摘要
Video coding techniques are disclosed that can accommodate low bandwidth events and preserve visual quality, at least in areas of an image that have high significance to a viewer. Region(s) of interest may be identified from content of input frame that will be coded. Two representations of the input frame may be generated at different resolutions. A low resolution representation of the input frame may be coded according to predictive coding techniques in which a portion outside the region of interest is coded at higher quality than a portion inside the region of interest. A high resolution representation of the input frame may be coded according to predictive coding techniques in which a portion inside the region of interest is coded at higher quality than a portion outside the region of interest. Doing so preserves visual quality, at least in areas of the input image that correspond to the region of interest.
