detailed description

The present application is further described below in conjunction with the accompanying drawings. It is to be understood that the examples are not intended to limit the scope of the application. In addition, it should be understood that various changes and modifications may be made by those skilled in the art after the disclosure of the present disclosure.

The smart TV of the present application can access the video resource of the cloud server through the network, the smart TV receives the search keyword of the user, and sends the search keyword to the cloud server, and the cloud server returns the search result to the smart TV after completing the search according to the search keyword. end.

Example 1

Referring to FIG. 1, the present application first provides a method for searching for video resources.

S101: Receive a first search keyword input by a user.

When the user accesses the video resource of the cloud server through the smart TV, the search interface may include a search box in the user interface, and the user may input the keyword to be searched in the search box, and when the user clicks the OK button, the smart TV searches the box. The search keywords input by the user are sent to the cloud server. The search keyword input by the user in the embodiment of the present application may be a sentence in the video.

For example, when a user accesses the video resource of the cloud server and wants to watch the movie "The World Without Thieves", the user may forget the name of the movie and only remember some of the plots in the movie. For example, the user may only remember the movie. In the line "Li Shu is very angry, the consequences are very serious", the user can search In the box, directly input "Li Shu is very angry, the consequences are very serious", when the user clicks the OK button, the smart TV sends the search keyword input by the user to the cloud server.

S102: Search for a subtitle file that matches the first search keyword from the pre-stored text subtitle file.

After receiving the search content, the cloud server searches for the subtitle file. Specifically, each video resource in the cloud server includes a subtitle file in a separate text format corresponding thereto. Subtitle files generally include graphic format subtitles as well as text format subtitles. Among them, the graphic format subtitle is composed of idx and sub file, and idx is equivalent to the index file, which includes the time code of the subtitle appearing and the attribute of the subtitle display, and the sub file is the subtitle data itself. The extension of text format subtitles is usually srt, smi, ssa or sub (same as the graphic format suffix, but the data format is different), where srt text subtitles are the most popular, because its production and modification is very simple: a time code + a sentence subtitle. For example, for the following srt subtitle file content: 4500:02:52,184-->00:02:53,617 slowly, indicating: 45th line subtitle, display time from the audio and video start 2 minutes 52.184 seconds To the second point of 53.617 seconds, the subtitles are: Take it slowly. For subtitle files in graphic format, the server converts them into subtitles in text format, such as the content of subtitle files in graphic format: 00:05:50.200-->00:05:50.210 picture 30; means: display time from audio and video The beginning of the 5th minute 50.200 seconds to the 5th minute 50.210 seconds of the subtitle content is the content of the picture 30, the cloud server can use the OCR method to text the subtitle picture, for example, the recognition result of the picture 30 is "hello", such You can convert the subtitle file in image format to a subtitle file in text format, for example 00:05:50.200-->00:05:50.210 Hello.

Specifically, each video resource in the cloud server includes a video resource corresponding thereto. Information, the piece of video resource information may include a video name, a profile, a thumbnail, a play address, a subtitle file, and the like. The resource information of all the video resources may be stored in the cloud server in the form of a list. Table 1 schematically shows the specific storage style of the resource information of the partial video resources.

Table 1

The subtitle file in text format stored in the cloud server includes text of the subtitle, corresponding time information, and the like. When receiving the user input search keyword, the related content may be searched in the subtitle file to obtain a subtitle file matching the search keyword. If the matching is successful, the video corresponding to the subtitle file may be returned, or the matching subtitle information in the subtitle file may be returned, or the progress bar of the video may be directly jumped to the time corresponding to the matched subtitle while returning the corresponding video. Point, when the user clicks to play, it starts playing directly from that point in time.

S103: Acquire resource information of a video resource corresponding to the subtitle file.

After receiving the search content sent by the smart TV, the cloud server may search for related content in the subtitle file to find whether there is a subtitle matching the search content. If the matching result is obtained, the cloud server may return the resource information of the video resource to the smart device. TV. For example, the search content received by the cloud server is "Li Shu is very angry, the consequences are very serious", the cloud server will sequentially search the text subtitle documents in the list, for example, the cloud server searches for the world without a thief. srt and "Li Shu very Angry, the consequences are very serious "matching subtitles, then the cloud server will further read other information in the list corresponding to the text subtitle file, such as further acquisition of video name, profile, thumbnail, play address, and the like.

In some cases, the user may only be interested in a part of the content in the video. For example, the user may only be interested in a video at the time point corresponding to the searched subtitle. For this reason, the cloud server may also use the subtitle in the embodiment of the present application. The matching subtitle information in the file is returned to the smart TV, and the subtitle information may include time information of the subtitle, so that the user can obtain time information related to the search content, and after obtaining the information, the user can select to view the matched subtitle when viewing the video. The corresponding time point. For example, the search content received by the cloud server is "Li Shu is very angry, the consequences are very serious", the cloud server will sequentially search the text subtitle documents in the list, for example, the cloud server searches for the world without a thief. srt and "Li Shu very Angry, the consequences are very serious "matching subtitles, in the subtitle file world without thieves. srt subtitle information of the subtitles is: 6000:63:54, 190-->00:63:54, 617 Li Shu is very angry, The consequences are very serious. In addition to returning the video resource information, the cloud server will also return the subtitle information to the smart TV, so that the user can know the time point of the video corresponding to the current search content: 00:63:54,190 -->00:63:54,617, so users can choose to go directly from fast-forward when watching 00:63:54,190 at this point in time to start watching the video.

When searching, it may search for multiple subtitle files that match the search content. At this time, the cloud server will return all the video resources corresponding to the subtitle file to the smart TV. For example, the search content input by the user is "I love you", and the cloud server searches for "I love you" in the subtitle file new policeman.srt, the world without thief.srt, and Huoyuanjia.srt, then the cloud server will The resources information of the three video resources of the new policeman, the world without thieves, and Huo Yuanjia are returned to the smart TV terminal, and the smart television terminal can display the received resource information, and the resource information can include the video name, thumbnail, profile, etc. The smart TV terminal can display the received resource information, so that the user can select the video that he needs to watch from the returned results. For example, if the user chooses to watch the world without a thief, he can directly click on the playing address of the world without thief to watch. .

Further, when searching, there may be multiple subtitles matching the search content in the same subtitle file. At this time, the cloud server may stop searching in the subtitle file after searching for a matching content, and continue searching. The next subtitle file, which can improve the efficiency of the search. For example, the search content input by the user is "I love you", and the cloud server searches for the subtitle information in the new policeman.srt of the subtitle file: 1000:2:54,170-->00:2:54,600 I love After searching for this matching subtitle, the cloud server will stop searching in the new policeman.srt and continue to search for the next subtitle file without thief.srt until all the subtitle files have been searched.

During the search process, if the matching result is greater than the threshold, that is, the subtitle file (video resource) matches the search content input by the user, the user may be prompted, for example, prompting the user to say another sentence, and merging the two contents together. Get up and search. For example, the search content entered by the user is "I love You, the cloud server finds 500 subtitle files containing the content in the subtitle file, which is greater than the threshold, for example 50. At this time, the cloud server will prompt the user, for example, the interface of the smart TV displays "excessive search results, please If another search content is input, the user can input "robbery" in the input box, and after receiving the search content, the smart TV searches for a subtitle file containing two subtitles "I love you" and "robbery", for example The search results are 30, and the cloud server returns these 30 results to the smart TV. In this way, the search results can be limited to a range acceptable to the user.

In addition to searching for matching content in the subtitle file, the cloud server can also search in the video name and profile. It is preferable to search in the subtitle file when no matching item is found in the video name or profile. For example, if the user inputs "Li Shu is very angry, the consequences are very serious", when the cloud server does not search for a match in the video name and profile, the search continues to search for the subtitle file to find a match.

S104: Send resource information to the smart TV end and display it.

The cloud server will return the obtained resource information to the smart TV. For example, returning to the smart TV, "The World Without Thieves", Wang Bo (Andy Lau) and Wang Li (Liu Ruoying) are the best thief partners, because they are pregnant. Thin child..., picture 2, http://www.xxxxxx.com/vod/play/85403.shtml , the user can play the video by clicking on the play link. In this way, the user can search for the video he wants to watch based on a line in the video.

Alternatively, the cloud server returns the subtitle information to the smart TV in addition to the video resource information, so that the user can know the time point of the video corresponding to the current search content: 00:63:54, 190--> 00:63:54,617, so users can choose to watch the video directly from 00:63:54,190 by fast-forward.

Further, when the corresponding video is returned, the progress bar of the video player is directly jumped to the time point corresponding to the matched subtitle, and when the user clicks the play button, the play starts directly from the time point. For example, for example, the cloud server has no subtitle information for the subtitles in the subtitle file. The subtitle information of the subtitle is: 60 00:63:54, 190-->00:63:54, 617 Li Shu is very angry, the consequences are very serious, then The cloud server sends the smart TV according to the play address and subtitle time of the video in the table. After receiving the play address, the smart TV will call the player to play the video, and send the subtitle time to the player, and the player receives the time information. After that, the progress bar will jump directly to the time point corresponding to the matching subtitle, for example, jump to 00:63:54, 190, when the user clicks the play button, it starts playing directly from 00:63:54,190.

Further, the user can also search for video resources by voice. Specifically, the user can turn on the voice input on the smart TV end, and the voice receiving device in the smart TV is normally turned off. When the user needs to search by voice, the voice receiving device of the smart TV can be turned on, for example, The access interface may include a voice input button, and the user may click a button to pop up a prompt box to prompt the user to input a voice, or the user may also turn on the microphone through a specific button on the remote controller, or may open the microphone through an operation menu in the smart TV. After the microphone is turned on, the smart TV starts to monitor the user's voice input. After receiving the voice command input by the user, the smart TV starts to parse the user's voice command and recognize the user's voice command. The voice recognition technology is a relatively mature technology and will not be described in detail herein. For example, if the voice command is parsed to get "Li Shu is very angry, the consequences are serious", the smart TV sends the obtained search content to the cloud server, and the cloud server searches according to the received search content and returns the search result to the smart TV.

A computer readable program on which a program for executing a search method of a video resource is recorded Recording medium. The computer readable recording medium includes any mechanism for storing or transmitting information in a form readable by a computer (eg, a computer). For example, a machine-readable medium includes read only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash storage media, electrical, optical, acoustic, or other forms of propagation signals (eg, carrier waves) , infrared signals, digital signals, etc.).
