The direction of the company's research and development on digital video transmission system for wireless technologies, products and services. Wireless Digital Video Transmission System's core technology - TDS-OFDM is a terrestrial digital TV modulation technology, invented and made by Tsinghua University in China and the United States patent. It is filled with a PN sequence of time-domain synchronous orthogonal frequency division multiplexing multi-carrier modulation method. This advanced technology organically original signal in time domain and frequency domain synchronization transmission combined payload transmitted in the frequency domain, time domain transmission control signal by spread spectrum technology for synchronization, channel estimation, fast code words capture and sound synchronization tracking performance. It invented the PN sequence spread spectrum technology based on high-protection technology and clever use of synchronous transmission OFDM guard interval filling technology; invented a new TDS-OFDM channel estimation technology to improve mobile reception performance of the system; invented a new correction wrong codec (FEC) technology, access to U.S. and European standards than better BER performance. Currently TDS-OFDM transmission protocol has become the national terrestrial digital TV transmission standard GB20600-2006 core, the standard was August 1, 2007 onwards mandatory. All systems and products company based TDS-OFDM technology.
