Abstract

An event importance adjustment device which extracts events which reflect a course of video contents, and extracts scenes which reflect the course of the video contents. The event importance adjustment device comprises a digest scenario information storing unit that manages a digest scenario information indicative of an extraction condition and an extraction order of an event. The event importance adjustment device further comprises a scenario importance adjusting unit that inputs event information with importance containing the events and situation information to extract an appropriate event.

Claims

1. An event importance adjustment device, comprising:

a digest scenario information memory device that stores and manages digest scenario information indicative of;

a) an event extraction condition,

b) an extraction order,

c) an event importance adjustment point, and

d) a scenario pattern including a plurality of video sections within a course of video contents, the video sections determined based on the video contents,

wherein a)-d) are specific to presentation of the course of the video contents;

a scenario importance adjusting processor that;

e) receives event information with importance containing events each indicative of a phenomenon in the video contents and the importance of the event as well as situation information indicative of a situation of the video contents,

f) extracts an appropriate event based on the digest scenario information, the appropriate event being extracted from a video section based on the scenario pattern, and

g) adjusts the importance of the event, the importance of the appropriate event being adjusted based on the video section from which the appropriate event was extracted,

an event correlation pattern information storing unit that manages an event correlation pattern table indicative of a trigger event which triggers start of processing, a correlation event which is associated with the trigger event, and an importance adjustment point of the correlation event; and

an event correlation importance adjusting unit that extracts an appropriate correlation event based on the event correlation pattern table if the event adjusted by the scenario importance adjusting unit is the trigger event, and adjusts the importance of the correlation event.

2. The event importance adjustment device according to claim 1,

wherein the digest scenario information includes event extraction adjustment table that sets patterns based on presence or absence of a scoring point and the transition thereof and sets an extraction order and an extraction condition of events for each of the patterns.

3. The event importance adjustment device according to claim 1,

wherein the digest scenario information includes an event extraction adjustment table that sets patterns based on presence or absence of a difference of scoring point and the transition thereof and sets an extraction order and an extraction condition of events for each of the patterns.

4. An event importance adjustment method comprising the steps of:

receiving event information with importance containing events indicative of a phenomenon in video contents, the importance of the event, situation information indicative of a situation of the video contents, and a scenario pattern including a plurality of video sections within a course of video contents, the video sections determined based on the video contents;

extracting by a processor an appropriate event based on digest scenario information stored in a memory, the appropriate event being extracted from a video section based on the scenario pattern, and adjusting the importance of the appropriate event based on the video section from which the appropriate event was extracted;

managing an event correlation pattern table indicative of a trigger event which triggers start of processing, a correlation event which is associated with the trigger event, and the importance adjustment point of the correlation event to extract an appropriate correlation event based on the event correlation pattern table if the adjusted event is the trigger event so as to adjust the importance of the correlation event.

5. A computer readable storage medium storing a program executed on a computer to perform the steps of:

receiving event information with importance containing events each indicative of a phenomenon in video contents, the importance of the event, situation information indicative of a situation of the video contents, and a scenario pattern including a plurality of video sections within a course of video contents, the video sections determined based on the video contents;

extracting an appropriate event based on digest scenario information, the appropriate event being extracted from a video section based on the scenario pattern, and adjusting the importance of the appropriate event based on the video section from which the appropriate event was extracted;

managing an event correlation pattern table indicative of a trigger event which triggers start of processing, a correlation event which is associated with the trigger event, and importance adjustment point of the correlation event to extract an appropriate correlation event based on the event correlation pattern table if the adjusted event is the trigger event so as to adjust importance of the correlation event.
