<title>Chromecast WebDriver Receiver v1</title>
<!--

This is an archived version of the receiver from v1 releases.
In v2, we break compatibility and register a new default app ID that has new
capabilities.

This version only took a URL as a parameter, and could only host content in an
iframe. It is registered to receiver app ID B602D163, the v1 default app ID.
