MINI MODULAR HEADEND MMH3000
PRODUCT DESCRIPTION
Mini modular headend MMH3000 is compact solution for the distribution of DVB signals in SMATV
and CATV networks in analogue as well as in digital format.
The modern master-slave technology allows to build cost-effective analog TV installations and simplify
a circuitry of SAT IF and terrestrial input signal distribution.
Very flexible DVB-C and DVB-T transmitting system with minimal amount of the modules could be
done due to the original transport stream distribution system.
Communication over LAN, WAN or the Internet using bi-directional TSoIP module significantly extends
possibilities of the headend.
Up to 8 modules could be assembled into the UC380 base unit which incorporates a power supply unit,
RF amplifier and intelligent data bus. The data bus will automatically identify to the required USB link
software, any modules and their relevant position within the base unit with tuning and setting parameters.
Up to 16 base units can be connected together via a data bus.
Where 2 or more programmes are required from the same channel multiplex, the slave MPEG/VSB
modules are available which can be configured to tune additional programmes from a single digital channel.
The programming of MMH3000 can be made locally by handheld control unit by connecting the USB
software link using a PC or remotely through the internet or other communication line using advanced
control and monitoring software. It is also possible to “clone” headends from the settings saved in a
configuration file. The base unit can be installed into a standard 19" rack or stand-alone wall fixing by
reversing the mounting brackets.
The headend is intended for indoor use only.
Suitable for moderate and tropical climates.
