INTRODUCTIONS
IMT914 Eight-Channel IP to DVB-T Multiplexing Modulator Module is the latest IP to DVB-T modulator developed by Trochilus, which integrated with multiplexing function at the same time. Each IMT914 daughter module can work independently, due to the combining of 4*multiplexing modules, >and 4*DVB-T modulation modules. It supports up to 256-channel IP MPTS/SPTS (per daughter card) input with its GigE port and 4*adjacent carriers (30~860MHz) output through the two RF output interfaces.
This IMT914 IP to DVB-T Multiplexing Modulator Module was designed in slot structure and being allowed of a maximum 3-module insertion into one device simultaneously. Its excellent and high integration, and powerful performance make it quite a good choice for the new generation of digital TV systems.
