Stackable high-definition video matrix

Abstract

The invention provides a stackable high-definition video matrix which comprises a video input and output device, a switching device, a touch screen controlling device, a redundant power source device, an external RS232 control and LAN control device and a stacking device. The video input and output device is connected with the switching device through a cable. The touch screen controlling device and the switching device are connected with the external RS232 control and LAN control device through cables. The switching device is connected with the stacking device through a cable. The redundant power source device is connected with the external RS232 control and LAN control device through a cable. The stacking device is connected with the switching device through a cable. The high-definition video matrix is really stackable.

Description

technical field [0001] The invention relates to the field of video signal processing, in particular to a stackable high-definition video matrix. Background technique [0002] The video matrix is ​​mainly used for mutual switching between the front-end video source and the back-end display device. With the continuous development of video from analog to digital, from standard definition to high definition, the video matrix has also experienced analog matrix to digital matrix, standard definition matrix to high definition The gradual evolution process of the matrix, so far, the high-definition video matrix has gradually replaced the traditional analog SD matrix. A video matrix is ​​mainly composed of input part, output part, core switching part, control part and power supply part. [0003] Existing video matrix mainly can be divided into several kinds such as analog matrix, high-definition video matrix, hybrid matrix, mixed insertion matrix at present, and the most similar to ...

Problems solved by technology

[0004] The existing high-definition video matrix has a fixed number of input channels and output channels. Generally, there are only 4 inputs and 4 outputs, 8 inputs and 8 outputs, 16 inputs and 16 outputs, and 32 inputs and 32 outputs. , each specification is a product, although the number of input and output channels is simply doubled, but the cost is very different, especially for large-scale matrix, the cost is even higher, and with the high-definition video matrix As the number of input and output channels increases, the matrix circuit is very complicated, and its stability will decrease accordingly. Therefore, the existing high-definition video matrix will have the disadvantages of high cost and low stability, and if the scale of the matrix required on site is very large, the current Some high-definition video matrixes cannot meet the demand at all

[0005] In short, the current video matrix cannot achieve a stackable high-definition video matrix
