XVideo is supported in some Summit Series/Editions. The incoming video must be synchronous to X server operations. Asynchronous video must first be "captured" by frame grabber hardware.

Multiple incoming syschronous channels can be supported (up to six in the HX Series - the Wall Display series - for example).

The size of the Video Window is scalable in most of the Summit Series packages that support XVideo. In the case of the HX Series, Video Windows can moved across monitor boundaries as long as the monitors involved are covered by the same xscreen, i.e., a SLS or "SingleLogicalScreen," aka "stretched desktop".
