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.
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
- IIP packet editing and inserting
