Introductions

IMA918 Eight-Channel IP to ATSC Multiplexing Modulation Module is the latest IP to ATSC modulator developed by REGEN, which integrated with multiplexing function at the same time. Each IMA918 daughter module can work independently, due to the combining of 8*multiplexing modules and 8*ATSC (8VSB) modulation modules. It supports up to 256-channel IP MPTS/SPTS (per daughter card) input with its GigE port and 8*adjacent carriers (40~860MHz) output through the two RF output interfaces.

This IMA918 IP to ATSC Multiplexing Modulation 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.
