What is RDO?
RDO stands for Radio Data Object. It is a standardized format for representing and exchanging data over radio Communication networks. RDO is a key component of the Digital Audio Broadcasting (DAB) standard, which enables high-quality digital audio transmission over radio frequencies.
Key Features of RDO
- Data Encapsulation: RDO encapsulates various types of data, including audio, text, images, and metadata, within a standardized format.
- Efficient Transmission: RDO utilizes efficient coding and modulation techniques to ensure reliable data transmission over radio channels.
- Interoperability: RDO is designed to be interoperable across different DAB receivers and transmitters, ensuring compatibility and seamless data exchange.
- Flexibility: RDO supports various data rates and transmission modes, allowing for adaptation to different Network conditions and application requirements.
RDO Data Structure
RDO data is organized into a hierarchical structure, consisting of:
- RDO Packet: The basic unit of data transmission, containing a header and payload.
- RDO Service: A logical grouping of RDO packets, representing a specific data stream or service.
- RDO Ensemble: A collection of RDO Services, providing a comprehensive set of data offerings.
