Network Content Distribution Server for Hardware-Free Live Video Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing videoconferencing systems lack a flexible and cost-effective video editing function for live streaming, particularly for online talks and lessons, due to the need for physical hardware switchers that impose installation challenges and location constraints.
Innovation Solution
A content distribution server that receives and synthesizes streamer videos from multiple terminals, allowing for editing and distribution of streaming content via a network without physical constraints, using software-based functions such as screen switching and gesture recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hardware switchers are used for video editing in live streaming, then video editing function is provided, but installation labor and cost increase
Solution Approach 1:
The patent replaces hardware switchers (mechanical system) with software-based video editing functions running on servers. The server receives video streams from multiple cameras, performs switching and editing operations through software, and outputs the edited video stream. This substitution eliminates the need for physical switcher equipment, reducing installation complexity and cost while maintaining video editing capabilities.
2Adaptability or versatility
If hardware switchers are used for video editing, then video editing function is provided, but physical movement of equipment is constrained
Solution Approach 1:
The patent replaces physical switcher equipment with software-based video editing on servers. Since software can be deployed on any server with sufficient computing resources, the system gains location flexibility. The server can be placed anywhere in the network infrastructure, and streamers and editors can access the system from different locations without needing to physically move or transport hardware switchers.
3Adaptability or versatility
If relay terminals are added for network video input, then remote streamer connection is enabled, but equipment size and installation complexity increase
Solution Approach 1:
The patent makes the server perform multiple functions: it receives video streams from multiple cameras, performs video editing through software switching, and distributes the edited stream to multiple viewers. This multi-functional server eliminates the need for separate relay terminals, as the server itself handles all video input, processing, and distribution functions through its network interfaces and software applications.

AI summary
A content distribution server that can provide a content editing function for streaming distribution at a low cost without any physical constraints is provided. Streamer videos from a plurality of streamer terminals are received via a network and stored temporarily in a buffer unit. The plurality of streamer videos in the buffer unit are synthesized to generate an edit screen, which is transmitted to the editor terminal connected via the network. An editor performs an edit operation such as switching selection of the streamer videos, an instruction on screen configuration, and caption input on the edit screen, and transmits the edit operation as edit information from the editing terminal to the content distribution server. The content distribution server generates streaming content from the streamer videos in the buffer unit based on the edit information and distributes the streaming content to a viewer terminal.
