Understanding PPStream
<p>It's <a href="http://kan.pps.tv/web/pps.js" rel="nofollow">http://kan.pps.tv/web/pps.js</a> </p>

<p><code>
PPStream.prototype.pps_width="400px";
</code></p>

<p>The PPStream is never declared, is this PPStream object purely generated by 'prototype' way? I know how 'prototype property' works.</p>

<p>Thanks.</p>
