SYSTEM AND METHOD FOR INTERACTIVE SPATIO-TEMPORAL STREAMING DATA

摘要

System and method for providing a probabilistic order of tiles relative to a current section of a video that a user is viewing. A cache implementation uses this ordering to decide what tiles to evict from the cache, i.e. which tiles will probably not be accessed within a particular timeframe, but not when to evict (this is up to the cache implementation). A cache implementation can also use the prioritized list of the present embodiment to pre-fetch tiles.

1. A computer-based method for caching data comprising:
calculating, by a specially-programmed computer, a plurality of probabilities that a tile of the data will be accessed within a timeframe, each of the probabilities being based on navigation of the data, each of the probabilities being calculated for different portions of the data; and managing, by the specially-programmed computer, a cache based on the probabilities.
