FIELD AND METHOD FOR SEARCHING SCENE IN MEDIA, APPARATUS AND SERVER APPLIED TO THE SAME

The present invention relates to a system and method for scene retrieval in media, and to an apparatus and a server applied thereto, and more particularly, to include a media scene or at least one media scene desired by a user based on metadata in the media. Search for a media scene group (that is, a set of multiple scenes), determine a playback time for the searched media scene or media scene group, and set a playback section, and then play the set playback section. A system and method for scene retrieval in media, and apparatus and server applied thereto.

As the download speed through the Internet has become faster, users can easily transmit or receive large amounts of data through the Internet. Therefore, it is becoming common to download high-quality video data, which has not been attained before, through the Internet and replay it in real time.

In fact, most TV programs can be viewed again through the Internet, and various videos such as air / satellite TV, movies, music videos, and sports broadcasts are provided through the Internet.

Unlike a TV broadcasted according to a unilaterally arranged program, a video provided through the Internet has an advantage of playing a video of a desired content at a desired time. For example, a user who wants to watch the 9 o'clock news may search for and watch the 9 o'clock news through the Internet even the next morning.

However, if a user wants to watch a video through the Internet, the user has to search for a desired video among numerous videos provided through the Internet. That is, a user who wants to watch a TV program called "Taewangsa Singi" should find a desired program video through keyword search using the title of the program "Taewangsa Singi" or the name of the program hero "Bae Yong Joon."

Therefore, various attempts have been made to provide a video search service that can effectively search a user's desired video.

Here, the video search service includes not only searching on the web but also searching for a video stored in the terminal device or the server.

On the other hand, a user is often interested in some contents of a specific program. In other words, the user is often interested in the contents of a part of the program rather than the entire program.

For example, a user who wants to watch a soccer relay may want to watch only a scene in which a specific player scores a goal, rather than watching the entire soccer relay program. However, since a general video search method uses the entire program as the search target, it is not possible to search for some scenes and the like of the video desired by the user.

In the past, there have been attempts to search a video by using dialogue information (or subtitle information) included in the video in order to enable searching for a part of the video. In other words, the user wanted to search for a part of a specific video that has a dialogue or subtitle related to a search word input by the user, thereby searching for a part of the desired video.

However, in many cases, dialogue or subtitles alone cannot adequately reflect the content of the video. For example, if you want to find a kiss scene of a drama, because the kiss scene often has no dialogue, it is very difficult to find a scene in which drama heroes kiss only by the dialogue or subtitles. In addition, in the case of a video without dialogue or subtitles, video search using this method is not possible at all.

Accordingly, there is a demand for a method for enabling a user to search for a desired scene using media such as a video.

Accordingly, the present invention was created to solve the above problems, and an object of the present invention is to provide a media scene group including at least one media scene or a media scene desired by a user based on metadata in the media.
