Description

A method of service for motion pictures and voice communication based on internet and a system approximately}

The present invention provides an internet-based video voice call service method and system capable of smoothly realizing two-way communication with high quality video and sound quality through an independent independent window on the Internet.

In general, communication or chatting using the Internet is performed on a communication emulator or a web browser. In the early stages of this chat, many people participated in the virtual space called chat room, and the main method was to communicate with each other. However, in recent years, e-mail that enables two-way or multi-party chat through a pop mail format that is uploaded on a client PC is used. And the chat window method is used a lot.

Furthermore, image chat technology using still images or moving pictures has been announced. Such video-based chat technology has not been recognized as a very useful chat tool for its users. The reason for this is that chatting via chat does not fit well with watching videos on the screen using the keyboard. That is, the image is in progress, but the conversation must be conducted only in the text mode through the keyboard, so the chat is independantly irrespective of the user's emotion.

Such video chat technology can be solved in theory by evolving toward video call technology that simultaneously transmits video and audio.

However, the proposed video communication technology has not been able to provide a satisfactory communication environment. The reason is that in order to provide video call chat to a large number of subscribers, the server for supporting the video call chat should be designed as a very fast and large capacity, and the server for the high speed and large capacity video chat operation was constructed at a high cost. Even if the number of subscribers increases or the number of simultaneous users increases, it is impossible to realistically provide high quality moving image services.

In particular, the video call chat system, which has been in service until now, does not display smooth images because the maximum number of video transmission frames per second that the video chat server can handle is only about 3 to 5 cuts. In addition, the call sound quality is remarkably impaired by the interference in the transmission of the audio signal and the image signal, and the video and audio output to the terminal are not synchronized and appear to be unnatural.

The reason is that the server in charge of the video call must cover all the client terminals that authenticated the connection. Therefore, when the connection is congested, a significant load is applied, which causes a significant decrease in the processing speed. You will not be able to operate normally.

It is an object of the present invention to provide an Internet-based video voice call service method and system capable of smoothly realizing two-way communication with high quality video and sound quality through an independent independent window on the Internet.

Another object of the present invention is to provide an Internet-based video voice call service method and system that can significantly reduce the system construction cost by dramatically reducing the control and management burden of the server for video call.

It is still another object of the present invention that the voice and video are exactly matched in the end to enable seamless 1: 1 video communication, multi-party video communication, and video conferencing, and are capable of connecting a mobile phone with a PC and a PC with a video phone terminal. The present invention provides a method and system for providing Internet-based video voice call.

In order to achieve the above object, the present invention provides a plurality of client terminals waiting for access to a main server through the Internet with an independent independent window driving program, IP information, and member information for a high quality video voice call. If there is a request to open a room in more than 1 or 2 terminals, allow a room to open for each terminal of the unique IP and wait. If there is a request of a room information list for access to the room from another client terminal, the room open information is provided. The client can select the establishment of the open room, and transmits the IP information of the client terminal wishing to connect with the establishment room to the room opening client terminal, and if the room opening client terminal accepts the connection, notifies the acceptance and the end of the waiting state. Provides both IPs for high quality voice calls between And the main server that both the client terminals allow direct interaction with their IP as characterized in that it comprises a member DB to store the information of the members.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a system of the present invention. As referred to herein, the client terminals A, B, and n (15-1, 15-2, 15-i) having multiple memberships are connected to the Internet 14 for IP-based video call chat, which will be described below. It has a configuration that is connected to the main server (10) through. The main server 10 is connected to the member DB 16 for storing and managing personal information of members.

In addition, the main server 10 may be equipped with a real-time language conversion server 13 that enables international text-based conferences through natural language processing, and video calls such as IMT2000 or video telephone, which may be represented as next generation video communication terminals. The gatekeeper 11 may be further connected for connection with the terminal 12.

The video call service process in the system of the present invention configured as described above will be described below.

The main server 10 waits after allowing the opening of each terminal of the unique IP if there is a request for opening the opening of one or more of the plurality of client terminals 15-1 to 15-i. When requesting the room information list from the terminal for access to the room, the room opening information is provided to select one room, and the IP information of the client terminal wishing to connect to the room is transmitted to the room opening client terminal. Function to allow two client terminals to be directly connected with their IP by providing both IPs for high-quality voice call between two parties after notifying the acceptance of the connection and exiting the standby state if there is a connection acceptance from the client terminal. Do this.

The client terminal is connected to the main server 10 so that the video call is possible. First, as shown in FIG. 2A, the client server A 15-1 and the client server B 15-1 are respectively connected to the main server 10. When attempting to access the main server 10 with its own IP information and member information, the user authenticates the connection through the Hwawon DB 16 information inquiry. After that, the two client terminals maintain the connection waiting state.

In this state, as shown in FIG. 2B, when the client terminal A 15-1 requests the opening of the main server 10 to the main server 10, the main server approves the opening of the room, adds a room list to the room information database, and sends a wait signal. Send it out. Accordingly, after opening the client terminal A maintains a standby state.

2C shows a client terminal B 15-2 requesting room information and accessing the room. That is, when the client terminal B requests the room information list from the main server 10 side, the server provides the terminal B with the room list contained in its room information database.

Based on this room information, if the client terminal B 15-2 selects the client terminal A 15-1 and the terminal A 15-1 approves it, the main server 10 as shown in Fig. 2D. Each IP information is transmitted to the client terminals A and B 15-1 and 15-2. Accordingly, the terminal A delivers the conversation progress with the message request acceptance message of the terminal B, and the terminal B notifies the end of the waiting state and prepares the conversation preparation process message.

2E illustrates a conversation information transmission system between two client terminals A and B.

As referred to herein, since the server 10 does not participate in the actual data transmission and only serves to deliver a single information according to the user's request, the server 10 can significantly reduce the load. That is, the actual image, voice, and text data are made between the two client terminals A and B. The main server 10 periodically monitors and corrects or refreshes the mobile IP or the fixed IP of the two terminals. 1: 1 Provide communication environment.

At this time, since the client terminal operates according to the performance of each, if the data transfer between the two terminals is based on the existing method that is made through the server, the communication speed between the two solve the irrationality determined by the low processing speed terminal You can do it.

In fact, between two terminals, only their own IP information update value is called to the server, and no data or segment is transmitted to the server side.

Therefore, since the actual data distributed by the server is distributed, the efficiency is higher than that of the conventional intensive server, and even if the data throughput of the simple information increases, the parallel connection of the server can be extended. It can be upgraded without interrupting service.

2F is an example of construction of a real-time text conversation mode system using international natural language. Here, the language conversion server 13 coupled to the main server 10 is arranged between the two terminals when the IP connection between the two terminals, so that the data processing load is distributed according to the role sharing of the main server. In real-time language translation, another small client-server system is built.

3 shows another embodiment of the system of the present invention. Here, the wireless video terminal 15-3 such as IMT2000, PDA, which is the next generation mobile, is connected to the main server 10 through the gatekeeper 11, which is a public network-to-cable conversion system. You will build a dialogue system.

The system of the present invention allows the main server 10 to connect a plurality of client terminals to a single chat room through IP control management, to update and refresh unique IP information of these client terminals, and to exchange mutual IPs. The IP-switched connection between each other can establish a video voice communication environment for a multi-party conference.

4 is a flowchart illustrating a service method of a video call system according to the present invention in detail.

As referred to herein, the flow of the present invention is largely handled in five steps.

The first step is to build a 1: 1 chat room where high quality video and voice calls can be made by tying a large number of client terminals with independent window driving programs and IP information and member information independently running on a web browser. If one or more of the client terminals request the opening of the client, the terminal is allowed to wait for the opening of each unique IP terminal.

In the second step, when a request of the room information list is requested for access to the establishment room from another client terminal, the establishment room information is provided to select one establishment room.

In the third step, the IP information of the client terminal which wants to connect with the establishment room is transmitted to the establishment client terminal to determine whether the acceptance of the connection is established from the establishment client terminal side.

In the fourth step, if the access is accepted in the third step, after notifying the acceptance and the end of the standby state, both parties provide IPs for direct connection for the high quality voice call between the two parties.

The fifth step is to update the unique IP information of the two client terminals at regular intervals in order to monitor the change in the IP address of the two client terminals connected by the unique IP to maintain the mutual connection state.

As described above, the present invention provides a unique effect of smoothly realizing two-way communication with high quality video and sound quality through an independent independent window on the Internet.

In addition, the present invention can significantly reduce the control and management burden of the server for the video call can reduce the system construction cost.

In addition, the present invention ultimately allows for accurate 1: 1 video communication, multi-party video communication, and video conferencing by accurately matching voice and video, and has a unique effect of connecting a mobile phone with a PC and a PC with a video phone terminal. You can get it.
