  • Patent number: 6681298
    Abstract: The present invention is directed towards a cache management system for a set top box that improves the loading speed of hypertext markup language (HTML) documents that are provided by web servers. The cache management system includes a set top box with a processor and memory that includes cache, where a plurality of HTML documents is stored in the cache. A cache manager manages the cache and calculates a removal factor for each of the HTML documents. The cache manager removes at least one of the HTML documents based on its removal factor until sufficient room is available for an additional HTML document. Additionally, the cache manager keeps the maximum number of relevant web pages in cache to maximize loading speed.
