DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings with reference to FIG.
Since the method of reproducing a song and the configuration and operation of the ground receiving station on the communication karaoke device side are the same as those of the related art, the entire satellite communication system will be described focusing on the transfer system on the upload side of karaoke data. The host base station 1 is a sending controller facility device, which manages sending of karaoke data and the like, and is operated under the control of a for-profit company that manages and manages karaoke stores nationwide.

The main database 7 of the host base station 1 is composed of a hard disk HD, and the transmission controller is composed of a host computer 8. The host computer 8 records and updates the karaoke data in the main database 7 and transfers the data to the outside by operating an input device such as a key or a program. The main database 7 stores song numbers, song data of each number, lyrics data, videos by genre, and karaoke data including general information.

Further, a main communication line 20 for transferring data to the outside is connected to the host computer 8, and the host computer 8 receives karaoke data from an external editing database via the main communication line 20. This main communication line 20 is NT
The multi-purpose ISDN (registered trademark) of T, and the external editing database corresponds to, for example, an X2000 center database of XXXXXXXXX of a commercial company that manages and manages a karaoke shop. The updated music and updated video data are sent to the host computer 8 from the X2000 center database via the main communication line 20. The main database 7 is composed of a hard disk HD having a capacity of 3 to 4 gigabytes, and music data of karaoke data, video and general information data are sent from the host computer 8 and stored therein.

The host computer 8 is a workstation WS
And constitutes a transmission frame of karaoke data and other data. Also, by operating the keys of the host computer 8 of the WS, general information and billing management information are input to the main database 7 of the HD. A modem 19 for communication network control is connected to the host computer 8, and an output terminal of the modem 19 is connected to one input end of the switching device 21. The karaoke data uploaded from the host base station 1 is the modem 1
9 and the switching device 21 to the public line 2.

The switching device 21 has an output terminal connected to the public line 2 and sends karaoke data to the satellite transmitting station 4 which is a satellite transmitting station on the ground via the exchange station 3. The satellite transmitting station 4 temporarily stores the karaoke data that has arrived until it reaches a predetermined amount, and delays the transmission to the communication satellite 5. This public line 2
Is a 32Kbps NTT digital leased line connected for 24 hours (rented out for a karaoke store).

The host base station 1 is independent of the above-mentioned set of the host computer 8, the main database 7 and the modem 19 and has a backup set 23 which is almost the same as the backup computer, the backup database and the backup modem. A separate backup system will be provided. The output terminal of the spare modem is connected to another input terminal of the switching device 21, and the main communication line 20 is also connected in parallel to the spare computer of the backup set 23. When a malfunction occurs in the set of the host computer 8, the main database 7 and the modem 19, the switching device 21 switches to the set of the spare computer and the spare modem of the spare database and continues the operation.

The backup set 23 performs operations other than transmitting to the satellite transmitting station 4, storage / updating of karaoke data, etc. in the same manner as the host computer 8 etc. In this system, two sets of parallel sets are prepared in case of equipment trouble. Performs linked operation. The satellite transmitting station 4 is a ground facility of a space communication specialized company, is equipped with a large-diameter dish antenna 9, and transmits karaoke data to a geostationary satellite 5 by modulating it to a carrier wave of 14 GHz, for example.

In addition to the public line 2, the computer of the satellite transmitting station 4 of the satellite communication company and the host computer 8 of the host base station 1 are connected by the inspection communication line 22. Inspection communication line 22
Is an INSP of NTT ISDN services that enables communication packets using the INS (registered trademark) net.
(Registered trademark), which is connected as needed, and need not be a dedicated line. INSP of inspection communication line 22
Connects to the computer of the satellite transmitting station of the satellite transmitting station 4 via the INS net 64. The INS net has a transfer rate of 64 Kbps, which is faster than the 32 Kbps digital leased line of the public line 2. The inspection communication line 22 is used as a return test ISDN to promptly perform a failure diagnosis and trouble.

A standby power supply is prepared from the uninterruptible power supply 24 for the operating host computer 8 and the backup set 23 to prepare for an emergency in the event of power failure. The satellite transmitting station 4 receives a predetermined amount of karaoke data from the host computer 8 via the inspection communication line 22 for detecting an error.
Return to. The host computer 8 compares the karaoke data sent to the satellite transmitting station 4 via the public line 2 with the karaoke data returned via the inspection communication line 22, and when they match, a coincidence signal is sent to the public. It is sent to the satellite transmitting station 4 via the line 2. Only when the satellite transmitting station 4 receives this coincidence signal, a predetermined amount of karaoke data which has already arrived and is temporarily stored is modulated with a radio wave of a satellite frequency and transmitted to a geostationary satellite.

When sending karaoke data from the host computer 8 to the satellite transmitting station 4 via the public line 2, a dedicated line is used in order to avoid noise and dropout, at a relatively slow speed of 32 Kbps and for a sufficient time. Forward. Satellite transmitter station 4
When the karaoke data is returned from the host computer 8 to the host computer 8 through the inspection communication line 22 of the loopback test line, the karaoke data is transferred at a relatively high speed of 64 Kbps of INSP. This high-speed transfer is for error detection, and it is relatively fast because it is connected for a fee if necessary.

In the host computer 8, if the karaoke data sent to the satellite transmitting station 4 and the returned karaoke data do not match, it is determined that there is an error,
Again, a predetermined amount of karaoke data of the same block is sent to the satellite transmitting station 4. The same operation is repeated until the coincidence signal is obtained, but if the coincidence signal is not obtained in the second time, it is possible to switch to the backup set 23 because of a device failure. In addition, how much karaoke data as one block is temporarily stored in the satellite transmission station 4, delays transmission, is returned as karaoke data for loopback test, and how many times it is switched to the backup set 23 To decide.

The geostationary satellite 5 receives the karaoke data signal from the satellite transmitting station 4 and frequency-converts 14 GHz to 12 GH.
It is set to z, amplified, and transmitted to the service area on the earth, for example, the Japanese archipelago. The ground receiving station 6 is a BS converter 18 arranged at the focal point of the dish-shaped parapolar antenna 10,
The received radio waves are collected, strengthened, amplified, and sent to the BS tuner 12. The BS tuner 12 detects the received radio wave, restores the original karaoke data signal, and sends it to the karaoke station 13. Since the subsequent operation is the same as the conventional one, the description is omitted.
