ABSTRACT:
A television electronic program guide intelligent memory management system and method automatically deletes the least valuable stored program information at that moment as free memory space is needed by the system. In advance of a program schedule update, the system executes a two-level memory "housekeeping" operation in which the system first scans the memory to identify obsolete schedule information. If, after this sweep, there is insufficient memory available for the next update, the system performs a second-level memory "triage" operation wherein schedule information is automatically prioritized in accordance with pre-defined rules for assessing the current value of the information to each viewer based on program air time, channel and other variables relating to program utility. The system then deletes schedule information in ascending order of value, starting with the least valuable information, and continues until enough space is available in memory to store the schedule update.
