Abstract
The present application provides a video encoding method, decoding method and devices thereof. The video encoding device includes a video capturing unit for capturing a video image; a processing unit for performing compression encoding on a background image in the video image to obtain video compression data and for structuralizing a foreground moving object in the video image to obtain foreground object metadata; a data transmission unit for transmitting the video compression data and the foreground object metadata, wherein the foreground object metadata is data that stores video structuralized semantic information. In the case that the moving objects are large in quantity or in size, the amount of video data can be effectively reduced and the limitation of network bandwidth during transmission can be mitigated.
