Abstract
A graphical instruction data processing method and apparatus, and a system are disclosed, to help reduce a quantity of transmitted graphical instruction data, and lower a requirement on bandwidth. Aspects of the disclosure provide a method for processing graphical instruction data. The method includes obtaining, by a server device in a cloud interactive system, graphical instruction data of a frame, and determining whether the frame satisfies a key frame setting condition. Further, the method includes when the frame is determined to fail to satisfy the key frame setting condition, comparing the graphical instruction data of the frame with graphical instruction data of a current key frame, to obtain differential data, and sending the differential data to user equipment in the cloud interactive system. The user equipment reconstructs the graphical instruction data of the frame according to the current key frame and the differential data.
