*4.2.3 Video compression processing mechanism*

The doctors of remote robot surgery can obtain a wider and clearer operation field through 3D laparoscopy, and how to obtain a high-resolution 3D laparoscopy image is one of the key technologies of robot remote surgery. Because the laparoscopic image is a 3D high-definition image, which requires high bandwidth and network real-time, an external high-speed data acquisition card needs to be used at the patient end for image acquisition and 3D compression processing, which can effectively reduce the image transmission time and delay. In order to ensure the continuity of the
