Abstract: An event processing apparatus has a central processing unit (CPU) and an event queue that temporarily accumulates a plurality of events when occurring. The CPU executes an event queue optimization module for executing filtering processes to delete one or more events based on optimization definition information, and/or for executing chunking processes to integrate a plurality of events into an event, for a plurality of events accumulated in the event queue, based on a CPU load calculation involving the sum of mean CPU-execution-times for unexecuted tasks corresponding to the queued events.

Abstract: When generating animation content as summary content for a digital broadcast program, the timing for switching of animation images for display is controlled appropriately. Subtitle character string extraction means for extracting a subtitle character string from subtitle data contained in digital broadcast signals, still image extraction means for extracting one still image corresponding to the subtitle character string, and summary content generation means for generating summary content to display the extracted subtitle character strings together with the corresponding extracted still images, are provided; the summary content generation means decides the timing for switching display of the plurality of subtitle character strings and still images comprised by the summary content, based on the subtitle character strings.
