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 limited 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...

The invention discloses a wired screen sharing device with a wireless router. The device comprises a main control unit, and also comprises a wired network interface, a network receiver, a power interface, a storage unit, a video output interface, an audio output interface and a wireless transmission unit, wherein the wired network interface receives network transmission data, and the received network data is transmitted to the main control unit via the network receiver and sent to a WiFi module after being converted by the main control unit. By using the technical scheme provided by the invention, the defect that the wireless WiFi emitted by the traditional screen sharing device cannot be connected with the Internet is improved. The wired screen sharing device can emit the wireless WiFi and provide network for wireless terminals such as a mobile phone and a tablet computer, and can also receive video and audio data of the wireless terminals such as the mobile phone and the tablet computer to be displayed on the display, and the device is widely applied to the fields of business conference, teaching and home entertainment.
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 were always cables connected. With the increase of consumer audio-visual equipment in the home, there were more and more cables in the home, and the wiring was 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 ...
