Solution Overview
Problem
Current multimedia file editing technologies face issues with edition failures, inefficient processing, and low error tolerance due to lengthy transcoding instructions, which are difficult to maintain and troubleshoot, especially in complex video editing scenarios.
Innovation Solution
A method and apparatus for editing multimedia files by acquiring operation information from multiple editing tracks, detecting and editing multimedia file frames in chronological order, and performing encoding synthesis on a frame-by-frame basis, reducing the granularity of encoding and improving control and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional multimedia file editing is performed using integrated transcoding instructions, then the editing process can be completed, but the transcoding instructions become lengthy and complex, making them difficult to maintain and troubleshoot
Solution Approach 1:
The patent divides the transcoding instruction into multiple independent instruction sets, each corresponding to a specific editing track. Each instruction set contains operations for a single track (video, audio, subtitle, etc.), making the system modular and easier to maintain. This segmentation allows individual tracks to be edited independently without affecting others, reducing overall complexity.
Solution Approach 2:
The patent introduces a temporal dimension to the editing process by processing frames in chronological order. Instead of handling all frames at once, the system processes them sequentially through time, which simplifies the instruction structure and makes troubleshooting easier by allowing incremental verification at each time step.
2Reliability
If traditional integrated editing methods are used, then the editing process can be completed, but edition failures occur frequently and error tolerance is low
Solution Approach 1:
By segmenting the editing process into separate instruction sets for each track, the system isolates potential errors to specific tracks rather than affecting the entire editing process. This segmentation improves reliability by containing failures locally while maintaining overall productivity through parallel processing of independent tracks.
Solution Approach 2:
The patent implements feedback mechanisms that allow the system to detect and report edition failures in real-time during the editing process. This feedback enables early detection of errors, allowing the system to correct issues before they propagate through the entire editing process, thereby improving both reliability and productivity.
3Measurement precision
If frame-by-frame encoding synthesis is performed, then control precision and error positioning are improved, but the processing time increases
Solution Approach 1:
The patent segments the encoding synthesis process into separate operations for each editing track, allowing parallel processing. While frame-by-frame processing maintains precision, the segmentation enables multiple tracks to be processed simultaneously, reducing overall processing time while preserving control precision and error positioning capabilities.
