TV Source-Switch Volume Control Using Per-Input History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when changing content sources on TVs, as different content sources provide varying volume levels, requiring separate volume adjustments despite the same TV volume setting.
Innovation Solution
An electronic apparatus and method that stores volume histories for multiple content sources, allowing the processor to identify and adjust the volume level based on the volume histories of the current and changed content sources, updating the volume history accordingly, and displaying the adjusted volume level on a user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the TV volume level is kept the same when changing content sources, then the TV volume setting is maintained, but different volumes are provided according to the content source causing inconvenience to the user
Solution Approach 1:
The system automatically identifies and adjusts the volume level when switching content sources without requiring user intervention. The processor retrieves volume histories for both the current and new content sources, calculates the appropriate volume adjustment, and applies it automatically, allowing the system to serve itself rather than requiring manual user adjustment.
Solution Approach 2:
The system uses stored volume histories as feedback to determine appropriate volume levels. By continuously recording and referencing past volume settings for different content sources, the system learns from previous adjustments and applies this feedback to automatically set optimal volumes when switching sources, creating a closed-loop adaptive system.
2Measurement precision
If separate volume control is required for each content source, then accurate volume adjustment is achieved, but user convenience deteriorates due to repeated manual adjustments
Solution Approach 1:
The system performs preliminary actions by storing volume histories for multiple content sources in advance. When a content source changes, the processor quickly retrieves the pre-stored volume history data and immediately applies the appropriate volume adjustment, eliminating the need for users to manually adjust volume each time and reducing the time loss associated with repeated adjustments.
3Extent of automation
If volume history is stored for multiple content sources, then automatic volume identification is enabled, but device complexity increases due to additional data storage and processing
Solution Approach 1:
The processor performs multiple functions using the same volume history storage mechanism. It not only stores but also retrieves, compares, calculates differences, and applies volume adjustments based on the stored histories. This multi-functional approach allows automatic volume adjustment without requiring separate dedicated components for each function, thereby managing device complexity efficiently.

AI summary
An electronic apparatus is provided. The electronic apparatus includes: a memory configured to store volume histories for a plurality of content sources; and a processor configured to, based on a content source for providing a content being changed from a first content source to a second content source, among the plurality of content sources, identify a volume level corresponding to the second content source based on a volume history of the first content source and a volume history of the second content source among the stored volume histories, and change a currently-set volume level to the identified volume level, and update the volume history of the second content source based on the changed volume level.
