Program and System Information 
Protocol Configuration for System 
Releases 2.5, 2.7, 3.5, 3.7, 4.0, 4.2, 
and CV 3.4 
 
Overview 
Introduction 
Program and System Information Protocol (PSIP) is a type of system information 
(SI) that is generated by the broadcaster and delivered in-band with MPEG 
content. Cable-ready digital devices ("hosts") use PSIP to receive navigation and 
guide information for unencrypted digital channels. The September 2003 FCC 
Report and Order requires that broadcast PSIP be carried inband without 
modification to enable PSIP navigation for hosts that do not have a PowerKEY
®
 
CableCARD™ module, or point-of-deployment (POD) module, installed. 
PSIP support is only required for unencrypted content, and PSIP is not used to 
carry SI for encrypted content. Cable-ready hosts equipped with a PowerKEY 
CableCARD module can decrypt content and receive out-of-band (OOB) SI data 
in order to navigate and display encrypted MPEG content. 
 
Purpose 
This document explains how to configure the network to carry unencrypted 
MPEG content with unmodified PSIP configured on the DNCS as a Third-Party 
Source. This document also describes the headend configuration needed to 
support delivery of services with broadcaster-generated, in-band PSIP on 
unencrypted digital broadcast streams. 
 
Audience 
This document is written for headend engineers, system operators, technical staff, 
and Cisco Services Engineers.
