PROBLEM TO BE SOLVED: To monitor content information concerning program contents in broadcasting by a one-touch operation only when necessary, without accessing to a content provider. SOLUTION: A content provider 5 (or 7) multicasts content information and second index information before broadcasting a program, thereby storing them in a user's information memory 342. When a broadcast center 1 broadcasts program broadcast signals involving first index information, an extractor 341 extracts the second index information and stores the information in a memory 342 and a reporter 344 reports the reception. When, in this condition, a user sets on a specified key of a PC terminal 32 (or telephone terminal 33), an information reader 343 reads content information with appended second index information corresponding to the first index information and displays the information on a PC. |
