BACKGROUND AN IMAGE AUTOMATIC OUTPUT SYSTEM ON THE KARAOKE}

The present invention relates to a system for automatically outputting a background image in karaoke, and more particularly, to an apparatus for automatically outputting a background image screen suitable for song lyrics to a karaoke half-cycle monitor.

In general, when a user selects a karaoke half-cycle, midi data is output to a speaker through a sound source unit, and lyrics and image data are output to a monitor through a background screen and a subtitle control unit.

Here, as described above, the image data output to the monitor is typically a music video or a picture file in a single layer. Therefore, when the user operates the song half cycle to sing a song, only the same image is repeatedly output to the monitor. There are even many occasional stimulating images that minors see.

In the early karaoke half-cycle system, ie, the half-cycle represented by the laser disc player (LDP), although the song lyrics and the background image were correct, it is a problem to produce a laser disc (LD) for every song. As a kind of operator who selects and plays the song always stays and receives application songs from customers and plays the laser disk player (LDP), there is a problem in the economics, so it appears in the early stage and almost disappears from the current karaoke system. lost.

Therefore, the consumer is easily bored with repeated images, and there is a problem in that the song emotion is not properly expressed by outputting an image that does not match the song selection.

Accordingly, the present invention has been made to solve the above-described problems, the object of which is to store a background image screen suitable for the lyrics of the song in the database, the database according to the data such as half-cycle address and song name provided from the karaoke half-cycle The present invention provides an automatic background image output system for karaoke that searches for and extracts a suitable background image and automatically outputs it to the monitor of the karaoke half-period.

Background of the Invention In order to achieve the above object, the automatic background image output system in karaoke includes a tag tagged with a command signal such as song number, song name reservation number, start and stop buttons, etc. from a karaoke half cycle. A stream client block configured to transmit a command in a format; If there is video information corresponding to a tag-type command provided from a stream client block, the video information is extracted from a database and transmitted to the stream client block in a stream manner to output the video information to the karaoke monitor. It contains the controlling stream server block.

And a database (DataBase: hereinafter abbreviated as DB) 70 and karaoke monitors 90 to 90-n.

Karaoke half-cycle 10 of the karaoke half-cycle (10 to 10-n), if a command signal such as song number, song name reservation number, start and stop button .... etc. from the user who wants to sing a song, the corresponding The nucleus code value converted to the nucleus code (hexadecimal) is transmitted to the stream client block 30.

The stream client block 30 includes a serial port 33, a code generator 35, a service controller 37, a library 39, and a direct X. ) Block 41.

The serial port 33 serially transmits the nucleation code value converted from the karaoke half cycle 10 to the nucleus code (hexadecimal) through the system call interface C to the code generator 35.

The code generator 35 generates a series of code numbers represented by the nucleus code values provided from the serial port 33 as decimal codes and provides them to the service controller 37.

The service controller 37 adjusts a series of tasks related to packet transmission / reception so that the stream client block 30 and the stream server block 50 can communicate through a predetermined tag. The code generator 35 Decimal code provided by the command is made into a packet-type command and transmitted to the library 39 through the system call interface (C). In this case, after receiving the ID from the stream server block 50, the service controller 37 adds the received ID to the above-described packet format command. In addition, the service controller 37 receives a corresponding image file from the stream server block 50, converts the image file into corresponding image information, and transmits the image file to the direct X block 41.

The library 39 is a winsock library, in which an ID provided from the service controller 37 is added, and the stream server block 50 is transmitted through the network A while using the protocol B for instructions made in the packet format. Will be sent repeatedly).

Here, the direct X block 41 receives image information corresponding to the image file from the service controller 37 and transmits the image information to the karaoke monitor 90 of the karaoke monitors 90 to 90-n.

The stream server block 50 includes a library 53, a session controller 55, a kernel driver 57, a disk read scheduler 59, a stream transfer common buffer 61, and a TDI transfer. A thread 63, a network kernel management block 65, and a stream control buffer 67 are provided.

The library 53 is a winsock library. The system call interface receives a tag-type packet command provided while using the protocol B from the stream client block 30 through the network A. (C) transmits to the session controller 55.

The session controller 55 always waits for a connect request from a client, and when a connect request is received from each karaoke half-cycle 10 to 10-n, each session karaoke half-cycle (10) is performed while opening one session and performing initialization. It is a server for issuing IDs to distinguish ˜10-n). The server detects whether a corresponding video file exists according to a packet-type command with a tag provided from the library 53, and the image file is searched for. If present, the kernel driver 57 through the system call interface C, while preparing to transmit the stream (i.e., preparing to transmit information on the service count increase and the size of the image file to the corresponding karaoke half-cycle 10). And network kernel management block 65.

The kernel driver 57 checks the state of the karaoke half cycles (10 to 10-n) and specifies the number information on how many times the current video file corresponds to the karaoke half cycles (10 to 10-n). To ensure that the device driver dispatch calls are sent to the stream control buffer 67 in one order. After the kernel driver 57 is activated by the session controller 55, the kernel driver 57 operates the disc read scheduler 59 to open and stream the video file. In addition, the kernel driver 57 reads management information stored in the stream control buffer 67 and performs an operation in accordance with the situation. At this time, the stream control buffer 67 stores the management information provided from the network kernel management block 65, stores the number information provided from the kernel driver 57, and stores information on the currently opened video file and session. Manage.

The disk read scheduler 59 is responsible for transmitting an image file. The disk read scheduler 59 is a block in which a read thread exists. The disk read scheduler 59 is operated by the kernel driver 57 and then corresponds to the read thread. The service file) is extracted from the DB 70 and transmitted to the stream transfer common buffer 61. At this time, the stream transfer common buffer 61 stores the image file provided from the disc read scheduler 59.

The TDI transmission thread 63 reads an image file stored in the stream transmission common buffer 61 and transmits the image file to the stream client block 30 through the network A while using the protocol B. At this time, after being activated by the session controller 55, the network kernel management block 65 transmits management information for managing whether the current state is a read state or a data request state to the stream control buffer 67 in real time.

A background image automatic output system in karaoke according to an embodiment of the present invention having the above-described configuration will be described in detail with reference to the flowchart of FIG. 2.

First, a user who wants to sing comes to karaoke, enters a room where any karaoke half-cycle 10 of the karaoke half-cycles 10 to 10-n is located, and then operates the karaoke half-cycle 10. Subsequently, when the user operates (powers on) the karaoke half cycle 10, at the same time, the session controller 55 in the stream server block 50 is waiting for a connect request of the karaoke half cycle 10-10-n. In the state, while opening one session according to the requested connection from any karaoke half-cycle 10 and performing the initialization operation, it issues an ID (ID) corresponding to the karaoke half-cycle 10 (step 201).

As described above, when the ID is issued, when the user inputs a command signal such as a song name number, a song name reservation number, a start and stop button ...., etc. using the karaoke half cycle 10, the karaoke half cycle is correspondingly performed. In 10, the nucleation code value converted to the nucleation code (hexadecimal) is transmitted to the serial port 33 in the stream client block 30 (step 202).

The serial port 33 serially transmits the nucleation code value converted from the karaoke half-cycle 10 into the nucleus code (hexadecimal) through the system call interface C to the code generator 35 (step). 203).

The code generator 35 generates a series of code numbers represented by the nucleus code values provided from the serial port 33 as decimal codes and provides them to the service controller 37 (step 204).

The service controller 37 makes the decimal code provided from the code generator 35 into a packet-type command, adds an ID issued to the karaoke half-cycle 10 to the command, and then sends a system call to the added packet-type command. Transfer to library 39 via interface C (step 205).

The library 39 repeatedly transmits the packet-type command provided with the ID provided from the service controller 37 to the library 53 in the stream server block 50 through the network A while using the protocol B. (Step 206).

The library 53 in the stream server block 50 is a tag-packed instruction provided while using the protocol B from the library 39 in the stream client block 30 over the network A. Is transmitted to the session controller 55 via the system call interface C (step 207).

The session controller 55 determines whether a corresponding video file exists according to a tag-type command provided with a tag provided from the library 53 (step 208).

If there is no video file at decision step 208, an error message is sent to stream client block 30 (step 209).

On the other hand, if there is an image file in the determination step 208, while preparing for stream transmission, the kernel driver 57 and the network kernel management block 65 are activated through the system call interface C (step 210). .

Among them, the activated network management block 65 is activated by the session controller 55, and then, in the stream control buffer 67, read state and management information for managing whether the current state is a read state or a data request state. Transmit and store (step 211).

In this state, the kernel driver 57, after being activated by the session controller 55, while grasping the state of the karaoke half-cycle 10, the number information on how many times the current video file corresponds to the karaoke half-cycle (10) In order to ensure fast transmission, device driver dispatch calls are sent to the stream control buffer 67 in one order and stored in order to ensure fast transmission (step 212).

The kernel driver 57 opens the image file, operates the disc read scheduler 59 to transmit the image file in the stream state, and then stores the management information stored in the stream control buffer 67. While reading, the operation is performed in accordance with the situation (step 213).

The disk read scheduler 59 is operated by the kernel driver 57, and then extracts the image file (currently being requested for service) by the read thread from the DB 70 and transmits it to the stream transfer common buffer 61. To store (step 214).

Then, the TDI transfer thread 63 reads the video file stored in the stream transfer common buffer 61, and loads the library 39 in the stream client block 30 through the network A while using the protocol B. To the service controller 37 (step 215).

The service controller 37 receives a corresponding image file from the TDI transmission thread 63 in the stream server block 50, converts the image file into corresponding image information, and transmits the image file to the direct X block 41 (step 216.).

The direct X block 41 receives image information corresponding to the image file from the service controller 37 and transmits the image information to the corresponding karaoke monitor 90. In this case, when the transmitted image information is sprayed on the screen, if the read / write speed is not correct, the stream is sent to the monitor, which causes a problem. That is, when the TDI transfer thread 63 reads the video file stored in the stream transfer shared buffer 61 faster than the rate at which the image file is written to the stream transfer shared buffer 61, the stream transfer shared buffer 61 is used. There is a moment when the stream is stored in the), at this time, in order to store the stream in the buffer to some extent, the karaoke monitor 90 shows a black screen or displays the last frame and stops. To avoid this, the difference in the number of read / write frames in the buffer is calculated at regular intervals (approximately 200 ms), and when appropriate, the problem is solved by appropriate measures. In addition, as well as a signal directly input by the user, the karaoke half-cycle (10) detects a signal that transmits the end of one song, stops the currently playing song and shows a video corresponding to the next song (step 217).

Therefore, after the operator saves the background image screen suitable for the lyrics of the song in the database, the operator searches the database according to the data such as the half-period address and the song name provided from the karaoke half-cycle, extracts the appropriate background image, and then monitors the background of the karaoke half-cycle It can be printed automatically.

Therefore, in the present invention, the operator stores a background image screen suitable for song lyrics in a database, searches a database according to a command such as a half cycle address and a song name provided from a karaoke half cycle, and extracts a background image suitable for the karaoke half cycle. By automatically outputting to the monitor, the user can sing a song for a long time because the song song and the background image screen look at the same screen, and there is an effect that can express the emotion of the song richly without being bored.
