HDMI high-definition signal-based IP network extension device

Abstract

The invention relates to an HDMI high-definition signal-based IP network extension device consisting of a transmitter and a receiver, wherein the transmitter comprises a liquid crystal display module,an infrared receiving module, an input / output button, an EDID configuration module, a PC control module, an infrared output port, an infrared input port, at least two HDMI input ports, a preamplifiermodule, a CAT5e / 6 type network cable input interface and a transmitter power supply module; The receiver comprises at least two HDMI output ports, an acoustic source interface, an acoustic source switching switch, an infrared receiver interface, an infrared transmitter interface, a CAT5e / 6 network cable output interface and a receiver power supply module. The receiver comprises a plurality of HDMI output ports, an acoustic source interface, an acoustic source switching switch, an infrared receiver interface, an infrared transmitter interface, a CAT5e / 6 network cable output interface and a receiver power supply module. The HDMI extender of the present invention extends the HD signal by 120 meters with a CAT 5e / 6 wire, And it can reach 1080P. It not only breaks the limit of HDMI wire transmission length, but also is more convenient and flexible. It saves the cost for customers. It is suitable for noise, transmission distance and places with limited safety, data center control, information distribution, conference room demonstration, teaching environment and company training places.

Description

technical field [0001] The present application relates to an HDMI extension device, and more particularly relates to an IP network extension device based on an HDMI high-definition signal. Background technique [0002] HDMI, High Definition Multimedia Interface (English: High Definition Multimedia Interface) is a digital video / audio interface technology that meets the standards of the high-definition era and can be used in set-top boxes, DVD players, personal computers and televisions. The HDMI 1.0 standard was officially released on December 9, 2002, and the HDMI specification version 1.4a was released on March 4, 2010. HDMI can transmit audio and video signals at the same time, and can transmit uncompressed high-definition video and multi-channel audio data with high quality. The maximum data transmission speed is 5Gbps. At the same time, there is no need for digital / analog or analog / digital conversion before signal transmission. The HDMI specification can be used with H...

Problems solved by technology

However, under normal circumstances, the transmission distance of the nearly lossless image quality of the HDMI data cable is within 15 meters, and the longest cannot exceed 30 meters. The signal loss of the cable exceeding 30 meters is serious, and the picture display effect is extremely poor.
