Seamless Video Output Unit Switching with Playback Progress Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with projection functions cannot switch video output units, leading to inconvenient video playback and inability to perform other operations while content is projected.
Innovation Solution
An information processing method that detects the switch from one video output unit to another, records playback progress, and adjusts playback accordingly, allowing seamless switching between display and projection units while maintaining continuous video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is played back by both display screen and projection unit simultaneously, then video playback is achieved, but video output unit switching cannot be implemented
Solution Approach 1:
The system records the playback progress at the moment of switching detection. Before the switch occurs, the current playback position is captured and stored. This preliminary action ensures that when switching happens, the playback can resume from the correct position without interruption or duplication, resolving the contradiction between enabling output switching and maintaining playback reliability.
Solution Approach 2:
The patent implements continuous video playback by using the recorded playback progress to resume playback on the new output unit. Instead of stopping or duplicating content, the system maintains continuous playback flow across different output units, ensuring that the useful action of video playback continues uninterrupted during the switching process.
2Adaptability or versatility
If content is projected by projection unit, then projection function is achieved, but other operations cannot be implemented on display screen
Solution Approach 1:
The system segments the video playback function from the display screen function. The projection unit handles video content projection while the display screen is freed for other operations. This segmentation is achieved through independent control of playback progress recording and resumption, allowing the display screen to be used for different purposes while maintaining video playback capability on the projection unit.
3Ease of operation
If video playback progress is recorded and adjusted during switching, then seamless switching is achieved, but playback progress management complexity increases
Solution Approach 1:
The system uses the playback progress itself to manage the switching process. The recorded playback progress automatically determines the resumption point when switching occurs, eliminating the need for complex external control mechanisms. The playback system serves itself by using its own progress data to handle switching, reducing overall system complexity while achieving smooth transitions.

AI summary
The present application discloses an information processing method and an electronic device. The method comprises: detecting whether a current video output unit is switched to a second video output unit different from a first video output unit at a first time to acquire a first detection result when first video content is played back by the first video output unit; recording a first playback progress of the first video content at the first time and acquiring a second playback progress based on the first playback progress when the first detection result is yes, wherein the first playback progress and the second playback progress satisfy a preset condition; and playing back, by the second video output unit, the first video content from the second playback progress. With the above method according to the present disclosure, the technical problem in the related art that video output units cannot be switched is solved, and the technical effects of playing back a video by one output unit are achieved.
