Problems solved by technology
[0003] 1. It is inconvenient to wire two network cables, and if there is no professional network cable testing tool, it is easy to confuse the ports if the network cable is too long; 2. There is no EDID (Extended Display Identification Data) editing and management function, based on At present, the bandwidth problem of the HDMI amplifier chip on the market cannot meet the requirements of the signal bandwidth of the back-end 1080P, 36Bit or 4K×2K; 3. The infrared transmission channel needs to use one or two of the 4 twisted pairs. One data cable, which also uses the network data cable, resulting in the need for two network cables; 4. The cost of double network cables is higher than that of a single network cable

Embodiment Construction
[0065] The present invention provides an HDMI extender transmitting terminal, receiving terminal and extender transmission system, which realizes the transmission of uncompressed HDMI signals through a single network cable CET5E or CAT6, and includes the transmission of IR signals without using new integration Digital video technology HD BASE-T, on the basis of cost savings, is easy to install with a single network cable. Compared with the dual network cable technology, the installation difficulty is greatly reduced, and the cost of materials is also reduced, making the user experience better.
[0066] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention...

The invention discloses an HDMI extender emitting terminal, an HDMI extender receiving terminal and an extender transmission system. The emitting terminal comprises an HDMI connector module, a first HDMI processing module, an HDMI output drive module and a first RJ45 network interface. The HDMI connector module, the first HDMI processing module, the HDMI output drive module and the first RJ45 network interface are sequentially connected. An HDMI signal outputted by a high-definition signal playing resource is received by the HDMI connector module, processed and decoded through the first HDMI processing module, then coupled through the HDMI output drive module, and then outputted to the receiving terminal through the first RJ45 network interface, the effect of transmitting the HDMI signal through a single network cable is achieved, and a great progress is made in the field.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an HDMI extender transmitting terminal, a receiving terminal and an extender transmission system. Background technique [0002] Currently on the market, most HDMI (High Definition Multimedia Interface, high-definition multimedia interface) extenders use dual network cables to transmit uncompressed HDMI signals. When transmitting 1080P, 60Hz, 24bit high-definition data, the maximum transmission distance is 50 meters. However, the method of transmitting data with two network cables will have the following disadvantages: [0003] 1. It is inconvenient to wire two network cables, and if there is no professional network cable testing tool, it is easy to confuse the ports if the network cable is too long; 2. There is no EDID (Extended Display Identification Data) editing and management function, based on At present, the bandwidth problem of the HDMI amplifier chip on the ...
