In an HD Radio System, what is the role of the Exporter?

In an HD Radio System, the Exporter plays a crucial role in preparing and sending the digital audio information. Specifically, it is responsible for encoding the main program service audio, which includes compressing and converting the audio into a digital format suitable for transmission. After encoding the audio, the Exporter combines this digital audio with additional data services, such as program-related content or supplemental features. This makes it possible for listeners to receive not only the primary audio program but also other useful information while using the HD Radio system.

Understanding the Exporter's function highlights the importance of encoding and service integration in digital broadcasting, ensuring that high-quality audio and supplementary content reach the audience effectively.
