Summary:A program type code (PTY) burst signal detection method for a radio data system (RDS) receiver, which can automatically receive an arbitrary information program from another network from the beginning of the program. This detection method detects a PTY burst signal in RDS data, which is indicative of switching of broadcasting of an information program from another network. The PTY burst signal is defined as a signal obtained by transmitting RDS data of a group type 14A comprising an information classification code (Usage Code)=(13) in a second block several times in a short period of time. This detection method respectively compares data of three blocks at least in the 14A group, excluding the first block thereof, with data of the three blocks received earlier, and detects the PTY burst signal when every compared data matches with associated data by a predetermined number of times.
