Gateway Image Resolution Enhancement via Motion Vector Re-search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gateway apparatuses currently transmit image signals from terminals connected to narrower networks to those on wider networks without enhancing resolution or image quality, resulting in insufficient image display on the receiving terminals, which limits service subscriber growth.
Innovation Solution
A gateway apparatus that receives image signals from a first terminal, enhances their resolution and quality through decoding, super-resolution conversion, and encodes them for transmission to a second terminal on a wider network, utilizing techniques like motion vector re-search and edge detection to improve pixel density and frame rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the gateway apparatus transmits image signals directly from the first network to the second network without conversion, then the device complexity is reduced, but the image resolution and quality become insufficient for display on second terminals
Solution Approach 1:
The gateway apparatus changes the resolution parameter of the image signal by performing super-resolution conversion. The conversion unit processes the image signal from the first network, enhancing its resolution and quality parameters before transmitting to the second network, thereby resolving the contradiction between maintaining simple transmission and achieving high image quality
Solution Approach 2:
The gateway apparatus acts as an intermediary between the first network and the second network. It receives image signals from the first network, performs conversion processing to enhance resolution and quality, and then transmits the converted signals to the second network. This intermediary role allows the system to improve image quality without requiring direct high-quality transmission from the first network
2Manufacturing precision
If the gateway apparatus performs super-resolution conversion to enhance image quality, then the image resolution and quality are improved, but the processing time and computational resources increase
Solution Approach 1:
The gateway apparatus performs super-resolution conversion in advance before the image signal reaches the second network. By pre-processing and enhancing the resolution and quality of the image signal at the gateway, the system prepares high-quality images ahead of time, reducing the processing burden on the second network and terminal devices
