Video Information Pushing via Key Frame Feature Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback systems lack an efficient method to push relevant information to users in real-time, resulting in low accuracy and instantaneity, which affects user experience.
Innovation Solution
A method and system that acquire a key frame of a currently-played video, extract characteristic values from the key frame, and use these values to retrieve and display corresponding pushing information during video playback, enhancing relevance and immediacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If preset information is pushed before each video playback, then information can be provided to users, but the accuracy and relevance of the pushed information to the actual video content is low
Solution Approach 1:
The system extracts characteristic values from video key frames in advance and matches them with information database entries before playback. This preliminary matching ensures that when information is pushed during playback, it is highly relevant to the actual video content being displayed, resolving the contradiction between providing information and ensuring its accuracy and relevance.
Solution Approach 2:
The system changes from using static preset information to using dynamic characteristic values extracted from actual video frames. By transforming the information matching basis from predetermined text to visual feature parameters (color histograms, edge distributions, etc.), the system achieves high-accuracy matching between pushed information and actual video content.
2Speed
If information is pushed using traditional methods, then some information can be provided, but the instantaneity and real-time relevance of the pushed information is poor
Solution Approach 1:
The system continuously extracts characteristic values from current video frames and compares them with the information database in real-time during playback. This feedback mechanism ensures that the pushed information always corresponds to the current video content being displayed, achieving both instantaneity and real-time relevance without lag or mismatch.
Solution Approach 2:
The information matching and pushing process runs continuously throughout the video playback, with characteristic values being extracted from each key frame and matched against the database without interruption. This continuous operation ensures that information is always up-to-date and relevant to the current playback state, eliminating delays and maintaining real-time accuracy.

AI summary
An information pushing method and apparatus, and a terminal and server are provided. The method includes: acquiring a key frame of a currently-played video; acquiring an characteristic value of the key frame according to picture information of the key frame; acquiring, according to the characteristic value of the key frame, pushing information corresponding to the characteristic value; and displaying the pushing information in a process of playing the currently-played video. After the key frame of the currently-played video is acquired, the characteristic value of the key frame is acquired according to the picture information of the key frame, and the pushing information corresponding to the characteristic value is acquired according to the characteristic value of the key frame, so as to display the pushing information in the process of playing the currently-played video.
