Portable Terminal Multimedia Broadcasting Control During Vehicle Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for processing digital broadcasting data on portable terminals while driving a vehicle pose a safety risk due to user distraction, as they do not effectively manage multimedia broadcasting services during vehicle operation, potentially leading to accidents.
Innovation Solution
A method is implemented in a portable terminal with a navigation module that recognizes vehicle driving mode, acquires vehicle driving information, and applies specific vehicle driving functions to process and output multimedia broadcasting data, including options to turn off services or adjust settings based on speed and dangerous areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multimedia broadcasting data is outputted while driving a vehicle, then the user can enjoy digital broadcasting services during movement, but the user may become distracted and cause accidents
Solution Approach 1:
The system dynamically adjusts multimedia output based on vehicle speed. When the vehicle is stationary or moving slowly, both video and audio outputs are enabled. When the vehicle exceeds a predetermined speed threshold, the system automatically disables video output and switches to audio-only mode, thereby adapting the service delivery to the driving conditions and reducing distraction risks
Solution Approach 2:
The system changes the operational parameters of multimedia broadcasting based on vehicle motion state. By detecting vehicle speed and movement status, the system modifies output parameters (video on/off, audio on/off) to match the safety requirements of different driving scenarios, allowing service availability while managing harm through parameter adjustment
2Ease of operation
If video and audio outputs are continuously enabled during vehicle operation, then the user experience is maintained, but the safety risk increases
Solution Approach 1:
The system implements a feedback mechanism where the vehicle's motion state (speed, movement status) is continuously monitored and fed back to the multimedia control system. Based on this feedback, the system automatically adjusts output settings - maintaining full user experience when safe, and switching to restricted mode when safety risks are detected, thus balancing experience quality with driving safety
3Reliability
If the system automatically adjusts multimedia output based on vehicle speed, then safety is improved, but the system complexity increases
Solution Approach 1:
The vehicle's existing navigation system serves multiple functions: it provides navigation services and simultaneously acts as the control mechanism for multimedia broadcasting. By reusing the navigation system's speed detection and control capabilities, the patent avoids adding separate sensors and control circuits, thereby improving safety through automatic adjustment while minimizing the increase in system complexity

AI summary
Disclosed is a method for processing a multimedia broadcasting in a portable terminal having a navigation module, while a vehicle is being driven. The method includes steps of: proceeding to a vehicle driving mode, if it is recognized that the vehicle is currently being driven when the multimedia broadcasting data is outputted; confirming at least one vehicle driving function set as the vehicle driving mode in the vehicle driving mode and driving navigation module, and then acquiring vehicle driving information; and reflecting the acquired vehicle driving information in the vehicle driving function and then outputting the multimedia broadcasting data after applying the vehicle driving function to the multimedia broadcasting data.
