ABSTRACT:
An FM multiplexed broadcasting signal received by an antenna and FM-demodulated by an FM tuner portion is demodulated by a demodulation LSI into a digital signal corresponding to packet data. The digital signal is successively supplied by every packet to a CPU of a receiving portion. The CPU of the receiving portion removes unnecessary data of the received data and then supplies only data required for a CPU of a personal computer via a buffer without delay from the reception. When a transferred packet is a successive reproduction program packet or a time information packet, the CPU of the personal computer calculates latency required before a predetermined data analysis processing is started, and performs data analysis processing in an elapse of the latency. Responsively, reconfiguration of program data is performed and corresponding character information or the like is output to a displaying portion.
