1 Safety instruction
1.1 Before starting using this unit, please be sure to refer to this manual.
1.2 Do not to open the cabinet, otherwise the guarantee to repair are not available. Meanwhile
touching the inside makes you in great danger of electric shock.
1.3 Please make sure to cut off the power supply if you will not use this unit in long term, and do
not use any broken jack, which could result in fire or electric shock.
1.4 Wet hands are forbidden to touch the power jack, to avoid risk of electric shock.
1.5 Please pull the plug itself instead of the wire when you pull out power plug,.
1.6 Any thing flammable and metal or liquid, which will destroy the unit, must be kept out the
box.
1.7 Do not place this unit in a location near a heat source such as radiator or air ducts, or in a
place exposed to direct sunlight, excessive dust, moisture, rain, mechanical vibration.
1.8 Keep the device working in a good ventilative environment, if not the destruction will occur.
1.9 Please keep the packaging for the safety of transit.
NOTE: After all parameters are set up, please press the LOCK button. When LCD display is dark, the
protection function takes effect.

2. System composition and operating principle
2.1.System composition
THE SYSTEM CONSISTS UNITS OF THE FOLLOWING CHART
2.1.1 ASI input interface
ASI input, it’s MPTS (Multi-Program Transport Stream) or SPTS. The useful data will be output and
null packet、 needless data will be filtered after processing.
2.1.2 Program stream multiplexing
Multiplex the selected program of different interface, the below table will be available or updated
while multiplexing, then insert them into MPTS.
● PAT
● CAT
● PMT
● NIT
2-1
2.1.3 Data output interface
A. ASI output interface
ASI output, it’s MPTS (Multi-Program Transport Stream) or SPTS. The output bit rate could be set up
to 80Mbps.
B. E3/DS3 output interface
E3/DS3 output, DVB TS, standard: G.703
The output bit rate is fixed.
2.2 Operating principle
AD2700 TS REMULTIPLEXER multiplex 2~8 MPEG-2 SPTS or MPTS into 1 MPTS, the null
packet or needless packet will be filtered. The PID could be reset if necessary and pick-up the relevant
information for further processing.
The processed program specific information (PSI) and service information (SI) is integrated with local
data. Each input consists of SPTS, each program includes video、audio、auxiliary data.
Re-identify the program clock reference (PCR) with system time clock (STC).

3. Main features
● Multiplex 8 inputs (ASI) SPTS or MPTS, multilevel multiplexing is available
● Input date bit rate: 216Mbps(max)/channel
● Output bit rate: 2Mbps~120Mbps(tunable), available bit rate is up to 120Mbps
● PID filtering and PID re-setting, the user could add 、delete the program as they wanted, and
mapping the PID of selected program automatically. Support user-defined program’s PID and
input through channel
● ETHERNET interface, it could carry out the parameters setup and supervision from remote via
network management unit.
● Statistic multiplexing
● PCR correction
● Insert network parameters and change program name
● MPTS automatic analysis
● Statistic input/output program bit rate
● Empty packet automatic filling and output bit rate invariablenes
● 188 and 204 packet automatic identification
● Output TS packet is optional (188 and 204)
● E3/DS3/SPI is optional
● Failure alarming
● LCD display to carry out system status supervision and system parameters setup
● Power off memory
