Abstract

PURPOSE:To quickly discriminate whether the transmission system of channel frequency AF data is a system A or B, by successively fetching three blocks of AF data of the same program and comparing data of these blocks with one another to detect coincidence. CONSTITUTION:A controller 14 fetches information related to the contents of the same program of a broadcast station, which is received at present, into a memory 15. In this case, in fetching six data (three blocks) into the memory 15, the controller 14 discriminates whether first or second AF data is equal to third and fourth AF data or not and discriminates whether third or fourth AF data is equal to fifth and sixth AF data or not; and the system A is decided to fetch all data of the fourth and subsequent blocks when they are not equal in both cases. When they are equal, the system B is decided to fetch data with the present reception station as the center.
