Multimedia Exercise Content Playback Speed Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia exercise content systems fail to adapt to individual user exercise amounts and health information, leading to discomfort and boredom during workouts, as they do not provide personalized exercise routing based on user-specific physical conditions.
Innovation Solution
A display method and multimedia apparatus that adjust the reproduction rate of multimedia exercise content according to user exercise speed and physical information, providing guidance messages and UI elements when the exercise speed deviates from recommended criteria, and outputting cheering or completion messages based on exercise thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same pattern exercise contents are provided to all users regardless of exercise amount, then the system is simple and easy to operate, but the user becomes bored and uncomfortable exercising
Solution Approach 1:
The exercise content reproduction rate is dynamically adjusted based on real-time exercise amount detection. The system changes the playback speed of exercise videos according to the user's actual exercise intensity, making the content adaptive rather than static, which resolves the contradiction between personalization and complexity by using dynamic parameter adjustment instead of complex content generation
Solution Approach 2:
The system changes the reproduction rate parameter of exercise content based on detected exercise amount. By adjusting this single parameter (playback speed) rather than changing the entire content structure, the system achieves personalization while maintaining relative simplicity in implementation
2Reliability
If exercise contents are reproduced without considering user health information, then the system is simpler to operate, but incorrect exercise routing is provided to users
Solution Approach 1:
The system collects user health information (age, weight, height) in advance before the exercise session begins. This preliminary data collection enables accurate exercise routing determination without adding complexity during the actual exercise operation, as the routing logic is pre-configured based on the user's physical characteristics
Solution Approach 2:
The system continuously detects exercise amount during the workout and provides feedback by adjusting the reproduction rate accordingly. This closed-loop feedback mechanism ensures reliable exercise routing by constantly monitoring and adapting to the user's actual exercise intensity, matching the prescribed exercise level
3Productivity
If the reproduction rate of exercise content is adjusted according to exercise amount, then user engagement is enhanced, but the system requires more complex control mechanisms
Solution Approach 1:
The system automatically detects exercise amount using built-in sensors and self-adjusts the reproduction rate without requiring manual user input or complex external control. The exercise content adapts itself to the user's performance, achieving enhanced productivity through automated self-regulation rather than complex external control mechanisms

AI summary
A display method and a multimedia apparatus applying the same are provided. The display method includes acquiring exercise information of a user, transmitting the exercise information to a server, receiving from the server a transport stream including video data in which a screen is changed at a rate corresponding to the exercise information, and displaying the video data by processing the transport stream. Therefore, the multimedia apparatus provides active multimedia exercise content to the user using exercise information and physical information of the user.
