Recently, Dalian Kedi's domestically launched ASI intelligent emergency switching system has successfully won the bid for the digital TV front-end redundant backup system of Nanjing Radio and Television Network Company, and has been widely applied. It has now been delivered for use.

Nanjing Radio and Television Network has a high level of technical expertise and personnel. Its cable TV front-end system has been awarded the first prize for scientific and technological innovation by the State Administration of Radio, Film and Television, with a high level of research and development technology. It has successfully completed the overall conversion of over 700000 users in the main urban area, with a conversion rate of 98%, creating the "Nanjing Speed" for digital overall conversion.

After a comprehensive investigation and strict testing, the procurement of Nanjing Radio and Television Network ultimately chose Dalian Kedi's ASI intelligent emergency switching system. The expert group highly praised its technologically advanced state discrimination technology and multi-channel PID detection technology.

Kd7021ASI Intelligent Emergency Switch is a product launched by Dalian Kedi in 2006, after a long period of research and development, testing, and the use and improvement of many users. It is the first product in China that can perform advanced detection and emergency response on ASI stream signals. It has technology leading status discrimination technology and multi-channel PID detection technology, and can monitor input ASI signals in real time. It can detect and alarm signal interruptions and synchronous byte losses in real time. At the same time, it can analyze multiple PID values in ASI signals and detect specified single or multiple PID values. It is worth mentioning that it has detection function for both main and backup dual signals. When the signal is abnormal, it can be automatically or manually switched to the backup signal. When the fault signal is normal, the system will automatically switch back to its original state to ensure the system's fault free broadcast.

The Kd7021ASI intelligent emergency switch not only breaks the dependence of similar products on imports, but also surpasses imported products, pioneering the technology of simultaneous detection of main and backup channels and multi-channel PID detection, further establishing Dalian Kedi's leading position as a "matrix expert" in the field of signal switching processing in China.
