Embodiment 1

[0031] figure 1 It shows the implementation process of the method for locating the opening / ending position provided by Embodiment 1 of the present invention. Through this process, the acquisition of the opening position can be realized. The specific principle is: in a TV series, when the opening song is played, a What episode is the current TV series. In order to let the audience see clearly which episode is currently playing, the screen background when the episode number appears is relatively simple, that is, the image complexity of the video frame when the episode number appears will be relatively low. Combined with this feature of the TV series, you can Analyze the title position of the TV series, as follows:

[0032] In step S101, a frame of video is decoded, and the complexity of the frame of video is calculated. Specifically, the gray value statistics (ie, histogram) of the frame of video is calculated, and then the complexity of the image is judged according to the dis...

Embodiment 2

[0039] figure 2 It shows the implementation flow of the method for locating the opening / ending position provided by Embodiment 2 of the present invention, through which the position of the opening can be obtained. The specific principle is: in a TV series, when the opening song is played, a What episode is the current TV series. In order to allow the audience to see clearly which episode is currently playing, the screen background when the episode number appears is relatively simple, that is, the image complexity of the video frame when the episode number appears will be relatively low, and it will stay longer on the screen. For a long time, combined with these two characteristics of TV dramas, we can analyze the title position of TV dramas, as follows:

[0040] In step S201, one frame of video is decoded, and the complexity of the frame of video is calculated.

[0041] In this embodiment, a frame of video is decoded by a decoder, and the complexity of the frame of video is...

Embodiment 3

[0051] image 3 It shows the implementation flow of the method for locating the opening and closing positions provided by Embodiment 3 of the present invention, through which the position of the ending can be obtained. The video stays for a certain period of time, and then there is the ending song. Therefore, the judgment of the ending can be judged by analyzing the duration of the ending time frame, and analyzing the ending position of the TV series. The details are as follows:

[0052]In step S301, the frame rate of the local video is obtained.

[0053] In this embodiment, the frame rate information of the local video is obtained through the decoder, and the frame rate information can be used as a basis for obtaining the number of video frames within the preset duration in the subsequent step S302.

[0054] In step S302, the number of video frames within a preset period of time is calculated according to the frame rate.

[0055] In this specific embodiment, it can generall...

Abstract

The invention is applicable to the technical field of a video and provides a title / tail leader position positioning method and device as well as a television. The title / tail leader position positioning method comprises the following steps of: decoding one frame video of a local video, and calculating the complexity of the frame video; and if the complexity of the frame video is less than a pre-set complexity threshold value, using a position of the frame video as a title position of the local video. With the adoption of the title / tail leader position positioning method and device provided by the invention, title and tail leader positions can be automatically obtained from the local video without manual setting. Compared with the prior art, the user experience effect is greatly enhanced.

Description

technical field [0001] The invention belongs to the field of video technology, and in particular relates to a method and device for locating the position of the beginning / end of a film and a television. Background technique [0002] With the development of TV technology, smart TV has become the mainstream trend of TV development, and watching TV series on smart TV will also become a trend. [0003] However, when watching TV dramas, there are often very long titles and endings that are not what the audience wants to see. If you want to manually skip these titles and endings, you need to operate the remote control many times. Compared with operating on a computer, It will be even more inconvenient on TV. [0004] Judging from the current actual situation, when playing local TV dramas, smart TVs rarely have the function of automatically skipping the opening and ending credits. [0005] When playing local TV dramas, the jumping of the beginning and the end of the movie is usua...
