Video Transition Confidence Region Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition between video sequences is delayed due to latency in data transmission, causing the transition to not occur immediately when the user requests it, especially when the transmission delay approaches or exceeds one second.
Innovation Solution
A method and device that utilize pre-transition images and confidence values to determine a confidence region, allowing for a smoother transition by displaying a transition image based on the reliability of data blocks, which is dependent on the number of images received from the second video sequence, thereby preventing the display from freezing during the transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system waits for video data to be received before performing transition, then the transition accuracy is improved, but the transition delay increases
Solution Approach 1:
The system performs preliminary actions by generating transition images using confidence regions and pre-transition images before the second video sequence data is fully received. This allows the transition to start earlier while maintaining quality through the confidence-based rendering approach.
Solution Approach 2:
The patent introduces transition images as an intermediary element between the first and second video sequences. These transition images are generated using confidence regions that predict what the second sequence should look like based on the first sequence, allowing smooth transitions without waiting for full data reception.
2Speed
If the system performs transition immediately without waiting for video data, then the transition speed is improved, but the display quality deteriorates
Solution Approach 1:
The system changes parameters by adjusting the confidence threshold and the number of pre-transition images used in the transition. This allows dynamic control of transition quality and speed, enabling the system to maintain display quality while performing transitions at higher speeds by optimizing these parameters.
Solution Approach 2:
The patent applies partial action by using only the necessary portion of the second video sequence data that has been received so far, combined with confidence region prediction, to generate transition images. This allows the transition to proceed with partial data rather than waiting for complete data reception.
3Measurement precision
If the system uses traditional transition method waiting for data reception, then the transition accuracy is improved, but the user experience deteriorates due to display freezing
Solution Approach 1:
The system ensures continuity of useful action by continuously generating and displaying transition images during the data reception period, rather than freezing the display. The transition process continues smoothly with updated transition images as more data becomes available, maintaining user engagement and experience.

AI summary
A method for transitioning between an image of a first video sequence and an image of a second video sequence, wherein an image of the video sequences corresponds to one sub-region of a respective image of the other video sequence, receiving one image from the first video sequence; providing, from the one image, one pre-transition image; for each one pre-transition image: determining a confidence region within the one pre-transition image based on a set of confidence values, each confidence value representing, for a respective block of the one pre-transition image, the level of reliability of determining one or more blocks of a corresponding image in the second video sequence; computing a transition image corresponding to the second video sequence, the transition image being a function of the determined confidence region of the pre-transition image; and displaying the transition image for a duration upon the reception of the second video sequence.
