Specifications
1. SPTS and MPTS code stream multiplexing2. Two groups separate output
3. Supporting hierarchy transmission
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 6channels input and 2 channels output, the transmission mode is compatible with hierarchy. User can upgrade and control the multiplexer system online through network.
