Introduction

Overview

Transport stream multiplexer conforms to the DVB standard with the ability to multiplex and re-multiplex the incoming real-time transport stream, combining the dynamic bit rate control function of GMT + AVS encoder to fully improve the utilization efficiency of frequency band resources and improve the image quality. Realize the data exchange with the encoder to complete the closed-loop dynamic statistical multiplexing: Through real-time analysis of multiple program content, realize the dynamic allocation of the code rate of the different contents of the program, thereby improving the coding efficiency, saving the use of bandwidth .

Characteristics

Support 8 ASI input and 2 IP input, support single program stream SP Statistical multiplexing of TSs and MPTSs

Support 4 ASI output and 2 IP output, support multiple single channel program flow and multi-channel program flow output

A single IP interface can support 512 UDP ports, with a total rate of more than 900Mbps code stream processing capabilities

Input code stream's real time code rate/audio/video code rate, audio/video type and other information analysis and display

Through the centralized clock, PCR resigns and dither correction are performed on each code stream

2 gigabit Ethernet network interface, network manager remote configuration multiplexer, real-time monitoring operation state

High-precision PCR correction

With input stream automatic analysis function, input and output program rate statistics

With 4 or more dynamic statistical multiplexing pools

With empty packet auto-fill and output code rate constant function

With fault alarm display and power-down memory function

Hot backup redundancy dual power supply, hot plug and plug support

Application

Cable digital television broadcasting

Satellite digital television broadcasting

Terrestrial digital television broadcasting
