Product Overview

SFT3504 IP Multiplexer is a SOFTEL’s latest multiplexing model for digital TV broadcasting head-end system with TS output through 4 bi-direction ASI and 3 bi-direction data ports. It can multiplex up to 4 ASI and 768 IP inputs to 4 MPTS, and the amount of ASI output is based on ASI input (ASI port can be used as input or output). SFT3504 IP multiplexer has the functions of auto-generation of PSI/SI information, PID re-mapping, service filtering and PCR adjusting. In conclusion, its high integration and cost effective design make this device widely used in the CATV Broadcasting system.

Key Features

- ASI in/out: max 4 ASI input/output thru 4 bi-direction ASI ports (ASI direction can be defined as input or output manually)

- IP input: 768 IP inputs over UDP/RTP in total (256 IP inputs thru GE1, GE2 and DATA port respectively)

- IP output: 4 IP (MPTS) out over UDP/RTP thru GE1, GE2 and DATA port

- Support bypass output

- Support accurate PCR adjusting, PID filtering, re-mapping and PSI/SI rebuilding and editing

- Huge buffer memory for saving the overflowing code stream

- Web-based NMS management
