Video Player Information Prompting via Key Frame Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video players are limited to only playing videos, resulting in low playing effectiveness and limited functionality.
Innovation Solution
An information processing method that determines a key frame in a target video, acquires prompt information of a prompt object, and displays it in an information prompt area within the player's playing area, enhancing the player's functionality by adding a prompt function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional video player is used for solving playing problems, then the player can output video and audio, but the playing effectiveness is low because it is only used for playing videos
Solution Approach 1:
The player is transformed from a single-function video playback device into a multi-functional information processing system. By integrating the information processing unit that can identify prompt objects, extract prompt information, and display prompts in designated areas, the player now serves both video playback and information presentation functions, thereby improving playing effectiveness while expanding versatility
2Productivity
If the player is extended to add prompt function, then the information output efficiency is improved, but the device complexity increases
Solution Approach 1:
The information processing unit is integrated within the player's existing architecture, merging video playback processing and information processing functions into a unified system. This combination approach allows the player to handle both video data and prompt information through a single integrated processing pathway, improving information output efficiency while minimizing the increase in device complexity
Solution Approach 2:
A display management module acts as an intermediary between the information processing unit and the display device. This intermediary coordinates the rendering of both video content and prompt information, managing the interaction between different functional components without requiring complex direct connections between all elements, thus improving efficiency while controlling structural complexity

AI summary
Embodiments of the invention provides an information processing method and apparatus, a device, a medium and a product. The method comprises: determining a key frame in a target video corresponding to a player; obtaining target prompt information of a prompt object in the key frame; based on a playing area of the player, determining an information prompt area of the prompt object; and when the player plays the target video to the key frame, displaying the target prompt information in the information prompt area. Thus, the problem of a player only having one function is solved.
