Video Playback System Score-Based Scene Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving image playback systems for sports fail to efficiently allow users to sequentially refer to desired scenes based on game scores, leading to increased user work time and power consumption.
Innovation Solution
A moving image playback system with input, display, and management means that processes time stamps corresponding to play result information, including scores, to rapidly playback desired scenes by associating moving images with effective display objects, optimizing rendering and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional moving image playback systems are used to refer to desired scenes in sports, then all play information is available, but it is not easy to sequentially refer to a moving image of a desired scene due to enormous amount of information
Solution Approach 1:
The patent segments the enormous amount of play information by creating multiple display objects categorized by time stamps and score combinations. Each display object represents a specific game state (e.g., 0-0, 15-0, 30-15), allowing users to navigate through segmented information rather than overwhelming raw data. This segmentation enables easy access to desired scenes by selecting specific score combinations.
Solution Approach 2:
The patent adds a score combination dimension to the traditional time-based playback interface. Instead of only scrolling through time stamps linearly, users can now access scenes by selecting score combinations (e.g., all scenes where the score was 15-0). This dimensional change provides multiple access paths to the same video content, making it easier to find desired scenes.
2Loss of information
If conventional playback systems display all play information, then complete game data is available, but user work time increases due to difficulty in finding desired scenes
Solution Approach 1:
The system performs preliminary organization of play information by pre-categorizing video segments according to time stamps and score combinations before user interaction. Display objects are pre-created and tagged with metadata indicating their corresponding score states. This preliminary action allows users to directly jump to desired scenes without manual searching, significantly reducing work time while preserving all game information.
Solution Approach 2:
The patent introduces display objects as intermediaries between the raw video data and the user. These display objects serve as mediators that encapsulate complex video segments and present them in an organized, score-based format. Users interact with these intermediary objects rather than directly navigating raw video timelines, making information retrieval efficient while maintaining data completeness.
3Loss of information
If conventional systems process and display all game data, then comprehensive information is provided, but power consumption of computer device increases
Solution Approach 1:
The system extracts and displays only the essential play result information (score combinations and time stamps) that users need to navigate the video content. Rather than processing and rendering all raw game data simultaneously, the system extracts key metadata and uses it to create lightweight display objects. This extraction approach maintains information completeness while significantly reducing processing power requirements.
Solution Approach 2:
The patent changes the representation parameters of game data from raw, continuous video streams to discrete, categorized display objects with metadata tags. By transforming the data structure into a more efficient format organized by score combinations and time stamps, the system reduces memory usage and processing requirements while preserving all necessary information for video navigation.
4Adaptability or versatility
If conventional playback systems allow free navigation, then user flexibility is high, but database load increases due to inefficient querying
Solution Approach 1:
The system performs preliminary indexing of video segments by creating display objects tagged with time stamps and score combination metadata before user queries. This pre-organization allows the database to quickly locate desired scenes using indexed fields rather than scanning entire video databases. Users retain flexible navigation capabilities while database load is reduced through efficient query processing.
Solution Approach 2:
The patent applies different data organization strategies to different types of information. Video segments are organized locally within display objects that are grouped by score combinations, rather than using a single centralized database structure. This local organization allows efficient retrieval of specific score-based scenes while maintaining overall system flexibility for various query types.

AI summary
A problem to be solved is to realize a moving image playback system capable of sequentially referring to a desired scene in sports on the basis of at least a score in a game.Realized is a moving image playback system provided with an input means that performs input processing of a time stamp corresponding to play result information including at least a score, a display means that performs display processing of each of a plurality of display objects indicating the play result information and corresponding to the time stamp, and a management means that associates a moving image with the plurality of display objects, in which the display means performs playback processing of the moving image based on the time stamp in response to designation of the display object as a turning point.
