COL52122D Digital tv ISDB-T video multiplexer

Outline

COL52122D ISDB_T multiplexer is a TS re-multiplexer developed to adapt Japan and those South American

countries such as Brazil and Argentina.It supports 2 separate multiplexers which are fully complying with ISDB-

T standard. 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 ISDB-T multiplexer can support up to 6 channels input and

2 channels output, the transmission mode is compatible with hierarchy. User can upgrade and control the

multiplexer system online through network.
