Abstract

The invention relates to a digital matrix control system for realizing multi-mode access. An HDMI (High-Definition Multimedia Interface) transmission technology is adopted to complete the internal digital transmission of the system and data transmission among cascaded matrix hosts. Compared with the prior art, the invention has the following advantages that firstly, the HDMI technology is used skillfully to transmit any formats of data signals and greatly increase transmission bandwidth; next, when multiple machine cabinets (matrix hosts) are cascaded, the transmission among the machine cabinets adopts HDMI transmission technology and optical fiber transmission technology, and the signal loss is almost zero; in addition, the system has the advantages of static resistance, large transmission distance, low cost, and the like by using the HDMI transmission; and finally, digital signals are directly processed by the system and transmitted in the system, a transmission switching process causes no signal loss.

Description

technical field [0001] The invention relates to a digital matrix control system and method for realizing multi-mode access. Background technique [0002] With the increasing perfection of the digital monitoring system, especially the overall control of the switching matrix, it has really promoted the process of digitalization and networking of the matrix system. At present, in the security monitoring industry, traditional matrix systems and small-channel digital hard disk video recorders are mainly used. If a large and medium-sized monitoring system is established to realize the combination of analog and digital, multiple sets of matrices and other equipment are required to be used in combination, and There is no signal connection port between the traditional matrix system and the digital hard disk video recorder, and each digital hard disk video recorder must be connected to the matrix system through a video distributor, and information exchange between the systems cannot b...
