About us

Since its inception, the company has always focused on digital television, professional audiovisual, and other professional audio and video signal processing software and hardware equipment and system integration research and development, manufacturing and sales. Through long-term, sustained R & D investment and independent innovation, relying on digital signal processing technology, analog signal processing technology and digital-analog hybrid processing technology, the company has gradually developed a digital TV (front-end equipment and wireless transmission equipment), professional audiovisual, application products, "3 + N" business layout, products covering encoding and transcoding, multiplexing, modulation, coding and modulation, coding and video signal processing software and hardware integration equipment and system integration. The products cover more than ten kinds of product series and hundreds of product models such as coding and transcoding, multiplexing, modulation, coding and modulation, multiplexing and modulation, demodulation and scrambling decoding, terrestrial digital TV broadcasting transmitter, stereo FM broadcasting transmitter, solid-state power source, low-level RF front-end, IPTV management software, intelligent release terminal series, etc., and the business system of multilevel products and system integration, which has become the minority of the domestic products with complete product line layout, We have become one of the few enterprises in China that have a complete product line layout and mastered the mainstream digital TV transmission standards.



We have been adhering to the concept of "independent research and development, dare to be the first, and continuous innovation", and cultivated a R & D team with high executive force and high innovation, in this team full of vitality, the vast majority of the members graduated from domestic and foreign universities in communications, software, electronics and other key national disciplines, the company has built up a senior, middle-
