Streaming Content Upscaling for Real-Time Artifact Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing streaming media content often suffers from reduced quality due to compression, resulting in lower resolution and the presence of artifacts like blurriness, blockiness, and chromatic aberration, with existing solutions either failing to improve quality sufficiently or being too heavy for real-time client device processing.
Innovation Solution
A lightweight deep learning-based approach using neural networks for real-time upscaling and artifact removal on client devices, employing architectures like UNet-like CNNs and ESRGAN, which can enhance video and image content without requiring motion vectors or optical flow data, and are optimized for specific hardware.

1Quantity of substance
If content is compressed or encoded to reduce size for transmission, then bandwidth constraints and data limits are addressed, but content quality deteriorates with reduced resolution and artifacts
Solution Approach 1:
A neural network model acts as an intermediary between the compressed streaming content and the final displayed content. The model processes the low-quality input and generates enhanced output with improved resolution and reduced artifacts, effectively mediating the quality degradation caused by compression
Solution Approach 2:
Traditional mechanical upscaling methods are replaced with a deep learning-based neural network system. The model learns complex patterns and relationships from training data to perform intelligent enhancement, substituting simple interpolation algorithms with sophisticated pattern recognition
2Manufacturing precision
If existing quality improvement solutions are applied, then content quality may be improved, but they are too heavy for real-time client device processing
Solution Approach 1:
The model architecture parameters are optimized for mobile deployment, including reducing the number of layers, filters, and parameters while maintaining enhancement effectiveness. This allows the model to run in real-time on client devices with limited computational resources
Solution Approach 2:
The enhancement process is segmented into discrete processing stages that can be executed efficiently on mobile hardware. The model is divided into manageable computational blocks that can be processed sequentially or in parallel depending on device capabilities
3Loss of time
If real-time enhancement is implemented on client devices, then latency is reduced, but device resources are constrained
Solution Approach 1:
The model is specifically designed with parameters optimized for real-time execution on mobile devices, balancing computational complexity with processing speed. This enables the model to deliver enhancement results within acceptable latency thresholds while consuming manageable device resources

AI summary
Real time content enhancement can be provided using a solution that is lightweight enough to operate on client devices, even for high resolution, high bitrate content. An enhancement process can include a neural network that upscales the content to a target resolution while also enhancing a visual quality of the content, such as to sharpen visual aspects of the content and reduce a presence of artifacts. Such an approach can enable compressed content to be transmitted in streams across a network, in order to conserve bandwidth and data transmission, while also enabling that content to be upscaled and enhanced at the client device in real time, such that a user or viewer can experience the content at, near, or above its intended or original visual quality.
