Embodiment Construction
[0016] The embodiments of the present invention will be further described below in combination with specific embodiments and accompanying drawings.
[0017] Such as figure 1 As shown, the present invention is a wired screen sharing device with a wireless router, which includes: a main control unit 10, a wired network interface 11, a network receiver 12, a power supply interface 21, a storage unit, and a video output interface 61 , an audio output interface 71 and a wireless transmission unit. The wired network interface 11 receives the data transmitted by the network, transmits the received network data to the main control unit 10 through the network receiver 12, and sends the data to the WiFi module in the wireless transmission unit after being converted by the main control unit 10 81. The WiFi module 81 also has a WiFi antenna 82. In the present invention, the main control unit 10 adopts a CPU whose model is RK3036.
[0018] Specifically, the power interface 21 adopts a 5...

The invention discloses a wired screen sharing device with a wireless router function, which includes a main control unit, and the screen sharing device also includes a wired network interface connected to the main control unit, a network receiver, a power supply interface, a storage unit, a video output interface, audio output interface and wireless transmission unit; the wired network interface receives the data transmitted by the network, transmits the received network data to the main control unit through the network receiver, and sends the data to the main control unit after being converted by the main control unit WiFi module. After adopting the above technical solution, the present invention improves the shortcoming that the wireless WiFi sent by the traditional screen sharing device does not have the ability to connect to the Internet. The wired screen sharer can send out wireless WiFi to provide a network for wireless terminals such as mobile phones and tablets, and can also receive video and audio data from wireless terminals such as mobile phones and tablets, and display them on the display. widely used.
Description
Technical field: [0001] The invention relates to the technical field of wireless co-screening, in particular to a wired co-screening device with a router function and capable of transmitting wireless WiFi. Background technique: [0002] Traditional audio and video playback devices (ie A V Source) and display devices (ie A V Sink) are connected by wires. This connection is not an Ethernet interface. Earlier, an analog signal was transmitted through an interface such as CVBS or VGA, which caused distortion. Later, HDMI and other technologies were used to transmit digital signals, but there was always a cable connection. With the increase of household consumer audio-visual equipment, there are more and more cables in the home. The wiring is very inconvenient, unsightly, and unreliable. Later, the HDMI organization proposed the wireless HDMI standard, but it has not been realized so far. An Israeli company uses analog radio frequency technology to directly modulate audio and vid...
