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

Video Song Half Cycle is a sound source module for music playback, a recording medium storing thousands of song data and lyrics data, a caption generator for displaying lyrics on the monitor, an operation panel and remote control for setting selections and functions. It is configured to play a specific song with the video under the control of the microprocessor.

The song and lyrics data recorded on the recording medium is input to key values corresponding to the respective song data by an operation panel or a remote controller provided with a key which is an external input for performing selection (S1 to S3). When the microprocessor loads the selected song data and loads it into the memory (S4) and plays the data together with the image as accompaniment music through the sound source module (S5), the lyrics data is overlaid on the monitor at the same time. It is controlled by the display process.

At this time, according to the control method of the present invention from the step of controlling the process of reproducing the selected data is a reserved song detection step (S2) for detecting whether there is a reserved music selection, and if there is no reserved music whether there is a selection button selection (S3), a cumulative counting step (S6) of increasing the time count to start counting the input-free time of the selection button when there is no selection button input, and the counted time being a predetermined set time. A time comparison step (S7) of detecting whether it has reached, and a data read which reads the indexed background music data by reading an index file indexed as a list of MIDI files corresponding to background music data from the recording medium when the set time is reached. Step S8 and blocking subtitle reproduction of lyrics data from the MIDI data which is the read background music data (S9). And a volume control step of adjusting the volume from the volume level in use when the background music is played to the set level (S10), and the background music playing step of allowing the MIDI data to be played only through the accompaniment sound through the sound source module (S11). And detecting an external key input while detecting the external key input during playback of the background music, and detecting the external key input so as to interrupt the playback of the background music when the external key input is detected and to interrupt the initial control step (S12). .

On the other hand, in the counting step (S6) of counting the cumulative time that is the input time of the selection key, the increase value of the time count is the microprocessor and the main processor 30 of the panel unit 10 for processing the external key input to be described later. It is calculated by the microprocessor 31 and the timer in the first transmission unit 34 provided between the interconnects.

The timer inside the first transmitter is configured to generate a clock pulse, which is an electrical signal once every 1 m / sec, when power is supplied to the flexible half cycle.

The clock is detected by the microprocessor 31, and a variable area for clock count is allocated to a predetermined portion of the RAM 314. This also starts at "0" at the same time as the power is turned on and is detected every time the clock is detected by the timer. Increase by increments. In this case, the clock count is specified to accumulate and accumulate the clock continuously from the beginning of power-on, and this clock count is variously used for half-cycle control.

The increased cumulative clock number is an important value for knowing how much time has elapsed since the flexible half-cycle power is turned on.

The set time value to be compared with the clock count value is set to a constant time value every time a key input is input, and is a variable set to compare how much time has passed after the key input.

The setting time is a clock counted from the state in which the flexible half-cycle power is turned on, and for example, 5 minutes is added to the cumulative counted current value so that the setting time = current clock count value + (5 minutes × (60 seconds × 1000)). The operation is accomplished.

That is, in the comparison step (S7) of the set time and the elapsed time, the elapsed time, which is a time count value for counting the non-selected music time from when the selection key was last input in the step (S3) of detecting the input, is equal to the set time value. When compared and equalized, processing for playing the background music is started.

The set time value can be set up or down as needed.

On the other hand, looking at the step of reading the background music data file (S8) and the process of playing the accompaniment information, it is processed by reading from the recorded CD-ROM where the background music file is indexed.

The CD-ROM drive has a processor, which is a processor that performs functions within itself, and uses this processor to receive external commands, to process internal commands, to receive data externally, and to configure and transmit various data according to the current drive status. It is also responsible for the mechanical drive of the drive.

The data of the CD-ROM is organized in sector units (2048 bytes), and data is always read in this sector unit.

In the 16th sector of the CD-ROM, information values of all data files existing in the CD-ROM are recorded, and the contents are composed of values indicating the actual sector position value and size of each data file.

Here, the information of the data file to be used in the background music is read to read the actual data position value and size value on the CD-ROM.

To read a file, data is transferred between the CD-ROM drive and the microprocessor. Data read from the drive is stored in RAM.

The microprocessor sends the read command data, the position of the file to be read, and the file size to a CD-ROM drive in a single packet command to read the file.

The drive receiving the command reads the command by the internal processor, recognizes that the command is a READ command, prepares to read by the position value and the file size value, and the drive operates to search the data on the CD-ROM. In case of running, operate the Spindle motor to rotate the CD-ROM to move the pick-up module, which is an optical sensor, to the location corresponding to the file and read the data.

The read data is stored in an internal memory in the size of one sector and output to the outside.

Thus, the flexible half-cycle microprocessor accepts the output and loads it in the order it entered the RAM.

The CD-ROM drive that outputs the data sequentially sends a signal that all data has been output after the last data is output, and enters a standby state to receive the next command, and the microprocessor finishes reading the data.

Referring to the step S9 of blocking lyrics data in the step of outputting the read background music, it is classified as background music and the microprocessor uses the indexed files to read the MIDI data for the background music from the CD-ROM as described above. Read it and load it into RAM.

The background music data loaded in the RAM has both accompaniment notes and information according to the progress of the lyrics.

Basically, the music accompaniment starts to read and play the data of accompaniment, and simultaneously reads the information about the lyrics and processes the data of the lyrics sequentially by processing the accompaniment at the same time. Since it does not need to be displayed, it does not process the lyrics progress information and processes only the accompaniment sound so that it plays a soft background music.

The volume adjusting step (S10) is forcibly adjusted to a level previously set to suit the background music from the current volume level being set and used by the user.

In consideration of the characteristics of the background music, it is necessary to perform quietly and calmly compared to when outputting normal accompaniment sounds.

In order to forcibly reduce the volume level, the microprocessor, the second transmitter 35, and the sound source module 38 of the main controller 30 described below are in charge.

This is done by software. Code values representing the level of accompaniment are provided in the program ROM. The coded level is defined as the limit value of "0 ~ 127" level when converted into numerical value, and the accompaniment sound is processed. When the background music is played, this level is reduced and the result is treated as a chord value of approximately 32 levels by experimental results.

The code value corresponding to the volume level of the background music instructs the sound source module to process the recognition by the micro processor through the second transmitter.

A sound level module has a level value, which is provided with a level value, and adjusts the volume of the sound. When a specific level value is input, the sound source module recognizes that the data is according to the level, and passes the code value to the level processor.

The level processing unit converts the received level numerical value into an electrical signal and distributes it to a circuit, thereby processing and transmitting the sound to be output to the level corresponding to this numerical value. It becomes possible.

An apparatus configuration as an embodiment in which the background music playing method of the present invention is specifically implemented as described above will be described in more detail below.

2 is a block diagram of an image flexible half-cycle capable of playing background music in the inventor's standby state.

The image flexible half-cycle includes a key input unit 14 that detects an external key input by a key input unit or a remote control input unit, and displays various information on a display 11 formed of LEDs by detecting the input of the key input unit to process key input. The MPU 13 which is a central processing unit and the panel part 10 including the interface 12 are comprised.

The panel unit receives a user's control request as a key input and transmits the control request to the main control device, and is used as an operation and display device for showing the state of the main control device to the user.

Also, a CD- consisting of MIDI data having a plurality of accompaniment information recorded thereon, image data providing a moving image, and a background music list index file recording information of specific MIDI data files selected as background music from the MIDI data. The ROM 20 is prepared.

The plurality of MIDI data is composed of MIDI information and subtitle information. The MIDI information is reproduced as a corresponding instrument sound via the sound source module, and the lyrics information is reproduced on the screen by subtitles by the font ROM.

The MIDI file selected as the background music among the MIDI data is configured by storing the list information of the background music data as an index file.

Files corresponding to the background music will be sequentially read out and played when a condition that a predetermined time for playing the background music has elapsed is achieved.

On the other hand, the main controller for processing the information of the CD-ROM as follows.

The main controller 30 stores a program ROM 311 storing a predetermined program necessary for control, a flash ROM 312 for temporarily recording new song information not recorded on a CD-ROM, and a font for subtitle information. A font ROM 313, a ROM 314 for temporarily storing MIDI data and image data read from the flash ROM or CD-ROM, and a video RAM for reconstructing the read ROM data into an image. 37, a converter 32 (DAC) for converting a digital signal of a video RAM into an analog signal, and a moving image on the monitor 60 through an encoder 33 which reproduces the converted analog video signal as an image on a monitor by NTSC method. Is made possible to play.

In addition, the main controller is a sound source module 38 for reproducing accompaniment by processing data from the read MIDI data to the corresponding instrument sound and a converter for converting the digital signal processed through the sound source module into an analog signal ( 39) and the analog accompaniment signal converted via this converter is reproduced to the speaker 50 through a mixer 39a for mixing with an external microphone input signal.

All the control of the main controller is controlled by the microprocessor 31 according to the program of the program ROM 311, and an external input terminal of the microprocessor has a timer for accumulating and outputting the passage of serial data and the time of key input time. A first transmitter 34 and a second transmitter 35 for serially transmitting data of the RAM 314 having read the MIDI data and the image data to the sound source module are provided.

The first transmitter 34 has a timer for serially transmitting data processed by the microprocessor 13 of the panel unit 10 in response to the external key input and detecting a key input time. When no input time without a predetermined key input has elapsed by the timer of the first transmission unit 34, the microprocessor detects that there is no key input for a predetermined time and is classified as background music from the CD-ROM. The read file information is read and the MIDI data of the files is loaded into the RAM 314.

The background music data loaded into the RAM 314 is reproduced as an image and accompaniment sound under the control of the microprocessor 31.

At this time, the accompaniment information in the background music MIDI data is reproduced through the sound source module 38, but the subtitle information is blocked so as not to be overlaid on the image.

After all, the background music is played only with the accompaniment without subtitle information. This is because it is not necessary to play the subtitle information in the background music, and if there is a subtitle, it does not serve the purpose of providing a quiet background music, and thus excludes the playback of the subtitle.

On the other hand, when there is an external key input while playing the background music, the timer output of the first transmitter 34 is cut off, whereby the microprocessor detects data corresponding to the key value input to the first transmitter and is interrupted. The half cycle of returns to its original function, such as finding and playing back MIDI data for the song.

Here, the first and second transmitters 34 and 35 use a DUART / UART chip which is a commercial semiconductor chip that transmits a serial signal as a chip for data transmission.

According to the present invention as described in detail above, a timer built in the first transmission unit accumulates the time when there is no serial transmission data by the first transmission unit for serial transmission of data between the panel unit and the main controller. The microprocessor loads the specified background music data and plays only the accompaniment information and video clips of the background music data, assuming that the user wants to rest for a while when the waiting time reaches the set time (about 5 minutes). The output is to have a new effect.

The setting time for outputting the background music can be set in a variable manner. At the time when the background music is output, the forced volume control from the current use volume to the set volume level is simultaneously performed to make listening to the background music more smooth. It is comfortable.

Therefore, it is a very excellent invention with new effects such as allowing users to talk or listen to music under subtle and sweet tone background music.
