The present invention connects the video channel of the video internet phone terminal to the video content server during the voice call by utilizing the possibility of separating the video / audio channel in order to utilize the screen display device of the video internet phone terminal which is not used during the voice call. When the video internet phone terminal user calls the voice-only terminal user, the video content is transmitted to the video support terminal of one side during the voice call so that the user can view the video content provided by the video content server while making a voice call with the other party. A system and method thereof, and a computer-readable recording medium having recorded thereon a program for realizing the method.

In the present invention, the term "voice-only terminal" includes a terminal that "supports only audio without supporting video" or "supports video but does not want the user to transmit the video."

In a conventional public telephone network (PSTN) or a mobile communication network, a voice-oriented service has been provided, but in recent years, the Internet telephony service, which is widely used, provides a multimedia service including video and data as well as voice.

In a video internet phone, channel information such as a video / audio codec and a channel's Internet Protocol (IP) address and port are exchanged during a call connection. After the call connection process is completed, a call is made by transmitting a video / audio media packet to a channel of the other party. This process will be described in more detail with reference to FIGS. 1 to 3 below.

1 illustrates a case where a calling terminal is a video internet telephone terminal, and FIG. 2 illustrates a case where a called terminal is a video internet telephone terminal. 3 illustrates a video call procedure when both sides are a video internet phone terminal.

As shown in Fig. 1, when the calling terminal is a video Internet telephone terminal A and the called terminal is a voice-only terminal B, the video Internet telephone terminal A (calling terminal) has its own audio channel and video channel for a call connection request. Information is sent to the voice-only terminal B (called terminal) through the Internet telephone call processing device, and since the voice-only terminal B (the called terminal) does not support video, only the voice channel information of the voice channel is accepted when accepting a call connection request. By answering the video Internet telephone terminal A (calling terminal) through the call processing device, only a voice call is made between the calling and receiving terminals.

On the other hand, as shown in Figure 2, when the calling terminal is a voice-only terminal A and the called terminal is a video Internet phone terminal B, since the voice-only terminal A (calling terminal) does not support the video itself when the call connection request Only the audio channel information of the video is sent to the video Internet phone terminal B (the called terminal) through the Internet telephone call processing device, and the video internet phone terminal B (the called terminal) receives its voice channel and the (video channel) when the call connection request is accepted. By responding the information to the voice-only terminal A (calling terminal) via the Internet telephone call processing apparatus, only voice calls are made between the calling and receiving terminals.

In this case, when the called terminal is a video internet phone terminal, there is no video channel information when a call connection request is made from the calling terminal. May not be included. This is shown in parentheses for the image information.

1 and 2, the voice-only terminal corresponds to a PSTN / mobile communication terminal or a voice-only internet telephone terminal. However, since the PSTN / mobile communication terminal cannot be directly connected to the Internet telephone network, it is necessary to use a gateway device that mediates the connection with the Internet telephone network. Therefore, in FIG. 1 and FIG. 2, it should be noted that when the voice-only terminal is a PSTN / mobile communication terminal, it includes a gateway device for interfacing with the Internet telephone network.

On the other hand, as shown in FIG. 3, the basic video internet phone service uses a terminal-to-terminal connection method focused on the concept of a call service.

As shown in FIG. 3, when the calling terminal and the called terminal are video Internet telephone terminals, the calling video Internet telephone terminal A transmits its voice channel and video channel information through the Internet telephone call processing apparatus when a call connection request is made. To the called party's video Internet phone terminal B. In response, the called party's video Internet phone terminal B responds to the calling party's Internet phone terminal A through the Internet telephone call processing device when receiving the call connection request. , Voice and video call is made between the call destination terminal.

Since the video channel and the audio channel are created between the calling terminal (video Internet telephone terminal A) and the called terminal (video internet telephone terminal B) in this way, a third device is intervened to provide various contents. You can't extend services in a way.

Then, look at the types of Internet telephony services in which the third device is involved, and will be described in detail in preparation for the present invention.

An example of the type of Internet telephony service in which a third device is involved is an Internet telephony service (hereinafter referred to as 'first prior art') using an interactive voice response (IVR) device. According to the first prior art, The calling terminal is connected to the IVR device to create a video / audio channel between the calling terminal and the called terminal. Thereafter, when the caller inputs additional information, the connection between the calling terminal and the IVR device is disconnected and the video / audio channel is terminated. Then, the calling terminal and the called terminal are connected to create a new video / audio channel between the two terminals.

The first prior art is a method in which the first device is first connected to the third device (IVR device), then disconnected and then connected again to another device (called terminal), while the present invention provides a state in which a voice channel is maintained connected to the called terminal. There is a significant difference in that the video channel is simultaneously connected to a third device (video content server).

In addition, another example of the type of the Internet telephony service in which the third device is involved is a video conferencing service (hereinafter referred to as 'second prior art'). According to the second prior art, the calling terminal is connected to the video conferencing server. When connected, the video conferencing server receives video / audio data from various terminals participating in the video conferencing and transmits it to the caller.

However, according to the second prior art, since the caller receives the video and the voice of several people who participated in the video conference, it appears that the caller is simultaneously connected with the third devices (terminals of the video conference participant). Like this, the video / audio channel is created between the calling terminal and the video conferencing server, and the video / audio of the participants participating in the call is processed by the video conferencing server. Accordingly, there is a significant difference from the present invention in which the video Internet telephone terminal is simultaneously connected with the voice terminal and the video content server.

There are many cases where you talk to a terminal that supports only voice, such as a telephone terminal.

However, when a call is made with a terminal that supports only voice (voice only terminal), the screen display device of the video Internet telephone terminal is not used for the call, so there is a problem that the screen display device is not utilized during the voice call. Of course, during the voice call, the video internet phone terminal itself performs an operation such as showing the user's screen, but this is only a method of temporarily filling the screen. Never.

In addition, as described in FIG. 3, if the Internet phone service is configured only by connecting the video / audio channel with one counterpart terminal at the same time, the flexibility of separating the video channel and the audio channel from the Internet phone is used. It becomes difficult to create various value-added / application services.

Therefore, in order to utilize the display device of the video internet telephone terminal which is not used during the voice call, the video channel of the video internet telephone terminal is connected to the video content server during the voice call by using the possibility of separating the video / audio channel. If the channel is used for the original call and the video channel can be used as a video information transmission medium, it is expected to be more useful.

The present invention has been proposed to meet the above requirements, and in order to utilize a display device of a video internet phone terminal which is not used in a voice call, the video internet phone terminal can be used during a voice call by using the separability of the video / audio channel.
