Chapter 1 Overview

SUMAVISION Enhanced Multimedia Route, which can be abbreviated to EMR, is a
new generation multi-media exchange platform. This device, which uses 1U card plug-in
structure, and supports at most 6 boards (cards) as well as dual-power redundancy
backup. The platform integrates multiple functions such as encoding, decoding,
multiplexing, modulation, IP input/output and adaption, can be configured flexibly
according to the different needs of users, and meet the vast number of operators"
demands for integrated devices and multiple functions in the process of digital TV
head-end platform construction sufficiently.

1.1 Network Solution

The typical networking of EMR is shown as Fig. 1-1 EMR Networking Diagram. EMR
platform is matched with many cards to form flexible combinations. EMR platform is
suitable for encoding and decoding, adaptation, and descrambling of reception and
demodulation of the programming stage, and multiplexing, independent scrambling,
adaptation and modulation, and signal switch of the back end. EMR may realize the full IP
networking and backup of various levels and guarantee the efficient, safe and stable
running of the whole system.
Fig. 1-1 EMR Networking Diagram, EMR receives and encodes & compresses the
analog or digital TV video & audio signals; and can also receive and adapt the adaptive
signals such as DS3 and ATM; additionally, it can receive and demodulate the satellite
signals as TS, and transmit TS stream into the multiplex level, then multiplex with EPG
information to become a standard DVB stream, which will be encrypted by the scrambler
