PDA9908E 8路ASI复用器 PACIFIC DVB Stream Multiplexer – 8-Channel ASI Multiplexer

Description

Broadcast-Grade Professional DVB Stream Multiplexer – 8-Channel ASI Multiplexer PACIFIC​
The ​Huashi PACIFIC PDA9908E​ is a professional broadcast-grade DVB-TS stream multiplexer primarily designed for digital television systems. It supports applications across all DVB-S/T/C digital headend systems. Featuring ​8 ASI input interfaces​ and ​2 groups of ASI output interfaces, it can process ​8 MPTS (Multi-Program Transport Streams) or SPTS (Single-Program Transport Streams)​​ and generate a unified MPTS. The device supports the multiplexing of ​256 PIDs (Packet Identifiers) or 50 programs, along with the mapping, transparent transmission, filtering, insertion, and generation of ​PSI/SI (Program Specific Information/Service Information) tables.

As an ​ASI stream multiplexer, it enables flexible multiplexing of the 8 input ASI streams to the output channels, allowing ​arbitrary reconfiguration of program names, program numbers, and PIDs. The input stream bitrate can reach up to ​270Mbps, while the output bitrate supports up to ​160Mbps. It also supports ​EPG (Electronic Program Guide) insertion, PSI editing, and NIT (Network Information Table) table insertion, making it one of the core devices in cable digital TV headends.

Designed as a ​1U rack-mounted multiplexer​ with a ​19″ standard cabinet installation, the PDA9908E delivers powerful processing capabilities for multiplexing multiple TS streams. Its standardized ASI interfaces ensure reliable stability and high performance, making it an ideal choice for multiplexing and processing digital audio-video stream signals.
