Terminal Display Resolution Enhancement via Hybrid Image Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital multimedia broadcasting (DMB) terminals face issues with image quality when connected to large-sized displays, as the resolution suitable for the DMB terminal is not optimized for larger screens, resulting in unsatisfactory image quality due to the inherent limitations of the DMB service's resolution.
Innovation Solution
A terminal configuration that combines basic image information received by an antenna with additional image information from an external device, using up-sampling and image processing to enhance the image quality on larger displays, and provides data availability notifications, utilizing various communication methods such as RF, 3G/4G, and Wi-Fi for improved resolution and data management.

Engineering Contradiction Analysis
1Manufacturing precision
If DMB broadcasting with QVGA resolution is displayed on a VGA display unit, then the terminal can display content, but the image quality becomes unsatisfactory due to resolution mismatch
Solution Approach 1:
The patent segments the image information into two parts: basic image information received via RF communication and additional image information received via mobile communication. By dividing the image data transmission into multiple channels with different communication methods, the system can combine low-resolution basic information with high-resolution additional information to achieve overall high-quality display without overwhelming a single communication channel
Solution Approach 2:
The patent merges basic image information and additional image information through image processing to produce combined image information with enhanced resolution. The controller combines the QVGA basic image with higher-resolution additional image data to generate VGA-quality combined image information, thereby improving image quality while utilizing multiple communication sources
2Manufacturing precision
If additional image information is received from external devices to improve resolution, then image quality improves, but data management complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the controller monitors the availability and quality of additional image information from external devices. The system continuously assesses whether additional image information is available and adjusts its operation accordingly, providing notifications to users about data availability and automatically managing the combination process based on real-time conditions
Solution Approach 2:
The system performs self-service by automatically managing the reception, processing, and combination of basic and additional image information without requiring manual user intervention. The controller autonomously determines when to receive additional image information, processes the combination, and manages data flow between communication units, reducing the burden on users while improving image quality

AI summary
A terminal, a vehicle having the same, and a method of controlling the same are provided. The terminal includes a display unit, a first communication unit that is configured to receive basic image information, and a second communication unit that configured to receive additional image information. A controller is configured to combine the basic image information and the additional image information, and display an image on the display unit based on the combined image information when resolution supported in the display unit is greater than resolution of the basic image information. A broadcasting image of high resolution is provided to the user since the resolution of the DMB of the terminal is increased by receiving the additional image information to improve the resolution via a wireless communication network of a predetermined band or greater.
