ABSTRACT:
A digital broadcast system which, during the control of caching tables multiplexed into a transport stream, optimally updates the caching without wasting filter resources on changes such as updates to a higher version, addition, or disappearance of the tables.A digital broadcast apparatus broadcasts a transport stream into which an available table information table (ATT) is multiplexed. The ATT monitoring unit in the receiving apparatus regularly monitors an update in the ATT and generates an available table information list every time the ATT has been updated to a higher version. The cache controlling unit compares the available table information list with a cache information list, assigns a filter resource and updates the cache of the table when there is a table updated to a higher version or added, and clears the cache of the table when there is a table that has disappeared.
