Wired/wireless integrated multi-screen display endoscopic system

Medical electronic endoscope has a wide range of applications in medical diagnostic. Most of the traditional medical electronic endoscopes are wired endoscopes which are unavailable in many circumstances. Considering the weaknesses of the traditional video endoscope and combining with its future development trend, we design and implement the wired/wireless multi-screen display endoscopic system. The video signal can not only be transmitted to the Liquid Crystal Display by cable, but also be transmitted to the mobile terminals via Wi-Fi. In this work, a video endoscopic system prototype was built which uses H.264 video compression to reduce the data size needed to be transmitted by the Wi-Fi transmitter. The ARM9 based video processor performs the main task of video compression and transmission, CC3100 to establish the wireless link and the camera used is analog camera.
