The embodiment of the invention provides a cache management method and device, and relates to the technical field of video processing. Comprising the following steps: receiving description information of the tactile media buffer and description information of buffer slices of the tactile media buffer; the tactile media buffer is used for caching a target tactile media file, and performing cache slice division on the tactile media buffer according to description information of cache slices of the tactile media buffer, the display engine determines a tactile media accessor according to the index value of the accessor index syntax element declaration in the target media reference array of the MPEG tactile media reference list of the target node description module; and accessing data in a cache slice of the tactile media cache through a tactile media accessor to obtain a tactile value of the first tactile material attribute. Some embodiments of the invention are used for obtaining the tactile value of the tactile
