Video Size Switching Module for Digital TV Broadcasts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and labor in switching video size modes during digital TV broadcasts, as existing systems either revert to full mode upon tuning or require re-setting video size modes, leading to omitted video portions or unnecessary re-settings.
Innovation Solution
A video processing apparatus and method that includes a control module for storing and switching video size settings based on user preferences, allowing seamless transitions between video size modes without reverting to full mode upon tuning, using a video size switching module to store and apply video size information for specific categories or events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video size mode setting information is stored in nonvolatile memory and the mode is not returned to full mode upon tuning, then user convenience is improved by maintaining preferred video size modes, but video portions may be omitted when viewing different events requiring full mode
Solution Approach 1:
The video processing apparatus dynamically switches between full mode and non-full mode based on real-time detection of side panel presence in the video signal. The system continuously monitors video characteristics and automatically adjusts the display mode without requiring user intervention, thereby maintaining both operational convenience and display adaptability simultaneously.
2Adaptability or versatility
If the video size mode is returned to full mode upon tuning, then video display adaptability is improved by ensuring all video portions are displayed, but user convenience deteriorates as users must re-switch video size modes for each event
Solution Approach 1:
The system performs preliminary detection of side panel presence in the incoming video signal before displaying the content. By detecting whether side panels are present in advance, the apparatus can automatically select the appropriate display mode (full mode or non-full mode) before the user views the content, eliminating the need for manual mode switching while ensuring proper video portion display.
3Manufacturing precision
If manual video size mode switching is required for each event, then video display precision is improved by allowing user selection, but time and labor consumption increases
Solution Approach 1:
The video processing apparatus performs self-service by automatically detecting the presence of side panels in the video signal and autonomously selecting the appropriate display mode. This eliminates the need for user intervention in mode switching, thereby reducing time and labor consumption while maintaining precise video display through automated detection and decision-making.
