Solution Overview

Problem

In electronic terminals with split screen functionality, recording screen content while multiple applications play audio simultaneously results in mixed sounds, making it difficult to isolate and record the intended audio source accurately.

Innovation Solution

A screen recording method and device that allow users to select and record audio from specific split screen areas, distinguishing between recording and non-recording objects, and optionally recording external environment sounds, ensuring that the recorded audio corresponds to the intended application without interference from other applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple applications play audio simultaneously in split screen mode, then the screen recording captures all audio sources, but the recorded sound becomes mixed and indistinguishable

Engineering Contradiction:
Improvenumber of audio sources recordedVSAvoidaudio source distinguishability
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

The patent segments the audio recording process by allowing users to select specific split screen areas as target objects. The system then records audio only from the selected target area rather than mixing all audio sources. This segmentation is implemented through the target object determination module that identifies and isolates audio from specific applications, enabling clear recording of individual audio sources even when multiple applications play simultaneously.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If the system records audio from all split screen areas, then complete audio coverage is achieved, but the recorded audio becomes a mixture that cannot be clearly attributed to specific applications

Engineering Contradiction:
Improveaudio coverageVSAvoidaudio source identification accuracy
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent extracts the desired audio source from the mixture by allowing users to select a specific target object (split screen area) for recording. The system then extracts audio only from that selected area, separating it from other audio sources. This is achieved through the audio data acquisition module that captures audio specifically from the target application, enabling precise audio source identification while maintaining complete coverage of available audio sources for selection.

Inventive Principle:
Principle #2Taking out (Extraction)

3Area of stationary object

If the screen recording function records all visible content, then comprehensive screen capture is achieved, but the audio does not correspond to the intended application

Engineering Contradiction:
Improvescreen capture coverageVSAvoidaudio-visual correspondence
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The patent applies local quality by allowing different parts of the screen (split screen areas) to have different recording qualities or states. The target object determination module identifies which specific area should be recorded, and the system then records both video from that specific area and audio from the corresponding application. This ensures that the audio-visual content in the recording corresponds to the same application, improving reliability while maintaining the ability to capture multiple areas on screen.

Inventive Principle:
Principle #3Local quality

AI summary

A screen recording method includes displaying an interface including a plurality of split screen areas; determining a target object in response to an initiation of a screen recording function, the determined target object including at least one of the plurality of split screen areas; based on a determination that the target object includes a plurality of audio sources that are playing at the same time, receiving a selection of at least one audio source among the plurality of audio sources; and recording screen display content and the at least one audio source of the target object to generate a screen recording file.
