1. Product Overview
1.1Outline
The 8ASI DVB-T 1RF/2RF Processor is a multinational device intended for multichannel DVB-T
broadcasting. It provides TS re-multiplexing, scrambling, modulating and Up-converting.
Key advantages:
• The processor remultiplexes up to 8 input Transport Streams(TS) and forms a group spectrum
of up to 2 TS in the DVB-T format transmitted at two different frequencies.
• Standard SD/ HD DVB-T receivers and DVB-T TV-sets can be used as subscriber receivers.
• IP output can be used to transport one of the packages via IP network or monitor one of the
packages chosen from output or input stream at your PC.
Оne Processor allows you to organize DVB-T broadcasting of 10-15 programs , as well as a system
for monitoring of channels on your PC. The Processor can replace the two remultiplexers, two scramblers, two DVB-T Modulators and two UP-converters.
1.2 Main features
• Quick replacement of the device in the system without stream rescan.
• Software update/upgrade.
• DVCrypt CAS support.
• EPG, OTA, LCN support, Network Search.
• Adjustable level of the output RF signal.
• Quick replacement of the device in the system without stream rescan
• MPEG-2, MPEG-4/AVC, HD / SD and 3D support.
• Automatic and manual PID insertion;
• Connection to PC: Ethernet (100 MBit /s), RJ45.
• IP output: Supported protocols RTP, UDP.
• IP output can be used to transport one of the packages via IP network.
• Visual monitoring the input and output streams with the free program DVCrypt Ts Monitor via
IP
• IP allows you to record the output ASI stream to the PC for further analysis.
• One or two carriers can be set within 36-850 MHz range, subcarrier frequency can be set with
in 48 MHz.

ASI INPUTS (1-8). Indication of the ASI stream at the relevant input.
If the ASI signal cable is connected to the Processor, but the LED does not light or blinks, it may indicate either of absence of ASI signal, or poor contact or ASI Stream parameters are not correct.
OVERFLOW (1,2) : Each of the two built-in multiplexers has an indicator showing the maximum allow-
able stream is exceeded.
Note. As the input streams typically have a variable bit rate, so at the Processor settings time the
formed steam may be correct, but during broadcast the input streams may increase and cause
spillage of the subscriber images. To avoid this problem on the important channels, it is possible to assign one channel as the one that may be subject to restrictions.

Grounding Terminal
When you connect the Processor to any other device, make sure that it is properly groun ded by connecting this terminal to an appropriate point. When connecting, use the socket and be sure
to use a wire with a cross-sectional area of at least 1.0 mm.
ASI Inputs
Input signals must comply with the EN 50083-9:1998 standard.
ASI Outputs
Two modes are possible:”One spectrum ” and “Two spectrums”.
In the “One spectrum” mode each of the two outputs has the same ASI stream.
In the “Two spectrums” mode one of 4 variants can be set:
1. The first spectrum ASI to the ASI Out 1.
The second spectrum ASI to the ASI Out 2.
2. The first spectrum ASI to the ASI Out 2.
The second spectrum ASI to the ASI Out 1.
3. The first spectrum ASI to the ASI Out 1 and ASI Out2
4. The second spectrum ASI to the ASI Out 1 and ASI Out2
