Descripción
This multiplexer can transfer the head-end single program and multi-program to ISDB-T standard TS as required. Additionally, it also supports PSI/SI table editing and generating, single frequency network and IIP packet editing and inserting. What’s more, the NDS3105A ISDB-T multiplexer can support up to 12channels input and 2 channels output, the transmission mode is compatible with hierarchy. User can upgrade and control the multiplexer system online through network.
