—— Overview of the programme

Many industries will hold various exhibitions regularly. The enterprises participating in the exhibition will publicize their enterprises on the exhibition platform, so that more consumers can know their companies, their products and their culture. In order to attract customers'attention, many enterprises will choose the media advertising high-definition electronic screen (such as high-definition liquid crystal display, projector, etc.) mobile broadcast form, which has proved to be very good. Digital HDMI matrix plays an important role in this.

—— Principle of HDMI Digital Matrix

By switching the HDMI matrix, the multi-channel HD video signal source can be switched arbitrarily to the multi-channel display screen. Field staff can easily switch which display and what content through remote control. For example, one way monitor plays the company's corporate culture, another way monitor plays the product introduction...

—— Programme objectives

Through HDMI matrix, the pre-prepared video can be randomly played on multiple monitors at the exhibition site, and the output port can be controlled according to the needs of the exhibition site to achieve the effect of mobile playback. It can also transmit audio signal synchronously with external audio.

—— Equipment Selection

First of all, depending on the area of the exhibition booth, the number of display devices should be determined according to the need. This is the number of output ports of the final HDMI matrix. The input port is the number of input signal sources. There are many types of Niwell HDMI matrix, such as 8 in 8 out HDMI matrix, 16 in 16 out HDMI matrix, 32 in 32 out HDMI matrix and so on. The latter two are card-inserting chassis and fixed chassis, which have the same function, but the difference is that the latter two are more extensible (can be selected according to need).
