Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Limited resources in video processors, such as those in portable devices, lead to inefficient video data processing, resulting in insufficient storage space for compressed video streams and degraded image quality.
Innovation Solution
A stream reprocessing system on chip (SoC) that includes a central processing unit, memory controller, and stream reprocessor, which determines whether to reprocess video data using algorithms like compression, super-resolution, frame rate conversion, and denoising, improving both subjective and objective qualities of video data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video data is compressed using limited resources in portable devices, then processing can be performed, but compression efficiency is insufficient and image quality is degraded
Solution Approach 1:
The system divides video processing into two distinct stages: initial compression using limited portable device resources, and subsequent reprocessing using powerful server resources. This segmentation allows each stage to operate within its resource constraints while achieving overall high quality output.
Solution Approach 2:
The patent introduces an intermediary reprocessing system that receives compressed video data from portable devices and performs additional processing using superior server resources. This intermediary stage bridges the gap between limited mobile resources and high-quality output requirements.
2Manufacturing precision
If more resources are allocated for video processing in portable devices, then image quality improves, but device complexity and resource consumption increase
Solution Approach 1:
The patent extracts the complex reprocessing operations from the portable device and relocates them to a server environment. This extraction allows portable devices to maintain simple, low-resource architectures while still achieving high-quality video processing through the distributed reprocessing system.
3Manufacturing precision
If video data is reprocessed to improve quality, then image quality and compression efficiency improve, but additional storage space is required
Solution Approach 1:
The system performs preliminary compression at the portable device stage, creating a compact intermediate representation that requires minimal storage space. This preliminary action enables subsequent reprocessing without requiring excessive storage resources, as the intermediate compressed form is much smaller than the original uncompressed video data.
