4 group ASI output digital TV multiplexer

JXDH****2F Four-In-One Multiplexer, with our company own intellectual property rights, is an embedded digital video communication product, an advanced digital broadcasting TV system TS stream re-multiplexer. Based on the PID package interchange technology, it can multiplex several SPTS, analyze the output MPTS and insect EPG (Electronic Program Guide), CA (Conditional Access) and data broadcast signal into the output TS streams. Choosing any one or several TS streams to multiplex, the Four-in-one multiplexer outputs are four separate groups of MTPS (8 routes, 2 routes for each group). It has service and PID filter and re-multiplexer function and can create SI/PSI information automatically. This multiplexer can receive 8 routes TS streams from ASI terminals. According to the channel, it can insert the SI table, generated on the Sever, into the output TS streams in real time to realize the value-added service like EPG, data broadcast, etc. The multiplexer adopts the solution of smallest volume ( 1U standard chassis) and lowest cost to provide the function of re-multiplexing. It is can be used for TV station, Digital TV inspection, etc.
