Identification code programs
The Program Identification Code , also known as the PI code , is broadcast in Europe by VHF radio stations as an identifier and enables assignment to a program chain. One possible application is the search for alternative reception frequencies for a program, for example for receivers in motor vehicles .
The 16- bit code is transmitted 11.4 times per second within the radio data system and interpreted as a four-digit hexadecimal character string.
The structure of the code is specified in EN 50067 .
- The country / state is coded in the first digit.
- Germany: D or 1
- Austria: A
- Switzerland: 4
- The second position describes the transmission range.
- The third digit is used in Germany to encrypt the state.
- The fourth digit is the program number.
