Automatic image selection / display method of karaoke system and its device {METHOD AND APPARATUS OF AUTOMATICALLY SELECTING AND DISPLAYING A BACKGROUND PICTURE FOR A MUSIC ACCOMPANIMENT SYSTEM}

The present invention relates to an automatic image selection / display method of the karaoke system and a device thereof, and more particularly, to solve the problem that a background screen suitable for song lyrics, which is the biggest disadvantage of the existing karaoke system, is not displayed. The present invention relates to an automatic image selection / display method of the karaoke system and a device for automatically selecting and displaying a background image through the same.

In the existing karaoke half cycle, only the lyrics of the song appear on the TV screen, and the lyrics can be processed by color subtitles according to the beat, and the TV screen can be played on a screen connected to an external VCR or LDP (Laser Disk Player) repeatedly. As a result, there is a problem that a background image irrelevant to the song lyrics is displayed, and even an irritating image that is embarrassing to a minor is seen.

And there is a problem that the same image is repeated repeatedly is boring. In the early karaoke system, that is, the karaoke system using the LD method had a perfect song lyrics and a background image, but it was difficult to produce LD for every song, and there was always a kind of DJ who selects and plays LD. It is either a method of accepting an application song and regenerating the LD or exchanging it using an expensive mechanical exchange device.

In order to solve this problem, the background image reservation and playback method disclosed in Korean Patent Application Publication No. 99-035715 (published on May 15, 1999) can be used for music playback and playback of a background image using a MIDI CD. Select and store the playback position of the video signal being played as the background image of the accompaniment, and when the user requests the reservation background image playback mode by the user, the image is played along with the music accompaniment from the previously stored playback position. A first step of allowing the user to sing in accompaniment with the video as a background; Calculating a start position of a list which is being played when a background image reservation key is input; A third step of storing the calculated start position of the playlist; A fourth step of searching for the stored start position on a disc when a reserved background image selection key is input; And a fifth step of playing back video data from the searched playback position.

In addition, a first step of using an optical disc and sequentially detecting video data on the optical disc when a reproduction request is made; A second step of storing the detected image data for a predetermined time required to move a playback position and then starting to read and play the detected video data; And a third step of reading out and reproducing previously detected and stored image data during a search time of the changed-requested reproducing position when the reproducing position is requested.

However, the background video reservation playback method and the video disconnection prevention method still contain the above problems.

Accordingly, the present invention is to solve this problem, and solved the problem that the background screen suitable for song lyrics, which is the biggest disadvantage of the existing karaoke system, is not displayed, and the background image can be automatically selected and displayed through a computer. It is an object of the present invention to provide an automatic image selection / display method and apparatus of the karaoke system.

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

1 is a schematic structural diagram of an embodiment of an automatic image selection / display apparatus of a karaoke system according to the present invention.

The automatic image selection / display device of the karaoke system according to the present invention is augmented the absence of a background screen suitable for the lyrics of a song, which is the biggest disadvantage of the existing karaoke system, and each karaoke half-cycle to automatically select and display a background image through a computer. The automatic image display unit 10 and the image database receive the half cycle address (Room No.) and the name of the song from the background image, and search for a background image suitable for the subject of the song and display the background image on the TV monitor of the karaoke half cycle. It comprises a storage means 40. In addition, the karaoke half cycle (1), as shown in Figure 4, the song name, start, reservation, cancellation, half cycle selected by the customer through a communication cable such as RS232C or RS422 to configure the automatic video karaoke half cycle (A1 ... A32) A serial communication controller 2 for transmitting data such as an address (Room No.) and a transmission / receiving S / W stored in the serial communication controller 2 for transmission in real time without data loss via a communication cable are stored. And an interrupt controller 4 for interrupt processing to receive and retransmit an error generation signal NAK in order to detect the occurrence of an error when data such as a song name, start, reservation, cancellation, etc. of the song is transmitted. And a video karaoke half-cycle (A1 ... A32).

The automatic video display unit 10 includes, as an example, a front end processor 20, a video server 30, and an image distribution computer 50. same.

The front-end processor 20 (FEP (Front-end Processor)) communicates with each karaoke half-period 1, and the half-period address (Room No.), song name, start, cancellation, reservation, etc. transmitted from the half-cycle The data is received in real time and transmitted to the video server 30. The front end processor 20 can be said to be a computer dedicated to communication, and communication with the karaoke half-cycle 1 uses RS232C or RS422 and is connected to the video server 30 via a LAN (Local Area Network). Control up to 32 communication ports. Therefore, it can communicate with 32 karaoke rooms. As shown in Fig. 5, the front end processor 20 is equipped with a 32-port multi-I / O board. That is, it is a 32-port communication board that receives data strings transmitted from the 32 karaoke half cycles 1 without error. It is preferable to use the PCI bus interface in consideration of the speed problem. The Async transmission / reception software transmits the data string received from the karaoke half cycle (1) to the TCP / IP LAN through the TCP / IP transmission / reception software if there is no error. It sends to the server 30, and if there is an error, sends a NAK signal in half cycle requesting retransmission in half cycle. The two transmit / receive software are always driven by programs that reside in memory. PC specifications are usually sufficient for the Pentium class and are equipped with FastEthernet boards. The OS is fine with Win98.

The video server 30 is a kind of image storage computer for storing, managing, and searching a background image, and may use a PC server and an NT OS. The background image is DB by subject, and the music video can also be DB. The image compression standard is MPEG. The MPEG encoder function is built in to create MPEG images. And communication software for transmitting the retrieved background image to the image database storage means 40 in real time is required.

As shown in FIG. 6, the video server 30 transmits and receives the data string received from the front end processor 20 directly to the command interpretation and image retrieval software. The image stream is retrieved from the image DB and the image stream is transmitted to the image transmission software, and the image transmission software transmits the retrieved image to the image distribution computer 50. In addition, an MPEG encoder board may be mounted to form an image DB. Video signals input from analog devices such as VTRs, LDs and camcorders in the MPEG encoder board are compressed and changed into digital MPEG files on a hard disk in real time and stored in the image database storage means 40. The hard disk interface uses Ultra Wide SCSII for speed and scalability.

In addition, the transmission and reception software and the image transmission software operating in the video server 30 are software using the TCP / IP protocol to ensure the reliability of data transmission, and the OS considers the characteristics of the image DB, storage capacity and stability of the NT server. It uses 256MB of memory, 12GB of hard disk, Pentium II or higher for CPU, and is equipped with FastEthernet board.

The image database storage means 40 makes an image about 5 minutes per background image of one subject, and requires a hard disk of about 250 minutes to 500 minutes for 50 to 100 subjects, and an MPEG image is about 1 hour. Since it requires about 500MB, you will need a hard disk of 2GB to 4GB. If you add music video footage here, it will be 800 minutes, or 200 minutes of 4 minutes, which is equivalent to 7GB. Therefore, the total hard disk capacity is expected to be at least 9GB and up to 12GB. In light of the trend that hard disk prices continue to fall relative to capacity, it is economical and there is less cost burden in the future. In addition, it is desirable to construct a music video and a subject image DB separately for efficient image retrieval.

The image distribution computer 50 transmits the background image signal retrieved from the video server to the TV monitor M1 ... M32 having the original karaoke half cycle 1 to display the image. To this end, an MPEG decoding function capable of decoding MPEG as an image compression standard and a communication protocol (TCP / IP) capable of receiving multiple MPEG images (up to 32) from the video server 30 are provided. In addition, since the MPEG image is a digital signal, it is provided with a D / A converter for output to an analog TV monitor (M1 ... M32) and includes up to 32 analog NTSC ports. Here, 32 means the number of possible rooms. For this purpose, if four 8-channel multi-pem decoder boards are installed, 32 multi-eppek video streams are generated, each of which is decoded by the corresponding address (Room No.) and converted into an analog signal, and corresponding karaoke half-cycle Can be transmitted to the TV monitors M1 to M32.

As shown in Fig. 7, the video distribution computer 50 receives an address (Room No.) and a corresponding video stream file from the video server 30 by video receiving software, and transmits it to the video classification software. The image classification software first checks the presence or absence of data strings waiting in the waiting queue Q shown in FIG. 9, and if there is a data string in the waiting queue Q, processes them in order, and if not, the data string just received. The room table (T1) of FIG. 8 is used to check whether the address (Room No.) and the TV monitor (M1 ... M32) of the address (Room No.) are in use, and if available, via the MPEG decoder board. The transmitted background image is displayed by sending the image converted into the analog signal to the TV monitor M1. If the TV monitor (M1 ... M32) of the corresponding address (Room No.) is in use, it waits in the waiting queue (Q), and then processes the data received from the image receiving software, and repeats the above method. do. This can be done by a program called Room Monitor, which always checks the room table T3 and displays "Not Available" if available and "Available" if available. At the same time, it checks the data waiting in the waiting queue (Q) to check whether the TV monitor (M1 ... M32) of the corresponding address (Room No.) is available, and continuously updates the room table (T3) so that the room monitor can refer to it. do. The video distribution computer 50 is equipped with a Pentium II class CPU or more, a 512KB memory, a 6GB hard disk, four 8-channel MPEG decoder boards, and the OS uses Win98.

The automatic image selection / display apparatus of the karaoke system having the above-described configuration will be described below with reference to FIGS. 2A to 3B and 9.

First, in the production of a background image, various music videos are music videos as music-image index tables T1 and T2 as shown in FIG. 3A in order to reproduce a music video on a VCR and to convert the played video into an MPEG video file. Create a table (T1). For example, 1001 is Yoo Seung-jun's "passion", and the video number of this music video is number two. Like this, create a table that maps all music videos and their songs and make them in a DB on the video server.

A song without a music video can analyze the lyrics of the song to identify the key themes and then roughly break it down into 50-100 themes. For example, the subject is as follows.

Love, friendship, farewell, sadness, joy, death, encounter, mother, child, children, army, war, teacher, passing, studying, letters, admission, graduation, memories, booze, exercise, valentine, success, clause, sea, Spring, summer, autumn, winter, snow, mountain, hometown, jealousy, love, money, dream, han river, seoul, promise, apartment, dating, fate, woman, friend, school, child, cartoon, dream, etc.

In this case, the songs are classified by the corresponding subjects, thereby creating a subject image index table T2 as the song-image index tables T1 and T2 as shown in FIG. 3B. That is, in FIG. 3B, the song No. 2011 (not only love) is mapped to the theme 1001 (love), and the song No. 3000 (love) is also mapped to the theme 1001 (love). This table is made into DB in the video server 30.

In the above, the music video and the subject video DB are separately constructed for an efficient video search, but the present invention is not limited thereto, and it is possible to build them as a whole. It is also possible to build a table separately so that it can be used as an image.

In addition, when the image DB is possible in the karaoke system itself, it is convenient to change the table when adding a new song or modifying an existing song number, and the image DB becomes easy even when adding a background image.

When the customer inputs a song number and a command by using a remote controller or a semi-period button using the song-image index table (T1, T2) and the image database storage means 40 that can be produced in this way, the video karaoke half-period (A1 ‥ A32 The data string is interpreted by the transmit / receive software ROM (3) and the data string is generated by the address (Room No.), song number, and command, and sent to the front end processor 20 through the serial communication controller 2 and RS232C or RS422. When the front end processor 20 receives the error without error, an ACK signal is transmitted, and when an error occurs, the NAK signal is sent to the video karaoke half-cycle (A1 ... A32). At this time, the interrupt controller 4 of the video karaoke half periods A1 to A32 is operated to retransmit the NAK signal by the reception software of the transmission / reception software ROM 3. Since the communication protocol is Async, communication follows the general Async protocol.

The front end processor 20 transmits the received data string to the video server 30 via the TCP / IP transmission / reception software to the TCP / IP LAN if there is no error, and the video server 30 immediately transmits the received data string. Immediately interpret the command, query the video number corresponding to the song number, retrieve the video number from the video database storage means 40 and transmits the video stream to the video distribution computer 50 via the image transmission software.

In the image distribution computer 50, the image classification software first determines whether there is a waiting queue, as shown in FIG. 2B, and if there is a data string, first processes it in order, and if not, the address of the data string just received ( The TV monitor (M1 ... M32) of the Room No.) is in use or checked by the room table (T3), and if available, the image converted into an analog signal is sent to the corresponding TV monitor (M1 ... M32) via the MPEG decoder. . If the TV monitors M1 to M32 of the corresponding address (Room No.) are in use, they are registered in the waiting queue Q and waited. Then the received data is processed repeatedly.

In this way, the TV monitor M1 M32 uses the MPEG image data stored in the image database storage means 40 and the song-image index tables T1 and T2 stored in the video server 30 in real time. According to the number and command, it is possible to select and display a specific background image which is appropriately classified and classified through the waiting queue Q and the room table T3.

In addition, it is possible to configure to send emergency messages, congratulatory messages, greeting messages, etc. to each room, and when the cancel command is input, the video being displayed until the restart is displayed, but the video is displayed immediately after cancellation. It may be configured to stop. In addition, in order to restrict the minors, the front end processor 20 may be controlled, and in this case, a song-image index table for the minor may be separately constructed and operated.

According to the configuration and operation of the automatic image selection / display method and apparatus of the karaoke system according to an embodiment of the present invention described above, such that a background screen suitable for song lyrics can be automatically displayed at the start of the selected song, etc. It works.
