Server Late Arrival Event Video Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Visitors who cannot arrive at an event venue by the start time of an event may miss part of the event, reducing their satisfaction.
Innovation Solution
A server system that detects a visitor's target time for arriving at the event venue and, if later than the event start time, transmits a shortened moving image of the event from the start time to the target time, followed by a live moving image after the shortened playback ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the visitor arrives late to the event venue, then the visitor can still attend the event, but the visitor misses part of the event content
Solution Approach 1:
The server performs preliminary action by transmitting the first shortened moving image (recording from event start to target time) to the terminal device before the visitor arrives at the venue. This allows the visitor to view the missed event content in advance during their commute, compensating for the late arrival without losing event information.
Solution Approach 2:
The server acts as an intermediary by providing the shortened moving image as a bridge between the event start and the visitor's arrival. This intermediary content fills the information gap that would otherwise exist due to the time delay, allowing seamless transition to live viewing upon arrival.
2Ease of operation
If the server transmits only live moving image to late arrivals, then the transmission is simple, but the visitor cannot experience the event from the beginning
Solution Approach 1:
The event content is segmented into two parts: the first shortened moving image (from event start to target time) and the second shortened moving image (from target time to current time). This segmentation allows the server to provide only the relevant historical portion to late arrivals, rather than transmitting the entire event from beginning, maintaining simplicity while ensuring complete information delivery.
3Loss of information
If the server provides complete event recording to late visitors, then the visitor experiences full event content, but the data transmission volume is large
Solution Approach 1:
The server extracts only the necessary portion of the event recording (from event start to target time) to create the first shortened moving image. This extraction provides complete event content information while minimizing data transmission volume by excluding redundant portions that the visitor would have seen if arrived on time.
4Loss of information
If the server transmits both shortened moving image and live moving image, then the visitor experiences seamless event coverage, but the system complexity increases
Solution Approach 1:
The system dynamically adjusts the content transmission based on the visitor's arrival time. The server determines whether to transmit the first shortened moving image, second shortened moving image, or live moving image based on real-time conditions. This dynamic approach provides seamless event coverage while managing system complexity through conditional logic rather than permanent complex architecture.

AI summary
A server includes a communication unit and a control unit. The control unit obtains, as a target time, a time when a predetermined trigger is detected for a visitor moving to an event venue. When the target time is later than a start time of an event held at the event venue, by controlling the communication unit such that the communication unit transmits a first shortened moving image obtained by shortening a first moving image of the event shot from the start time to the target time, the control unit presents the first shortened moving image to the moving visitor. After a playback of the first shortened moving image ends, by controlling the communication unit such that the communication unit transmits a live moving image of the event, the control unit presents the live moving image to the moving visitor.
