Abstract
PURPOSE:To quickly discriminate whether the transmission system of channel frequency AF data is a system A or B, by fetching first and second blocks of AF data of the same program and comparing data of these blocks with each other to detect coincidence. CONSTITUTION:A controller 14 fetches first and second blocks out of information related to contents of the same program of a broadcast station, which is received at present, into a memory 15. The controller 14 discriminates whether second AF data out of two blocks fetched into the memory 15 is equal to third and fourth AF data or not, and the system A is decided to fetch all AF data of the fourth and subsequent blocks into the memory 15 when it is not equal to them. When it is equal to them, the system B is decided to select and store AF data of groups with the reception station, which receives data at present, as the center.
