Remote Live Stream Editing via Buffered Content Distribution
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 provides a software-based video editing solution, allowing streamers and editors to manage and distribute streaming content from multiple terminals via a network without physical constraints, using a streamer video receiving unit, buffer, edit screen generation, edit information transmission, and streaming content generation units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hardware switchers are used for video editing in live streaming distribution, then video editing function is provided, but equipment configuration becomes large and installation becomes complex
Solution Approach 1:
The patent replaces hardware switchers (mechanical/electrical system) with a software-based video editing function integrated into the content distribution server. This substitution eliminates the need for separate physical switcher equipment, terminal relays, and complex hardware connections, thereby simplifying the overall equipment configuration and making installation much easier while maintaining the video editing capability.
2Adaptability or versatility
If hardware switchers are used for video editing, then video switching function is provided, but physical movement of equipment becomes constrained
Solution Approach 1:
By replacing the mechanical hardware switcher with a software-based solution integrated into the content distribution server, the system eliminates physical equipment that needs to be transported. The video editing function becomes virtually accessible from any location with network connectivity, significantly improving location flexibility and adaptability for streamers and editors.
3Adaptability or versatility
If terminal relays are added for network video input, then remote streamer connection is enabled, but equipment size and installation cost increase
Solution Approach 1:
The patent merges the video editing function directly into the content distribution server that already handles network video inputs from remote streamers. This integration eliminates the need for separate terminal relays and additional hardware components, thereby maintaining network connectivity capabilities while reducing overall equipment configuration complexity and installation cost.
Data Source
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.
