Digital TS switcher

Introduction

ST300 Digital TV TS switcher is a stream switching system based on ASI signal, which can monitor the stream, PID, form, etc. of the anchor program in real time. It can automatically switch to the alternate stream and program, and even manually switch to the pre-broadcast program in an emergency.

This product is simple and reliable in design, has complete switching strategy settings, and provides dual power supply and modular options, fully satisfying the emergency switching requirements of receivers and multiplexers.

Features

Fully compliant with MPEG-2 TS streaming standard

Support anchor, standby, and pre-broadcast TS stream signal input

Perform three-level detection on the input TS stream signal and make a judgment basis

Real-time stream monitoring, monitoring stream, PID, program table loss, errors and changes, and program descrambling errors

Millisecond-level fast switching, and provide automatic and manual switching, stream-level, PID-level switching and other switching strategies

In the automatic state, the output priority of the system is the main circuit - the backup circuit - the auxiliary circuit 1 - the auxiliary circuit 2

Support intelligent operation functions such as automatic fault recovery, power failure direct/memory, real-time alarm, log recording and query

Supports expandable modular design options to expand more interfaces and functions

Support front panel monitoring, Web network management, unified network management and SNMP multiple management methods

Support dual power supply
