Corresponds to Matsushita Electric's 3DO, SEGA's SEGA Saturn, Nintendo's Super Nintendo, etc. You can use the speaker 18 and CRT 25 of the TV, insert the soft card and play the game without communication.

Next, the detailed structure of the game apparatus 4 will be described with reference to FIG. The game device 4 includes a communication control circuit (I / F) 11 for a modem, a bus 12, a CPU 13,
Work RAM 14 for CPU 13, character generation circuit (PPU) 22 for still images and lyrics, sound circuit 24, R
The OM 26 includes an audio input terminal 30 for various inputs and outputs, an audio output terminal 32, a video output terminal 23, and a control terminal 31. The game device 4 is connected to the communication line 3 via the communication control circuit 11 and can receive a game and various data from the host 2 at a remote place as needed.

The CPU 13 controls the entire game device 4, the data received from the host 2 is stored in the RAM 14, and the voice data is decompressed on the RAM 14 and sent to the sound circuit 24. The audio signal reproduced by the sound circuit 24 is output from the audio output terminal 32 to the speaker 18 of the external TV. The still image and the text signal of lyrics from the (PPU) 22 are sent from the video output terminal 23 to the CRT 25 of the external television.

The ROM 26 stores basic operation programs, character fonts, etc., and is read by the CPU 13. The voice input terminal 30 receives a performance signal from the outside and is connected to the voice output terminal 32. The control terminal 31 transfers various data to and from the external karaoke expansion unit 1.

Next, the detailed structure of the karaoke expansion unit 1 will be described with reference to FIG. The karaoke expansion unit 1 includes a sound source chip 15, a sound source D / A 16, a sound source mixer 17, a sound source RAM 20, a wave ROM 21, a karaoke ROM 27, a microphone terminal 29 of various input terminals, a voice terminal 29, a control terminal 33, and an internal bus 34. To be done.

The tone generator RAM 20 stores the MIDI data received from the internal bus 34, and the tone generator chip 15 generates musical instrument data from the MIDI data based on the tone generator data of the wave ROM 21. Sound source D / A16 is sound source chip 1
The musical instrument data from 5 is converted into an analog signal, and the tone generator mixer 17 mixes the musical instrument data with the voice signal input from the microphone 19 through the microphone terminal 29. The mixed audio signal is output from the audio terminal 28 to an external amplifier or the like. The control terminal 33 transfers various data to and from the external game device 4.

Microphone terminal 29 of the karaoke expansion unit 1
The microphone 19 is connected to the control terminal 31 of the home-use game apparatus 4, the control terminal 33 of the karaoke extension unit 1, the audio output terminal 32 of the home-use game apparatus 4, the television speaker 18, and the karaoke extension unit 1. No. 28 and the audio input terminal 30 of the home-use game apparatus 4 are respectively connected. In addition, the CRT 25 of the display device is used as a home game device 4
1 is connected to the video output terminal 23 of FIG.

Next, the operation will be described in detail with reference to the flowchart of FIG. In step S1, the CPU 13 accesses the karaoke ROM 27 via the bus 12, the control terminal 31, the control terminal 33, and the internal bus 34. Step S2
Then, the CPU 13 connects to the host 2 of the karaoke database that stores karaoke data via the communication line 3 based on the program in the karaoke ROM 27. In step S3, the karaoke data is received from the host 2 and stored in the sound source RAM 20 via the bus 12, the control terminal 31, the control terminal 33, and the internal bus 34.

In step S4, the karaoke data is decompressed and separated into performance data and lyrics data. First, the video system will be described. In step S5, the lyrics data is transferred to the internal bus 3
4, PP via control terminal 33, control terminal 31, bus 12
Transfer to U22. In step S6, the PPU 22 reads font data from the karaoke ROM 27 via the bus 12, control terminal 31, control terminal 33, and internal bus 34, and uses the RAM 14 as a work area at this time. . In step S7, the character generation circuit (PPU) 22 sends the characters of the lyrics to the CRT 25 via the video output terminal 23 and displays them on the screen.

Next, the performance and voice system will be described. In step S8, the performance data is transferred to the tone generator chip 15 via the internal bus 34. In step S9, the tone generator chip 15 reads out waveform data from the wave ROM 21 based on the performance data, and uses the tone generator RAM 20 as a work area at this time.

In step S10, the sound source D / A 16 converts the digital performance data into an analog signal. In step S11, the sound source mixer 17 mixes the singing voice signal from the microphone 19 input from the microphone terminal 29 and the analog signal of the performance data. In step S12, the mixed signal from the audio terminal 28 of the karaoke expansion unit 1 is sent to the game apparatus 4 via the audio input terminal 30. Since the speaker 18 is connected to the game apparatus 4 via the audio output terminal 32, the musical composition and song can be heard from the speaker 18.

The video processing in steps S5 to S7 and the performance and voice processing in steps S8 to S12 are performed in parallel in synchronization with each other. Thus, according to the present invention, it becomes possible to use a home-use game machine as a communication karaoke terminal. The centralized control CPU function and the video processing PPU function are left to the home game device 4, and the karaoke expansion unit 1 is a member mainly required for sound generation.
The sound source chip 15 or the like may be mounted. Users can enjoy not only games but also karaoke at home at low cost.
