In-Flight Announcement Priority Control for Passenger Entertainment Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional entertainment terminals in airplanes often disrupt passenger entertainment by playing non-essential announcements, leading to passenger discomfort due to the interruption of content playback.
Innovation Solution
A method that determines the importance of announcement sounds and selectively transmits only high-priority sounds to users, storing or blocking lower-priority sounds, using a system comprising an in-flight broadcasting apparatus, translation server, and entertainment server to manage announcement sound presentation based on user language and flight conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all announcement sounds are transmitted to entertainment terminals, then passengers receive complete information, but entertainment content playback is disrupted causing passenger discomfort
Solution Approach 1:
The patent segments announcement sounds into different importance levels (first, second, and third degrees of importance). High-importance announcements are transmitted to entertainment terminals while low-importance ones are blocked, thereby maintaining information completeness for critical announcements while eliminating disruptive noise that causes passenger discomfort.
Solution Approach 2:
The patent applies different quality treatment to different announcement sounds based on their importance. Critical announcements receive full transmission quality, while non-critical announcements are filtered out. This local differentiation ensures that only necessary information reaches passengers through entertainment terminals, preventing disruption to their entertainment experience.
2Reliability
If high-priority announcements are transmitted to all terminals, then important information is delivered, but system complexity increases due to classification requirements
Solution Approach 1:
The patent performs preliminary classification of announcement sounds by importance level at the source (in-flight broadcasting apparatus) before transmission. By pre-categorizing announcements into first, second, and third degrees of importance, the system ensures that only high-priority information is transmitted to entertainment terminals, thereby delivering important information reliably while keeping the classification mechanism simple and centralized.
3Ease of operation
If entertainment terminals are equipped with announcement playback capability, then passengers can receive announcements individually, but the terminals become more complex
Solution Approach 1:
The patent extracts the announcement classification and filtering function from the entertainment terminals and places it in the in-flight broadcasting apparatus. Entertainment terminals only need to receive and playback transmitted audio signals without performing complex classification. This extraction maintains individual announcement reception capability while significantly reducing terminal complexity.

AI summary
A method for presenting a sound, a non-transitory recording medium, a sound presentation system, and a terminal apparatus capable of improving the comfort of a user are provided. A communication unit obtains an announcement sound announced from an utterer to a user in an airplane and a degree of importance of the announcement sound. Next, an in-flight broadcasting priority control unit determines, on the basis of the obtained degree of importance, whether to present the announcement sound to the user. If the in-flight broadcasting priority control unit determines that the announcement sound is to be presented to the user, an in-flight broadcasting control unit transmits the announcement sound to an entertainment terminal used by the user.
