Screen Recording Device Audio Restriction Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen recording technologies generate video data that includes irrelevant program and music content, necessitating complex copyright processes for redistribution, making it difficult for creators to widely disseminate their programs.
Innovation Solution
A screen recording device, method, and storage medium that include image display-outputting, user-acquired audio reproduction-outputting, video data recording, and recording restricting means to record the screen with user-acquired audio while restricting recording when the audio is being output, allowing for selective reproduction and output of audio and screen content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If screen recording is performed during audio reproduction, then the screen content can be captured, but the recorded video data contains irrelevant audio content requiring complex copyright processes
Solution Approach 1:
The invention extracts and removes the audio reproduction function from the screen recording process. When screen recording is detected, the system automatically suspends audio reproduction, thereby extracting the problematic element (audio output) that causes copyright complications while preserving the screen recording capability.
Solution Approach 2:
The system takes preliminary action by detecting the start of screen recording before it fully commences, and preemptively suspends audio reproduction. This preliminary anti-action prevents the generation of video data containing copyrighted audio content in the first place, avoiding the need for subsequent copyright processing.
2Ease of operation
If audio reproduction is allowed during screen recording, then user convenience is improved, but redistribution of recorded data becomes difficult due to copyright issues
Solution Approach 1:
The invention separates the audio reproduction function from the screen recording function by suspending audio output when recording is detected. This extraction eliminates the copyright conflict that would otherwise prevent redistribution, while the system maintains user convenience through other means such as allowing audio reproduction when recording is not active.
3Loss of information
If video data is recorded including user-acquired audio, then complete screen and audio capture is achieved, but the data requires complex copyright processing for redistribution
Solution Approach 1:
The invention extracts audio content from the recording process by suspending audio reproduction when screen recording is detected. This prevents copyrighted audio from being captured in the video data, thereby simplifying the manufacturing/distribution process by eliminating the need for complex copyright clearance and processing.
Solution Approach 2:
Instead of allowing audio recording and then processing it for copyright compliance, the invention inverts the approach by preventing audio recording in the first place when screen recording is detected. This reversal of the normal process eliminates the need for subsequent copyright processing entirely.

AI summary
Provided is a method capable of suppressing generation of data that needs to undergo a complicated copyright process for redistribution thereof. The method includes: executing a program and outputting and displaying a screen generated by the program; reproducing and outputting user-acquired audio acquired arbitrarily by a user; recording the screen output during a specified period along with the user-acquired audio, as video data; and restricting recording of the video data while the user-acquired audio is being output.
