Neural Network Video Reconstruction for Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing bandwidth requirements for digital video streaming pose challenges, particularly in scenarios where high-definition video transmission leads to network congestion, buffering, and increased costs for consumers, necessitating improved methods for managing video transmission efficiently.
Innovation Solution
A system utilizing a neural network to reduce video resolution and then reconstruct it at higher resolution, coupled with secure communication mechanisms, where the transmitter sends parameters to a receiver to process low-resolution images into high-resolution ones, potentially partitioning images into regions for separate neural network processing.

Engineering Contradiction Analysis
1Measurement precision
If high definition video is transmitted, then video quality is improved, but bandwidth consumption increases
Solution Approach 1:
The transmitter pre-processes the video content by reducing resolution before transmission, and the receiver uses a neural network to reconstruct high-resolution video. This preliminary action of downscaling at the transmitter side reduces bandwidth consumption while the neural network reconstruction at the receiver side restores quality, resolving the contradiction between video quality and bandwidth usage.
Solution Approach 2:
A neural network acts as an intermediary between the transmitted low-resolution video and the desired high-resolution output. The neural network parameters are transmitted separately and used to guide the reconstruction process, enabling quality enhancement without directly transmitting high-resolution data, thus reducing bandwidth consumption while maintaining video quality.
2Measurement precision
If high definition video is transmitted, then video quality is improved, but network congestion and buffering occur
Solution Approach 1:
The system performs resolution reduction at the transmitter before transmission, creating a smaller data stream that can be transmitted more reliably without causing network congestion. The high-resolution quality is then reconstructed at the receiver using neural network parameters, ensuring both streaming stability and video quality are maintained simultaneously.
3Measurement precision
If high definition video is transmitted, then video quality is improved, but transmission costs increase
Solution Approach 1:
The transmitter pre-reduces video resolution before transmission, significantly lowering the bandwidth requirements and associated transmission costs. The neural network reconstruction at the receiver side restores high-definition quality without requiring expensive high-bandwidth transmission, thus resolving the contradiction between video quality and transmission cost.
Solution Approach 2:
The neural network serves as an intermediary that enables quality enhancement without requiring proportional bandwidth investment. By transmitting compact low-resolution video plus neural network parameters instead of full high-resolution video, the system achieves cost-effective quality improvement.

AI summary
Systems, apparatuses, and methods for enhanced resolution video and security via machine learning are disclosed. A transmitter reduces a resolution of each image of a videostream from a first, higher image resolution to a second, lower image resolution. The transmitter generates a set of parameters for programming a neural network to reconstruct a version of each image at the first image resolution. Then, the transmitter sends the images at the second image resolution to the receiver, along with the first set of parameters. The receiver programs a neural network with the first set of parameters and uses the neural network to reconstruct versions of the images at the first image resolution. The transmitter can send the first set of parameters to the receiver via a secure channel, ensuring that only the receiver can decode the images from the second image resolution to the first image resolution.
