Abstract

In an information sending and receiving system in which an information sending equipment and at least one information receiving equipment send and receive information through a transmission medium, a management message is sent from the information sending equipment to the information receiving equipment thereby to create a list of a content code expressing a data message registered on the information receiving equipment side within the information receiving equipment. Then, a data message containing a content code and data is transmitted from the information sending equipment to the information receiving equipment. The information receiving equipment selects a data message by comparing a content code of a data message and a list of its own content code. The content code list may be created within the information sending equipment based on a property value in an answer message from the information receiving equipment.
