Problems solved by technology

[0006] However, in the case of non-text-based content such as video and audio as objects that provide metadata under the MPEG-7 standard, there is no such technique for automatically extracting metadata, such as for news programs The time period of the content indicates the content of the news, currently, metadata is also manually provided
[0007] Since such manual provision of metadata is an inefficient method that takes a lot of time and effort, in terms of cost, content providers cannot provide a wide variety of metadata to non-text based content
[0008] Also, since human-provided metadata is not diverse, it is impossible to retrieve other news-related video content with high accuracy

no. 1 Embodiment

[0030] FIG. 1 is a block diagram illustrating the configuration of a content management system in the first embodiment of the present invention. The content management system shown in FIG. 1 has a non-text-based content management part 110 and a text-based content management part 120 .

[0031] The non-text-based content management section 110 manages non-text-based content and content metadata such as video and audio, and it contains a non-text-based content storage section 111, a non-text metadata storage section 112, a metadata input section 113 , a request sending part 114 , and an additional metadata obtaining part 115 .

[0032] The non-text-based content storage section 111 stores non-text-based content data.

[0033] The non-text metadata storage section 112 stores metadata associated with the content stored in the non-text-based content storage section 111 .

[0034] Metadata input section 113 is for manually providing metadata to non-text based content.

no. 2 Embodiment

[0069] A second embodiment of the present invention will be described below. In addition to deleting the additional metadata acquisition part 115 and the additional metadata transmission part 126 and adding the related content attached metadata acquisition part 711, similar non-text-based content retrieval part 712, non-text related content information storage part 713, related content The content management system of this embodiment has the same configuration as the content management system in FIG. 1 except for the information generation section 721, the text-related content information storage section 722, and the related content-attached metadata transmission section 723.

[0070] The related content-attached metadata acquisition section 711 acquires the related content-attached metadata provided by the text-based content management section 120a.

[0071] A similar non-text-based content retrieval section 712 generates related content information related to non-text-based ...

Abstract

A content managing system capable of achieving the processing for assigning metadata related to the subject of multimedia content such as video and audio to the content with less effort. Non-text content managing section 110 transmits original metadata manually assigned to non-text based content to text-based content managing section 120. Similar text-based content retrieval section 125 in text-based content managing section 120 retrieves similar text-based content using the original metadata, and the metadata automatically extracted with respect to the similar text-based content is transmitted to non-text based content managing section 110 as additional metadata for the non-text based content.

Description

technical field [0001] The present invention relates to providing metadata to non-text content such as video and audio in a computer system for managing multimedia content. Background technique [0002] The ubiquity of the Internet has given us access to a wide variety of content. And, in recent years, broadband communication networks using technologies such as ADSL (Asymmetric Digital Subscriber Line) and FTTH (Fiber To The Home) provide multimedia information such as video and audio, and mainly include The environment where small text and / or image content can be used appropriately, and it is expected that more various content will be provided in the future. [0003] Therefore, as available content increases, techniques such as retrieval of desired content and filtering to eliminate useless content become more and more important. In particular, multimedia content such as video and audio is not the same as text-based content and, unless processed, cannot be targeted for se...
