NDS3105A ISDB-T multiplexer

1.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.

2.Features

3. PCR correction and PID re-mapping function
4. NMS supporting, keypad parameter setting
5. Network long-distance upgrading function
6. Two groups separate output
7. Huge buffer, suddenly code stream resistance
8. 188/204Byte transmission stream packet
9. Fully complying with ISDB_T and ISDB_TB standard
10. Supporting hierarchy transmission
11. Supporting each kind of table’s user-define in its transmission layer
12. External 1PPS and 10MHz inputting; supports SFN
13. Separately set the parameters such as time delay for each device when it works as SFM mode
14. Section receiving
15. Number of segments, encoding code rate, modulation mode, time domain interlacing length for each layer and be set separately
16. IIP packet editing and inserting
