Index generation method, index generation apparatus, index addition system, and program and storage medium thereof
First Claim
1. An index generation method comprising the steps of:
- defining, in advance, basic index information concerning an index that constitutes data that describes contents including a set of triggering actions; and
generating said index by employing operating procedures that use said basic index information, wherein information relative to a triggering action for the generation of an index and information concerning a timespan for said index are defined for said basic index information wherein said basic index information defines information concerning a hierarchy of at least one higher triggering action related to a lower triggering action such that said lower triggering action comes within said higher triggering action for a single triggering index that is formed for a single lower triggering action, and wherein a higher index covering said higher triggering action is added when the lower index covering said lower triggering action is added.

Abstract
An index generator that generates an index, which is data description contents, such as video contents, comprises: an index description device, for defining in advance basic index information concerning an index; a video display device for the input, the display or the output of contents to which an index is to be added; a triggering action input device, for accepting a triggering action in the contents that is displayed or output; and an index determination device, for generating index data based on the basic index information, which is defined by the index description device, and triggering action input history information, which is entered by the triggering action input device.

3. An index generation method that uses at least one triggering action to trigger the index generation of an index which is data concerning contents, comprising the steps of:
- selecting at least one triggering action from among a set of multiple triggering actions that are defined in advance;
determining an index effective time range for said selected triggering action, based on a first timespan extending from the occurrence of a triggering action to an index start and a second timespan extending from the occurrence of a triggering action to an index end, said timespans being defined in advance;
generating an index corresponding to said triggering action based on said effective time range; andcalculating a weight value from an algebraic formula containing said first timespan, said second timespan and a weight constant. - View Dependent Claims (4, 13, 14)
