Coding and transmission method and system based on low-frequency new video

The invention discloses a coding and transmission method and system based on a low-frequency new video, and the method comprises the steps: collecting an original image, and converting the original image into an RGB format; the original image converted into the RGB format is coded and compressed through a low-frequency coding unit, and refreshing recognition of a low-refreshing image is achieved; and the video transmission unit is used for sending and receiving the coded and compressed original image, the low-frequency decoding unit is used for decoding the coded and compressed original image, and the high-brush video echo unit is used for restoring image information. The invention provides a low-refresh-rate video transmission system for a mobile scene in the fields of medical treatment and the like, which can effectively reduce the image transmission bandwidth and improve the availability of a network under the condition of keeping the video viewing effect of a receiving end unchanged. 本发明公开了基于低频新视频的编码及传输方法
