Abstract

The present invention relates to a content generation device and a content reproduction device using situation information and device information. Content is generated by reflecting the situation information and the device information at the time of generating content and is then stored. Therefore, it is possible to receive recommendation of content suitable to a situation of a content user who wants content, thereby providing the content user with better optimum content to the situation of the content user.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a content generating apparatus and a content reproducing apparatus using context information and device information,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to content creation and playback, and more particularly, to a content generation apparatus and a content playback apparatus using context information and device information.

It is becoming increasingly difficult to accurately grasp users' potential needs in an information surplus era, in which supply is more demanding than information demand, and to find the content desired by the user. Since the number of multimedia contents such as video, music, and books is rapidly increasing and there is a great difference in preference according to user's preference, it is necessary to recommend contents specialized for user preference.

In the related art, the multimedia contents recommendation service can perform tag search using an information retrieval technology such as natural language processing, analyze user preference through CBR (Content Based Recommendation) and CF (Collaborative Filtering) And provides a predetermined content list in a manner that recommends contents having similar preferences as those of the contents.

This has the advantage that the user recommends the content for the field of interest, but it has a disadvantage that it is difficult to access new contents or content that is not suitable for the user's taste. In particular, multimedia contents that can be handled at the time when multimedia contents are generated are difficult to capture because of their location, weather, and time. This is disadvantageous in that it is unilaterally provided by the contents providing service without reflecting the situation information or device information of the user at the time of generation of the contents.

In Korean Patent Laid-Open No. 10-2009-0072575 (2009.07.02), according to the result of speculation using the user profile, the user's situation information, and the inter-user social network analysis information, And suggests techniques for recommending optimal contents. The present inventor has been studying a technique for generating and reproducing contents by reflecting the context information and device information of a content creation time or a content retrieval request time based on the prior art.
