IPC: G06F17/30
Filed: 1988-10-31
Abstract: PURPOSE:To easily add and change the additional information by adding a mechanism to a transmission system for normal offered information to decide the presence or absence of the additional information. CONSTITUTION:A data base 1 outputs the corresponding offered information to a transmission part 2 based on the ID outputted from an ID deciding part 4 and at the same time outputs the contents of the corresponding next transmission list to a next transmission list memory part 3. While an additional information presence/absence deciding part 7 compares the ID received from the part 4 with the contents of an additional information table 6. If the corresponding additional information is defined in the table 6, the corresponding ID is outputted. A data base 5 outputs the corresponding additional information to the part 2 based on the ID received from the part 7. Thus the affecting range of the additional information can be localized when the information is offered. Then the adding/changing complicacy can be extremely reduced for the additional information.
