Specifications

Based on PID packet switching technology, the device can multiplex input multi-paths MPEG-2 digital code rate signal.

Description

Transmit Flow Multiplexer

 

Brief introduction

JD-MUX-1100 multiplexer is embedded TS Flow multiplexer self-designed by JZ Company. It is the core equipment for all digital broadcasting TV system. Based on PID packet switching technology, it can multiplex input multi-paths MPEG-2 digital code rate signal, analyze for the input MPTS and add corresponding relevant information and data, generate to new transmit flow. At the same time, EPG, CA and data broadcasting shall be inserted into output code rate. Multiplex 1 path TS and output MPTS; available for auto-generating SI/PSI, with the function of filtering and multiplexing programs and PID. It shall receive 8 paths TS code rate from the ASI interface, and the SI Table data generated from the external SI server shall be inserted into output code rate in real time through the data input channel, so as to realize the value-added services as EPG and data broadcasting. The high performance cost ratio solution is adopted to supply with TS multiplexed and processed. The equipment totally meet the standard of MPEG-2 transmission layer, it shall be widely applied to TV station, digital images monitoring, etc.
