Cisco Prisma IP Element Management System Data Sheet
Description
Wit
h the addition of the new eight channel DVB-ASI encoders and
decoders, the Prisma IP
™
platform now provides for the optimized
transport and interconnection of MPEG-2 streams for your Explorer
®
video networks and for other MPEG-2 digital video content applications.
The Asynchronous Serial Interface (ASI) is a standard developed by the
European Digital Video Broadcasting (DVB) standards association
designed to provide simple transport and interconnection of MPEG-2
transport streams from different manufacturers’ equipment. Equipment
supporting this widely accepted standard today includes MPEG-2
encoders, digital satellite receivers, multiplexers, NVOD/VOD servers,
and QPSK/QAM modulators.
Implementation of the DVB-ASI interface as a line interface plug-in allows
Prisma IP to transport the MPEG-2 streams transparently over a high
speed Resilient Packet Ring (RPR) packet transport network without the
cost of any additional multiplexing or demultiplexing equipment or
processes.
The DVB-ASI Line Interface Cardsets for the Prisma IP Optical Transport
System are two new optical transport line interface cardsets - one is for
ASI input and one is for ASI output. These line interface cardsets will
allow MPEG-2 transport streams that are formatted in the DVB-ASI
standard to be interfaced directly to the Prisma IP System chassis for
transport over a Resilient Packet Ring / Fiber Ring System network. Each
of these line interface cardsets can occupy one of the 12 low-speed line interface slots of the Prisma IP System
M-Series chassis. They can be used in combination with additional ASI line interface cardsets and other low-
speed data and video line interface cardsets to create a flexible common transport system for a variety of digital
and analog signal formats.
Two distinct line interface cardsets are available - one is used as an input or ‘encoder’ and the other is used as an
output or ‘decoder’. The DVB-ASI line interface cardsets have the ability to carry up to eight DVB-ASI MPEG-2
Multi-program Transport Streams (MPTS) to enable transport of MPEG-2 over the Prisma IP Fiber Ring System
network. Each DVB-ASI input card accepts up to eight MPEG-2 digital transport streams in the DVB-ASI format
to be mapped to an Resilient Packet Ring (RPR) Layer 2 packet format. The input card is installed in one of the
12 line interface slots of the Prisma IP System M-Series chassis. The Prisma IP System then multiplexes that
input card’s data stream with other similar data streams to create a high-speed packet optical transport stream.
At the receiving end, the process is reversed - the packet transport stream is switched, and that stream is then
interfaced to a DVB-ASI output interface card that reconstructs the original DVB-ASI formatted MPEG-2 transport
streams and provides multiple DVB-ASI outputs.
