Solution Overview

Problem

Existing systems for detecting and recording sports event information from video data often result in erroneous detections, leading to incorrect stats generation, and the delay in event detection makes it difficult for operators to synchronize and verify the information in real-time, thereby reducing operability during the check operation.

Innovation Solution

A display device that captures video data and detects event information, then reproduces the video with a delay that includes displaying event type and occurrence position information before the event occurs, allowing operators to verify the accuracy of automatically generated stats by synchronizing detected events with the video playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If video data is reproduced in real-time without delay, then the operability for operators to verify events is improved, but the detection processing cannot complete accurately because the analysis time is insufficient

Engineering Contradiction:

Improveoperability for verifying eventsVSAvoidaccuracy of event detection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary action by displaying event information in advance before the actual event occurs in the reproduced video. The display control unit displays event type and occurrence position information during a predetermined time period before the event timing, allowing operators to prepare for verification. This resolves the contradiction by enabling accurate detection (through proper analysis time) while maintaining ease of operation (through advance display of event information).

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of displaying events after they occur in real-time video playback, the system inverts the approach by displaying event information beforehand. The video is reproduced with a delay, and event information is shown during the time period before the event actually occurs in the video, allowing operators to anticipate and verify events more effectively.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If video data is reproduced with a delay to allow detection processing, then the accuracy of event detection is improved, but the operability for operators to synchronize and verify information deteriorates

Engineering Contradiction:

Improveaccuracy of event detectionVSAvoidoperability for synchronizing and verifying information

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system displays event information (event type and occurrence position) in advance during a predetermined time period before the event occurs in the reproduced video. This preliminary display allows operators to mentally prepare and synchronize their verification process, resolving the operability issue caused by video delay while maintaining detection accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to operators by displaying detected event information on the display screen before the events occur in the video playback. This feedback mechanism includes event type and occurrence position information, enabling operators to anticipate and verify events effectively despite the video reproduction delay.

Inventive Principle:

Principle #23Feedback

3Device complexity

If event information is displayed only after events occur, then the system complexity is reduced, but the ability to anticipate and verify events is lost

Engineering Contradiction:

Improvesystem complexityVSAvoidability to anticipate and verify events

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The display control unit is configured to display event information during a predetermined time period before the event occurs in the reproduced video. This preliminary display capability enhances operator ability to anticipate and verify events without significantly increasing system complexity, as it utilizes the existing event detection and video delay mechanisms.

Inventive Principle:

Principle #10Preliminary action

AI summary

Upon capture of video data for a match of a sport at a first time, an apparatus performs detection of event information from the captured video data during a first time-period starting from the first time, where the event information includes information identifying an occurrence timing of an event that occurs in the match of the sport, an event type of the event, and an occurrence position of the event. The apparatus reproduces the video data, on a display screen, with a delay by a second time-period obtained by adding a third time-period longer than or equal to a predetermined time-period to the first time-period, and, upon detection of the event information, continues displaying the event type and the occurrence position of the event, for the predetermined time-period, from a timing that is the predetermined time before the occurrence timing of the event within the reproduced video data.
