Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple videos from different viewpoints are transmitted to enable user selection, then video selection flexibility is improved, but transmission bandwidth consumption increases
Solution Approach 1:
The patent extracts only the necessary video segments for transmission by pre-selecting high-quality videos based on user ratings and event importance. Instead of transmitting all available viewpoint videos, the system extracts and transmits only the most relevant segments, reducing bandwidth consumption while maintaining selection flexibility for important events.
Solution Approach 2:
The system performs preliminary selection of videos based on user ratings and event significance before transmission. By pre-processing and pre-selecting which videos to transmit based on anticipated user interests and important moments, the system reduces the volume of data that needs to be transmitted while ensuring that flexible video selection is available for the most important content.
2Manufacturing precision
If video quality is maintained at high levels, then viewing experience is improved, but transmission bandwidth requirements increase
Solution Approach 1:
The patent applies different quality levels to different video segments based on their importance. High-quality transmission is reserved for segments containing important events or highly rated content, while less critical segments are transmitted at lower quality. This local differentiation of quality maintains excellent viewing experience for important content while reducing overall bandwidth consumption.
Solution Approach 2:
The system dynamically changes video quality parameters based on content importance and user preferences. By adjusting resolution, bitrate, and compression levels according to the significance of the event and user rating, the system optimizes the balance between video quality and bandwidth usage, delivering high quality where needed and reducing quality where acceptable.
3Reliability
If videos are selected based on user ratings, then user satisfaction is improved, but system complexity increases due to rating collection and processing
Solution Approach 1:
The patent implements a self-service rating system where users automatically provide feedback by interacting with the video content. The system collects ratings through simple user actions such as pausing, replaying, or selecting specific viewpoints, eliminating the need for complex manual rating interfaces. This self-service approach improves user satisfaction through personalized content selection while keeping the system relatively simple by leveraging natural user interactions.
Solution Approach 2:
The system implements a feedback loop where user interactions with videos (pausing, replaying, viewpoint selection) automatically generate rating data. This feedback mechanism continuously improves video selection accuracy based on actual user behavior rather than requiring complex explicit rating systems, thereby improving user satisfaction while maintaining system simplicity through automatic learning from user patterns.
4Reliability
If continuous video delivery is ensured, then service reliability is improved, but bandwidth consumption increases to avoid blind spots
Solution Approach 1:
The patent merges multiple video streams into a single continuous delivery by selecting and concatenating segments from different viewpoint videos based on their temporal overlap and content importance. Instead of transmitting all viewpoint videos simultaneously to ensure continuity, the system intelligently merges segments from multiple sources into one continuous stream, maintaining service reliability while significantly reducing bandwidth consumption through selective combination.
Data Source
AI summary
A terminal and method for receiving a video delivery of a video signal are provided. The method includes receiving, from a server, the video signal for successively replaying a set of videos selected from among a plurality of videos. The selected videos are respectively selected for each of a plurality of periods in accordance with rating values of the plurality of videos. The rating values are given by a plurality of users. The plurality of videos is obtained by taking an identical scene from a plurality of different viewpoints over a plurality of successive periods. The method further includes successively replaying the selected videos in accordance with the video signal, displaying any video among the plurality of videos, and further displaying when any subject is selected by a user from among a plurality of subjects included in the displayed video, a menu for rating the selected subject.
