Abstract

PURPOSE:To avoid ineffective occupancy of a communication installation by lots of video information sets when the delivery of the video information main body is not on request by leaving the video information main body to a picture memory of a sender side terminal equipment. CONSTITUTION:A sender side terminal equipment 2 stores a video information main body to a picture memory in a terminal equipment with respect to a transmission command from a user and makes 1st communication transferring secondary information representing the content of one or plural transmission object video information sets from the sender terminal equipment to the receiver terminal equipment 3. Then the receiver terminal equipment 3 receiving the information makes 2nd communication of sending a signal requesting the transfer of the transmission object video information main body to the sender side terminal equipment 2 in relation to only the information desired to be received. Moreover, the sender side terminal equipment 2 makes 3rd communication transferring the transmission object video information main body to the receiver terminal equipment 2. Thus, when the delivery of the video information main body is not on request, the ineffective occupancy of the communication installation by lots of video information is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video communication system for delivering video information to specified or unspecified receiving terminals.

[Conventional technology]

Conventionally, in such a system, when a video transmission instruction is received from a user at a transmitting terminal, transmission of the video information body is immediately started, and the video is sent to the receiving terminal or the center device.

[Problem to be solved by the invention]

However, video information has a much larger amount of information than other media and has a long communication hold time, so this method has the following problems.

■Video information that the receiving side does not want is sent without permission at any arbitrary time, which not only puts pressure on the receiving side's image memory due to the amount of information, but also prevents the receiving side from using communication during that time.

■In the end, even for video information that the receiving side does not intend to view, a large amount of video information itself is transferred unconditionally, which is uneconomical for the sending side.

■In order to store and hold a large amount of video information and perform communication processing, the center device requires a huge amount of image memory equipment.

[Means to solve the problem]

In order to solve such problems, a first aspect of the present invention provides a video information communication system that transfers video information from a transmitting terminal to a receiving terminal via a communication network. A first communication that transfers secondary information indicating the content of the information from a sending terminal to a receiving terminal, a second communication that sends a signal requesting transfer of the main body of the video information to be transmitted, and a second communication that transmits a signal requesting the transfer of the main body of the video information to be transmitted. In response to a transmission instruction from the user, the sending terminal temporarily stores the video information in its internal image memory, and first performs the first communication to the receiving terminal. The receiving terminal that receives this makes the second communication to the transmitting terminal only regarding the information for which the video information itself is desired to be obtained, and the transmitting terminal makes the third communication to the receiving terminal.

Further, a second aspect of the present invention is a video information communication method for transferring video information from a transmitting terminal to a receiving terminal via a communication network, in which the first communication, the second communication, and the third communication are performed. In addition, the receiving side of the first communication is a center device, and a fourth communication is provided for listing secondary information indicating the content of one or more pieces of video information to be transmitted stored in the center device, In response to a transmission instruction from the user, the transmitting terminal temporarily stores the video information in its internal image memory and first performs the first communication with the center device, and asynchronously, the receiving terminal communicates with the center device. The receiving terminal performs the second communication to the transmitting terminal only for the information for which the video information itself is to be obtained, and the transmitting terminal performs the third communication to the receiving terminal. This is what I did.

[Effect]

In the present invention, when delivery of the video information itself is not required, invalid occupation of communication equipment by large amounts of video information is avoided.

〔Example〕

In the video information storage and communication system according to the present invention, the main body of the video information remains in the image memory of the transmitting terminal;
Only reference information indicating the intention to communicate is transferred to the receiving side. Since the amount of reference information is small, there is no problem as described in the conventional technology. Unless there is a request for delivery of the video information itself from the receiving side that has processed this reference information, a large amount of video information itself will not be transferred. Furthermore, by specifying a delivery timing in this delivery request, delivery can be performed at a time convenient for the receiving side.
