In addition, the video and audio information transmitted from the control unit 20 using a television broadcast or the Internet as an information source can be recorded on a disc by the DVD drive 15 and the HDD drive 16.

Reference numeral 20 denotes a control unit including a microcomputer, which includes a timer and a memory 20a, and is connected in one direction or bidirectionally in accordance with the circuit units and their functions. In the memory 20a, the identification number data is stored in the number storage area, and information such as characters related to the lyrics of the music is stored in the text storage area. The control unit 20 is connected to the modem 19, and can transmit and receive information to and from the Internet via a telephone line. The control unit 20 controls the operation of karaoke based on a command signal from the remote controller 10, records video and audio signals on a video tape, or reproduces the recorded signals. Music editing is performed by assigning a specific identification number to the video tape or storing character information and the like related to the lyrics in the memory 20a in accordance with the music recorded on the video tape. In addition, after the playback of the music recorded on the video tape is started based on the playback command, the control is performed such that the characters of the lyrics and the like are displayed in synchronization with the video sequentially displayed on the CRT4 screen. .

Next, the editing operation of the karaoke apparatus will be described with reference to the flowchart of FIG. When a user wants to create a karaoke tape, he or she uses a cassette tape (cassette) on which accompaniment of music and background images are recorded in advance. Also prepare a booklet of the song that contains the lyrics of this song. First, when the power key is turned on with the remote control 10, a power-on command is transmitted to the main body. The control unit 20 starts the operation in accordance with the power-on command, and checks whether or not a cassette has been inserted (step S11).

Next, when the user operates the menu key, the control unit 20 sends a display control signal to the OSD circuit 5 in accordance with the menu display command, and causes the CRT 4 to display menu items. When the user selects music editing from the menu, an editing command signal is input to the control unit 20 (step S12). The control unit 20 starts the operation of the reproduction system including the recording / reproduction processing unit 6 based on the edit command (step S13). Then, as the video tape runs, the CTL signal of the CTL area is read by the CTL head 9 and transmitted to the control unit 20 side. When the control unit 20 receives the CTL signal, the control unit 20 compares the CTL signal with time data set in the memory 20a in advance to determine whether the signal is a head detection signal (step S14). The time data corresponds to the length of the transparent portion provided for detecting the beginning of the video tape.

Here, if the CTL signal indicates the head detection signal, the control unit 20 operates the counter to generate a cassette number serving as a unique identification number. Then, the data of the cassette number is transmitted to the recording / reproducing processing unit 6. The recording / reproducing processor 6 converts a digital signal into an analog signal and sends it to the CTL head 9 side. Then, at the start of reproduction, a unique cassette number is written at the head of the CTL area of the video tape. The control unit 20 sends the data of the cassette number to the memory 20a, and stores the data as the identification number data in the number storage area (step S15). Then, when the recording signal is read by the reproducing head 7 as the video tape runs, the reproduced signal is sent to the recording / reproducing processing unit 6. The recording / playback processing unit 6 sends the video playback signal to the image processing circuit 3 and sends the audio playback signal to the audio signal processing circuit, so that the first background image is displayed on the screen of the CRT 4. The accompaniment starts to be emitted from the speaker in synchronization with the background image (step S16).

At this time, the user operates the remote control transmitter 10 while watching the booklet of the song, and inputs the lyrics for each chapter of the song. This remote control 10 is provided with character input keys such as hiragana, katakana, and kanji and music-related symbol input keys, so that it is possible to input optimal characters and symbols in accordance with the lyrics. In this way, when a character or the like is input, the control unit 20 sends the character information to the memory 20a and stores it in the text storage area (steps S17 and S18). At this time, the control unit 20 also stores identification information indicating that it is the first chapter of the music. Since the input is performed while listening to the accompaniment and watching the image on the CRT 4 screen, the operation may be delayed. In this case, the reproduction may be temporarily stopped and the input operation may be performed.

After starting the reproduction of the song of the first chapter recorded on the video tape, the control unit 20 determines whether or not a chapter detection signal has been input (step S19). Here, since each music has an unaccompaniment period of several seconds between each chapter, by comparing this period with a preset time, it is determined that a chapter detection signal has been input at the time of coincidence. . Then, when the background image of the second chapter is projected on the screen of the CRT 4 and the accompaniment starts to be emitted from the speaker, the user operates the remote control transmitter 10 while watching the booklet of the song and operates the second chapter as described above. Enter the lyrics of the milestone. When the characters and the like of the second chapter are input, the control unit 20 stores the identification information and the character information indicating the second chapter of the music in the text storage area of the memory 20a (steps S20 and S21).

Subsequently, when the input of the reproduction signal is interrupted, the control unit 20 determines whether or not the reproduction of the music itself has been completed when the reproduction of the second chapter has been completed (step S22). Here, by comparing with the preset time data, if the non-accompaniment continues for a longer time than the non-accompaniment period between the chapters, it is determined that the reproduction has ended, and the series of editing operations is ended. However, if the interruption of the reproduction is within the time indicating the non-accompaniment period between chapters, the process returns to step S19, where it is determined that the chapter detection signal has been input, and the next chapter is displayed. When the characters and the like of the third chapter are input, the control unit 20 stores the identification information and the character information indicating the third chapter of the music in the text storage area of the memory 20a (steps S20 and S21). After such an operation is repeated, in step S22, when the unaccompanied period is long as described above, it is determined that the reproduction has ended, and a series of editing operations is ended. Thereby, the information of the lyrics corresponding to the video and accompaniment of the music recorded on the video tape of the cassette is stored in the text storage area of the memory 20a.

Next, a reproducing operation of the karaoke apparatus will be described with reference to a flowchart of FIG. When the user wants to use karaoke, the cassette is inserted into the insertion slot of the karaoke apparatus. It is assumed that this cassette has been rewound to the beginning of the video tape. First, when the power key of the remote controller 10 is turned on, the control unit 20 starts operation in accordance with the power-on command, and determines whether or not a cassette has been inserted (step S31). Thereafter, when the user operates the PLAY key with the remote control 10, a reproduction command signal is input to the control unit 20 (step S32). Along with this, the control section 20 starts the operation of the reproduction system including the recording / reproduction processing section 6 based on the reproduction command (step S33). Then, as the video tape runs, the information of the cassette number included in the CTL signal of the CTL area is read by the CTL head 9 and transmitted to the control section 20 (step S34).

Upon receiving the cassette number, the control unit 20 checks the data with the data stored in the memory 20a (step S35). When the recording signal is read by the reproducing head 7 as the video tape runs, the reproduced signal is sent to the recording / reproducing processing unit 6. The recording / playback processing unit 6 sends the video playback signal to the image processing circuit 3 and sends the audio playback signal to the audio signal processing circuit, so that the first background image is displayed on the screen of the CRT 4. The accompaniment starts to be emitted from the speaker in synchronization with the background image (step S36). Along with this, the control unit 20 reads out the character information corresponding to the cassette number being reproduced from the text storage area of the memory 20a and sends it to the recording and reproduction processing unit 6. Then, since the character information is sent to the OSD circuit 5, characters and the like are superimposed on the background image displayed on the screen of the CRT 4 (step S37).

FIG. 3 is an example of a background image, in which characters “Larara Lar La La La” are displayed on the lower side of a ship floating on the sea. Thereby, the user can see the lyrics projected on the screen while listening to the accompaniment, so that the user can practice the music of the first chapter. After starting the reproduction of the song of the first chapter recorded on the video tape, the control unit 20 determines whether or not a chapter detection signal has been input (step S38). Here, when the reproduction of the first chapter ends, there is an unaccompaniment period of several seconds, so that it is determined by comparison with the set time that the chapter detection signal has been input at the time of coincidence, as described above. Then, the control section 20 starts the reproduction of the second section, reads out the character information corresponding to the second section from the text storage area of the memory 20a, and sends it to the recording / reproduction processing section 6. Therefore, the lyrics are superimposed and displayed on the background image projected on the screen of the CRT 4 (step S39).

After that, when the reproduction of the second section ends, the control unit 20 determines whether or not the reproduction ends (step S40). At this time, when the input of the reproduction signal is interrupted, the unaccompanied period is compared with the set time data in the memory 20a. Here, if unaccompaniment continues for a longer time than the unaccompaniment period between chapters, it is determined that playback has ended, and a series of editing operations ends. However, if the interruption of the reproduction is within the time indicating the non-accompaniment period between chapters, the process returns to step S38, where it is determined that the chapter detection signal has been input, and the next chapter is displayed. When the reproduction of the third section is completed, the operation of determining whether or not the reproduction of the entirety is completed in step S40 is repeated. If the unaccompanied music continues for a long time, it is determined that the reproduction is completed. End the playback operation. As described above, the user can see the lyrics sequentially displayed on the screen while listening to the accompaniment for each chapter, so that the user can easily practice the music.

The remote controller 10 may be provided with a screen display key so that the display of the lyrics can be arbitrarily erased or displayed again. When this key is operated during playback in which lyrics are displayed on the screen, the control unit 20 sends a control signal for stopping display to the OSD circuit 5 as in the case of a popular remote controller, and a control signal for stopping display is provided from the background image. Let the lyrics disappear. When the screen display key is operated again, the control unit 20 sends a display control signal to the OSD circuit 5 to display lyrics on the background image. This makes it possible for the user to temporarily erase the song while practicing the song without thinking of seeing the lyrics, and to immediately display the lyrics when they want to see them.

Further, in the above-described embodiment, an example has been described in which video / accompaniment information of a music piece is recorded in advance on a video tape of a cassette, but a karaoke tape is produced by appropriately taking in information from various information sources. You may do so. As an accompaniment information source, a CD can be used, or a received signal of a television broadcast can be introduced from the tuner 1. Internet distribution information may also be used. On the other hand, as the information source of the background image, in addition to DVDs, HDDs, digital cameras, video cameras, etc., the above-mentioned television broadcast signals and Internet distribution information can be used.

When a disc such as a CD or a DVD is used, when the disc is set on a disc tray and a reproducing operation is performed, the CD drive or the DVD drive starts a reproducing operation and sends reproduction information to the digital signal processing unit 13. I do. The digital signal processing unit 13 transmits a digital audio or video signal to the pre-recorded image reproduction processing unit 13. The recording / reproducing processor 13 converts the digital signal into an analog signal and sends it to the recording head 8. Thus, the audio signal and / or the video signal can be recorded on the video tape in the recording mode. Note that the HDD has a built-in disk, but is similar to the above-described CD and DVD. When a digital camera or a video camera performs a playback operation to send playback information to the digital signal processing unit 13, the recording / playback processing unit 13 sends an analog video signal to the recording head 8 and sends the video signal to a video tape. Signals can be recorded.

In the case of a television broadcast signal, if any of the channels is selected, the received broadcast signal is transmitted to the Y / C / A separation circuit 2. Either the audio signal or the video signal to be used can be used. Further, since the distribution information of the Internet is transmitted from the control unit 20 to the recording / reproducing processing unit 13, it is converted into an analog signal, so that it can be recorded on a video tape. When information is taken in from various information sources, the control unit 20 records only the vocal signal from the audio signal. In this way, the video tape stores only the accompaniment signal of the music and the video that becomes the background image. By editing the video tape while playing it as described above, an original karaoke tape can be produced.

In the above-described embodiment, an example has been described in which an original karaoke tape is produced using a popular video cassette. However, a karaoke apparatus using a DV tape as a compact information storage medium is used. You may make a tape. As the information storage medium, a disk may be used instead of a video tape. Although two types of disks are known, a magnetic disk and an optical disk, they are basically the same, and any of them can produce an original karaoke disk. For example, in the case of using a DVD, when the remote controller 10 is operated as described above, the control unit 20 operates the digital signal processing unit 13 and the DVD drive 14 so that the accompaniment information and video from the information source are stored in the DVD. Have information recorded.

Further, by storing the data of the disc number and the character data of the lyrics in the memory 20a in accordance with the information recording, the accompaniment of the music is emitted during the reproduction as described above, and the lyrics are reproduced on the screen. Then, you can practice the music. In this karaoke disk, the period of each chapter from which vocal information has been removed is stored in advance in the memory 20a, and when the control unit 20 reproduces the character information, the lyrics of the song are reproduced based on the chapter detection signal. The lyrics may be displayed on the screen of the CRT 4 in a time width corresponding to the period of erasure. This makes it possible to display the lyrics on the screen with more timing in accordance with the accompaniment sound emission and the display time of the background image.
