catv digital headend multiplexer

Product Overview

Description

CATV digital headend multiplexer

Outline

NDS3107G Tuner Input Multiplexer is the latest demodulation and multiplexing device for digital TV broadcasting head-end system with TS output through IP port. It can multiplex up to 16 channels Tuner and 2 ASI input to IP (MPTS). This multiplexer has the functions of supporting auto-generation of PSI/SI information, PID re-mapping, and service filtering.

BISS function embedded will carefully descramble tuner input programs. In conclusion, its high integration and cost effective design make this device widely used in the CATV Broadcasting system.

Key Features

l  Support 16 FTA DVB- S/S2 (DVB-C/T/T2/ ISDB-T/ATSC optional )input, 2 ASI input

l  Support DisEqc function

l  4 IP output (MPTS) over UDP, RTP/RTSP protocol

l  2 GE mirrored output, up to 850Mbps

l  Support PID filtering, re-mapping

l  Support PSI/SI rebuilding and editing

l  Support “Null PKT Filter” function

l  Support Web operation
