Editing System Using Segmented Resolution Data for Edit Lists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In on-air editing systems, creating a final edit list requires high-resolution video/audio data, which is time-consuming when the data used for creating an Edit Decision List (EDL) and the final edit list have different resolutions, leading to inefficiencies in the editing process.
Innovation Solution
Implementing a system with separate storage and processing for high-resolution and low-resolution video data, where low-resolution data is used to create a preliminary edit list, and then the high-resolution data is used to create the final edit list, with network connectivity allowing efficient transfer and processing between these lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution video data is used to create the EDL, then the final edit list can be created with high quality, but the time to create the EDL increases significantly
Solution Approach 1:
The patent divides the video data into two segments: low-resolution data for EDL creation and high-resolution data for final edit list creation. This segmentation allows each stage to use appropriately resolved data, optimizing both time and quality.
Solution Approach 2:
The patent performs preliminary action by creating the EDL first using low-resolution data, then uses this EDL as a foundation to create the final edit list using high-resolution data. This sequential approach ensures efficient workflow and avoids time-consuming operations.
2Loss of time
If low-resolution video data is used to create the EDL, then the EDL creation time is reduced, but the final edit list cannot be created accurately
Solution Approach 1:
The patent segments the editing process into two distinct stages with different resolution requirements. The first stage uses low-resolution data for rapid EDL creation, while the second stage uses high-resolution data for accurate final edit list creation, ensuring both speed and quality are achieved.
Solution Approach 2:
The patent performs preliminary EDL creation using low-resolution data, then uses this preliminary structure as a foundation to create the final edit list using high-resolution data. This ensures that time is not lost while maintaining accuracy.
3Manufacturing precision
If high-resolution video data is stored and processed throughout the entire editing process, then the final edit list quality is maintained, but the storage capacity and processing requirements increase
Solution Approach 1:
The patent segments the video data storage into two separate storage locations: one for low-resolution data and one for high-resolution data. This segmentation allows the system to store and process data efficiently, using high-resolution data only when necessary for final edit list creation.

AI summary
This invention realizes an editing system and control method thereof capable of significantly improving working efficiency of editing work. A proxy editing terminal device creates an EDL with low-resolution video/audio data, resulting in reducing time to create the EDL. Further, the low-resolution video/audio data and high-resolution video/audio data having the same contents and different resolutions are previously stored, so that the creation of a final edit list with the high-resolution video/audio data based on the EDL can be started in a short time after the EDL is created with the low-resolution video/audio data. Thus working efficiency of the editing work can be significantly reduced with reducing time to create the EDL and the final edit list.
