ABSTRACT

The open data applications (ODA) are a development for the Radio Data System (RDS) Standard. Achieving a worldwide consensus for the precious commodity of RDS data groups seemed impossible until the idea for ODA was developed. An ODA may use type A and/or type B groups, however it must not be designed to operate with a specific group type. It is possible that multiple ODAs can reside on a single transmitter or network. The problem was that very few RDS data groups were remaining that could be defined for a new application. In effect, the development of the ODA has given the RDS Standard a real breath of life. Datacasting services may now be started very easily without fear of crashing with some other system. Obviously, only a fixed amount of data may reside within the constraints of the RDS system. It is the transmission operator who must trade benefits of increased income versus the needs of the station.
