Comcast is testing a new streaming set-top that would deliver popular OTT services like Netflix and Amazon Prime Video to its broadband only customers over managed network.

Comcast hasn’t officially commented on the trials, which were first reported by CNBC to be ongoing in several small markets. However, Light Reading did some additional digging with Comcast reps, who quietly told the pub that the trials are using the Arris-made, 4K-capable Xi6, a client that operates the cable company’s X1 video system.

The device would provide broadband-only customers with a pathway to popular OTT services—to a point. It wouldn’t be an OTT streaming device like, say, Roku or Amazon Fire TV, which would let users play a wide variety of apps, including those for virtual pay TV platforms like Sling TV and DirecTV Now.
