Display Time Zone Parsing for Audio Parameter Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses fail to guarantee playback quality of audio streams when using external audio devices due to mismatched sound effect parameters, affecting user experience.
Innovation Solution
The display apparatus detects the signal source, parses time zone information to determine current time, and adjusts sound effect parameters accordingly to match the audio device, ensuring optimal playback quality for both built-in and external audio devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sound effect parameters are matched only with built-in audio device, then playback quality through built-in device is optimized, but playback quality through external audio device deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of sound effect parameters based on the detected audio device type. The system transitions from static parameters matched only for built-in devices to dynamic parameters that adapt to different audio devices (built-in or external). The processor detects the audio device type and automatically adjusts sound effect parameters in real-time, making the system flexible and adaptable to various audio output scenarios.
Solution Approach 2:
The patent changes sound effect parameters based on the detected audio device type. When an external audio device is detected, the system modifies parameters such as volume, bass, mid-range, and treble to match the characteristics of external devices, whereas built-in devices use different optimized parameters. This parameter adaptation ensures optimal playback quality regardless of the audio device being used.
2Reliability
If sound effect parameters are optimized for built-in audio device, then playback quality through built-in device is improved, but auditory experience when using external audio device deteriorates
Solution Approach 1:
The system performs self-service by automatically detecting the audio device type and adjusting sound effect parameters without requiring manual user intervention. The processor autonomously identifies whether a built-in or external audio device is being used and applies the appropriate parameter set, ensuring consistent playback quality and eliminating the need for users to manually configure settings for different devices.
Solution Approach 2:
The system implements feedback by detecting the audio device type and using this information to adjust sound effect parameters accordingly. The detection mechanism provides feedback about the connected device, and the system responds by selecting appropriate parameters, creating a closed-loop control system that maintains optimal playback quality across different audio devices.
Data Source
AI summary
Provided in the present application are a display apparatus, and a method for displaying time zone information. The display apparatus detects a signal source of the display apparatus when the display apparatus is powered on; when the signal source is a first channel, determines whether a code stream exists in the first channel; when a code stream exists in the first channel, parses the code stream to obtain first time information; when the first time information includes first time zone information, the first UTC time and the first daylight saving time, determines a first offset time corresponding to the first time zone information, and sums the first offset time, the first UTC time and the first daylight saving time to obtain a current time.
