TRANSCRIPT
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.
Programming of MMH3000 could be made locally by handheld programmer and software or remotely through internet or other communication line using advanced control and monitoring software. Also is possible to “clone” headend’s settings from the saved configuration file.
Almost all parameters of the modules are controlled by programming via CMH data bus.
It is necessary minimal amount of additional external equipments for installation of the headend.
Mini modular headend MMH3000 consists of:
DVB-S/S2, DVB-T/T2, DVB-C, DVB-ASI & MPEG2 TS, TSoIP processing modules into VSB or DSB analogue channel DVB-T, DVB-C and analoque VSB TV modulators TV channel converting module DVB-S/S2, DVB-T/T2 & DVB-C, TSoIP processing modules to DVB-T/C channels FM & DAB radio amplifier TSoIP bi-directional interface module MPEG2 encoder control software and accessories
