Overlay Network Video Delivery with Error Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional remote television studios face high costs and inefficiencies in transmitting video feeds over long distances, particularly due to expensive fiber optic infrastructure and limitations in controlling multiple cameras simultaneously.
Innovation Solution
The system employs an overlay network over the Internet with error correction capabilities, using geographically distributed nodes to reduce packet loss and redundancy, allowing for reliable and cost-effective transmission of video streams and enabling remote camera control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fiber optic cable is used for long distance video transmission, then transmission reliability is improved, but installation cost and monthly recurring cost increase significantly
Solution Approach 1:
The patent introduces an overlay network as an intermediary layer built on top of the existing Internet infrastructure. This overlay network includes overlay nodes distributed geographically that work together to transmit video content, thereby avoiding the need for dedicated expensive fiber optic infrastructure while maintaining reliable transmission through multiple intermediate nodes
Solution Approach 2:
The overlay network leverages the existing Internet infrastructure for transmission, making the system universal and compatible with standard network connections. This allows the same infrastructure to serve multiple purposes and multiple users, eliminating the need for dedicated private fiber optic lines for each video transmission
2Reliability
If dedicated control equipment is used for each camera location, then camera control reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal control system where a single control location can control multiple cameras simultaneously through the overlay network. The control commands are transmitted via the same overlay network infrastructure used for video transmission, eliminating the need for separate dedicated control equipment at each camera location
Solution Approach 2:
The patent merges the video transmission function and the camera control function into a single integrated system using the overlay network. Both video content and control commands travel through the same network infrastructure, reducing overall system complexity while maintaining reliable control of multiple cameras from a centralized location
3Manufacturing precision
If experts travel to television studios for interviews, then interview quality is improved, but time cost and expense increase
Solution Approach 1:
The patent creates a virtual copy of the television studio environment through the overlay network, allowing experts to participate in interviews from their remote locations. The system transmits high-quality video and audio streams that replicate the professional studio experience without requiring physical travel, thereby maintaining interview quality while eliminating time and expense associated with travel and on-site preparation
Data Source
AI summary
A system and method for delivering content over the Internet from a content source to a destination is disclosed which includes the use of an overlay network, built on an underlying IP network. Additionally, error correction capability is added to the overlay network to allow the destination to reconstitute packets lost during the transmission over the Internet. In one embodiment, an overlay network is created using a plurality of overlay nodes, which may be geographically distributed, either throughout the country or throughout the world. Each respective content source or destination is also a part of the overlay network. Overhead, capable of providing error correction capability, is added to the content flow as it enters the overlay network. As the content flow leaves the overlay network, this overhead is removed from the content flow. In the case of transmission errors across the overlay network, the overhead information is used to reconstitute lost or corrupted packets.
