Multimedia Playback Switching via Pre-configured Candidate Starting Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia playback systems lack flexibility and efficiency in switching between multimedia data, often requiring users to manually navigate to interested content, leading to unnecessary playback of uninteresting frames and inefficient resource usage.
Innovation Solution
A method for multimedia playback that allows switching between multimedia frames based on pre-configured candidate starting points, determined by user preferences and hot spot information, enabling automatic selection of frames that align with user interests during playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual navigation is used to switch between multimedia data, then users can select content of interest, but playback efficiency decreases due to unnecessary playback of uninteresting frames
Solution Approach 1:
The system pre-generates keyframe images at multiple candidate starting points within the second multimedia data before playback occurs. When switching is needed, the system can immediately display one of these pre-generated keyframes without having to decode and process full frames from scratch, thereby improving switching efficiency and reducing unnecessary playback of uninteresting content.
Solution Approach 2:
The system dynamically determines the target starting point for switching based on user behavior patterns, playback progress, and content analysis. Instead of fixed or manual selection, the system adaptively selects which candidate starting point to jump to, making the switching process both efficient and user-relevant without requiring manual navigation.
2Loss of energy
If full multimedia frames are played during switching, then complete content is displayed, but resource consumption increases due to processing of uninteresting frames
Solution Approach 1:
The system extracts and processes only keyframe images at candidate starting points rather than processing complete multimedia frames. This extraction approach reduces the amount of data that needs to be decoded and rendered, significantly lowering computational resource consumption during switching operations while still providing meaningful content previews.
Solution Approach 2:
Keyframe images are pre-generated and stored at multiple candidate starting points before switching occurs. This preliminary processing allows the system to quickly display relevant content without performing full frame decoding during the switching moment, thereby reducing real-time resource consumption while maintaining content quality.
3Adaptability or versatility
If switching to candidate starting points is implemented, then playback flexibility improves, but system complexity increases due to multiple starting points management
Solution Approach 1:
The second multimedia data is segmented into multiple sections with predefined candidate starting points. Each candidate starting point represents a potential jump location within the content. This segmentation allows the system to offer flexible switching options without managing the entire multimedia data as a single complex unit, making the switching mechanism more manageable and scalable.

AI summary
A multimedia playback method includes: playing first multimedia data, switching from playing the first multimedia data to playing a multimedia frame corresponding to a target starting point of second multimedia data, based on a media switching operation, the second multimedia data including multimedia frames corresponding to a plurality of time points, the plurality of time points including pre-configured P candidate starting points, and the target starting point belonging to the P candidate starting points, and switching, during the playing of the second multimedia data, from playing a first multimedia frame in the second multimedia data to playing a new multimedia frame corresponding to a new starting point, based on a target triggering operation, the first multimedia frame being a multimedia frame played at a moment at which the target triggering operation is performed, and the new starting point being a candidate starting point other than the target starting point. .
