Geometric Pixel Scattering for Resilient Video Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transporting uncompressed media over IP networks are inefficient due to reliance on complete replication for reliability, which is wasteful in terms of network resources and prone to burst losses that can result in significant image distortion.
Innovation Solution
Applying a geometric transform to scatter pixels across packets, allowing for error recovery by using surrounding pixel data when packets are lost, and facilitating the insertion of supplementary content while maintaining image integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete replication of the target media stream is used to ensure reliability, then reliability is improved, but network resource efficiency deteriorates
Solution Approach 1:
The patent segments the video stream into individual packets for transmission over the IP network. Each packet contains a portion of the video data and can be independently transmitted and received. This segmentation allows for selective retransmission of only lost or corrupted packets rather than requiring complete replication of the entire media stream, thereby improving network resource efficiency while maintaining reliability.
2Reliability
If complete replication of the target media stream is used to ensure reliability, then reliability is improved, but network resource consumption increases
Solution Approach 1:
The patent implements partial replication by sending the main video stream once and optionally retransmitting only specific lost packets rather than replicating the entire stream multiple times. This partial action approach reduces network resource consumption compared to complete replication while still achieving the desired reliability through selective retransmission of critical data portions.
3Ease of operation
If traditional packet transmission is used, then transmission simplicity is maintained, but error recovery capability deteriorates during packet loss
Solution Approach 1:
The patent introduces an intermediary error recovery mechanism that operates between the simple packet transmission and the final video reconstruction. The system uses packet sequence numbers and error detection codes as intermediaries to identify lost packets, and implements a selective retransmission protocol that mediates between the transmitted data and the reconstruction process, thereby enhancing error recovery capability while maintaining transmission simplicity.
Data Source
AI summary
Systems, methods, and computer program products relating to resilient transmission of a media stream over a communication network. A plurality of data packets are received over a communications network. The plurality of data packets relate to a first source video portion transformed using a geometric transform. The geometric transform is configured to modify a location of pixels in the first source video portion such that a plurality of adjacent pixels in the first source video portion are not adjacent after transformation. A received video portion is assembled based on the plurality of data packets. The received video portion is transformed, using an inverse of the geometric transform, to generate a second source video portion. The second source video portion and the first source video portion include a plurality of matching pixels.
