188/204 packet length adaptable itself

Adopt big enough cache design, ASI interface support paroxysmal and symmetrical input TS stream, and can equilibrate and reforming the TS stream, enhance the efficiency of output TS stream.

Input data empty packet filtering and output data fill in. 

PRC proofread function, can accurately correct several PCR of input data separately.

Real time inspect and display for the efficient TS stream.

Adaptable itself to filtering circuit design to ensure the excellent suppress capability out of band.

-20dB RF test mouth to monitor IF output.

Fault alarm display

LCD screen display

Network control interface, make centralize management, remote upgrade and maintenance (network management software only for option)

Power-off memory
