The foundation of Jiangsu Grand Theatre was laid in 2012, and the main structure was completed in 2015. It is currently the largest cultural project in Jiangsu Province. Recently, Dalian Kodi's high-definition multi format hybrid matrix and SDI matrix have been settled in Jiangsu Grand Theatre, successfully completing the construction of its video conferencing system for various venues such as variety shows and music halls.

Dalian Kedi Kd-MF series high-definition multi format mixed matrix adopts FPGA array based pure hardware technology architecture: due to the lack of hard disk, maintenance free, and no operating system, it avoids the problems of industrial control system crashes, hardware conflicts, blue screens, and computer virus intrusion; Moreover, the startup speed is fast (<20 seconds), stable and reliable, and unexpected power outages will not cause equipment damage. It can be operated frequently to switch on and off. The input and output boards adopt a modular rear panel structure, which can flexibly configure different signal formats and quantities; The power and control boards adopt a modular front panel structure with dual power and dual control redundant hot backup, which improves the stability of the equipment. This matrix also supports hot swapping, which allows online upgrades, maintenance, and expansion to be completed by simply replacing or adding cards without power outage or changing wiring. The integration of signal interface and signal board solves the process bottlenecks that affect signal quality, such as virtual soldering and missed soldering, and reduces the number of fault points in the matrix. The design of air-cooled noise reduction temperature control greatly improves the stability of the equipment.

The Kodi Digital High Definition Matrix Series includes 3G-SDI Digital High Definition Matrix, HD-SDI Digital High Definition Matrix, and SD-SDI Digital Standard Definition Matrix, which comply with SMPTE and ITU standards. The SDI Matrix is compatible with serial digital signals of different bit rates such as 143Mbps~2.97Gbps. The automatic cable equalization function compensates for amplitude loss caused by long transmission distances from the video signal source to the matrix input. This series of matrices can adapt to uninterrupted working conditions of 7 × 24 hours, with an average time between failures exceeding 30000 hours, providing a stable and reliable signal transmission switching center for the system.

With the advent of the digital intelligence era, the development of the big data era has become full of vitality, and the informationization construction of various industries continues to develop, with a rapid increase in information volume. Correspondingly, the scale of signal control, transmission, and processing also increases with the increase of signal source access, which leads to the increasing workload of single switches and traditional matrices. How to reasonably allocate system load, meet the real-time processing needs of large capacity centralized information, and improve the overall stability of the system has become a new challenge of the times. For over a decade, Dalian Kedi has always focused on the real needs of the market and users, continuously improving China's own national brand, and striving to bring higher quality products and services to our customers with greater enthusiasm and confidence.
