PROBLEM TO BE SOLVED: To reduce excessive load applied when a reception terminal receives the information to another terminal in a system for transmitting individual information for each reception terminal. SOLUTION: Individual information is transmitted by the section form stipulated by MPEG 2-Systems for every reception terminal. Information contents 802 and the number showing the terminal to be the destination of the information are stored in a section data field 706. At this time, the part of the destination terminal number 801 is extracted and the part is stored in also a section number field 704. In a reception terminal, the part of one's own terminal number and the value stored in the section number field 704 are compared. Only when the both of the values match, one's own terminal number and the whole of the destination terminal number 801 are compared. By using this method, the load imposed on the processing when the information to an other terminal is received is reduced. |
