Abstract
本发明公开了一种数据处理方法及装置,涉及数据处理领域,所述方法包括:第一设备检测显示缓冲区中的当前图像帧是动态显示场景下所产生的图像帧还是静态显示场景下所产生的图像帧;若当前图像帧是动态显示场景下所产生的图像帧,则根据第一编码质量对当前图像帧进行编码,第一编码质量用于指示编码后的图像帧还原为编码前的图像帧的第一还原水平;若当前图像帧是静态显示场景下所产生的图像帧,则根据第二编码质量对当前图像帧进行编码,第二编码质量用于指示编码后的图像帧还原为编码前的图像帧的第二还原水平;第二还原水平高于第一还原水平。本发明解决了动态显示场景下共享显示的实时性低的问题,达到了提高共享显示的实时性的效果。
