Support XFINITY TV Digital Boxes vs. Digital Adapters

Introduction

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.

Digital Adapter

A digital adapter provides digital-quality signals. When using a digital adapter, you will not have access to our premium channels (such as HBO, Showtime, Starz, etc.), Pay Per View or XFINITY On Demand programming.
