USB2.0 stream analyzer remark：
    USB 2.0 is the best instrument for engineer developing and debugging outside。 It makes the STB engineer’s work of collecting stream easily without taking large bulky and expensive stream analyzer, just with stream analysical box and notebook to finish collecting, analyzing and debugging –C and ASI stream. The most important is that engineer can collect suitable practical envirnoment stream in the home and do not need go the operator's headend machine room。USB stream collecting box matching the DVBCN stream analyzing software provide the users mobile stream analyzing platform. It is not only with the basic function of stream applying analyzing, modularized design, analysis of EPG, broadcasting analysis of DC data, analysis module of MPE data broadcasting, also supporting data analyzing of inland main trend data broadcasting headend.

Main function:

1. Compliant with DVB-C standard
2. Support muti-programme TS stream recoding with maximum 80 Mbps speed, and the recording space is not limited( depend on the HDD space)
3. Support recording all-stream, fixed muti-service stream, fixed muti-PID stream, fixed SECTION stream
4. Support 188/204 byte transport stream software indicating signal quality, display C/N, BER, total and wrong package index
5. LED display the signal locking and USB connection state, small volume, light weight, convenient carry, full aluminium alloy case, long and continuous work time
6. Plug and play, hot swaps, convenient and practical

Main application:

1. Receive cable operation nets QAM signal, convenient for STM engineer testing and analyzing
2. Analyse and monitor the real-time stream of cable television network, receive and analyse the standard EPG professionally, record the complete TS stream after QAM demodulation, realize seamless stream replay with TS play card
3. Demodulate and record the single program after QAM demodulation, analyse the second DVB development stream
