The present invention relates to an automatic image selection / display method of a karaoke system and a device for automatically selecting and displaying a background image through a computer.

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.

In order to solve these problems, the present applicant has solved the problem that a wallpaper suitable for the lyrics of a song, which is the biggest disadvantage of the existing karaoke system, is not displayed, and the karaoke system can automatically select and display a background image through a computer. The automatic image selection / display method and apparatus thereof have been filed in Korean Patent Application No. 26790 dated July 3, 1999. The automatic image selection / display method of the karaoke system creates and stores a song-image index table consisting of song numbers and image numbers, which classify and assign specific background images according to the subject of selectable songs, and store each background image. The image number is stored in the image database storage means together with the image number, and the image number assigned to the selected song number input from each karaoke half cycle is retrieved from the song-image index table, and the background image corresponding to the image number is automatically selected. And display the background image on the TV monitor of the karaoke half-period by searching the image database storage means by the display unit. In one example of the device embodying this, the video number assigned to the selected song number input from each karaoke half cycle is queried from the song-image index table, and the background database corresponding to the video number is retrieved from the video database storage means. The automatic image selection / display unit for displaying the background image on the TV monitor of the karaoke half-cycle, and the multi-I / O communication board having a plurality of ports for receiving data transmitted from each of the karaoke half-cycle without error without error Front-end processor with a high-speed communication board for transmitting to the computer, and receives the data from the front-end processor to look up the video number from the song-image index table, search the video database storage means, the background image of the video number In real time with the address of the karaoke half cycle A video server having a high speed communication board for transmitting and a video distribution computer for transmitting a video signal to the TV monitor of a karaoke half-cycle at the corresponding address, respectively, Serial communication controller for transmitting data such as song name, start, reservation, cancellation, half cycle address, etc. selected by the customer through communication cable such as RS232C or RS422 for each karaoke half cycle, and the serial communication controller Send / receive software ROM that stores the send / receive S / W for real-time transmission without data loss through communication cable and error to detect the occurrence of error when data is transmitted such as song name, start, reservation, cancellation An interrupt controller for interrupt processing to receive and retransmit the signal It is also to be configured.

However, the automatic image selection / display method of the karaoke system and the apparatus according to the above-described configuration must change the configuration of the karaoke half cycle, and furthermore, the front end processor must be changed, and an expensive image distribution computer is required.

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 an embodiment of the present invention.

According to the present invention in Figs. 1 and 2, a personal computer (PC1 ... PC32) is added to each karaoke while basically using the existing karaoke half-cycle (A1 ... A32) without modification as compared with the conventional invention of the applicant. In addition, it is configured to include only the video server 30 without employing a front-end processor and an image distribution computer.

The personal computer PC1 to PC32 stores data such as song numbers, start, reservation, and cancel commands inputted by the customer through input units such as the remote controller 1 to buttons to the karaoke half cycle (A1 ... A32). When the input data is inputted, the input signal is inputted through a remote control driver and a remote control receiver 10 or through an input of a personal computer PC1 to PC32 connected in common with a button of a karaoke half cycle A1 to A32. It is configured to be input to the PC1 ... PC32, and the LAN card 20 sends a personal computer (PC1 ... PC32) to transmit data of the input half-cycle address (Room No.), song number, command, etc. to the video server 30. ), TCP / IP communication software is stored, and is connected to the video server 30 through a LAN cable.

The personal computer PC1 to PC32 is configured to include image receiving software and a D / A converter to receive a background image from the video server 30 and display it on the TV monitor M1 to M32. At this time, it is preferable that the background image is transmitted as an MPEG standard compressed background image stream. In this case, MPEG decoding software or MPEG decoder is included in order to decode the image image and transmit the image image signal to the TV monitor (M1 ... M32). It is preferred to be configured. Such a personal computer (PC1 ... PC32) is usually sufficient for the Pentium class, and a FastEthernet board can be mounted by the LAN card 20. As shown in FIG. The OS is fine with Win98.

On the other hand, the video server 30 receives data such as a half cycle address (Room No.), a song number, a command, and the like transmitted from the personal computer (PC1 ... PC32), and retrieves the retrieved background image of the personal address of the corresponding address (Room No.). It includes TCP / IP communication software for transmission to a computer (PC1 ... PC32), and includes command interpretation and video software for analyzing data such as its half-cycle address (Room No.), song number, command, and the like. And a song-image index table (T1, T2) consisting of a song number and a video number, each classifying and assigning a specific background image according to the theme of the song selectable in the storage means. In addition, the video server 30 includes a retrieval software to control the image database storage means 40 for storing each background image with the image number. The video server 30 having such a configuration 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. Preferably, the image compression standard is MPEG.

In addition, the image database storing means 40 is preferably stored as a compressed background image stream of the MPEG standard background image, the image database storing means 40, about 5 minutes per background image of a subject For about 50 to 100 topics, about 250 to 500 minutes of hard disk is required, and one hour of MPEG video requires about 500MB, so 2GB to 4GB hard disk is required. 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.

In addition, the video server 30 stores the video signal input when the video signal of the background image is input to the image database storage means 40 as a compressed background image stream to enable the DB function of the background image by the user. It is preferably configured to include an image production software and an MPEG encoder.

The automatic image selection / display apparatus of the karaoke system having the above-described configuration will be described below with reference to FIGS. 1 to 7.

First, in the production of a background image, various music videos are used as a music-video index table (T1) as shown in FIG. 4 in order to reproduce a music video on a VCR and to convert the played video into an MPEG video file. 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.

When the classification is made in this manner, the songs are classified by the corresponding subjects, thereby creating a subject image index table T2 as the song-image index table T2 as shown in FIG. That is, in FIG. 5, 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 the song number and command using the remote controller 1 or the semi-period button using the song-image index tables T1 and T2 and the image database storing means 40 which can be produced as described above, the input signal is inputted. Input via the remote control driver and the remote control receiver 10 by the personal computer PC1 to PC32 or via the input unit of the personal computer PC1 to PC32 commonly connected to the buttons of the karaoke half cycle A1 to A32. A data string consisting of each address (Room No.), song number, and command of the karaoke half cycle (A1 ... A32) through the / IP communication software, the LAN card 20, and the LAN cable, and transmits it to the video server 30 ( 3a).

When data such as a half cycle address (Room No.), a song number, a command, and the like are transmitted, the video server 30 receives an ACK signal when received without error and a NAK signal when an error occurs (A1 ... A32). Send to. At this time, the personal computer PC1 to PC32 retransmits a NAK signal by the reception software of the TCP / IP communication software. The communication protocol is performed according to the protocol of TCP / IP communication software.

The data string is transmitted to the video server 30 via TCP / IP transmission / reception software without error, and the video server 30 immediately interprets the command from the received data string by the command interpretation and image software, and the song number The video number corresponding to the query is retrieved from the song-video index tables T1 and T2, and the corresponding video number is retrieved from the video database storage means 40.

Then, if the received command is started, the video server 30 first updates the flag of the room table T3 by the image software, and judges the presence or absence of the waiting queue, as shown in Fig. 3B. If there is a data stream, the reserved data stream is first transmitted to the personal computer (PC1 to PC32) in order, and the retrieved data stream is queued in the waiting queue. On the other hand, if there is no waiting data stream, the TV monitor (M1 ... M32) of the address (Room No.) of the karaoke half-cycle (A1 ... A32) just found is in use or checked by the room table (T3). Is transmitted to the personal computer (PC1 ... PC32) together with the corresponding half-cycle address (Room No.) via the image transmission software. 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.

Also, if the received command is a reservation, the retrieved data stream is queued in the wait queue Q. If the received command is canceled, the transmission of the video stream is stopped.

On the other hand, the video server 30 unconditionally transmits the retrieved video stream to the personal computer (PC1 ... PC32) together with the corresponding half-cycle address (Room No.) through the image transmission software, respectively, from the personal computer (PC1 ... PC32). It may be configured to create a room table T3 and waiting queue Q for the TV monitor M1 M32 and display the video stream transmitted to the TV monitor M1 M32 through the interpretation of the command similarly to the above. have.

The video stream transmitted as described above causes the personal computer (PC1 ... PC32) to display the video signal converted into an analog signal via the MPEG decoder on the TV monitor (M1 ... M32) as shown in Fig. 3A.

In this way, in the TV monitor M1 to M32, 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 are real-time. By using the user can select and display a specific background image that is appropriately classified through the waiting queue (Q) and the room table (T3) according to the input song number and command.

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. This may be configured to be stopped, or control may be made in the front end processor 20 to impose restrictions on minors, in which case, a song-image index table for minors may be separately constructed and operated.

According to the configuration and operation of the automatic image selection / display method of the karaoke system and the apparatus according to the embodiment of the present invention described above, by installing a personal computer (PC1 ... PC32) in each room, the lyrics of the song by a simpler method and device There are effects such as the automatic selection of the appropriate wallpaper for the display and the display.
