A radio data receiving device includes a memory, and a processor operatively connected to the memory, wherein the processor is configured to receive a zeroth
stream based on a first
frequency band about a
radio data system (RDS), receive a first
stream based on a second
frequency band in which the RDS is extended, receive a second
stream based on a third
frequency band in which the RDS is extended, receive a third stream based on a fourth frequency band in which the RDS is extended, and provide a service about RDS data based on at least one of the first stream, the second stream, or the third stream.
