Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Producing synchronized Picture-In-Picture (PIP) videos is time-consuming and often results in unsynchronized included videos due to the complexity of the editing process.
Innovation Solution
A method and apparatus that determine reference times for acquiring images and audio based on a program and camera output, using hooking codes to synchronize and combine these elements into a PIP video by calculating intervals and producing frames when they align with the PIP video's frame interval.

Engineering Contradiction Analysis
1Productivity
If traditional video editing process is used to produce PIP video, then one PIP video can be produced by editing two videos, but the two videos included in the produced PIP video may not be synchronized and it takes much time to produce the PIP video
Solution Approach 1:
The patent applies preliminary action by establishing a reference time before the actual video production begins. The reference time is determined based on a first image from a program, a second image from a camera, and audio data. This pre-established reference time serves as a synchronization baseline, allowing the system to automatically align the first and second videos without requiring time-consuming manual editing and synchronization processes.
Solution Approach 2:
The patent implements feedback by continuously comparing the reference time with actual task execution times. The system determines task times for acquiring the first image, second image, and audio, then compares these task times against the reference time. Based on this comparison, the system adjusts and combines the video frames and audio to ensure synchronization, creating a closed-loop control mechanism that maintains precision while improving productivity.
2Ease of manufacture
If additional editing process is performed to produce PIP video, then two videos can be combined into one PIP video, but the process is time-consuming
Solution Approach 1:
The patent applies self-service by enabling the system to automatically determine reference times and synchronize videos without requiring manual intervention. The system autonomously determines the reference time based on program images, camera images, and audio, then automatically combines these elements into a synchronized PIP video. This eliminates the need for manual editing operations, significantly reducing production time while maintaining ease of use.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting time parameters to optimize the production process. The system determines specific task times for acquiring different video and audio elements, then compares these times against the reference time. By changing and optimizing these temporal parameters, the system achieves automatic synchronization without requiring manual editing, thereby reducing production time while maintaining ease of manufacture.
3Ease of operation
If manual video editing is used to create PIP video, then videos can be combined, but synchronization between the two videos is difficult to achieve
Solution Approach 1:
The patent implements feedback by continuously comparing the reference time with actual task execution times. The system determines task times for acquiring the first image, second image, and audio, then compares these task times against the reference time. Based on this comparison, the system adjusts and combines the video frames and audio to ensure synchronization, creating a closed-loop control mechanism that maintains precision while improving productivity.
Solution Approach 2:
The patent replaces the mechanical manual editing process with an automated time-based synchronization system. Instead of requiring manual video editing operations, the system uses temporal parameters and reference times to automatically align video frames and audio. This substitution of the mechanical editing process with a time-based automated system maintains ease of operation while significantly improving synchronization precision.
