Multimedia Playback Apparatus Automatic User Status Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia playback systems require manual user intervention to switch between 2D and 3D video or audio settings, failing to provide an optimal viewing or listening experience as they do not automatically adjust playback based on user preferences or status.
Innovation Solution
A method and apparatus that automatically adjust multimedia content playback by detecting user status, such as face angle or location, to dynamically select and display appropriate video or audio streams, ensuring an enhanced viewing or listening experience without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user control is used for 2D/3D video playback and audio playback settings, then the system structure remains simple, but the user experience is not optimized and requires continuous user intervention
Solution Approach 1:
The system automatically detects user status (face angle, location) and adjusts playback settings (2D/3D switching, audio channels) without user intervention. The detection block monitors user position and the playback block automatically configures the optimal viewing/listening mode, making the system self-adjusting based on real-time user status.
Solution Approach 2:
The system establishes a feedback loop where the detection block continuously monitors user status and feeds this information to the playback block, which then adjusts playback settings accordingly. This closed-loop control enables automatic optimization of multimedia playback based on detected user position and orientation.
2Adaptability or versatility
If automatic detection and adjustment of playback settings is implemented, then user experience is enhanced, but the device complexity increases due to additional detection and control blocks
Solution Approach 1:
The playback block serves multiple functions: it not only plays back multimedia content but also automatically adjusts 2D/3D video settings and audio playback configurations based on detection results. This multi-functionality reduces the need for separate control mechanisms while enhancing adaptability.
Solution Approach 2:
The detection block acts as an intermediary between the user and the playback system. It captures user status information and translates it into control signals for the playback block, enabling automatic adjustment without direct user interaction with playback settings.
3Productivity
If real-time detection and adjustment of playback settings is performed, then the viewing and listening experience is optimized, but the processing time and system resources increase
Solution Approach 1:
The detection block continuously monitors user status without interruption during playback. This continuous detection ensures that the system can immediately respond to any changes in user position or orientation, maintaining optimal playback settings throughout the multimedia content without requiring periodic re-adjustments.

AI summary
A playback method of a multimedia content includes: receiving the multimedia content; performing playback upon the multimedia content; detecting a user status and accordingly generating a detection result; and automatically adjusting the playback of the multimedia content in response to the detection result. A playback apparatus of a multimedia content includes a receiving block, a playback block, and a detecting block. The receiving block is used for receiving the multimedia content. The playback block is coupled to the receiving block, and used for performing playback upon the multimedia content. The detecting block is coupled to the playback block, and used for detecting a user status and accordingly generating a detection result. The playback block automatically adjusts the playback of the multimedia content in response to the detection result.
