Title: Broadcasting receiver
Inventor: OMORI YOSHIO
IPC: H04H20/00
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent the time delay or advance of broadcasting to original time by thinning predetermined data among the data of the output signals of a storage part, based on the delay time at the time of switching from the output signals of a reception part to the output signals of the storage part. SOLUTION: At switching to FM broadcasting signals, a controller 9 controls the time of reading the data of the FM broadcasting signals from the storage part 4, based on the time difference of DAB signals and the FM broadcasting signals measured in a delay time measurement part 5. The read time is controlled by changing the address of the data stored in the storage part 4 based on the delay time. Thus, the FM broadcasting signals outputted from the storage part 4 and the DAB signals outputted from a first reception part 2 are outputted from a switching part 6 in a state without delay times. By controlling a read speed by the storage part 4 and performing output without the delay time to the DAB signals, even if broadcasting signals are switched, interruption or repetition or the like does not occur.
