Digital Device Picture-in-Picture Video Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital TV systems do not allow users to independently control or separate video elements within a web page, requiring users to complete watching a video before switching to a different web page, which limits user interaction and convenience.
Innovation Solution
A digital device and method that enables users to select and separate video elements from a web page, allowing them to be reproduced in a picture-in-picture window while navigating to different web pages, and simultaneously control other services and content unrelated to the web service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users view a video clip on a web page through the web browser in digital TV, then the video can be played, but users cannot change to a different web page while the video is playing and must complete or terminate viewing the video first
Solution Approach 1:
The patent segments the video element from the web page by creating a separate picture-in-picture window. The video is extracted from its original web page context and placed in an independent floating window, allowing the web page to be changed while the video continues to play in the segmented PIP window. This resolves the contradiction by enabling both video playback and web page navigation simultaneously.
Solution Approach 2:
The patent introduces a new spatial dimension by creating a picture-in-picture window that overlays the main screen. The video is moved from the two-dimensional web page plane to a separate layered dimension, allowing users to navigate web pages in the background while the video plays in the foreground PIP window, thus eliminating the need to wait for video completion before switching pages.
2Adaptability or versatility
If users want to control video elements separately from the web page, then independent control is achieved, but the system complexity increases
Solution Approach 1:
The patent extracts the video element from the web page structure and places it in a separate picture-in-picture window. This extraction allows independent control of the video player from the web page, enabling users to pause, stop, or switch videos without affecting the web page state. The extraction principle achieves independent control capability while managing system complexity through modular design.
Solution Approach 2:
The patent introduces a mediator component that handles the separation between web page elements and video playback. The mediator manages the PIP window creation, video element extraction, and control signal routing, allowing independent video control without directly complicating the core web browsing system. This intermediary layer abstracts the complexity while providing versatile control capabilities.
3Productivity
If the video is separated from the web page and reproduced in a PIP window, then users can navigate to different web pages simultaneously, but the processing and control mechanisms become more complex
Solution Approach 1:
The patent segments the video playback function from the web page rendering function by creating a separate PIP window. This segmentation allows the system to process web page navigation and video playback independently, improving user productivity by enabling simultaneous multitasking. The segmentation approach manages complexity through modular processing of separate functions.
Solution Approach 2:
The patent creates a copy of the video element in the PIP window while maintaining the original video source. This copying mechanism allows the video to be reproduced in the separate window without requiring complete duplication of processing resources, as the PIP window references the same video stream. This approach improves productivity by enabling simultaneous web page navigation while managing complexity through efficient resource sharing.
