Abstract

本发明特别涉及一种提升视频分辨率和视频质量的方法、视频编码器及显示终端的解码器。为了解决现有自动计算技术中不能对视频数据做有针对性的处理，从而导致处理后的视频不能达到预期的效果，影响用户体验的问题。本发明提供一种提升视频分辨率和质量的方法，包括：计算并确定视频处理算法信息及视频处理算法信息对应的参数信息；编码视频数据、所述视频处理算法信息及视频处理算法对应的参数信息；发送编码后的视频数据、视频处理算法信息、及视频处理算法对应的参数信息至显示终端的解码器。所述视频处理算法信息对应的参数信息为视频辅助数据,包括视频滤波器类型参数和/或滤波器窗口大小参数,和/或用于分割视频的物体和/或场景的深度图视频数据，用于处理视频流程。本发明提供的提升视频质量的方法由视频编码器确定和编码视频处理算法信息及视频处理算法对应的参数信息,由显示终端的解码器根据视频处理算法信息调用相应的视频处理算法处理视频数据，能够对视频数据做有针对性的处理。通过对视频数据特性的分析，确定视频处理算法对应的参数信息，能使视频处理更具有针对性，从而使处理后的视频质量更佳，提升了用户的体验效果。
