SOLUTION: When a CPU 27 is in operation based on a computer program stored in a program RAM 42 and sent in a character multiplex broadcast signal form and reply data from a viewer such as a questionnaire are sent to a collection station through a MODEM 38, a line connection section 39 and a telephone line 40. A transmitted program identification number is stored in the RAM 42 and when reply data are sent as incoming data, the program identification number added to the data is sent. Thus, when reply data come from viewers of different character multiplex broadcast programs, the data collection station easily recognizes a cross reference between the reply data and the program to improve the job efficiency of the data collection station. |
