detailed description

In order to solve the technical problem of inaccurate correlation, the embodiment of the present invention proposes a method and device for obtaining video and a method and device for playing video. The corresponding beneficial effects that can be achieved are described in detail.

Embodiment one:

Embodiment 1 provides a method for obtaining videos, which is used for processing M videos to obtain videos related to a theme, where M is an integer greater than or equal to 1.

Referring to Figure 1, the method includes the following steps:

S101. Obtain M videos.

S102. Determine whether N videos among the M videos are related to the theme, where N is an integer less than or equal to M and greater than 0.

In the specific implementation process, the M videos include videos that are not related to the theme, and also include videos that are related to the theme. When the video is related to the theme, there may be a segment in the video that is related to the theme. There may also be multiple clips related to the topic, and when there are N videos related to the topic, then execute S103, that is, when there are N videos related to the topic, collect the N videos.

Among the collected N videos, each video has one or more segments related to the theme; or all the segments are related to the theme.

After N videos are collected, each of the N videos will be processed to obtain P videos.

Specifically, each of the P videos includes video data corresponding to a topic, and P is an integer greater than 0.

When P videos are obtained from N videos, it is obtained through a series of processing on N videos. Please refer to Figure 2 for specific processing steps, as follows:

S201. When there are N videos related to the topic, analyze the N videos by voice, and determine whether the N videos have the first key information related to the topic.

In a specific embodiment, the specific way of judging whether there is the first key information related to the theme in the N videos is as follows:

First, when there are N videos related to the topic, N videos are voice analyzed to obtain voice keywords related to the topic;

Secondly, the voice keyword is matched with the preset first key information;

Again, when the matching is successful, it is judged that the N videos have the first key information related to the topic.

S202. Analyzing the text in the N videos, and judging whether the N videos contain the second key information related to the theme.

In a specific embodiment, it is judged whether there is the second key information related to the theme in the N videos, the specific method is:

First, when there are N videos related to the topic, analyze N videos by text to obtain text keywords related to the topic;

Secondly, matching the text keyword with the preset first key information;

Again, when the matching is successful, it is judged that the N videos contain the second key information related to the theme.

S203, when R videos in the N videos have the first key information related to the topic and/or the second key information related to the topic, then process the N videos to obtain R videos, where R is positive integer.

S204. Synthesize R videos into P videos.

After P videos are obtained, the P videos are processed to obtain Q videos, wherein Q is a positive integer smaller than P.

Each of the Q videos has an original video, and the Q videos can be associated with the original videos corresponding to the Q videos.

The function of association is that after the user watches one of the Q videos, if he needs to watch the original video containing the video, he can link to the original video containing the video by starting the video, such as clicking on the video , the original video will start playing.

In practical applications, for example, the user needs to watch a video about Zhang San wearing a dragon robe to participate in an international film festival. The video is 1 minute long, and this video is included in an entertainment video. In addition to the content of the International Film Festival, other entertainment videos will also be reported, such as another report about Zhang San and other entertainment stars participating in the International Film Festival.

In addition to reporting the entertainment video, many videos on TV channels or the Internet also include other types of news videos such as financial videos and comprehensive videos, and the comprehensive video also has corresponding reports about Zhang San wearing a dragon robe to participate in the International Film Festival.

When 3 videos are obtained, the 3 videos are: financial video, entertainment video, and comprehensive video. Among the three videos, some are related to Zhang San's participation in the international film festival, such as entertainment videos and comprehensive videos; some are not related to Zhang San's participation in the international film festival, such as financial videos.

After obtaining these 3 videos, determine which of these 3 videos are related to Zhang San’s participation in the International Film Festival. From the above videos, it can be concluded that there are 2 videos, namely the entertainment video and the comprehensive video, which are related to Zhang San’s participation in the film festival. If the content of the International Film Festival is relevant, these 2 videos will be collected.

Each of these two videos has a segment related to the content of Zhang San wearing a dragon robe to participate in the International Film Festival.

When these 2 videos are collected, voice analysis is performed on these 2 videos to determine whether there is the first key information related to Zhang San wearing a dragon robe to participate in the International Film Festival in these 2 videos.

Take an entertainment video as an example:

When playing an entertainment video, if the three keywords "Zhang San", "Dragon Robe" and "International Film Festival" appear in the language content of the video, then these three keywords are obtained, and these three keywords are combined with The pre-set first key information is used for matching, and there are many ways of matching, such as matching in the form of scoring, matching using similarity calculation, or matching using a preset corresponding relationship.

There can be one or more preset first key information. Here, three words "Zhang San", "Dragon Robe" and "International Film Festival" are set as the first key information.

When matching in the form of scoring:

When one of the three voice keywords in the voice analysis matches the first key information, the score is 1, and two voice keywords match the first key information, and the score is 3. Each of the three voice keywords matches the first key information. Words match the first key information with 5 points, and when it reaches 3 points, it means that the entertainment video has the first key information related to the content of Zhang San wearing a dragon robe to participate in the International Film Festival.

Then, the above three voice keywords are matched with the preset first key information one by one, and the matching result is 5 points, which means that there is the first key related to the content of Zhang San wearing a dragon robe to participate in the International Film Festival in the entertainment video information.

After performing text analysis on entertainment news to obtain text keywords, the text keywords are also matched with preset second key information. The second key information may be the same as the first key information, or may not be the same.

For example, the preset second key information is "Zhang San" and "Dragon Robe".

When matching the text keyword with the preset second key information, the matching method is the same as the above method.

When one of the three text keywords in the text analysis matches the first key information, the score is 2 points, and if two text keywords match the first key information, the score is 3 points. It has the second key information related to the content of Zhang San wearing a dragon robe to participate in the International Film Festival.

Then match the above three text keywords with the preset second key information one by one, and the matching result is 3 points, which means that there is a second key related to the content of Zhang San wearing a dragon robe to participate in the International Film Festival in the entertainment video information.

When the entertainment video has the first key information and the second key information related to the content of Zhang San wearing the dragon robe to participate in the International Film Festival, then the entertainment video is processed, such as cutting information about Zhang San wearing the dragon robe to participate in the international film section of the 1 minute video to get the video.
