ABSTRACT:
An FM text-based multiplex broadcasting receiver includes a memory in which an identity code is written, a determining circuit for determining whether or not an identity code which coincides with the identity code written in the memory is contained in the received broadcast, a device for disclosing a keyword having a one-to-one correspondence with the identity code written in the memory, and a display element which cannot receive information services based on data that requires a contract when the determining circuit does not detect that the identity code written in the memory is contained in the received broadcast and which displays information based on data that requires a contract when the determining circuit detects that the identity code written in the memory is contained in the received broadcast.
