ISDB-T digital TS multiplexer

 

 

 

Outline

 NDS3105A 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 NDS3105A 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.

  

Features   

•   SPTS and MPTS code stream multiplexing
•   PSI/SI information editing and generating; descriptor data inserting
•   PCR correction and PID re-mapping function
•   NMS supporting, keypad parameter setting
•   Network long-distance upgrading function
•   Two groups separate output
•   Huge buffer, suddenly code stream resistance
•   188/204Byte transmission stream packet
•   Fully complying with ISDB_T and ISDB_TB standard
•   Supporting hierarchy transmission
•   Supporting each kind of table’s user-define in its transmission layer
•   External 1PPS and 10MHz inputting; supports SFN
•   Separately set the parameters such as time delay for each device when it works as SFM mode
•   Section receiving
•   Number of segments, encoding code rate, modulation mode, time domain interlacing length for each layer and be set separately
•   IP packet editing and inserting
