When it comes to the "four major families" of matrix experts, many people naturally think of the four series of products of Dalian Kedi Video Technology Co., Ltd. That's right! At CCBN2006, we will witness the new style of these "four major families"!

        The "four major families" of matrix experts include KD2000 series analog matrix switches, KD7000 series digital matrix switches, KD6000 series distribution amplifiers, and KD6800 series digital conversion distributors, covering over a thousand specifications and models of products. All the products exhibited this time are equipped with beautiful and elegant new chassis, which will be refreshing to you!

        The Kd2000 series analog matrix switcher is a high-quality analog video audio matrix switching system developed by Dalian Kedi Video Technology Co., Ltd. It adopts advanced design structure, high-quality imported electronic components, advanced technology, high integration, flexible composition, stable and reliable operation. All technical indicators have been tested by authoritative departments and meet or exceed the national standard Class A. The Kd2000 series analog matrix has 8 sub products, ranging in size from 2x1 to 256x256, covering formats such as composite video, RGB/YUV component video, computer video (RGBHV), audio mono, audio stereo, RS-422 data signals, etc. Various formats of signals can be freely configured in the same matrix switching system for switching. Suitable models can be selected in all fields and links of analog matrix switching applications, including broadcasting, production, recording, overall control scheduling, emergency, monitoring, multimedia, and education, among Kd2000 products.

The Kd7000 high-quality digital matrix developed by Dalian Kedi Video Technology Co., Ltd. utilizes advanced technology and design structure, and adopts the most advanced imported switching chips and high-quality mature electronic components from the beginning of this century to ensure the high safety, reliability, and performance indicators of the matrix system. The Kd7000 series digital matrix scales from 4x1 to 512x512, and is compatible with various signal formats such as SDI, DVB-ASI, SD, HD, etc. It can transmit digital signals at a rate of 10Mb/s to 1.5Gb/s. The equalization function and clock recovery function ensure high-quality transmission of signals. The clock recovery function of ASI signals is the first in China and fully reaches the international advanced level. The Kd7000 series digital matrix has been appraised and tested by experts, and has passed the achievement appraisal of the Ministry of Science and Technology, determining its technological status as "leading domestically and internationally". All indicators have also reached or exceeded national standards. In 2004, it was awarded the "National Science and Technology Innovation Fund", and in 2005, it was awarded the "Liaoning Province Science and Technology Innovation Fund".

At present, the Kd7000 series digital matrix has been adopted by multiple TV stations, cable TV network centers, and other departments. The first 128 × 128 ASI large digital matrix in China was produced by Dalian Kedi Company and officially put into use in Jiangyin Cable Network Company. It was applied in the main control channel, achieving two goals. Firstly, it was the first time in China that a 128 × 128 ASI digital matrix was used in the main channel; For the first time in China, we have cooperated with well-known foreign manufacturers to fully integrate with the Harley system, achieve interconnection and interoperability, and jointly build a cable TV front-end system. In addition, the 128 channel ASI digital matrix switch used by Nanjing Radio and Television Network Center has been applied in the video front-end of the network center. After more than a year of use, the system has been running stably and has received unanimous praise from users, replacing the original plan to purchase foreign products. The Kd7000 series digital matrix has become the preferred product for digital broadcasting and television in China.
