Karaoke device for color television

The present invention relates to a karaoke apparatus that can directly transmit images, voices, and lyrics to color TVs. In particular, it can wirelessly transmit images, voices, lyrics, subtitles, music, and song voices to color TVs, FM radios, and earphones. The present invention relates to a karaoke apparatus for color TV having a special sound effect.

Among the known arts, there is a Taiwan Patent Publication No. 229006, 'Auto Accompaniment Wireless Karaoke Microphone', which is related to the present invention, and FIGS. 8 to 10 respectively illustrate the electric circuit, the liquid crystal display, and the lyrics display caption of the TV. The block diagram is shown as a main component of the standard musical instrument digital interface sound source signal (hereinafter referred to as MIDI) 110, the central processing unit (hereinafter referred to as CPU) 120, the storage device 130, the operation panel 140 and The wireless microphone 150 is configured.

Among them, the MIDI 110 receives an instrument digital interface signal to make a stereoscopic sound by a tone generation method of a wave table, and the CPU 120 receives an input from the outside to perform a control function of each term. The memory device 130 includes two ROMs 131 and 132, one of which is fixed inside the microphone and the other of which is changeable to store compressed digitalized music data. do.

The SRAM 125 is connected between the CPU 120 and the storage device 130, and is used to store the compressed music data extracted by the CPU 120 into the storage device 130.

The operation panel 140 includes an input keyboard 141 and a liquid crystal display 142 for displaying a function, and the input keyboard is used to control the application method and the song broadcasting method of the microphone from the outside, and is connected to the microphone. The receivable liquid crystal display 142 displays various functional states of the microphone under the control of the CPU 120. The wireless microphone 150 receives a voice signal from the outside, mixes it with a music signal generated by the MIDI 110, and modulates the mixed signal and outputs the mixed signal.

Among them, the CPU 120 receives a command input from the outside, takes out the music data from the storage device 130, and sends it to the MIDI 110. Accordingly, the music signal is generated and sent to the wireless microphone 150, and modulated again. At the same time, the MIDI 110 connects the subtitle expansion slot terminal 111 with the CPU 120 to install lyrics and sync data stored in the song from the subtitle expansion slot terminal 111. The display is output to the display subtitle 112 or the liquid crystal subtitle display 113 which is detachably attached. The TV lyrics display subtractor 112 includes a CPU 1121, a font ROM 1122, a RAM 1123, a lyrics display buffer 1124, a graphic data ROM 1125, a dot matrix-image signal change module 1126. And an image signal-UHF or VHF conversion module 1127, an image signal mixing circuit 1128, and an audio mixing circuit 1129, wherein the removable liquid crystal subtitle display 113 includes a CPU 1131, a font ROM ( 1132, a liquid crystal display control circuit 1133, a RAM 1134, and a liquid crystal display 1135. In addition, the signal input port of the TV lyrics display subtitle 112 is an image signal input port 114, two stereo audio signal input ports 115, 116, an image signal output port 117 and a stereo audio signal output port 118, and the image signal is transmitted from the antenna 119 again via the conversion module 1127, and the figure data ROM 1125 has a built-in static shape when the subtitle device does not input an image source. It has a function to output an image.

However, the microphone example of Taiwan Patent Publication No. 229006 has a problem in that it does not meet the following defects and consumer demands due to the actual technology.

(1) From the point of view of 'the main goal to appeal'

As a key feature of the technical features, the TV lyrics display subtitle 'installed' or the liquid crystal subtitle display 113 'installed' is detachable so that a singer can use a microphone in one hand and a liquid crystal in the other hand. The caption indicator 113 or the TV lyrics subtitle blocker 112 must be held, and as shown in the advertisement catalog, the other accompanist surrounds the back of the singer and does not stir simultaneously to the rhythm against the subtitle or indicator. The so-called wireless karaoke chorus is performed by looking at the lyrics of the monochromatic display of the indicator or subtitle, and ultimately, the person who is connected to the outside and starring together stares at the liquid crystal display subtitle. Rely on the rhythm of the song you are memorizing As you learn, you cannot feel real pleasure. In other words, the rhythm of the song is changed according to the rhythm of the song and the rhythm progression of the general TV karaoke accompaniment, and simply changes the lyrics of the song immediately after the lyrics are erased or stagnated. Since it does not stir in different colors in response to the change of, it is extremely simple to lead a beginner and sing, so there is no room for comparison with the existing TV karaoke accompaniment device. It is believed that this product will not be sold well even if it appears on the market.

(2) In view of the co-transmission between FM and TV

In addition to the above, the display or subtitle device needs to be externalized, so that the desired 'wireless' karaoke accompaniment cannot be achieved, and as shown in FIG. 9, the desired 'additional' image is displayed in the image signal mixer circuit 1128. And an 'additional' stereoscopic audio signal mixer circuit 1129, respectively, for outputting an image and audio, and the image signal is directly transmitted from the single antenna 119 via the change module 1127, which is simply an individual unit. Since the image signal or the audio signal can be wirelessly transmitted, the FM modulated signal of the voice and the AM modulated signal of the image cannot be transmitted in a single common antenna without interfering with each other.

(3) In terms of music broadcasting technology

By synthesizing music using waveform tables, it can simply represent the stereoscopic sound of CD sound quality and the level of normal karaoke accompaniment, and it is not possible to adjust the wide range of sound effects in response to different scenes. It just belongs to.

(4) Viewed from an image processing circuit

Since there is no full color image processing circuit therein, it is necessary to circumscribe the image control circuit.

(5) Viewed from the housekeeping circuit

Since there is no lyrics processing circuit, it is necessary to circumscribe the subtitle. That is, the capacitive expansion slot terminal 111 is connected to the detachable liquid crystal subtitle display 113 or the TV lyrics display subtitle 112, and the lyrics are displayed by a 'subject' subtitle display or a subtitle display, and the specification thereof. The subtitler self-decoupling is provided with an 'input input' image signal input port 114, two stereo sound signal input ports 115 and 116, and an 'additional lead wire output' image signal output. Although the port 117 and the stereo audio signal output port 118 are provided to output the video signal and the audio signal, there is no description in the internal structure of the subtitle expander terminal 111, and the lyrics are directly transmitted. The description that it cannot be displayed on the caption machine and that the image signal is also transmitted from the antenna 119 via the conversion module (which does not specifically disclose its internal structure) 1127 is insufficient for the disclosure. Offal becomes, who is thought to be still lacks industrial use value reached the implementation phase.

(6) From the application method of song

It is not easy to apply for the song because you can enter the pairing code of the song.

In view of the above problems, the present invention has a special sound effect capable of wirelessly transmitting image, voice, lyrics, subtitles, music and song sounds from the same antenna for color TV, FM radio and earphones. An object of the present invention is to provide a karaoke apparatus for color TV.

Hereinafter, the present invention will be described in detail based on the embodiments, and the present invention is not limited to these examples.

1 is a block diagram of an electric circuit of a relatively preferred embodiment in a color karaoke apparatus for a color TV of the present invention. As shown in the drawing, a control unit 1, a memory unit 2, a voice synthesis unit 3, and an analog unit ( 4), a color TV transmitting unit 5, an earphone unit 6, an FM wireless transmitting unit 7, and a mixer transmitting unit 8,

Among them, the control unit 1 is formed by connecting the function selector (ie, the control panel) 11 and the LCD liquid crystal display 12 to the CPU 10, and the selector 11 inputs the number of songs. Various functions are controlled, and the CPU 10 reads the selector's data using a CPU of programming number 68EC000, and contributes to controlling each peripheral device by performing calculation and analysis.

The LCD liquid crystal display 12 (or the screen of a color TV) displays the selected song number and strength of various functions, and has the following functions.

(1) The organization number of the application song may be displayed.

(2) It is possible to display the letters of the chorus of 'Female', 'Male' and 'Gender' in the application song.

(3) The font of the 'volume' adjustment can be made to emit light, and the numbers from 1 to 16 can be displayed side by side.

(4) The font of music "speed" adjustment is made to emit light, and the numbers from 1 to 127 can be displayed.

(5) It is possible to automatically delete the book number of the reserved song by flashing the font of the song 'Reservation' and flashing three times side by side.

(6) It is possible to display the high and low numbers side by side by emitting the font of music 'KEY'.

(7) The brackets [] of 'Dance' are displayed so that the number of the dance can be entered.

(8) It is possible to display a random code that gradually changes from rapidity when playing the Bingo Game.

As shown in Fig. 2, the memory unit 2 allows the selector 11 to select the decompressed music data via the CPU 10, and is assembled by the ROM 20 and the RAM 21. The ROM 20 is a so-called music cartridge that can store a large amount of digitalized music data through a compression process and can be arbitrarily expanded as necessary, and is a ROM 20 music cartridge that can be extracted and exchanged. In addition, the RAM 21 makes it possible to temporarily store the decompressed music data.

Among them, each of the main accompaniment music in the ROM 20 includes three parts of basic data, accompaniment music data, and character code, and the accompaniment music data is used to synthesize accompaniment music, and the character code is a lyrics subtitle. At the same time, the basic data is used to produce the rhythm, beat, tone, man's song, woman's song, classification, song name, composition, song, original character, song composition number, and formalities. Records system control programs that can broadcast music, images and lyrics.

Conventional digital data compression techniques mainly use the 0/1 array combining characteristics of digital data, and newly combine digital data 0/1 by arithmetic method to achieve the purpose of data compression, and the technique of compression and decompression On the basis of the calculation method of statistics and mathematics, the conventional calculation method simply adopts GM (Common MIDI) format that conforms to MPEG-1, compresses the MID file (MIDI file), and stores it in the ROM 20. It is considered that the number of digital music data that can be stored is relatively small, and the compression method of the present invention performs the basic compression according to the performance characteristics of the music theory. In other words, the present invention adopts the basic characteristics of the music theory. The compression method of the present invention can be improved by 2 to 4 times compared to the conventional compression technique by simple algorithms after compressing the code. Was, in accordance with the intended even in a ROM having the same capacitance and store the number of digitized music data of two to four times Therefore, the cost of the memory unit for each singing music piece recorded is reduced.

When broadcasting the accompaniment music, the system control program and the decompression processing method are distributed by the CPU 10 to read out the digitalized music data of the ROM 20, decompress it, and restore the original format to store it in the RAM 21. will be.

The voice synthesis unit 3 receives the digitalized music signal to produce stereoscopic sound, and in turn, a voice synthesis processor 30 (SSP: Sound Synthesizer Processor IC), a voice digital signal processor 31 (SDSP: A sound digital signal processor IC) and a digital sound effect RAM IC (DSER) are connected to each other. When receiving an input command from the outside through the CPU 10, the music data is taken out from the memory unit 2 and sent to the voice synthesis processor 30, and then the voice digital signal is temporarily stored or delayed through the digital sound effector 32. By increasing the amount of sound effects synthesized, the synthetic broadcast music reproduces the original auditory sense by returning the original sound as if it were at the performance site.

As shown in Fig. 3, when the present invention adopts the Wave Table voice synthesis processor 30 of the formation number ES5506 and the voice digital signal processor 31 (SDSP IC) of the formation number ES5510, the maximum expansion capacity is It can reach 128 megabits, have 128 kinds of musical instrument sounds and 32 independent tracks to produce most 32 kinds of musical instruments simultaneously. Next, when the user inputs the song number, the CPU 10 and the system control program convert the song number into the address of the ROM 20, read the music data, and output the music data to the voice synthesis processor 30, and the voice synthesis processor ( 30) converts the digitalized music data into the address of the waveform table, reads the instrument sound source waveform from the instrument waveform table ROM, and further outputs to the SDSP IC in a serial manner to further improve the sound effect of the present invention by the SDSP IC. Can be. In other words, the digital data generated by the voice synthesis processor 30 is processed as a sound effect according to a user's request through the SDSP IC, and stored using a digital sound effector (RAM IC) 32. It can then be re-broadcasted, producing different sound effects, such as trill, echo, reverberation, and slinging, and creating a perfect accompaniment for different venue conditions and acoustics.

Therefore, the present invention uses the audio digital signal processor (SDSP IC) 31 to improve the sound quality of the electronic synthesized music, and the electronic synthesized sound effects such as reverberation, trill, slanding, echo, etc. Digital sound effects processing of speech must use time delay, speech analysis, digit filter, discrete free transform and various mathematical operations, especially floating point arithmetic embedded in SDSP IC. While it is possible to achieve various professional sound effects by imitating complex sound waves by rapid operation, the conventional CPU does not include a floating point operator, and thus cannot mimic the professional sound effects of complex sound waves.

In addition, the voice synthesis processor 30 (including the IC corresponding to the MIDI sound source chip) of the speech synthesis unit 3 of the present invention divides the digital code into two types, and one of them is a dance group. Code editing by In other words, the MIDI song editing code is a four-digit code according to the number of parts. The edit code of the dance group is a simple one-number number. When the operation is performed, the function key, the dance key, and the numeric key are sequentially pressed. do. Based on the encoding scheme, the apparatus has a function of a bingo game. The bingo game scans the number code of songs in a dance group, and selects a random code by group. In other words, since the CPU 10 quickly scans the ROM 20 in the memory unit 2 and selects one song according to a delay time set therein, the CPU 10 is set to scan hundreds of songs every second. In the bingo game for 5 seconds, thousands of songs can be scanned. If the ROM 20 in the memory unit 2 of the present invention has 32 megabytes of memory, it can store more than 10,000 songs. 'Bingo game' key, the above 10,000 songs are random numbers, the song stirs to the LCD display 12 or color TV screen, and first stirs quickly after throwing the dice to the roulette board. By becoming gentle, at the end, the song pops out according to the will of man.

In addition, if the speech synthesis processor 30 is code-combined according to the present invention, there are other third numeric codes (passwords), and the songs are classified as suitable for singing by women, suitable for singing by men, or suitable for men and women chorus. Reconnaissance, control, and selection of the CPU 10 causes the LCD 10 to display on the LCD 12 or color TV.

The analog unit 4 converts the digital data into analog via the filter circuit 41 and the preamplifier 42 by an internal digital / analog converter 40 and then from the digital / analog converter 40. The music signal from the microphone 43, the microphone amplifier 44, the digital echo circuit 45, the preamplifier 46 and the like, the sound signal coming from the mixing circuit 47, and then mixed by the mixing amplifier 47, The signal is output through the electronic volume control circuit 48 and the sound source amplifier 49.

The color TV transmission unit 5 is, in turn, a video control microprocessor 50, a color image control logic circuit (ASIC) 51, an image buffer RAM 52, an image / font ROM. 53, an image control program ROM 54 connected to the image control microprocessor 50, an image / audio TV modulator 55 and an oscillator 57 connected to the color image control logic circuit 51; / Audio multiplier 56, image-audio amplification drive transmission circuit 58, the output terminal of the analog unit 4 is connected to the image / audio TV modulator 55, and the image-audio amplification The driving transmission circuit 58 is formed by connecting the high frequency amplifier 581, the driver 582, the transmitter 583, etc. in turn.

In Fig. 4, the color image control logic circuit 51 is an ASIC (Special Standard Integrated Circuit) formed by an RGB digital / analog converter and an image scanning controller, so in particular in combination with a digital color image processing technique, the image / font ROM 53 ) Contains at least 32 static image data that can be exchanged internally, 13,777 Chinese fonts, 26 English fonts, 50 Japanese fonts, 24 Korean fonts, various fonts, user manuals, and all songs. In addition to having a catalog number, images, dynamic lyrics and subtitles are displayed directly in the circuit of the device, so that images, dynamic lyrics and accompaniment music can be synchronized without the need for external aids. I can make it.

The lyrics of the device are displayed on the screen of color TV through the above technical processing, the color tone of the lyrics changes according to the rhythm of the music, and helps the first learner to grasp the rhythm accurately.歌詞), and one pixel on the screen is displayed by a 24-bit memory, and the 24-bit color attribute displays three primary colors of R (red), G (green), and B (blue) by 8 bits. And digital to analog converter, 2 ⁸ = 16,777,216 kinds of color change. Next, when the system CPU 10 reads the ROM 20, it immediately notifies the image control microprocessor 50 of the image control microprocessor 50 as soon as the CPU 10 scouts the control code contained in the ROM 20. The processor 50 changes the color properties of the performance lyrics present in the image buffer RAM 52 and outputs them through scanning of the color image scanning controller, and the user changes color lyrics from the color TV screen to the rhythm of the music. I can see it.

Finally, the image, music voice, user's song, and dynamic lyrics are synchronously wirelessly transmitted from the system assembled by each unit to be displayed on the color TV, followed by wireless karaoke on the color TV. You can do

In addition, the earphone unit 6 (preamp 60, audible frequency amplifier 61, earphone 62 in the order of the output terminal of the analog unit 4), FM wireless transmission unit 7 ( And an FM modulator 70, a multiplier 72, a high frequency amplifier 73, a driver 74, a transmitter 75, and an oscillator 71 connected to the multiplier, in turn), and a mixed wave The mixer 80 of the transmitting unit 8 matches the TV and the FM signal and transmits it through a single antenna 81, and synchronizes images and audio (accompaniment music and user) with respect to color TV, FM radio, and earphones. Voice), dynamic lyrics, music and the sound of the user's song wireless transmission or wired output. That is, the karaoke device is implemented by combining the signal of the image frequency and the audio frequency to transmit to the color TV by wireless radio and to display the screen.

In order to solve the occurrence of mutual interference caused by the color TV and the FM radio synchronously by transmitting a single signal of the audio frequency accompaniment music and the image frequency to a common antenna, and the use of two transmitting antennas An inverted U-shaped mixer 80 is designed, and the FM radio frequency signal and the TV radio frequency signal are combined into one and then transmitted to a single antenna 81.

5 and 6, the present invention is designed in advance wired socket terminal (not shown), the wired socket terminal is connected to the output of the analog unit 4, the earphone unit 6, the microphone amplifier 44 And the audio frequency / image frequency amplifier 551 of the color TV transmission unit 5, respectively. The wired socket terminal connects the 'multi-function wired output socket set 90', and the socket set 90 is a microphone socket 91 external to the external wired microphone and an external stereo earphone type microphone. It is equipped with the 92 and the power socket 93 which is external to a DC power supply, and is fully convenient to use. Similarly, the wired socket terminal has a multi-function wired output plug set 94 inserted therein, and the plug set 94 includes a video plug 95, an audio R plug 96, and a stereo sound. (Audio L) plug 97, which is intended for use in areas susceptible to slight interference or in places that are difficult to transmit (e.g. in hospitals, on airplanes, in high-voltage areas, or other places where electromagnetic interference is easy). When the wired socket set 90 and the wired plug set 94 are connected to the color TV, the same multifunction as in the wireless case can be achieved. Thus, the present invention by the assembly configuration of each member is a karaoke device that can wirelessly transmit or wire the image, voice (accompaniment music and user singing) and dynamic lyrics in three courses.

The principle of operation is to store various musics (including lyrics) counted in 1000 units and store them in a ROM (music cartridge) 20 that can be changed and extracted. When the program number is inputted, the relevant address of the song is output through the execution, operation and analysis of the built-in program of the CPU 10, and at the same time, the program number of the song is displayed on the liquid crystal display 12 so that the ROM 20 receives the song address. When the music data associated with the address is sent to the RAM 21 and stored for a while, the RAM 21 sends the data back to the CPU 10, and the CPU 10 sends a music signal to the voice synthesis processor 30 for various purposes. The instrument signal is synthesized into a total music signal. In order to better listen to the broadcasted music, the speech synthesis unit 3 of the present invention is first constructed by connecting the speech synthesis processor 30, the voice digital signal processor 31, and the voice effector 32 to each other, and a music signal. The voice digital signal processor 31 is analyzed, mixed, and skewed, and then stored in the digital voice effector 32 for a while, and at the same time, the audio digital signal 31 is based on different time intervals. It can be applied to karaoke by reading music signals, creating effects such as low-pitch sound and echo-enhancing, and making you feel as if you are in a grand performance hall. Then, the digital music signal output from the voice synthesis unit 3 is continuously sent to the digital / analog converter 40 of the analog unit 4, converted into an analog signal, and filtered through the filter circuit 41 to preamp. Is sent to 42.

At the same time, the song sound of the person using the present invention is transmitted to the digital echo circuit 45 through the amplification of the microphone amplifier 44 through the reception of the microphone 43, and the strength and weakness of the echo effect are selected and controlled by the selector 11. Therefore, it transfers to the digital echo circuit 45, and completes it via the CPU 10 process. The echoed signal is sent to the preamplifier 46 and then mixed with the music signal from the preamplifier 42 and the mixing amplifier 47, and the mixed signal is adjusted via the electronic volume control circuit 48. do. Similarly, the user controls by using the selector 11 and sends the control signal to the electronic volume control circuit 48 and the sound source amplifier 49 through the processing of the CPU 10 to amplify the signal, and simultaneously transmits the signal to the color TV transmission unit. (5), the earphone unit 6 and the FM wireless unit 7 are transmitted and transmitted from three different routes (to be described in detail later).

After the user inputs the song number, the CPU 10 converts the song number into an address of the ROM 20 in combination with a system control program, reads data from the ROM 20, and notifies the image control microprocessor 50. At the same time, when the image control microprocessor 50 receives the initial signal output from the CPU 10, the image control microprocessor 50 enters the image / font ROM 53, reads image data, and stores the image data in the image buffer RAM 52, 10) sets the A-E accompaniment music related value of the basic data to the voice synthesis unit 3 to make the music data receiveable, and thus the A-E and the lyrics of the basic data in this way. The code transmits this character code to the image control microprocessor 50, the image control microprocessor 50 converts the Chinese internal code into a font ROM address through the image control program ROM 54, Remind After the image control microprocessor 50 reads the font, the image control program ROM 54 converts the image into the address of the image buffer RAM 52 according to the position where the image control program ROM 54 is arranged on the screen of the lyrics. Before storing in the old RAM 52, the position must be read first to display the image data in the buffer port, and the font to be stored is stored in the image buffer RAM 52 after the OR logic operation is performed to display the font. On top of the image, the color image control logic circuit 51 continuously scans the image buffer RAM 52 without interruption, and reads the image data into the color image control logic circuit 51 to perform digital / analog conversion. The R, G, and B image signals are output, and at the same time, the color image control logic circuit 51 generates the horizontal synchronizing signal and the color synchronizing signal, and modulates and transmits them in combination with the color image signal.

The color TV screen (image) or music, lyrics and the number of fixedly stored in the interior is determined by the capacity of the memory, the conversion interval of the color TV screen is determined by the designer, the case of using the present invention When the color TV is turned on, the color static screen appears immediately.

Among them, in the FM wireless transmission unit 7 and the color TV transmission unit 5, mixed signals and image signals of the accompaniment music and the user's song sound are transmitted and output to the following three routes.

(1) The mixed signal of music and song sounds is directly sent to the preamplifier 60 and the audible frequency amplifier 61, amplified, and then transmitted to the earphone 62.

(2) The mixed signal of music and song sounds is made in contact with the FM modulator 70 to produce an FM frequency signal, synthesized with the oscillation signal coming from the oscillator 71 in the double cycle 72, and amplifying the high frequency amplifier 73. Is transmitted from the transmitter 75 by the driving of the driver 74 via the drive, and finally the color TV transmission unit 5 is combined with the output signal by the mixed transmission unit 8 to use the mixer 80. The FM frequency and the image radio frequency are stable and can be transmitted from the single antenna 81 without interfering with each other.

(3) The mixed signal of music and song sound can be contacted with the image / audio TV modulator 55 and modulated simultaneously with the image signal coming from the color image control logic circuit 51, and this signal is subjected to the image / audio multiplier 56 ), The high frequency amplifier 581 is amplified, the driver 582 transmits the signal from the transmitter 583 by the driver, and finally the FM signal is transmitted by the mixer 80. It is synthesized with the signal coming from the transmitter 75 and transmitted by the single antenna 81.

7, the present invention provides the following functions from the keys of the selector 11 and the function keys, and all of the functions described above can be displayed on the screen of the color TV in turn.

There are three functions in the keys that directly control the operation.

(1) Adjustment of song song reservation
