Server Comment Display Adaptation to Video Viewing Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video delivery systems fail to adapt comments to user-selected viewing conditions, leading to mismatched impressions and potential reduction in video appeal due to fixed display sizes and angles of objects.
Innovation Solution
A server device with a video data storage unit and comment data storage unit that associates user comments with specific viewing conditions, ensuring comments are displayed accordingly when viewing conditions are changed by users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If comments are displayed uniformly without considering viewing conditions, then the implementation is simple, but the comments may not be appropriate and may reduce video appeal
Solution Approach 1:
The system performs preliminary action by associating each comment with its corresponding viewing conditions (display size, display angle, object state) before the video is actually viewed. This pre-linking ensures that when the video plays, the appropriate comments are automatically displayed without real-time processing complexity
Solution Approach 2:
The comment data is segmented into multiple records, each associated with specific viewing conditions. Instead of a single uniform comment set, the system divides comments into condition-specific segments, allowing selective display based on current viewing parameters
2Ease of operation
If viewing conditions are changed according to user selection, then user control and video appeal are improved, but mismatched comments may be displayed
Solution Approach 1:
The system implements feedback by continuously monitoring the current viewing conditions (display size, display angle, object state) and automatically selecting comments that match these conditions. This closed-loop approach ensures comment-display consistency without requiring manual intervention
Solution Approach 2:
By pre-associating comments with specific viewing conditions in the data structure, the system eliminates the need for real-time matching calculations. When viewing conditions change, the system simply retrieves the pre-prepared comment set that corresponds to the new conditions

AI summary
Provided is a server device that when, during viewing of a video, viewing conditions for changing states of displayed objects included in the video are changed according to selection by the user, is capable of suppressing display of comments that do not match the viewing conditions of the video. A center server delivers, to a user terminal, replay data for displaying a replay video of which viewing conditions are changed during viewing in accordance with the selection by each user. The center server has a storage unit storing comment data including information about a stamp attached to the replay video and information about the viewing condition under which the replay video should be displayed. The center server, when delivering the replay data, provides the user terminal with the comment data so that the stamp displayed in the replay video is changed in accordance with change of the viewing condition.
