Support XFINITY TV About Digital Encryption

Introduction

Digital encryption technology “scrambles” content provided from programmers to prevent unauthorized viewers from watching pay television services.

To protect their copyrighted content, programmers such as Disney, Viacom and NBC Universal turn to digital encryption technology, which “scrambles” the TV signal. Only the households that subscribe to encrypted channels can display the programming.

We’re required by these programmers to protect their content from unauthorized viewers. Instead of attaching physical blocks to your cable line, we chose, like many other cable and satellite providers, to use digital encryption.

To view encrypted channels, you’ll need a digital device such as a Digital Transport Adapter (DTA), digital cable box or CableCARD. You can get one by calling us at 1-800-XFINITY.
