Display Device Audio Mode Switching for Surround Sound Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face disturbances from unwanted surround sound effects while watching videos, as existing display devices do not provide a method to selectively enable surround sound based on user preferences or content type.
Innovation Solution
A display device with a controller that determines the audio mode based on video genre, channel number, and user settings, allowing for surround sound only when desired, using a configuration that includes a display, audio output interface, wireless communication interface, and storage to manage surround environment information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surround sound mode is always enabled, then sound quality and realism are improved, but user experience deteriorates due to unwanted surround effects during certain content types
Solution Approach 1:
The audio mode is dynamically switched between surround and non-surround based on video genre detection. The controller automatically adjusts the audio output configuration according to the detected content type, enabling surround mode for movies/concert videos and disabling it for news/lectures, thus optimizing both sound quality and user experience for different scenarios
Solution Approach 2:
The system changes audio parameters (surround effect application) based on video genre classification. By detecting the video genre and corresponding channel number, the controller modifies the audio output parameters to apply or remove surround effects, resolving the contradiction between consistent high sound quality and situationally appropriate audio presentation
2Reliability
If surround sound is provided for all video types, then audio realism is enhanced, but clarity of voice is reduced for content requiring clear audio
Solution Approach 1:
The surround effect is selectively applied only to specific video genres where it enhances realism (movies, concert videos) while being excluded from genres requiring voice clarity (news, lectures). This localized application of audio processing ensures that each content type receives the appropriate audio treatment
Solution Approach 2:
The audio processing parameters are changed based on video genre detection. For news and lecture content, the system disables surround effects to maintain voice clarity, while for movies and entertainment content, surround effects are enabled to enhance audio realism
3Adaptability or versatility
If audio mode is manually adjusted for each video, then user preferences are satisfied, but system complexity and user burden increase
Solution Approach 1:
The system automatically detects video genre and channel number, then autonomously selects the appropriate audio mode without requiring manual user input. The controller performs genre classification and automatically configures the audio output, allowing the system to serve itself in making audio decisions
Solution Approach 2:
The system uses feedback from video metadata (genre information and channel number) to automatically adjust audio mode. By continuously monitoring the content being played and responding with appropriate audio configuration changes, the system adapts to user needs without adding operational complexity

AI summary
Disclosed herein is a display device for more appropriately providing a surround effect. The display device may include a display configured to display a video, an audio output interface configured to output sound, a wireless communication interface configured to establish Bluetooth connection with at least one external speaker, and a controller configured to control an audio mode to a surround mode or a non-surround mode according to the video.
