Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-way communication system in which a talker can have a conversation by two-way communication.

[0002]

2. Description of the Related Art A two-way communication system has been studied in various fields toward the establishment of a multimedia information communication society in the 21st century. For example, “Harashima et al., 1995 IEICE General Conference Proceedings, SB-5-5” (conventional example 1), “Yomura et al., 1995 IEICE General Conference Proceedings, SB-4-8. (Conventional example 2), "Shimonoma et al., 1
Proceedings of 1993 IEICE General Conference, SB-4-
2 "(conventional example 3), a research presentation on a multimedia system was made.

In the conventional example 1, VOD (Video on Demand)
), CATV (Cable Television) and other video distribution services and telephone services at the same time, ADSL (Asym using existing metallic cable equipment)
metrical Digital SubscriberLine) system and single-star FTTH (Fiber to the Fiber to the Fiber)
The results of a comparative study of the economic efficiency of the Home) method by application area are shown. In Conventional Example 2, considering the characteristics of image services such as video conferencing, broadcasting, and education, A
A system configuration for a reservation service on a TM (Asynchronous Transfer Mode) network is being studied. In Conventional Example 3, a center prediction type advanced delivery system and a user terminal prediction type advanced delivery system have been proposed, and future problems and the like have been raised.

[0004]

In the past, including the above-mentioned three conventional examples, conventional studies and proposals have focused on only the hardware aspects such as the network configuration, method, components or devices of a two-way communication system. However, the software aspect from the standpoint of the user of this two-way communication system has not been examined. That is, there are very few proposals and discussions about specific contents of services and how to deploy the services, which are performed by using this two-way communication system, and research and development of engineering technology that forgets actual services is preceded. Therefore, there is a problem in that the service provided by the conventional two-way communication system is difficult for users who should enjoy the service in some cases.

For example, a case where a two-way communication system is applied to education. The learner can select the level of the learning content, the learning subject, the learning date and time, etc. according to the degree of achievement of the learning, the subject that is not good, the action schedule including the learning, or the same content can be repeatedly learned. Asking questions, or requesting information about one's level of learning among many learners can, of course, be expected. On the other hand, it is necessary for the educator to educate a large number of learners in response to the above demands of individual learners. However, these things were difficult in the conventional two-way communication system.

There is also a problem when, for example, a two-way communication system is applied to counseling. Counselors respond to the individual wishes of a large number of clients, while clients who want to receive counseling have different wishes regarding the content of consultation and the time and date of consultation that is convenient. Need counseling. However, it has been difficult for the conventional two-way communication system to provide counselors suitable for each client's consultation content and to provide counseling according to the date and time desired by each client.

Further, for example, the bidirectional communication system is a VO.
When applied to the D system, once the client selects a movie or the like, after that, the selected movie is unilaterally transmitted from the center station to the client side and completed. That is, in the conventional system, the client side simply “selects information” and does not have a means for transmitting the most important human emotions and intentions to the other side. The same applies when applied to online karaoke. That is, the conventional system has a problem that it cannot transmit the emotions and intentions of the users to each other, even though it is "bidirectional".

The present invention has been made to solve the above problems, and an object of the present invention is to provide a two-way communication system suitable for application to actual services.
