With the acceleration of digitalization of domestic cable TV, the problem of signal security transmission in digital front-end has become increasingly important. The signal emergency system of receivers and multiplexers generally adopts 1+1 or N+1 backup, and further adopts 2x1 emergency for main signals. Dalian Kedi has launched an intelligent TS stream/ASI 2x1 automatic switch, which is an essential product of front-end systems and has been widely applied in multiple cable networks.

The Kd6800 2x1 switch mainly has two major functions: detection and emergency automatic switching

1. Automatically detect signal interruptions, loss of synchronization bytes, and specified PID values

2. When the detection signal fails, it can be manually or automatically switched

When the system is powered off, the main circuit is connected directly and the signal is uninterrupted.

4. System balancing and clock recovery are optional to ensure signal transmission quality.

Once launched, the Dalian Kodi Digital 2x1 Intelligent Switch has been recognized and adopted by various cable TV network companies in Guangdong, Hangzhou, Nanjing, and other regions, truly achieving "safe broadcasting and preparedness", further establishing the industry leading position of "Dalian Kodi, Matrix Expert".
