Multiplex broadcast receiving method and receiver which can easily update the preset contents of classification information, such as a program type, in an RDS broadcasting. The RDS receiver is constituted by a memory control section for storing the classification information (PTY code) demodulated from RDS broadcast waves which are being received into a PTY memory; the PTY memory for storing the classification information; and a station selecting section for selecting a station of the multiplex broadcast waves regarding the classification information by reading out the classification information from the PTY memory. This enables the use of the classification information of the broadcasting station being received as it is, so that the user can store the favorite program type by a simple operation.

Multiplex broadcast receiving method and receiver with program type

A receiver with an automatic receiving-station switching function for automatically switching a current receiving frequency from a reception frequency of a broadcast wave in reception to a reception frequency of a broadcast wave of another station, which is in a good reception condition, when a reception condition of the former broadcast wave becomes poor. After detecting deterioration of the reception condition of a received signal, when the level of a detected signal obtained by detecting the received signal is kept equal to or lower than a threshold value for a predetermined time or longer, the receiver sets muting means to a signal cutoff state to stop the audio output before the activation of the automatic receiving-station switching function. Even if the reception condition becomes poor, the muting means does not cut off an audio signal until the low level of the audio output in the currently receiving broadcasted program continues.
