2. Description of the Related Art It has been common to use a device having a transmitting device function and a receiving device function as an information transmitting device serving as a base station or a terminal station of a conventional wireless network. Therefore, the transmitting terminal and the receiving terminal actually perform information transmission after establishing bidirectional wireless links.

In such a conventional wireless network, information is correctly transmitted from a device which is a source of information (hereinafter referred to as "source device") to a device which is a destination of information (hereinafter referred to as "recipient device"). In order to determine whether or not the receipt has been completed, the receipt confirmation information (hereinafter referred to as “ACK information”) is returned from the information reception destination device to the information transmission source device.

If the source device does not return the ACK information from the destination device, it determines that a transmission error has occurred, and the source device retransmits the information.

Further, in the information transmission method in the conventional wireless transmission method, overhead information is added to the information to be transmitted and transmitted, and in this overhead information, the identification information of the information transmission source device or the information reception destination device is included. The method of adding was taken. The information receiving device receives the signal sent from the information transmitting device, refers to the receiving device identification information in the overhead information included in the signal,
It is determined whether or not the device identification information of the device is described, and if the device identification information of the device is described, a method of passing the information to an upper layer is used. It was

Before the information is transmitted, the source device and the destination device need a method of specifying the relationship between the available source device and the destination device in advance. Generally, a method has been used in which a transmission device that can be used in one network is registered in advance and then wireless transmission is performed.

A method of registering a transmission device that can be used in a network is shown in International Publication WO00 / 74316. This publication discloses a method in which a transmission device registers desired network ID information to enable communication in the wireless network.

[0008]

In the conventional radio transmission system as described above, it is a prerequisite that all the transmission devices have the transmission / reception device capability. Therefore, even in the transmission device that only receives the data, The transmission function was added, leading to an increase in user costs.
For example, when displaying video information from the set-top box on the monitor display, the wireless transmission device connected to the set-top box becomes the transmission device, and the monitor display becomes the reception device. The monitor display transmission function was not always necessary.

Further, when the ACK information is returned from the receiving device to the transmitting device as in the conventional wireless transmission system, the receiving device side needs the transmitting device function. Further, in such a wireless transmission system, since the ACK information is wirelessly transmitted, the throughput on the transmission path tends to decrease. Further, when another transmission device exists in the same space or in a close position, it is necessary to return this ACK information so as not to affect the information transmission of the other transmission device. However, the communication control method of retransmitting when the ACK information is not returned as in the conventional method is a delay in accumulating delay in the information collected by the receiving device when transmitting information with real time. There is a problem that it is difficult to realize real-time transmission of information.

Further, in the conventional information transmission method, the following problems occur due to the increase of the transmission destinations. That is, in a conventional information transmission system that performs information transmission by describing information of a transmission source and a reception destination, when the information is transmitted from the transmission source device to a plurality of reception destination devices, the reception destination devices are individually Therefore, there is a problem that it becomes difficult to specify the receiving destination device when the number of destinations becomes huge.

Further, in the conventional information transmission system, in order to collect the information for specifying the transmission source device and the reception destination device, it is necessary to register the transmission devices that can be used in one network in advance. is there. Therefore, when the number of transmission devices registered in the corresponding network increases, there is a problem that the management of the information of those transmission devices becomes complicated.

In the method of exchanging network IDs disclosed in International Publication WO 00/74316, a method of exchanging information between a sender and a receiver of a network ID has been shown. Also needed information transmission means. It should be noted that this publication describes the content of the method of exchanging and configuring the network, but does not mention the method of adding the exchanged network ID information to the information transmitted and received.

The present invention has been made to solve the above problems, and an object of the present invention is to make it possible to arbitrarily provide at least one of a transmission function and a reception function to an information transmission device. The purpose of the present invention is to provide an information transmission system. Another object of the present invention is to provide an information transmission system that enables information transmission without using conventional ACK information. Still another object of the present invention is to provide an information transmission system that enables information transmission without designating a recipient of the information. Still another object of the present invention is to register transmission devices available in one network in advance,
An object of the present invention is to provide an information transmission system that enables information transmission between arbitrary transmission devices in a network.
