Program guide providing device

摘要

An electronic program guide providing device can include editor units (31 and 32) each for updating electronic program information which has already been stored in an electronic program information storage unit (11). When each of the editor units updates the electronic program information stored in the electronic program information storage unit, it notifies a table generation unit (21) of update information on the updating at the same time. The table generation unit determines which table is to be regenerated based on the update information, and regenerates only one or more tables that need to be regenerated.
