Overview
Introduction
This document provides detailed configuration information for distributing
Broadcast File System (BFS) data inband (IB) using an MPEG processor and system
release (SR) 2.7/3.7/4.2.
Broadcast File System (BFS) data inband (IB) using an MPEG processor and system
release (SR) 2.7/3.7/4.2.
Purpose
MPEG processors are quickly becoming a popular choice for systems that deploy
switched digital video (SDV) and ad insertion. Operators might also want to use an
MPEG processor to distribute BFS IB using their Gigabit Ethernet (GbE) networks,
allowing them to remove their ASI distribution networks.

Though the examples in this document use the Cisco Digital Content Manager
(DCM) 9900 as the MPEG processor, the configurations in this document allow your
BFS to work with most any brand of MPEG processor.

BFS to work with most any brand of MPEG processor.
Scope
This document describes two configurations. The first configuration uses a single
DCM to receive the ASI output from the DNCS, transport the BFS IB over a GbE
transport network, and terminate the sessions on a GQAM using its GbE interface.

The second configuration uses one DCM to receive the ASI output from the DNCS,
transport the BFS IB over a GbE transport network, and then uses another remote
DCM to convert the GbE stream to an ASI stream for the BFS QAM.

Note: It is beyond the scope of this document to provide detailed procedures for
setting up the network components and the DCM components of this configuration.
Please refer to the appropriate documentation for those procedures.
