Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video file transcoding processes are inefficient when adding customized information, as they often require a single device to handle both customization and transcoding, leading to long processing times and low efficiency, especially when multiple devices are involved.
Innovation Solution
A video file transcoding system comprising a segmentation device, a transcoding device, and a merging device that splits the video file into fragments, adds customized materials according to transcoding configuration parameters, and merges the transcoded fragments into a complete file, allowing multiple devices to process fragments concurrently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one device is used to add customized information and transcode the video file, then the process is simple to implement, but the processing time is long and transcoding efficiency is low
Solution Approach 1:
The patent divides the video file into multiple video fragments and assigns different fragments to different transcoding devices for parallel processing. The segmentation device splits the original video file based on time duration or data size, enabling multiple devices to work simultaneously on different segments, thereby improving overall transcoding efficiency while maintaining system simplicity.
2Productivity
If multiple devices are used to transcode the video file, then transcoding speed increases, but the customized information adding speed falls behind causing long waiting time
Solution Approach 1:
The patent performs preliminary actions by pre-processing the video file into multiple fragments before transcoding, and pre-configuring the customized information parameters. This allows transcoding devices to immediately begin processing without waiting for file preparation, eliminating idle waiting time and ensuring that customized information can be integrated seamlessly during the transcoding process.
Solution Approach 2:
The patent introduces a segmentation device as an intermediary that prepares video fragments and a merging device that combines results. These intermediary components coordinate the workflow between the customization module and multiple transcoding devices, ensuring that customized information is properly integrated into each fragment without causing bottlenecks or waiting time.
3Ease of operation
If one device adds customized information sequentially, then the customization process is simple to control, but the adding speed cannot keep up with transcoding speed
Solution Approach 1:
The patent segments the customized information processing task by assigning specific customization parameters to each video fragment. Instead of processing customized information sequentially for the entire video file, the system distributes customization tasks across multiple fragments that are processed in parallel by different devices, thereby increasing the overall adding speed while maintaining simple control through standardized fragment processing.
