Audio System: Other Kia Rio III

Multicasting

HD Radio FM stations are able to broadcast multiple digital program streams(channels) over a single FM frequency. For example, a HD Radio FM station can run a main channel of music and a sub channel of news(or even two different music channels) at one frequency. But only the program content of the main channel is also broadcasted analog.

HD Radio signal delay

"To overcome the delay that digital systems inherently produce, HD Radio technology first uses the audio signal of the analog broadcasting when you tune to an AM station or to the main channel of a FM station. After that, the system will blend from analog to digital signal. Normally, this blending is very smooth. If you experience a skip in program content of several seconds, the radio station has not implemented HD Radio broadcasting correctly. This is not a problem with your audio system. Due to the fact that sub channels are only broadcasting digital, blending from analog to digital signal is not possible if you tune to a sub channel. In this case playback of the sub channel starts after several seconds, this is a normal function."

Automatic switching between digital and analog broadcasting

"If the reception of the digital signal is lost, the system switches automatically to the analog signal. As soon as the digital signal is available again it will switch back. Due to the fact that sub channels are only broadcasted digital, first the system mutes playback if you have tuned to a sub channel and the digital signal is lost. Additionally, the main line shows the message No HD signal in place of station name. Second, after 1 minute with the digital signal lost, the system will automatically tune to the analog signal of the corresponding frequency."

Text based information

HD Radio stations are able to broadcast text based informations, e.g. station name, song title and artist name. The Driver Information System is able to display these informations.
