SUMAVISION EMR Operation Introduction

users can finish encoding, decoding, QPSK demodulation, DVB-S2 demodulation and
descrambling, QAM demodulation and descrambling, DS3 adaptive input/output, QAM
modulation output, ASI multiplexing and routing, IP multiplexing and routing, TS and IP
signal scrambling, etc. To complete the configuration of device successfully, we’ll describe
basic operating processes of EMR through three parts: input section, multiplexing section
and output interface section.
EMR functions can be divided into three parts:
Part one is about the input section . In consideration that each board card can
achieve different input functions, EMR input daughter card can be understood as
a separate device. For example, the encoding card is equivalent to an encoder,
QPSK card is equivalent to a satellite receiver, DS3 adapter card is equivalent to
the adapter, and the five ASI input card functions like the multiplexer.
Part two is about the Multiplexing section which would be realized in multiplexing
screen. The relationship between the input and output can be configured to
achieve the service exchange between the input interface and output interface.
Part three is about the output interface, which output configuretion should be
finished on the right side of the Multiplexing screen.
To complete the configuration of EMR, the above-mentioned three functional modules
should be configured step by step.
5.1.2.1 Input
EMR platform can support several kinds of program sources according to the board cards
inserted, including ASI input and IP input.
ASI Input: ASI input cards are inserted into EMR (for the method of setting,
please refer to ASI input card), to provide ASI input for the platform;
IP Input: the platform’s Gigabit card can provide IP input (Refer to the method of
the Gigabit Ethernet port setting);
5.1.2.2 Multiplexing Setting
The multiplexing screen is shown as Fig. 5-2 Multiplexing Screen of WEB Network
Management. The selected board card on the left is used as input source, which is
multiplexed to the output board card on the right by pressing the Multiplex button.
