With the old 722, it was called a sling adapter, not technically a box. It looked like a mesh grating and it connected to a USB port. It was required on the 722 if you wanted to watch content from the 722 remotely.
A slingbox is a related but different animal.
The Hopper3 and HWS both have sling functionality built in.
