Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals experience unnecessary power consumption due to always-active functions related to supplementary information, which can lead to reduced user guidance when needed.
Innovation Solution
A method and apparatus for managing broadcasts in portable terminals that adaptively control broadcasting receiver functions based on the terminal's environment, including determining moving speed and field strength to optimize power usage and function activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functions related to supplementary information are always activated, then user guidance is always available, but power consumption increases unnecessarily
Solution Approach 1:
The patent applies dynamics by making the system adaptable to different operating conditions. The controller dynamically adjusts whether to activate supplementary information functions based on real-time detection of terminal movement state (moving vs. stationary) and signal field strength, rather than maintaining a fixed always-on or always-off state
Solution Approach 2:
The patent changes operational parameters (function activation state) based on detected environmental conditions (movement speed and field strength). When the terminal is moving or field strength is weak, the system changes the parameter to deactivate supplementary functions, thereby reducing power consumption while maintaining guidance availability when conditions are favorable
2Use of energy by moving object
If functions related to supplementary information are inactivated to reduce power consumption, then power usage decreases, but user guidance is unavailable when needed
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring terminal movement state and signal field strength, then using this feedback information to control the activation state of supplementary information functions. The system receives feedback from sensors and environmental conditions, processes this information, and adjusts function activation accordingly to balance power consumption and guidance availability
Solution Approach 2:
The system performs self-service by automatically determining whether to activate or deactivate supplementary information functions based on detected conditions, without requiring manual user intervention. The controller autonomously evaluates movement state and field strength, then independently decides on function activation, enabling the system to serve itself in optimizing power usage while maintaining necessary functionality
3Reliability
If the broadcasting receiver continuously monitors signal quality and adjusts frequency, then reception reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the control logic into distinct operational branches based on detected conditions. The controller segments the decision-making process into separate pathways: one for when the terminal is moving or field strength is weak (deactivate functions), and another for when the terminal is stationary and field strength is sufficient (activate functions). This segmented approach simplifies the overall control logic while maintaining reliable reception

AI summary
A method and an apparatus for managing a broadcast for a portable terminal receiving supplementary information related to the broadcast are provided. The method includes tuning a broadcasting receiver of the portable terminal to a frequency from among a plurality of frequencies of a broadcasting channel, receiving, by the broadcasting receiver, a broadcasting signal on the tuned frequency, determining whether a moving speed of the portable terminal is equal to or more than a predetermined speed when a broadcasting receiver is tuned to the frequency and is receiving a broadcasting signal, measuring a field strength of the received broadcasting signal when the moving speed of the portable terminal is equal to or greater than the predetermined speed, and controlling the broadcasting receiver to be tuned to another frequency in order to receive the broadcasting signal of the broadcasting channel when the measured field strength is less than a predetermined threshold.
