Provided are method and device for inverse quantization and inverse transformation and non-transitory computer-readable storage medium. The method includes: performing inverse quantization processing on input data; determining whether secondary inverse transform processing is necessary; performing, in response to determining that the secondary inverse transform processing is necessary, the secondary inverse transform processing on data obtained through the inverse quantization processing, first one-dimensional inverse transform control processing on data obtained through the secondary inverse transform processing, and second one-dimensional inverse transform control processing on data obtained through the first one-dimensional inverse transform control processing; and performing, in response to determining that the secondary inverse transform processing is unnecessary, first one-dimensional inverse transform control processing on the data obtained through the inverse quantization processing, and second one-dimensional inverse transform control processing on the data obtained through the first one-dimensional inverse transform control processing.

Method and device for inverse quantization and inverse transformation and non-transitory computer-readable storage medium

A virtual reality display method, device, apparatus and storage medium are provided. The method includes: acquiring multimedia data to be displayed and a visible region of a viewer on a curved display surface, wherein the visible region is obtained by projecting a visible range of the viewer to the curved display surface, and is not larger than a display area of the curved display surface; determining target curvatures of at least two positions in the visible region of the viewer, wherein in the target curvatures, target curvatures of different positions are related to a distance to a center of the visible region of the viewer; adjusting, based on the target curvatures of the at least two positions in the visible region, a curvature of a corresponding position on the curved display surface; and mapping the multimedia data to be displayed to the curved display surface having the adjusted curvature.
