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

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.
