit 120 may be connected to a DVD or CD in the DVD rack 20 and an IEEE 1394 port having a serial format to receive DVD data at high speed. As is well known, the IEEE 1394 can accommodate a large number of DVD drives and can input and output data at high speed, so that image and audio data can be received at high speed when connected to the DVD rack 20.

The USB input unit 130 may be connected to a DVD in the DVD rack 20 and a USB1.0 or USB2.0 port, which is a serial format, to receive DVD or CD data at high speed. As is well known, USB1.0 is low speed and USB2.0 is high speed, so it is preferable to use USB2.0.

The aforementioned IEEE1394 input unit 120 and the USB input unit 130 are connected to the DVD rack 20 to directly play the corresponding client 12, 14, or DVD data, which is played on the DVD drive, through the first client control unit 160. ..., 16).

The charging unit 150 determines and calculates the charging based on the information inputted by the key input unit 170 and the time of the system timer through the first control unit 180. For example, billing can be selectively specified according to the number and time of users.

The first client controller 160 is connected to the plurality of clients 12, 14,..., 16 through short-range communication such as a LAN through a LAN and a hub, and the clients 12, 14,..., 16. Receives a request that is input through the) and directly transmits the information according to the DVD rack 20, IEEE1394 input unit 120 and the USB input unit 130. In this case, the first client controller 160 is limited to short-range communication such as a LAN, and is not connected through the Internet. This is because a problem such as copyright may occur when the Internet is connected, and there is a problem of inconvenient control.

The key input unit 170 may input information for billing or, if necessary, connect the DVD and the client 12, 14, ..., 16 corresponding to the room and the corresponding drive of the DVD rack 20. You can also command. In other words, a DVD program can be inserted into rack 12, the client can be accommodated in room 10, and the DVD inserted in rack 12 on room 10 can be displayed.

As described above, the first controller 180 connects and stores the client 12, 14, ..., 16 corresponding to the information of the DVD drive according to a preset programming or input of the key input unit 170, The billing unit 150 provides a system time to count the fee to the corresponding client, and performs a command input from the key input unit 170.

3 is a flowchart illustrating a method of multiplexing a DVD-ROM and a CD-ROM data according to an embodiment of the present invention.

Referring to FIG. 3, first, the operator loads a DVD or CD at the request of client clients 12, 14, ..., 16 (step 302).

The DVD or CD data loaded in the DVD or CD drive is played directly by the client (12, 14, ..., 16) in the room where the client (12, 14, ..., 16) enters. (Step 304).

The controller 180 determines whether another client 12, 14, ..., 16 accesses the displayed DVD or CD drive (step 306).

If it is determined in step 306 that the other client 12, 14, ..., 16 is to access the DVD or CD data, the access of the other user is approved under the control of the first control unit 180 and the second The DVD data is transmitted from the beginning to the clients 12, 14,..., 16 so as to be displayed from the beginning of the DVD to the clients 12, 14,. If another user accesses the DVD, he or she will also be able to access the DVD drive, display it from the beginning, and return to step 306 to see if other clients (12, 14, ..., 16) have access. Determine whether or not.

At this time, the number of clients 12, 14, ..., 16 accessing one DVD drive is limited to 30. This is because when the number of clients 12, 14, ..., 16 accessing one client increases, the probability of occurrence of slowdown problems and errors increases, so that approximately 30 clients 12, 14, ... ., 16) only allow access. Any other access is forbidden.

If there is no person accessing the DVD drive determined in step 306, it is determined whether or not the display of the last accessed client 12, 14, ..., 16 has ended (step 310).

If the display of the client 12, 14, ..., 16 which has been determined in step 310 is finally finished, the DVD is ejected (step 312).

If the display of the last approaching client 12, 14, ..., 16 judged in step 310 is not finished, the process returns to step 306 to return to the other clients 12, 14, ..., 16. Determines whether or not) is approaching.

4 is a flowchart illustrating a step of setting a plurality of drives in a DVD ROM and CD ROM data multiplexing method according to an exemplary embodiment of the present invention.

The step of setting a plurality of drives is a process performed in the server and is set before the DVD and CD data transmission method described in FIG. 3.

First, open the management tool of the control panel (step 402).

Open Computer Management in Administrative Tools (step 404).

Open storage in computer management (step 406) and open disk management (local) beneath it (step 408).

Right-clicking a mouse on any one of a plurality of DVD drives set up to 23 causes a down menu to appear (step 410).

When prompted, click on the drive letter and change path (step 412).

In the window that appears, select the Remove command to remove the drive (step 414).

Open a folder on the hard drive that the user can recognize (step 416).

Open Disk Management (Local) again (step 418).

Then, clicking the Today's button of the mouse on the removed DVD drive brings up a down menu (step 420).

Select a drive letter and change path from the down menu (step 422).

In the window that appears, choose Add (step 424). Then a window pops up. Choose to mount on an empty NTFS folder or answer FAT32. Here, NTFS refers to a file format method, which is supported by Windows XP, Windows 2000, Windows NT, etc., and FAT32 is a format method supported by Windows 98, Windows ME, Windows 2000, and Windows XP.

Then, the folder opened in step 416 is selected, and the DVD drive removed in step 414 is mounted in the folder opened in step 416 (step 426).

At this time, if the DVD drive is not erased, only the Z drive can be set. Therefore, it must be set after erasing.

In addition, all the mounted DVD drives are set as shared folders (step 427).

Steps 402 to 427 are repeated for the number of DVD drives installed (step 428). Then, although only 23 can be set in the related art, 23 or more DVD or CD drives can be connected to the server 10 for use. However, since the capacity of the server 10 is limited, it is preferable to connect up to several hundreds.

In the description of FIG. 4, the description has been based on Windows XP. However, a plurality of drives are installed in other operating systems such as Windows 2000, Windows NT, Windows 98, Windows ME, Linux, Unix, OS / 2, or Mac OS. And it can be used to recognize.

Figure 5 is a block diagram showing another embodiment of the server internal configuration of Figure 4 according to the present invention.

Referring to FIG. 5, the DVD device controller 510 is connected to respective DVD drives in the DVD rack 20, and the DVD files displayed in this manner are generated in a buffer form in the database 540. This buffer file looks like a copy of a DVD file, but disappears after it is used. When another user accesses the DVD drive, the buffer file displayed on the DVD drive is created from the beginning and the first user likewise displays the DVD original file. Similarly, when another user accesses again, it creates another buffer file and displays it from the beginning.

The IEEE1394 input unit 120, the USB input unit 130, the charging unit 150, the key input unit 170 and are the same as the description of FIG.

The second client controller 560 receives a request input through the clients 12, 14, ..., 16 and transmits the information accordingly directly from the DVD rack 20 or the buffer file stored in the database 540. Send it.

As described above, the second control unit 580 can accommodate a plurality of DVD drives through the DVD device control unit 510 and the corresponding DVD buffers generated by the DVD device control unit 510 and stored in the database 540. Causes the file to be displayed when requested by the user.

In addition, the second control unit 580 transmits the DVD files input through the IEEE 1394 input unit 120 or the USB input unit 130 through the client control unit 560, so that the corresponding client (12, 14, ..., 16) To be displayed via.

6 is a flowchart illustrating a method of multiplexing DVD ROM data according to another embodiment of the present invention.

Referring to Figure 6, first, the operator loads the DVD at the client's request (step 602).

The loaded DVD file is played through the clients 12, 14, ..., 16 in the room where the client enters (step 604).

The DVD device controller 510 generates a buffer file of the DVD file input through the IEEE 1394 input unit 120 and the USB input unit 130 and stores it in the database 540 (step 606).

The DVD device controller 510 determines whether another user accesses the displayed DVD (step 608).

If it is determined in step 608 that another user accesses the DVD, the clients 12, 14,..., In the room accommodating the customer have buffer files stored in the database 540 under the control of the second control unit 580. 16) to be displayed from the beginning of the DVD (step 610). If another user accesses the DVD, that user also creates a new buffer file to be displayed from the beginning.

If it is determined in step 608 that another user does not have access to the DVD, the process returns to step 612 described later.

The second control unit 580 determines whether or not there are clients 12, 14, ..., 16 in the state of accessing the DVD buffer file (step 612).

If there are no clients 12, 14, ..., 16 accessing the DVD buffer file determined in step 612, the DVD buffer file is deleted from the database 540 of the server 10 (step 614). .

If the DVD buffer file has been deleted from the database 540 of the server 10, the DVD is fetched (step 616).

If it is determined in step 612 that a person accesses the DVD buffer file, the process returns to step 608.

Meanwhile, the method for setting the plurality of drives described with reference to FIG. 4 also applies to the embodiment described with reference to FIG. 6.

The present invention can provide DVD data to a large number of clients as a single source in a DVD room or a karaoke room, and even a DVD containing a popular program can be provided to a plurality of clients. Even if you do not have to buy a lot of DVDs, etc., only one DVD can be played in multiple clients, that is, in a guest room.

In addition, the present invention allows the server to form a DVD drive and recognize it as a virtual drive so that a plurality of DVD drives can be set regardless of the number of alphabets, so that a large number of DVD drivers can be accommodated. Or there is an effect that can be implemented, such as karaoke.

In addition, by creating a buffer, the DVD server and individual clients can share the load over the performance of the DVD rather than the limited user, allowing more users to access a DVD than accessing the DVD directly. It can be effective.
