The embodiment of the invention discloses a data processing method, a data processing device and terminal equipment. The method comprises the steps of extracting material attribute information of first material in a video image currently played by first equipment, wherein the video image comprises an original video image and the first material drawn on the original video image by using a computer drawing mode; generating a transmission flow according to the original video image and the material attribute information; and sending the transmission flow to the at least one second equipment. The transmission flow to be transmitted carries the material attribute information of the first material, so that when the transmission flow is displayed at the other end, the first material in the video frame image is determined via the material attribute information, so that corresponding treatment and drawing are performed, and the pressure of the other end for displaying the video image is effectively relieved.
