  52 A channel is convertible to another one if the <code>channel_convert</code> algorithm is defined for the two channels.
  53 <p>
  54 Convertibility is non-symmetric and implies that one channel can be converted to another. Conversion is explicit and often lossy operation. <div class="fragment"><pre class="fragment">concept ChannelConvertibleConcept&lt;ChannelConcept SrcChannel, ChannelValueConcept DstChannel&gt; {
