EPG Controller Conflict Detection for Fast Schedule Loading

The patent extracts and identifies only the specific program information that has schedule conflicts from the complete EPG page data, rather than processing all program information. The controller compares target program information with the schedule list to extract only those programs that require schedule identifiers, significantly reducing the processing scope while maintaining identification completeness.

The patent segments the EPG page processing into distinct components: program information extraction, conflict detection, and identifier display. By dividing the processing task into these segments, the system can efficiently handle only the relevant portions (programs with conflicts) separately from the rest of the EPG data, improving overall processing speed.

The patent applies local quality by displaying schedule identifiers only at the specific locations where schedule conflicts exist, rather than uniformly processing all program information. The controller determines the specific channel and time period of conflicts and generates identifiers only for those localized areas, maintaining accuracy where needed while reducing overall computational complexity.

The patent performs partial action by processing only the necessary portion of program information - specifically, only those programs that have schedule conflicts with the schedule list. This partial processing approach maintains the accuracy of schedule information for conflicting programs while avoiding the excessive computational load of processing all EPG page data.
