Problems solved by technology

[0015] Moreover, using the method of automatically extracting the feature information to generate opinions and opinion scores has the following problems: there are restrictions on the types or numbers of opinions and opinion scores that depend on the content of the recognition technology, and the accuracy of opinions and opinion scores depends on the accuracy of the recognition technology. performance
So the problem is that this process will take a lot of time and cost

Embodiment 1

[0050] Embodiment 1 of the present invention assumes that a metadata author will enter an opinion and an opinion score for that opinion into content in real time while monitoring the content in real time. A metadata creation device according to Embodiment 1 of the present invention will be described using a plurality of drawings. first use figure 1 The configuration of the metadata creation apparatus according to Embodiment 1 of the present invention will be described. figure 1 is a structural block diagram of the metadata creation device according to Embodiment 1 of the present invention.

[0051] exist figure 1 , the content 11 for which metadata is to be created is supplied to the metadata creation means f10. The content 11 is one or more media of moving image, voice or moving image / voice or text or stereoscopic image or animation.

[0052] Also, the metadata creating means f10 includes a content input section 101 for inputting content 11 . According to Embodiment 1, t...

Embodiment 2

[0105] The metadata creation apparatus according to Embodiment 2 allows the author to input an opinion and opinion score by continuously pressing a key of the opinion score input section 108 . That is, when a key is held down, the opinion and opinion score represented by the key is taken. When no key is pressed, the opinion and opinion score represented by the initial value (default) key is used.

[0106] For example, if Figure 9 As shown, when the "1" key is continuously pressed from time t1 to time t2, the opinion and opinion score represented by the "1" key are adopted from time t1 to time t2. For example, when using Figure 4 In the opinion score allocation table 112 shown, opinion "A" and opinion score "0.2" are used from time t1 to time t2.

[0107] Also, since no key is pressed from time t2 to time t3, the opinion and opinion score corresponding to the "3" key are taken by default. For example, when using Figure 4 In the opinion score allocation table 112 shown, op...

Embodiment 3

[0133] Such as Figure 11 As shown, the content encoding unit 1104 of the metadata creation apparatus f20 according to Embodiment 3 includes a segmenting unit 1105 for dividing the content 11 into segments of smaller time units according to the content of the content 11 . Then, the content encoding section 1104 uses the time information of the segment change point as the time information 106 . That is, the content encoding section 1104 uses the segment start time and end time as the time information 106 .

[0134] Also, when the content 11 is a moving image or moving image / sound, the segmentation method of the segmenting part 1105 segments the content by determining a division point (feature point), and designates the time corresponding to the division point as the time information 106 . Other methods can also be used as the segmentation method of the segmentation section 1105 . Figure 11 is a structural block diagram of the metadata creating device according to Embodiment...

Abstract

The present invention is intended to detect, when a meta data author inputs a viewpoint and viewpoint score to contents having time information, time information of the contents corresponding to the input time of the viewpoint and viewpoint score input, assign corresponding time information to the viewpoint and viewpoint score input and create meta data related to the viewpoint and viewpoint score.

Description

technical field [0001] The present invention relates to a device and method for creating metadata, which is used to create metadata of viewpoint and viewpoint score in real time for content with time information. Background technique [0002] A traditional approach is to create index information by extracting characteristic information of multimedia content. For extracting feature information of multimedia content, manual and automatic methods can be used. [0003] There are two methods used as automatic methods. One method is to extract feature information through a feature information extraction algorithm without depending on the meaning of the content and the quality of the multimedia content. Another method is to recognize the meaning of multimedia content and perform structuring using a recognition technology dedicated to each medium. [0004] The former is described, for example, in "On a way to Retrieve Video using Gamon Information (a method of extracting video us...
