Recording Mode Selection Based on Available Storage Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern electronic devices, such as cellular phones, have limited storage capacity, making it difficult to record high-quality video and audio for extended periods without running out of space, as they do not effectively determine a specific recording length based on varying resolution and compression options.
Innovation Solution
An electronic device determines an initial recording mode and calculates the maximum recording length based on available storage space, issuing a warning if it falls below a threshold, allowing users to select an alternate recording mode to extend the recording time by altering video and audio parameters, such as resolution and compression, and providing a live preview of the changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high quality recording mode is used, then recording quality is improved, but recording duration is reduced due to limited storage capacity
Solution Approach 1:
The system dynamically adjusts recording parameters (resolution, frame rate, bitrate) based on available storage space and user needs. The recording mode is not fixed but can be changed in real-time to optimize between quality and duration, allowing the device to adapt to different storage conditions and user requirements.
Solution Approach 2:
The patent changes multiple recording parameters simultaneously (video resolution, frame rate, audio bitrate, compression settings) to achieve the desired balance between quality and duration. By adjusting these parameters, the system can extend recording duration while maintaining acceptable quality, or vice versa, depending on storage availability.
2Duration of action of moving object
If lower resolution and greater compression are applied, then recording duration is extended, but recording quality deteriorates
Solution Approach 1:
The system provides dynamic control over recording parameters, allowing users to adjust resolution, frame rate, and compression settings in real-time based on available storage space. This enables flexible optimization between duration and quality rather than being locked into fixed presets.
Solution Approach 2:
The system applies compression selectively based on available storage space. When storage is limited, compression is increased; when storage is abundant, compression is reduced or eliminated. This partial application of compression allows the system to extend duration only when necessary while preserving quality when possible.
3Ease of operation
If fixed recording mode is used, then device operation is simplified, but adaptability to storage conditions is reduced
Solution Approach 1:
The system automatically monitors available storage space and calculates optimal recording parameters without requiring manual user intervention. It self-adjusts recording modes based on current storage conditions, providing both simplicity and adaptability simultaneously.
Solution Approach 2:
The system continuously monitors storage space and provides feedback to both the user interface and the recording engine. This feedback loop enables automatic adjustment of recording parameters to match current storage conditions, maintaining both ease of operation and adaptability.

AI summary
A method, system, and computer program product for selecting a recording mode used by audio and/or video input devices on a device. The method includes determining an initial recording mode associated with a live recording on an electronic device. In response to determining the initial recording mode, the electronic device determines, based on the initial recording mode, a maximum recording length of the live recording that may be stored in available free space. In response to determining the maximum recording length is less than the predetermined threshold, the electronic device issues a warning that includes the maximum recording length to at least one output device. The method further includes enabling entry of a first response to the warning that includes an identification of an alternate recording mode and that extends the maximum recording length for the live recording within the at least one storage device.
