The PD178016GC-051 incorporates an RDS data decoder section. Whether error correction is performed can
The PD178016GC-051 uses the following eight types of data.
PI is used to identify the program being received.
PS is used for PS display on the LCD panel.
When identical PS data is read two or more times, the PS data is confirmed and displayed on the LCD panel.
About five seconds after the completion of tuning, the LCD panel changes to the PS display.
If PS data cannot be read within about five seconds, the LCD panel changes to the PS display at the point where
Once PS data has been read, if display switching is performed with the DISP key and TP/SK mode is turned on
PTY is used to identify an alarm and display a program type.
If an alarm is read while the device is tuned to an RDS station, the device is switched to radio mode (if in tape/
By pressing the PTY key, the program type can be displayed or a search for a given program type can be performed.
Program types are allocated as follows.
The character string enclosed in parentheses in the program type column is displayed in the 14-segment display
