METHOD AND APPARATUS FOR META-DATA STORAGE AND RETRIEVAL

摘要

Meta-data retrieved externally is determined to be relevant to the creation of an electronic programming guide (EPG) or relevant to a user's preferred programs. The meta-data is stored locally if it is determined that it is relevant to the creation of the EPG or if it is relevant to the user's preferred programs. All other meta-data is discarded. When a user requests meta-data, an attempt is made to retrieve the data from a local database, and if the attempt fails, then the meta-data is obtained from an external source.
