Monitor keeps watch
over Chinese satellites
China Broadcast Satellite Co (CBSAT) has selected the Pixelmetrix DVStation monitoring platform to upgrade its satellite monitoring in Beijing
The DVStations are deployed in the satellite control room to continuously monitor the quality of digital video downlink and uplink signals to verify the correct service performance in a real-time, all-the-time manner. The same platform also allows in-depth troubleshooting if anything goes wrong.

CBSAT decided on the DVStation platform because of its flexible and comprehensive features including QPSK signal monitor, On air content validation (OCV), video thumbnails, TR101 290, PCR jitter analysis, and extensive measurement logs which allows historical data to be retrieved for more in-depth analysis.
"Compared to other monitoring systems available on the market, CBSAT engineers choose the DVStation platform because a similar system has been deployed by SARFT 573 satellite station since 2002, and it has been proven to be a highly reliable and scalable solution".
"Most importantly, it is a cost effective solution as it provides complete satellite QPSK signal and Transport Streams monitoring within a single box solution", says CB Lau, Pixelmetrix Regional Sales Manager, for Greater China.

In the past, CBSAT used an analogue alarming system to detect video freeze frame and blackout from down linked video signal.
The operator needed to file a lot of paperwork for all problems manually.
The existing TS analyser only helped them to do simple troubleshooting, but all the work was done offline.
"They were really in need of an online monitoring system and analyser, and the DVStation platforms are able to fully support CBSAT requirements".
"The DVStation can help the operator to record any problems from TS and RF parameters in 24/7, and they can use the measurement logs feature to keep a long term logging to evaluate the stability of the system", concludes Lau.
"We are very happy with the Pixelmetrix solution", says Wei Sun, Technical Director, Joint System (Beijing Co).
"This system has made our lives a lot easier because it helps us increase our programs alarm system and it provides the best quality services to our customers without any interruption", adds Zushou Wang, Operation Dept Manager and Chief Engineer with CBSAT.
