Already tightly integrated with Sky's analogue service, it was no surprise that Amstrad partnered with Sky to build a range of set top boxes. Amstrad were one of the first major manufacturers of Sky Digiboxes. Their first Digibox was the DRX100, released in 1998.

Amstrad's DRX550 was one of the "Flow" designs, which Sky introduced to uniform their boxes in 2006. Additionally the "Digibox" trademark was scrapped and standard definition boxes with no recording capabilities were branded simply as "Sky Box."

The Amstrad DRX780 was the freak misfit of the PVR4 line, being the only ARM-based HD unit. Often times, the 780 would find itself being last in the queue for system updates.
