DETAILED DESCRIPTION OF THE INVENTION

To make the object, technical scheme and advantages of the present invention clearer, examples of the present invention will be described in further detail.

FIG. 1 shows the method for locating video clips according to an example of the present invention. As shown in FIG. 1, the method for locating video clips comprises the following steps.

Block 11, receiving target dialogue to be found in a video from a user.

When the user wants to found a video clip corresponding to a certain dialogue in a video, the user can input this dialogue through a user interface. In this example of the present invention, the dialogue that the user wants to find is called a target dialogue. The device for locating video clips receives a target dialogue input by a user through a user interface.

Block 12, according to a preset matching rule, determining the subtitle data that matches the target dialogue.

In this block, the device for locating video clips can search for the subtitle data matching the target dialogue in the subtitle file corresponding to this video. In the subtitle file, a piece of subtitle data comprises at least subtitle content and a point corresponding to this subtitle content, namely the time at which this subtitle content is showed.

The device for locating video clips compares the target dialogue with subtitle content in each piece of subtitle data according to the preset matching rule, searches the subtitle content matching the target dialogue, and directly determines that subtitle data which the matching subtitle content belongs is the subtitle data matching the target dialogue.

In this example of the present invention, a subtitle file can be a plug-in subtitle file or be a readable embedded subtitle, such as an embedded subtitle in a MKV file. Therefore, examples of the present invention can be implemented to locate video chips whose corresponding subtitle file can be searched.

Therein, the preset matching rule can be an exact match rule, or a fuzzy match rule, or a close match rule. In practical applications, in order to find subtitle data corresponding to the target dialogue, except the above mentioned existing matching algorithms, other algorithms for subtitle comparing and matching can also be adopted, which is not limited by examples of the present invention.

In practical application, in order to make sure that the matched subtitle data corresponds to the dialogue the user wishes to find, the device for locating video clips can show the found subtitle data to the user, such as show subtitle content and time point of a piece of subtitle data to the user, or only show subtitle content to the user. The user can select and confirm via a user interface. After receiving the user's acknowledgement message, the device for locating video clips then determines the subtitle data corresponding to the target dialogue according to the subtitle data or subtitle content which the user chooses.

Especially, when there are multiple pieces of subtitle data matching the preset matching rule, the user can preview the multiple pieces of subtitle data first, and chooses a desirable piece of subtitle data thereof. Then, the device for locating video clips can well satisfy the user's request, and finds out the video clip the user wishes to see.

Block 13, according to the matched subtitle data, locating the video clip corresponding to the target dialogue in the video.

Because the subtitle data comprise time points corresponding to subtitle content, in this block, the time point from the matched subtitle data is first obtained, and then the video clip corresponding to the target dialogue according to the time point is located.

In this example of the present invention, the device for locating video clips may further start playing the video from the video clip. To make the user have a better video seeing experience, the device for locating video clips may start playing the video several seconds in advance of the video clip.

In the above example, the subtitle data is loaded in advance. If the subtitle of a video is not loaded when a user input a target dialogue, the device for locating video clips according to the example of the present invention may further search locally and/or the network to find and load the subtitle data.

The method for locating video clips will be described in detail taking a movie for example. FIG. 2 shows the method for locating video clips according to another example of the present invention. As shown in FIG. 2, the method for locating video clips comprises the following steps.

Block 201, receiving target dialogue that a user wants to find in a movie.

In this block, it is assumed that the movie the user is to search is “A Chinese Odyssey”. The user inputs a target dialogue showing in this movie through the user interface. This target dialogue can be a word or a phrase, or a segment of words. While inputting a target dialogue, the user can also choose a language type for the target dialogue, so as to find a subtitle. FIG. 3 is a diagram illustrating the user interface according to the present example. The target dialogue the user inputs via the user interface shown in FIG. 3 is “love”.

Block 202, judging whether the subtitle data has been loaded. If the subtitle data has been loaded, proceeds to block 207, if the subtitle data has not been loaded yet, proceeds to block 203.

Usually, the subtitle data is stored in a subtitle file. In this block, the process can be as judging whether the subtitle file has been loaded.

Block 203, searching for the subtitle data corresponding to the movie locally. When the subtitle data corresponding to the movie is found locally, proceeds to block 206. If the subtitle data corresponding to the movie can not be found locally, proceeds to block 204.

Similarly, in this block, it is also feasible to directly search for the subtitle file corresponding to the movie locally.

Block 204, searching for the subtitle data corresponding to the movie on the Internet.

In this block, the device for locating video clips can search on the network, such as Internet or local area network, to find subtitle data or subtitle file corresponding to the movie. Subtitle files that can be found on the network include subtitle files for online use. When the subtitle data corresponding to the movie are found on the network, proceeds to block 206, when the subtitle data corresponding to the movie are not found on the network, proceeds to block 205.

In practical applications, it is feasible to execute block 203 or block 204 only, which does not affect applying this embodiment of the present invention.

Block 205, prompting the user that video locating cannot be performed.

The device for locating video clips can prompt the user through a prompt box. By now, the current process is ended.

Block 206, loading the found subtitle data.
