It is performed in the same way as access control for general files. In other words, when the conventional access management method is applied to the content, only the management that "the entire video or audio can be accessed or not accessible" can be performed. For example, "For a video recording of the speech of the president of a certain company, most of the content is publicity of the company, so it is okay to publish it publicly, but the part related to research and development does not leak information to other companies. In the past, if you couldn't publish it, you could only select "whether or not to publish the video itself".

On the other hand, in recent years, even for contents such as video streams or video streams including video and audio, structural information is created by structuring the content, and the structural information is used to manage, edit, and utilize the video. Various methods have been developed. Specifically, as an example of structuring the content, for example, Japanese Patent No. 3208116 “recording medium recording video index information, video information management method using video index information, recording medium recording audio index information” And "audio information management method using audio index information" defines a range of an arbitrary frame in a video stream as a segment, and expresses the same range defined by one segment as a set of a plurality of segments. There has been proposed a method of creating a hierarchical structure of a video stream by defining a set of a plurality of segments as a package when possible.

Further, as a technique for structuring contents or re-editing the structure of structured contents, Japanese Patent Application Laid-Open No. 2001-125925 "Structure display method and program for causing a computer to execute the method is recorded. In a "computer-readable recording medium", a range of arbitrary frames in a video stream is defined as a segment, and the same range defined by one segment can be expressed as a set of multiple segments. By defining the set of as a package, the structure information that defines the hierarchical structure of the video stream is used to edit the structure of the video stream, and the segmentation state and length (frame range) of the structured video stream. ) Is displayed in a visually easy-to-understand manner and the video stream is displayed. Techniques for easily create structural elements such as segments or packages comprising structural information beam is disclosed.
