Embodiment Construction

[0071] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0072] In the related art, in an Electronic Program Guide (EPG, Electronic Program Guide) processing system, real-time program prediction is required. The prediction program is actually to perform video repetition detection. However, the task of manual repetitive detection is very large, the efficiency is low, and the accuracy and precision of repetitive detection are relatively low. Therefore, it is impossible to accurately predict real-time programs, which brings great inconvenience to users.

[0073] In order to solve the above technical problems, an embodiment of the present disclosure provides a method for judging repeated videos, which is applicable to a judgi...

Abstract

The invention discloses a judgment method and device of repetitive video. The method includes: obtaining several video sections to be tested from the real-time data flow; obtaining the target characteristic vector of each video section to be tested and the template characteristic vector of each template video section from all template video sections; calculating the vector distance between the target characteristic vector of each video section to be tested and the template characteristic vector of each template video section; when the vector distance between the target characteristic vector of any video section to be tested and the template characteristic vector of any template video section is smaller than or equal to the preset vector distance, at least part videos in any video section to be tested are deemed to be repetitive with any template video section. The technical scheme can be used for precise detection of video repeatability and can ensure the accuracy and efficiency of video repeatability detection; through the technical scheme, the specific starting time of the template video in the videos to be tested can be determined precisely, which can ensure precise program forecast.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a method and device for judging repeated videos. Background technique [0002] Currently, in an electronic program guide (EPG, Electronic Program Guide) processing system, real-time program prediction is required. The prediction program is actually to perform video repetition detection. However, the task of manual repetitive detection is very large, the efficiency is low, and the accuracy and precision of repetitive detection are relatively low. Therefore, it is impossible to accurately predict real-time programs, which brings great inconvenience to users. Contents of the invention [0003] The present invention provides a method and device for judging repeated videos, which are used to accurately detect video repeats using a template video, and ensure the accuracy and efficiency of video repeat detection, thereby realizing accurate program prediction. [0004] The p...
