Display Controller Actual End Time Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display apparatuses face challenges in accurately calculating the actual end time of content due to scheduling errors in electronic program guides (EPG), leading to irrelevant information being displayed to users.
Innovation Solution
An image display apparatus equipped with a controller that checks the expected end time of content, obtains frame data prior to the expected end time, calculates the actual end time based on this data, and provides user interface recommendations for relevant products at the actual end time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information on people or products is provided based on the scheduled timeline in EPG, then users can access information in real time during program playback, but the information may be completely unrelated to the screen the user is watching due to scheduling errors
Solution Approach 1:
The system continuously monitors the actual playback time of content and compares it with the scheduled timeline. When a time deviation is detected, the system adjusts the information provision timing accordingly, creating a feedback loop that ensures information is provided at the correct moment despite scheduling errors
Solution Approach 2:
The system pre-calculates the actual end time of content by analyzing frame data at a first time point before the expected end time. This preliminary calculation allows the system to prepare and provide information at the correct moment, preventing the mismatch between scheduled and actual content timing
2Speed
If information on people or products is provided in real time during program playback, then users can access information immediately, but user satisfaction is low because user preferences are not considered
Solution Approach 1:
The system pre-calculates the actual end time of content before the expected end time by analyzing frame data. This allows the system to prepare personalized information in advance and present it at the optimal moment, considering both timing accuracy and user preferences without delaying information delivery
Solution Approach 2:
The system dynamically adjusts information provision based on user preferences and actual content timing. By making the information system adaptive to user characteristics and actual playback conditions, it maintains real-time responsiveness while personalizing the experience
3Device complexity
If the system uses scheduled EPG timeline for information provision, then the system operation is simple, but scheduling errors cause information to be provided at incorrect times
Solution Approach 1:
The system performs a preliminary calculation of the actual end time by analyzing frame data at a first time point before the expected end time. This advance calculation compensates for scheduling errors without adding complex real-time adjustment mechanisms during playback
Solution Approach 2:
The system introduces an intermediary calculation step that determines the actual end time based on frame data analysis. This intermediary mechanism bridges the gap between the simple scheduled timeline and the need for precise timing, adding minimal complexity while significantly improving accuracy
