Composite Image Region Mapping for Multimedia Playback Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image display methods for multimedia resources are inefficient, requiring the retrieval and display of multiple images at different playback time points, leading to high input/output demands between clients and servers.
Innovation Solution
An image display method that determines a target region in a pre-split image corresponding to a specific playback time point, allowing for the display of a single image to represent multiple playback time points, thereby reducing the need for multiple image retrievals and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple images at different playback time points are retrieved and displayed separately, then complete coverage of playback moments is achieved, but image display efficiency deteriorates and server load increases
Solution Approach 1:
The patent combines multiple images corresponding to different playback time points into a single composite image. This composite image is then displayed in response to a user operation on the playback progress bar, eliminating the need to retrieve and display multiple separate images while maintaining complete coverage of the specified playback moments.
Solution Approach 2:
The system performs preliminary action by pre-generating and storing a composite image that contains all necessary visual information for multiple playback time points. When a user interacts with the playback progress bar, the system can immediately display the relevant portion of the pre-prepared composite image without needing to retrieve or process multiple separate images at that moment.
2Loss of information
If multiple images are retrieved for different playback time points, then all playback moments are represented, but the number of image requests and processing increases
Solution Approach 1:
Multiple images containing playback content information are merged into a single composite image structure. This reduces the number of image requests from multiple separate retrievals to a single retrieval operation, while the composite image maintains all necessary playback moment information through its internal structure.
Solution Approach 2:
The composite image is segmented into multiple regions, where each region corresponds to a specific playback time point. This segmentation allows the system to retrieve one composite image while still providing access to information for multiple playback moments, reducing retrieval complexity while preserving complete playback content information.
3Measurement precision
If separate images are displayed for each playback time point, then precise time point representation is achieved, but user interaction efficiency deteriorates
Solution Approach 1:
The system merges multiple time-point-specific images into a single composite image that can be displayed in response to a single user operation on the playback progress bar. This maintains precise time point representation through the composite image's internal structure while improving user interaction efficiency by requiring only one interaction instead of multiple separate operations.

AI summary
This application discloses an image display method performed at a terminal device. While playing a multimedia resource and after detecting that a target operation is performed on a playback progress bar of the multimedia resource, the terminal device obtains a target playback time point at which a target operation is to be performed on the playback progress bar in the multimedia resource. The terminal device determines a target region corresponding to the target playback time point in a target image, the target image comprising a plurality of regions, each region having a correspondence with a respective one of a plurality of playback time points of the multimedia resource, and displays a portion of the target image corresponding to the target region adjacent the playback progress bar. This application resolves the technical problem of relatively low image display efficiency in related art.
