Recently, Beijing Gehua Cable TV Network Co., Ltd. purchased the Dalian Kedi Kd-7021 series emergency system to upgrade and transform its broadcasting and television program receiving, transmitting, and other systems. It has been accepted and put into use.

The Dalian Kedi Kd7021 series ASI/TS stream signal monitoring emergency switch is specifically designed for stream signal monitoring, alarm, and automatic emergency switching in the front-end of digital cable TV networks. The main and backup channels, as well as the cushion broadcast signals, form a stable and reliable system of either 2 out of 1 or 3 out of 1. If the emergency switch detects a fault in the main channel's stream signal, it can directly switch the corresponding faulty channel to the backup channel. The Kd7021 digital ASI/TS stream signal emergency switch is currently a specialized emergency equipment in China that can effectively and in real-time solve the problem of secure broadcasting of wired front-end signals.

Dalian Kedi has been engaged in the production, research and development, and sales of video signal switching, transmission, and processing products for more than ten years. It enjoys high brand awareness and reputation in the broadcasting and television industry, and its products are widely used in major provincial, municipal, and county-level television stations across the country. As a well-known matrix expert in the industry, Dalian Kedi will not stop moving forward, and its products will continue to innovate, providing customers with more safe and stable products and solutions.
