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 Network solution Diagram.

In Fig. 1-2 EMR Network solution 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 them into the multiplexer, then multiplex with EPG information
to become a standard DVB stream, which will be encrypted by the scrambler and CAS,
and modulated by the modulator and finally transmitted on HFC network.
