Video Frame Capture for Smooth Page Flip Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies face challenges in smoothly transitioning video playback with page flip animation in digital magazines due to hardware resource constraints, often resulting in video content becoming invisible during page flips, degrading the user experience.
Innovation Solution
The method involves monitoring user interactions, pausing video playback, capturing a current video frame, and disabling graphics resource usage for video rendering during page flips, allowing the captured frame to be displayed until the animation is finished, enabling seamless transition to the next page.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the graphics resource is used for rendering video playback and page flip animation simultaneously, then the user can interact with both video content and page navigation, but the video content becomes invisible during page flip due to graphics resource constraints
Solution Approach 1:
The system captures a current video frame before the page flip animation begins and prepares it for display in advance. This preliminary action ensures that when the page flip occurs, the captured frame is already ready to be displayed, preventing video invisibility during the transition.
Solution Approach 2:
The graphics resource usage is segmented into distinct time periods: before page flip (video rendering), during page flip (captured frame display), and after page flip (next page rendering). This temporal segmentation allows the graphics resource to be dedicated to one task at a time, ensuring video visibility is maintained through the captured frame during the flip animation.
2Reliability
If the graphics resource is dedicated to video rendering, then video playback is smooth, but page flip animation cannot be rendered simultaneously
Solution Approach 1:
The system employs periodic action by alternating the graphics resource between video rendering and page flip animation based on timing. During video playback periods, the graphics resource renders video frames; during page flip periods, it renders the animation. This periodic switching ensures both functions can be supported sequentially without conflict.
Solution Approach 2:
The captured video frame acts as an intermediary element that bridges the gap between video playback and page flip animation. Instead of directly switching between video rendering and page flip rendering, the system uses the captured frame as a temporary placeholder, allowing smooth transition without losing video content visibility.
3Duration of action of stationary object
If the video playback continues during page flip animation, then video content remains continuous, but the graphics resource constraint causes video to become invisible
Solution Approach 1:
The system creates a copy of the current video frame before the page flip animation. This captured frame is then displayed during the page flip instead of the original video content. The copy maintains the visual presence of video content during the transition, preventing invisibility while allowing the graphics resource to be reused for page flip rendering.

AI summary
A computer implemented method enables smooth transition of video playback with page flip action within a digital magazine. The method comprises steps of monitoring a user's interactions with a video content item displayed on a current page of the digital magazine. Upon detecting a user flipping the current page to a next page, the video content item is paused, a graphics resource used for rending the video content item is disabled and a current video frame of the video content item is captured. In response to the user flipping the current page to the next page, the graphics resource is enabled for rending the page flip action, a modified current page with portions of the next page are gradually displayed to the user, while the captured video frame is continuously displayed on the current page until the page flip action is finished.
