Edge All-in-one Machine for Local Video Stream Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video transmission systems in logistics warehouses consume large amounts of network bandwidth due to the simultaneous recording and playback of video streams across multiple workstations, leading to network congestion and unstable video monitoring.
Innovation Solution
Implementing a method for media stream transmission based on an edge device, where an edge all-in-one machine receives live streaming requests, generates media stream service information, and transmits media streams directly within a local area network, reducing reliance on public network bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video streams are transmitted through public network to multiple workstations, then video monitoring coverage is improved, but network bandwidth consumption increases significantly
Solution Approach 1:
The system segments video stream transmission by deploying edge all-in-one machines in different network zones (warehouse areas). Each edge device serves a specific local area, receiving video streams from cameras in its vicinity and providing playback services to workstations in that same area. This segmentation prevents all workstations from competing for the same public network bandwidth, as each zone handles its own video traffic independently through the local edge device.
2Productivity
If multiple workstations play video streams simultaneously through public network, then real-time monitoring capability is improved, but video transmission stability deteriorates
Solution Approach 1:
The edge all-in-one machines perform preliminary actions by pre-receiving and caching video streams from cameras before playback requests arrive. When workstations need to play video streams, the edge device already has the stream data ready in its local buffer, allowing immediate playback without requiring real-time transmission through the unstable public network. This preliminary caching action ensures stable video delivery even under high concurrent access conditions.
3Ease of operation
If video streams are routed through cloud module, then system management flexibility is improved, but network resource occupation increases
Solution Approach 1:
The system extracts video stream transmission from the public network path and routes it through private local networks via edge devices. The cloud module retains only management and control functions (taking out the playback function from centralized cloud), while actual video data flows locally through edge all-in-one machines. This extraction eliminates the need for video streams to traverse the public network to reach workstations, significantly reducing network resource occupation while preserving cloud-based management flexibility.

AI summary
The present application discloses a method and an apparatus for a media stream transmission based on an edge device, and an electronic device. The method includes: an edge all-in-one machine located in a second network receives a live streaming request message from a station device management cloud module in a first network, generates media stream service information based on an identifier of a camera module, and sends the media stream service information to the station device management cloud module to cause the station device management cloud module to request a media stream from a target network video recorder. The edge all-in-one machine further receives the media stream recorded by the target network video recorder through the camera module, and transmits the media stream to a client based on the edge live streaming address.
