Abstract

A radio broadcasting system, transmitter, receiver, method and signal are provided wherein a program signal is combined with a data signal, the data signal not only includes information on an indicated program signal, but also data of a data service and information on the data service, such as, an identification of the data service, alternative frequencies, information on related data services etc. In this way, it is possible to broadcast the data service on a network differing from the network broadcasting the program signal. This is of particular use in the Radio Data System.

Claims

1. A radio broadcasting system comprising a transmitter and a receiver for transmitting and receiving at least one program signal and a data signal, the data signal comprising information pertaining to an indicated program signal, characterized in that the data signal further comprises data of a data service and information pertaining to said data service.

2. The radio broadcasting system of claim 1, characterized in that the data signal is organized in groups having a group type code for distinguishing between different types of data and groups having the same group type code are used for transmitting the data of said data service and the information pertaining to said data service.

3. The radio broadcasting system of claim 2, characterized in that a group comprises a data bit for distinguishing remaining data bits as either comprising data of the data service or information pertaining to said data service.

4. The radio broadcasting system of claim 1, characterized in that the information pertaining to said data service comprises information on a related data service.

5. The radio broadcasting system of claim 4, characterized in that the information pertaining to the related data service comprises switching information for switching the tuning of the receiver to a frequency for receiving the related data service.

6. A radio broadcasting transmitter for transmitting at least one program signal and a data signal, the data signal comprising information pertaining to an indicated program signal, characterized in that the data signal further comprises data of a data service and information pertaining to said data service.

7. A radio broadcasting receiver for receiving at least one program signal and a data signal, the data signal comprising information pertaining to an indicated program signal, characterized in that the data signal further comprises data of a data service and information pertaining to said data service.

8. A radio broadcasting method for transmitting and receiving at least one program signal and a data signal, the data signal comprising information pertaining to an indicated program signal, characterized in that the data signal further comprises data of a data service and information pertaining to said data service.

9. A radio broadcasting signal comprising at least one program signal and a data signal, the data signal comprising information pertaining to an indicated program signal, characterized in that the data signal further comprises data of a data service and information pertaining to said data service.
