Abstract
A video encoding method is provided in the present invention. The method includes: determining a range of interest ROI in an ith frame, wherein the ROI comprises at least one ROI macroblock; extracting characteristic information of the at least one ROI macroblock, wherein the characteristic information comprises location information and type information of the at least one ROI macroblock; determining a quantization parameter QP corresponding to each of the at least one ROI macroblock; encoding the characteristic information of the at least one ROI macroblock according to the determined QP corresponding to each ROI macroblock, to obtain an ROI characteristic stream of the ith frame; and adding, to a video stream of the ith frame, the QP corresponding to each ROI macroblock and the ROI characteristic stream of the ith frame, to perform sending, wherein the video stream of the ith frame is obtained by encoding the ROI and a non-ROI comprised in the ith frame.
