Abstract

A host system for transmitting radio data system (RDS) data includes a host processor and a data processor. The data processor is configured to receive RDS data from the host processor. The data processor is further configured to convert the RDS data into RDS group type data or to store the RDS data. The data processor is further configured to transmit the RDS data to one or more devices outside the host system. The data processor is configured to store the RDS data if the RDS data comprises a plurality of raw RDS group data. A method is also provided for transmitting RDS data from a host system.
