Learn the key differences between a digital set-top box and a digital adapter.
Digital set-top box
A digital set-top box (also known as a digital cable box, digital converter box or digital receiver) processes digital-quality signals. With this box, you can view our on-screen channel guide, which includes access to TV listings, program information, search tools, parental controls and more. You'll also get access to XFINITY On Demand and Pay-Per-View programming.
A digital adapter provides digital-quality signals. When using a digital adapter, you will not have access to our on-screen channel guide, premium channels (such as HBO, Showtime, Starz, etc.), Pay-Per-View or XFINITY On Demand programming.
