Since its launch in the market, the KD-7200 series digital switching matrix has received high praise, providing strong support for the high-quality and high-definition broadcasting system of television stations. Today, Dalian Kedi has implemented a targeted digital transformation solution for the broadcasting system of the political and legal channel's studio based on the needs of Changsha Radio and Television Station and the actual situation of the existing equipment on the station: the KD-7200 series digital switching matrix based on SDI signals.

Due to the expansion of its business scope, Changsha Radio and Television Station now needs to add a digital hard disk broadcasting system for two channels. Dalian Kedi, relying on leading technology in the radio and television industry and past practical experience, proposes a signal switching based on SDI digital matrix, and uses a hard disk server combined with SDI peripheral equipment to solve the broadcasting system for political and legal channels in the studio.

The equipment for Dalian Kedi Broadcasting System in this solution includes 2 SDI signal matrices with equalization function in Kd7200-0808E, 8 SDI signal 1/8 modules with equalization and clock recovery in KD-6800 series HDA-6801R, 2 SDI signal embedding modules with frame synchronization function in MUX-6802, 2 SDI signal de embedding modules with DMX-6802, 2 SDI signal de embedding modules with analog monitoring function in DMA-6802, and 2 SDI signal label keying all-in-one machines with LDC6800HD-LK, 4 ECO-HD-2 dual SDI signal automatic switchers, and BG-40 synchronization signals. Generator.

Compared with traditional solutions, Dalian Kedi Broadcasting System is based on SDI signals, switching signals through SDI digital matrix, and using a hard disk server combined with SDI dual channel time base signal broadcasting switcher to broadcast the front-end solution, eliminating signal loss caused by signal A/D conversion. In addition, the KD-7200 series digital switching matrix adopts a dual channel digital time base design, achieving arbitrary switching of program broadcasting signals without jitter or flicker, ensuring that the switching screen is as complete as possible in an instant. The adaptive cable balancing function can automatically perform cable balancing on input serial digital signals, extend the transmission distance from the signal source to the matrix, effectively solve the transmission problem of digital signals, and also have the function of power-off direct connection and power-off memory. The entire system adopts the form of primary and backup switching, which greatly improves the stability and reliability of the broadcasting system while optimizing the system and reducing costs. Even if one channel fails, the other channel can still broadcast in a timely manner, making the operation of the entire system safer.

The Dalian Kedi KD-7200 series digital switching matrix has always been widely used by provincial and municipal television stations nationwide due to its strong technological advantages. At the same time, Dalian Kedi adheres to the values and purposes of focus, innovation, integrity, development, and harmony, and is committed to providing customers with innovative products, services, and solutions that meet their needs, providing customers with a more perfect broadcasting system.
