Shared Real-Time Video Editing Architecture for Low Network Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing real-time editing systems face issues with excess arithmetic processing capacity and poor network response due to the one-to-one association of users with editing systems, leading to inefficient use of processing resources and high network traffic.
Innovation Solution
A client-server configuration is implemented, where user interface processing is assigned to a display device, editing data processing to a controller, and video processing to a processor, allowing multiple users to share processing capacity and reducing network traffic by transmitting operation commands and compressed video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one-to-one association between users and editing systems is implemented, then each user has dedicated processing capacity, but the overall processing capacity is considerably in excess when multiple users operate simultaneously
Solution Approach 1:
The patent merges multiple editing systems into a shared infrastructure where multiple users connect to a common editing server through a network. The editing server consolidates processing resources (decoding devices, rendering devices, control devices) that are shared among multiple users, eliminating the need for each user to have a dedicated editing system. This merging approach maintains reliable processing capacity while significantly improving overall resource utilization efficiency.
Solution Approach 2:
The editing server is designed with universal functionality to serve multiple users simultaneously. A single editing server can handle editing tasks from multiple users, providing decoding, rendering, and control functions for each user's editing operations. This multi-functionality allows the system to accommodate varying user needs while optimizing resource usage across the entire user base.
2Ease of operation
If VDI transmits the entire screen in real time, then remote terminal operation is enabled, but network traffic becomes huge and operation response deteriorates
Solution Approach 1:
The patent extracts only the essential elements needed for editing operation from the complete screen transmission approach. Instead of transmitting the entire screen buffer, the system transmits only operation commands (mouse clicks, keyboard inputs, editing instructions) from the terminal to the editing server, and only the necessary video output data from the server to the terminal. This extraction of essential data elements dramatically reduces network traffic while preserving full operational capability.
Solution Approach 2:
The editing server acts as an intermediary that processes operation commands and generates appropriate video output, eliminating the need for direct screen buffer transmission. The server receives high-level operation commands from the terminal, performs the actual editing operations on the video data, and transmits only the resulting video frames or compressed video data back to the terminal. This intermediary approach reduces network traffic from transmitting entire screen buffers to transmitting only essential operation commands and video results.
3Ease of manufacture
If coarse-grained editing process is used, then content-by-content editing is performed, but real-time response is not obtained
Solution Approach 1:
The patent implements dynamic processing that adapts to real-time user operations. The editing server dynamically processes editing operations as they occur, providing real-time feedback and video output updates. The system can adjust processing priorities and allocate resources dynamically based on the current editing state and user interactions, enabling real-time response while maintaining the ability to handle complete content editing tasks. This dynamic approach allows the system to respond immediately to user actions (such as playback, trimming, or effect application) while still completing full editing workflows.

AI summary
A real-time editing system includes a display device configured to be inputted with an operation command representing editing data processing or video processing, a controller configured to receive the operation command from the display device, perform the editing data processing, and generate a processing command instructing the video processing, and a processor configured to receive the processing command from the controller and perform the video processing.
