<h2 id="details">Detailed Description</h2>
<p><code>RadioData</code> is your gateway to all the data available through RDS. RDS is the Radio Data System which allows radio stations to broadcast information like the <a href="qml-qtmultimedia-radiodata.html#stationId-prop">stationId</a>, <a href="qml-qtmultimedia-radiodata.html#programType-prop">programType</a>, <a href="qml-qtmultimedia-radiodata.html#programTypeName-prop">programTypeName</a>, <a href="qml-qtmultimedia-radiodata.html#stationName-prop">stationName</a>, and <a href="qml-qtmultimedia-radiodata.html#radioText-prop">radioText</a>. This information can be read from the <code>RadioData</code>. It also allows you to set whether the radio should tune to alternative frequencies if the current signal strength falls too much.</p>

<p>You use <code>RadioData</code> together with a <a href="qml-qtmultimedia-radio.html">Radio</a>, either by accessing the <code>radioData</code> property of the Radio, or creating a separate <a href="qml-qtmultimedia-radiodata.html">RadioData</a>. The properties of the <a href="qml-qtmultimedia-radiodata.html">RadioData</a> type will reflect the information broadcast by the radio station the Radio is currently tuned to.</p>
