Originating Client Buffering for Complete Video Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current live-streaming systems prioritize real-time delivery over quality and reliability, leading to video loss during network disruptions and increased user effort in high-end performance analysis, especially when multiple camera angles are used.
Innovation Solution
An originating client buffers video streams at variable bandwidths, incorporating timecodes for synchronization, and uses event recognition software to generate clips, allowing for delayed but complete video delivery and flexible network usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If live-streaming systems adjust video parameters (resolution, frame-rate) to maintain real-time delivery, then the real-time nature of the stream is maintained, but video quality and completeness deteriorate during network disruptions
Solution Approach 1:
The system performs preliminary buffering of video segments at the originating client before network transmission. This allows the video to be captured and stored locally with full quality, then transmitted when network conditions permit, ensuring no video loss during network disruptions while maintaining the ability to deliver content reliably
2Reliability
If video is recorded locally and then transferred to a computer for review, then video quality and completeness are maintained, but user effort and time required increase dramatically
Solution Approach 1:
The system merges the recording function, buffering capability, and streaming transmission into a single integrated originating client device. This eliminates the need for separate recording devices and manual transfer steps, allowing users to capture and stream video directly from one device while maintaining full video quality and completeness
Solution Approach 2:
The originating client automatically manages video buffering, segmentation, and transmission without requiring user intervention. The system self-manages the entire workflow from capture to delivery, eliminating manual steps such as finding files, transferring between devices, and editing clips
3Reliability
If multiple camera angles are used in high-end performance analysis, then video quality and reliability improve, but the amount of work and complexity for the user increases dramatically
Solution Approach 1:
The originating client is designed as a universal platform that can simultaneously handle multiple camera inputs, buffer multiple video streams, and manage synchronization across different angles. This multi-functional capability allows the system to process multiple camera angles without increasing user workload or system complexity
4Speed
If network bandwidth is restricted, then real-time streaming is maintained by lowering video parameters, but video resolution and quality deteriorate
Solution Approach 1:
The system buffers video segments at the originating client before transmission, allowing full-resolution video to be captured and stored locally. When network bandwidth is restricted, the buffered video can be transmitted at lower speeds without compromising the original capture quality, as the buffering absorbs the bandwidth variations

AI summary
A recorded event presentation system, including a camera that is adapted to capture and provide a video stream at a resolution. An originating client is adapted to receive the video stream from the camera at the resolution and provide the entire video stream at the resolution across a network at a variable bandwidth. When the bandwidth is relatively larger, then the video stream is provided at the resolution at a relatively faster speed. When the bandwidth is relatively smaller, then the video stream is provided at the resolution at a relatively slower speed. A server is adapted to receive the video stream from the originating client, and provide the video stream to a viewing client.
