Abstract

An information processing system includes a device for recording data, a device for generating browsing data, a device for storing the browsing data and data in association with each other, and a device for displaying the browsing data. Corresponding data are retrieved from the displayed browsing data. When the data is non-visible such as audio data, a still image input unit or a video input device is used to create browsing data. Also, upon creation, updating or deletion of data, the browsing data are automatically created, updated or deleted respectively. When the data is AV data, browsing data is created based on the information detected by a scene change point detector and a volume detector.
