With the approach of the Olympics, the safe broadcasting of digital cable television has become a focus of attention for the current broadcasting and television technology departments. However, the issue of real-time and effective monitoring of ASI stream signals in the front-end of digital cable TV for emergency response has not been completely resolved.

After several years of research and development and improvement, the Dalian Kedi 7021 series ASI digital signal monitoring emergency system has completely solved this problem through the use of multiple network stations.

The Kd7021 monitoring and emergency system integrates a full range of functions for monitoring, alarming, and emergency response of digital ASI/TS flow signals, including:

1. Comprehensive real-time stream monitoring:

Comprehensively parse the stream form; Can monitor signal interruptions; Monitor for loss or error of synchronization bytes, PAT, and PMT; Can monitor multiple specified PID simultaneously; And the main and backup multiple signals can be monitored simultaneously.

2. Provide various alarm methods such as sound, light, voice, etc

3. Intelligent emergency switching:

Having comprehensive judgment rules to achieve all-round multi-level switching; The automatic switching between the main and backup paths, especially the absence of black fields during switching and the direct power outage function of the system, ensures the stability and quality of the system.

4. Kd7021 can conveniently set the monitoring PID values of multiple devices and streams within the system through serial or network interfaces, and keep track of the system status at any time.

The Kd7021 monitoring emergency system has been fully applied in multiple cable TV networks in Guangdong, Nanjing, Hangzhou, Xiamen, Quanzhou, and other provinces. At the same time, it has successfully passed testing in multiple provincial and municipal networks and is ready for official use. Its innovative and unique functions and extremely high cost-effectiveness have received praise and support from numerous technical experts and leaders. We believe that the Kd7021 series products can become a strong guarantee for the safe broadcasting of digital cable TV, and contribute to the broadcasting industry and the Beijing Olympics with Kodi's strength.
