Title:
MATRIX SWITCH INTEGRATED WITH 4K HIGH DEFINITION HDMI MATRIX SWITCHING TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2019/237422
Kind Code:
A1
Abstract:
The present invention provides a matrix switch integrated with a 4K high definition HDMI matrix switching technology, comprising a matrix switch. The matrix switch is connected to a power supply by means of a power adapter. The matrix switch comprises a control module, a switching module, HDCP decryption modules, HDCP encryption modules, an IR control module, HDMI input interfaces, HDMI output interfaces and SPDIF audio output interfaces. The switching module, the IR control module, the HDCP decryption modules and the HDCP encryption modules are connected to the control module, and the HDCP encryption modules and the HDCP decryption modules are connected to the switching module. The HDCP decryption modules are connected to a signal source device by means of the HDMI input interfaces. The HDCP encryption modules are connected to a display by means of the HDMI output interfaces. The HDCP encryption modules are connected to an audio device by means of the SPDIF audio output interfaces. The number of the HDCP decryption modules, the HDCP encryption modules, the HDMI input interfaces, the HDMI output interfaces and the SPDIF audio output interfaces each is eight. The control mode is flexibly diverse, and the use is more convenient, thereby breaking through the limitation of single signal source picture display and audio playing in a conventional conference system.
