Video Reception Device Priority-Based Composition Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video receiving apparatuses do not effectively facilitate user selection of retrieval items by presenting a clear association between video content and partial content items, such as characters or images, within the video content.
Innovation Solution
A video receiving apparatus that includes a receiving unit, an extracting unit to analyze video content and extract partial content items, an information generating unit to create composition information items, a priority setting unit to determine the degree of association based on features like display size, position, and audio characteristics, and a display control unit to prioritize and display these items on a screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple composition information items are displayed without priority ranking, then all retrieval items are presented to users, but users cannot easily identify which items are most relevant to the video content
Solution Approach 1:
The patent applies parameter changes by introducing a priority parameter that quantifies the degree of association between composition information items and video content. This priority parameter is calculated based on multiple factors including the proportion of the partial content item in the video content, the display position of the partial content item, and the display size of the partial content item. By changing the display parameters (position, size, ordering) based on the calculated priority, the system effectively communicates relevance to users without losing any retrieval item information.
2Ease of operation
If priority-based display is implemented, then user selection is facilitated, but additional processing complexity is introduced to calculate and manage priority levels
Solution Approach 1:
The patent applies segmentation by breaking down the priority calculation into distinct, manageable components. The degree of association is calculated separately for each composition information item based on specific features: the proportion of the partial content item in the video content, the display position, and the display size. Each feature is evaluated independently and then combined to determine the overall priority. This segmented approach reduces computational complexity compared to a holistic analysis of all items simultaneously.
Solution Approach 2:
The patent uses parameter changes to simplify priority calculation by defining specific, measurable parameters for each composition information item. These parameters include the proportion of the partial content item (calculated as the ratio of the area of the partial content item to the area of the entire video content), the display position (coordinates or relative position), and the display size (dimensions). By changing these parameters and using them in a standardized calculation formula, the system achieves efficient priority determination without excessive complexity.
3Loss of information
If all composition information items are displayed with equal prominence, then complete information is provided, but the association with video content is not clearly highlighted
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of composition information items based on their individual priority levels. Instead of uniform display, each item receives localized treatment in terms of display position, display size, and ordering. Items with higher priority (stronger association with video content) are displayed with greater prominence, such as larger size, more central positioning, or higher placement in the list. This local differentiation maintains information completeness while precisely indicating the degree of association for each item.
Solution Approach 2:
The patent uses parameter changes to precisely indicate the degree of association by dynamically adjusting display parameters based on calculated priority values. The display position parameter is changed to place higher-priority items in more prominent locations. The display size parameter is adjusted to make higher-priority items larger or more visually prominent. The ordering parameter is modified to sequence items by priority level. These parameter changes provide a precise visual representation of the association degree without losing any information.

AI summary
A video receiving apparatus (1) includes: a receiving unit (101) which receives video content; an extracting unit (102) which extracts a partial content which is a portion of the video content by analyzing the video content, to obtain a feature of the partial content item, the feature being characteristic within the video content; an information generating unit (103) which generates a composition information item indicating the partial content item and including at least one of a character and an image; a priority setting unit (105) which sets a priority of the composition information item based on the feature obtained from the partial content item, the priority indicating a degree of association between the video content and the composition information item; and a display control unit (107) which controls display of the composition information item on a display screen according to the priority of the composition information item set by the priority setting unit (105).
