Description

Communication network flexible accompaniment system. {COMMUNICATION NETWORK MUSIC PLAYER SYSTEM}

The present invention relates to a flexible accompaniment system, and more particularly, to a communication network flexible accompaniment system capable of exchanging a large amount of data such as song accompaniment information, new song data, and control signals using a communication network.

In general, a large-capacity magnetic storage medium for storing MIDI data, audio data, subtitles, and video data is installed in a flexible music cycle in which various song accompaniment information is exchanged through a communication network, and the magnetic storage medium includes DVD, CD-. ROM, hard disk, and the like.

However, since such magnetic storage media are too expensive, manufacturers have tried in various ways to overcome them. However, due to the limitation of the storage capacity, the method of reducing the number of data to be stored and increasing the compression ratio is mainly used.

That is, in the related art, a large-capacity magnetic storage medium is installed (installed within the flexible board cycle) for each communication network flexible accompaniment system. Preferably, the same data is stored in magnetic storage media such as CD-ROM, DVD, and MASK ROM. . In addition, the communication network flexible accompaniment system having the above configuration is described in detail in Korean Patent Publication No. 96-43635 (name: broadcast type karaoke system having supplementary communication channels).

However, these prior arts actually cause huge loss of magnetic storage media because the singular band periods in one karaoke all store the same data. And not only was it the cause of raising the price of the flexible band cycle, but there was a problem that it was not managed efficiently. In addition, in the case of the latest song, it is conventionally composed of a device which directly inputs various video data, audio data, new song data, etc. to each flexible half cycle, so that time loss is also a serious problem.

Accordingly, an object of the present invention for solving the above problems is to provide a communication network flexible accompaniment system capable of exchanging a large amount of data such as video, audio, new song data and control signals of a flexible music cycle using a communication network.

Another object of the present invention is to provide a flexible music note which does not require a large capacity magnetic storage medium for storing song accompaniment information, new song data, and the like.

According to a first aspect of the present invention for achieving the above object, there is provided a server station capable of acquiring song accompaniment information through a variety of flexible accompaniment cycles, a satellite or a modem, and a large-capacity magnetic storage medium; It implements a communication network flexible accompaniment system composed of a control unit for controlling each flexible cycle period and transmitting various data.

More preferably, the server station and the flexible board cycle are separated from each other, and there is no magnetic storage medium such as a DVD, a CD-ROM, a hard disk, or a mask ROM in the flexible board cycle. We implemented a communication network flexible accompaniment system configured to communicate freely upon request.

FIG. 4 is a diagram illustrating various communication data formats according to an exemplary embodiment of the present invention, wherein the server station 102 and the flexible board period 200 operate with each other, and preferably, communication protocols. Such a communication protocol will be easily understood by the description of FIGS. 4 and 5 described below.

Meanwhile, the communication method between the server station 102 and the flexible board period 200 is as shown in FIG. 5.

Referring to FIGS. 4 and 5, first, when the power of the flexible board period 200 is switched on in step 300 of FIG. 5, the instruction stream stored in the program ROM 206 is transmitted to the RAM 208. The program is executed according to the instruction stream transmitted to the RAM 208. At this time, the program proceeding according to the instruction stream is to perform various initialization tasks first.

Thereafter, each of the flexible board periods 200 transmits a respective room number to the server station 102 as shown in FIG. 4 (a), and the server station 102 transmits the room in step 302. It is determined whether the power of the flexible board period 200 is 'on' by receiving a number (Room Number). Here, the room number has a format as shown in FIG. 4 (a), which is composed of 'ROOM ID', 'ROOM NO', 'MODEL NO', and 'CHECK SUM'. At this time, the ROOM ID is a unique number that the flexible half period 200 has, and the ROOM NO means a number of a room in which each flexible half period 200 is to be placed, which has a structure that can be arbitrarily designated by a user. The MODEL NO means a model number of each flexible half period 200, that is, to identify it in a network grouped by different kinds of flexible half periods 200. In addition, the CHECK SUM is for checking whether the transmitted data is correctly transmitted.

Subsequently, if it is determined in step 302 that the power of the flexible half period 200 is 'on', the server station 102 sends ACK data as shown in FIG. 4 (b) in response to step 304. That is, the server station 102 transmits a room number check result to the flexible board period 200 to wait for a music number request. In this case, the ACK data has a format as shown in FIG. 4 (b), which is composed of 'ACK ID', 'ROOM NO', 'MODEL ID', and 'CHECK SUM'. Here, the ACK ID sends a signal corresponding to the ROOM ID of the flexible board period 200, the ROOM NO corresponds to the ROOM NO of the flexible board period 200, and the MODEL ID corresponds to the MODEL NO of the flexible board period 200.

After that, when the flexible board period 200 receives the ACK data in step 304, it enters a ready state for operation. Subsequently, when receiving a selection command from the key input unit 210 of FIG. 3, the flexible board period 200 transmits the song number selected in step 306 to the server station 102. At this time, the data transmitted to the server station 102 has a format as shown in FIG. Next, the server station 102 sends an ACK response corresponding to the data formatted as shown in FIG. 4C, and then configures the data in packets of a predetermined unit in step 308. Here, the data organized in packet units has a format as shown in FIG. 4 (d), and this packet is also variable. Since the flexible panel periods 200 receive the data having the format as shown in FIG. 4 (d), the data packet is assembled and used in step 310. That is, the flexible half period 200 makes the data packet received from the server station 102 into one large packet to be used.

Next, the flexible half cycle 200 determines whether the packet is correctly processed in step 312. If it is determined in step 312 that the packet is processed correctly, the flexible semi-period 200 checks the entire data processed in step 314 and then plays the song in step 316. If it is determined in step 312 that the packet is incorrectly processed, the flexible board period 200 is performed again from step 306 described above.

Here, if the above-described steps 312 and 314 are described in more detail, line data may be incorrectly input as the number of the flexible panel periods 200 that transmit a song request occurs. Therefore, feedback to the data exported in the network card is performed to prevent this. To prevent data from being transferred incorrectly. At this time, if data collides, each flexible board period 200 generates a random time so that a collision does not occur when retransmitting. And if the data transfer value requires the same file (file) in each of several flexible cycle period (200) is usually inconvenient to wait a considerable time if you send again after sending one file. In order to prevent such a case, when the flexible board period 200 receives data, the SONG NO shown in FIG. 4 (e) is reported, and the files are received in a random order according to the PACKET ID. Quit. In addition, a retransmission request is made for an error packet during transmission. In this case, when retransmission is requested in step 312, the server station 102 retransmits only an error packet.

On the other hand, since the score display screen and the palpare according to the score is used continuously, when a song request occurs whenever necessary, only network performance is transmitted. Therefore, for some data, it is possible to maintain the state where it can be stored if necessary by securing an area to be stored after it is called once. In this case, the storage memory may be managed by being divided into a storage area and a temporary storage area.

As described above, the present invention transmits video, audio, new song data, and the like to a server station through a main communication network to complete the data transmission in a short time, so that the user can easily and quickly add and change data as quickly as possible. Can be used. In addition, the server station can overwrite the video, audio, new song data, and various controls at each server station, thereby erasing the magnetic storage media in each song unit cycle, which reduces the price by simplifying the system of the song unit cycle. In addition, there is an advantage that can maximize the convenience of control.
