JPS636984A - Centralized control system for 'karaoke' (orchestration without lyrics) and its device - Google Patents

Abstract

PURPOSE:To easily use a 'KARAOKE' (orchestration without lyrics) with a video even in any line terminal by collecting plural 'KARAOKE's reproducing machines with videos to one place, controlling and managing, providing a frequency modulator except a general television broadcasting every 'KARAOKE' reproducing machine with video and transmitting by the use of a common audio visual line. CONSTITUTION:One set of the 'KARAOKE' reproducing device with the video is not set to one concert hall but the plural 'KARAOKE's reproducing devices with videos are centralized in the one place, a terminal controller is connected to the television terminal of the respective concert halls by the use of the common audio visual circuit network to play the 'KARAOKE' with the video. The received frequency of the terminal controller is set through an auxiliary controller by a central control unit. Namely, the plural sets of the 'KARAOKE' reproducing devices with the videos are set in the central control unit and the 'KARAOKE' reproducing device with the video which is not operating and a request music of which is stored is selected by a computer and the request music is reproduced according to the command of the computer.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention allows any line terminal within a communal viewing and listening line network to easily publish karaoke with video.

- Traditional technology: Conventional video-equipped karaoke players require one video-equipped karaoke player for every performance venue, and are not easily moved.

Even if the video karaoke playback machines were assembled in a location different from the performance venue, a dedicated line had to be installed between them and the performance venue.

・Problems that the invention aims to solve In order to cover the fluctuating number of performance venues, there was a problem that a large number of karaoke playback machines with video had to be prepared.

・Means for solving the problem In order to solve this problem, - one l) in the performance venue.
J! (Instead of the karaoke playback equipment with images, the karaoke playback equipment with video is concentrated in one place, and using a joint viewing circuit network, the terminal control equipment is connected to the TV terminals of each performance venue, and the video f/ [Play karaoke.

The reception frequency of the terminal control device is set by the central control device via the auxiliary control device.

By effectively operating this system, the number of terminal control devices can be greater than the number of 1-inch video karaoke playback devices.

Furthermore, by making the terminal control device lighter, it is easier to hold it.

A request generated by pressing the key 0 of the active terminal control device (E) is received by polling the auxiliary control device, and is stored in the central control device by polling each auxiliary control device from the central control device. Each control device is a modem @ ■ ■
Data is transmitted via.

The central control unit (C) is equipped with multiple video karaoke playback devices. playback device to computer
■ The frequency of the modulator (2) connected to the karaoke playback device (1) selected by the computer and the frequency of the modulator (2) that is connected to the karaoke playback device (1) is selected by the computer and the frequency of the requested song is controlled by the central control device. The signal is transmitted to the terminal control device that made the request via an intermediary, and the terminal control device's automatic tuner tunes to the transmitted frequency.

As a result, you can enjoy 1Kaizo f=F karaoke.

○Terminal control device: Request l - Keypadzu 1 that manually creates songs
- Modem for communication between fJl and auxiliary control equipment@
and a computer that controls it; and an automatic tuner controlled by the computer; and an amplifier that amplifies the song and singing voice. It operates on commercial AC power and is connected to the terminals of the concert venue's communal listening circuit network. and use it. A distributor [phase] also distributes it to the modem and tuner side.

○Auxiliary control device: Located between the central control tB' device and the terminal control device, it transmits the frequency from the terminal control device to the central control device via the communication modem (■). Send commands to the terminal control device.

It is connected to the community viewing circuit network through a computer that controls the modem and outputs daily and monthly review materials from the central control unit.

○Central control unit: The modem receives the requested song from the auxiliary control unit. ■The receiver receives the video containing the requested song stored in the computer (=F karaoke playback device)
■ Select , determine whether it is currently in use, and if it is in use, select the karaoke playback device with video 1 symbol that contains that song in the pond and play it.

The frequency of the modulation amplifier (2) connected to the reproducing device is then transmitted to the terminal flJv4 device making the request via the auxiliary control device that made the request.

In addition, in order to maintain the joint viewing network, we will retransmit broadcasts from the best broadcasting stations and public broadcasting ■.

It is connected to the communal listening network by a multi-frequency mixing matching box ■.

Refer to the embodiment diagrams (1) and (2).The central control unit is placed at the first public broadcast reception point, and the auxiliary control unit is placed at the first public broadcast reception point. ~ Placed in the front back of 5 hotels,
The terminal control device is placed in the banquet hall where karaoke is held, and the terminal control device is not placed in a specific banquet hall, but is carried to several banquet halls at 1 o'clock, and the karaoke with video can be enjoyed by many parties and many people. I'll get it.

In addition, you can calculate the number of songs played and the playing time based on the daily total, so you can calculate the total number of songs and the performance time.

As described in detail, the invention enables the creation of a joint viewing circuit network without the hassle of transporting a heavy video karaoke playback device from one performance venue to another, and without having to install a complicated video karaoke playback device at each performance venue. By using a light and inexpensive terminal control device, you can easily enjoy karaoke with video.

In addition, video 17 [It is possible to increase the number of terminal control devices than the number of karaoke playback devices 1, the reason is as follows.
It is unlikely that many requests will be received at the same time, and therefore the karaoke playback device with video that has finished playing can be used most effectively by using it in sequence.

Also, since video discs can be centrally managed in one place, the number of songs (
In addition, the karaoke playback device (auto changer type) can have many requested songs and fewer requested songs. It is economical because it can reduce the number of video discs, and by moving the video karaoke playback device away from the performance venue, it is possible to avoid visual problems such as lumps and cigarette tar (= f Karaoke IIr) by moving the video karaoke playback device away from the performance venue. You can.
