A transmitting device discriminating section (101) discriminates a type and a class of a data generating source, and a transmitting format generating section (103) receives a device information code and control data in accordance with the result of the discrimination. A first array area for a reader code, a second array area for a device information code, and a third array area for control data are sequentially arranged, and a bit length of the third array area is reserved by freely varying its effective data length in accordance with device information, thereby a data transmitting format is formed. In a receiving side, a transmitting device discriminating section (203) discriminates next incoming device information in response to the discrimination of a reader code by a reader code discriminating section (202), and a data processing section (204) sets the effective data length of control data against a data monitoring section (205), thereby data processing is performed. <IMAGE> |
