DekTec Launches World's 1st DTMB Modulator PCI Card for Chinese DTV at CCBN

At CCBN, DekTec proudly presents a low-cost PCI-Card modulator for DTMB, the new Chinese National Standard for Digital Terrestrial TV Broadcasting. DekTec has managed to provide support for this new standard in a timely fashion thanks to its local technology partner NexDigita in Shenzhen, China. The implementation supports all system parameters defined in DTMB.
