Video Tag Overlay Control for Seamless Information Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback systems lack user control over displaying tags associated with items in videos, limiting user interaction and information access during playback.
Innovation Solution
A user control mechanism, such as a remote control, allows users to selectively display tags by switching between play modes, with tags providing information about visible items in the video, and can be activated or deactivated with a single button press, enabling users to pause the video for tag display or view tags in alternate modes like slow-forward play.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If tags are displayed during video playback, then user access to item information is improved, but video playback continuity is disrupted
Solution Approach 1:
The system dynamically adjusts playback state based on user interaction. When a user selects a tag, the video automatically pauses to display detailed information, then resumes upon user input. This dynamic state change resolves the contradiction by making the playback continuity adaptive rather than fixed, allowing information access without permanent disruption to viewing flow.
Solution Approach 2:
The tag information display operates as a periodic interruption rather than a continuous overlay. Tags are displayed briefly at relevant moments during playback, then the video continues. This periodic action allows information to be conveyed without permanently breaking the playback continuity, resolving the contradiction between information access and viewing flow.
2Device complexity
If multiple control functions are combined in a single button, then device complexity is reduced, but control precision is degraded
Solution Approach 1:
A single remote control button is assigned multiple functions: toggling tag display, pausing/resuming video, and accessing information modes. This multi-functionality reduces the number of physical buttons and controls needed, simplifying the remote control structure while maintaining all necessary control capabilities through contextual function switching.
Solution Approach 2:
The button's function changes dynamically based on the current system state. When tags are hidden, the button activates tag display; when tags are visible, it hides them; when video is playing, it pauses; when paused, it resumes. This dynamic function assignment allows one button to replace multiple dedicated controls, reducing device complexity while preserving control precision through state-aware operation.

AI summary
A method, apparatus, and computer-readable medium display a video with a set of tags selectively overlaid on the video. The method causes a display device to display a sequence of video frames. The video depicts a plurality of visually perceptible items, and the video frames as displayed do not include any tags, thereby depicting the video in a tagless mode. The method also receives a signal requesting that the video be displayed in a tag mode. In response to receipt of said signal, the method overlays one or more visually perceptible tags on the video frames at specified positions, thereby causing the display device to display the video in a tag mode. Each of the overlaid tags is associated with at least one respective visually perceptible item appearing in the video.
