Problems solved by technology

The current live broadcast system for the consumer market and its encoding and decoding methods cannot well meet the needs of telemedicine.
In the transmission and conversion format, there are many factors such as poor definition, incompatibility, and easy attenuation, which make the image and video quality become blurred and jittery after the signal is transmitted over a long distance, which greatly affects the use.
Especially when transmitting in harsh communication environments such as wireless networks, the picture is often stuck or blurred due to packet loss and other reasons, which cannot reach the level required for telemedicine

Description

technical field [0001] The invention relates to the technical field of video image transmission for telemedicine, in particular to a medical video signal acquisition and transcoding system. Background technique [0002] In China, the application of various video capture cards, hard disk video recorders and other video capture devices has greatly improved the efficiency of telemedicine. Many medical R&D teams lose no time in seeking various technical means. In order to achieve high-efficiency transmission of various medical signals such as medical images and videos, the compatibility and high efficiency of various video acquisition devices have therefore become the focus of attention. [0003] In practical applications, we will find that the video output formats of various medical devices are varied, and conventional video capture devices tend to be more non-standard formats. When faced with a wide variety of medical equipment of different brands in the hospital, the previo...
