The 3rd China International Audio Visual Integrated Equipment and Technology Exhibition (Infocomm2007)

The IS China exhibition moved to Beijing in 2007 and received more attention, with particularly strong popularity. Dalian Kodi, known as the "matrix expert", participated in the IS China event for the first time. With its outstanding structural and performance advantages, the entire series of matrix products received a lot of attention, and the exhibition was a fruitful harvest.

At this exhibition, Dalian Kedi showcased matrices including 128 × 128 large analog matrices, 32 RGB matrices, and multiple multi format matrices. The unique front panel structure and hot backup dual power configuration of Kodi products have won everyone's praise. Among them, the Kdv2100 synchronous switch's true jitter free and flicker free switching effect has attracted a lot of attention and is known as a highlight of this exhibition. During the exhibition, Dalian Kedi reached cooperation intentions with multiple companies, which can be said to be a fruitful return.

Modular plug-in matrix switcher makes its debut in IS CHINA 2007

The matrix switch of Dalian Kodi, which made its debut at the IS China 2007 exhibition with its modular design, plug-in structure, and dual power hot backup, has caught the attention of many experts.

There are many brands of matrix switches in the market, but there are not many brands that truly satisfy integrators. In the past, almost all matrix switchers in the market used a fixed integrated structure. This simple structure has a lower cost for small and medium-sized matrices, but it limits the flexibility of matrices, the convenience of maintenance, and the possibility of mass production of large and medium-sized matrix switchers, resulting in small matrices everywhere in the market and varying quality. The cost of large and medium-sized matrices is high and the price is astonishing, and designers often modify the original plan due to budget issues. Although some well-known foreign brands have adopted modular design plug-in structures, their prices are also high and often only used in high-end occasions.

Dalian Kedi Video Technology Co., Ltd. has been committed to the research and development of China's brand matrix, using this internationally advanced "modular design and plug-in structure". Kodi's modular design adopts a 4-16 layer PCB design, with each layer independently grounded and greatly enhanced anti-interference performance. The "plug-in structure" allows all circuit boards to be equipped with electric heating and plugging, and multiple signals can be mixed in one matrix for easy expansion and maintenance.

The most important point of module design is that when producing a matrix switch with a plug-in structure, only batch production of the switch board and chassis is required, and assembly is carried out according to customer needs. This means that producing a "128 x 128" matrix switch is not very time-consuming and difficult. The dual power hot backup structure further enhances the stability of the use of the Cody matrix.

Switching a jitter free Kdv2100 synchronous switch

With the continuous development of the AV industry, more and more people are pursuing higher quality and more perfect display environments, and flickering and shaking during image output have become unavoidable flaws. Dalian Kedi Company has introduced mature technology from the broadcasting and television industry and successfully launched the Kdv2100 synchronous switch with truly synchronized and jitter free signal output switching, completely solving the problems of flickering and jitter during switching.

The signal sources in AV systems are diverse, and the signals transmitted by different cameras, recorders, and cameras cannot be synchronized at all. The commonly used field reverse switching technology can only work under the premise of complete synchronization of all signals, and can only ensure signal switching without jitter in this ideal state. In reality, switching without jitter or flicker cannot be achieved. The Kdv2100 synchronous switcher launched by Dalian Kedi Company adopts a unique built-in dual channel time base design. As is well known, analog video images are composed of coherent frames and frames. When one frame of the two signals is completely synchronized, these two frames are also synchronized. The time base corrector is specifically used to synchronize signals. Its internal frame image automatically corrects the signal, ensuring that the two signals to be switched are completely synchronized, thereby ensuring that the signal output can be switched freely without jitter or flicker.
