Abstract

The invention wireless video transmitter and relevant data process method relates to a video signal transmission device and relevant data process method. The core of the wireless video transmitter is a video processor with a universal data storage, which stores image data received by a Wi-Fi wireless network adapter; a read-only storage, which stores video data de-compression processes and interpretation procedures of all press-key functions; a high-speed buffer storage, which stores intermediate data during the course of the video data process; a key pad comprising a plurality of function press-keys; a Wi-Fi wireless network adapter and antenna, which receives high-resolution video image data that a portable PC picks up in an identical period and passes compression process through the Wi-Fi wireless mode transmission; and a video output adapter, which is connected with a projector or a large-screen display device. The invention resolves the problems that, when portable PCs are necessary to transmit high-resolution video image data to a projector or a large-screen display device through cable wires, a lot of trouble might be caused in connection and disconnection of the cable wires.

Description

technical field [0001] The invention relates to a video signal transmission device connected with a projector or a large-screen display device through a cable, and connected with a portable computer through Wi-Fi wireless mode. Background technique [0002] In various modern venues and large classrooms, in order to fully display the pre-prepared subject materials, the speaker often needs to use a cable to connect the laptop computer with the projector or large-screen display device; during the speech process, While operating a laptop computer, play these materials through a projector or a large-screen display device while explaining. Disconnect the cables after the presentation. The process of connecting and disconnecting cables can seriously disrupt the continuity of a meeting when multiple speakers are speaking consecutively or alternately. Many existing portable computers have the function of wireless network communication, with Wi-Fi wireless network card and antenna a...
