Electronic Device Channel Update via Area-Based Database Lookup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile-enabled electronic devices face challenges in receiving accurate channel information when users move to different areas or experience weak signal strength, leading to disrupted TV services due to the need for time-consuming channel scans.
Innovation Solution
The electronic device identifies area changes and signal strength conditions, allowing it to provide a preconfigured channel list without scanning, reducing power consumption and standby time by preventing unnecessary location searches and automatically switching to compatible channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a channel scan is performed to update channel information when area changes, then the channel list accuracy is improved, but the time consumption and power consumption increase
Solution Approach 1:
The electronic device stores channel information from multiple areas in advance in its memory. When the device detects an area change, it can immediately retrieve the pre-stored channel list for the new area without performing a time-consuming channel scan, thus resolving the contradiction between accuracy and time consumption
Solution Approach 2:
The device changes the parameter of channel information retrieval from real-time scanning to database lookup based on area identification. By identifying the current area and selecting the corresponding pre-stored channel list, the system achieves fast and accurate channel updates without scanning
2Measurement precision
If a channel scan is performed to update channel information when area changes, then the channel list accuracy is improved, but the power consumption increases
Solution Approach 1:
Channel information for multiple areas is stored in advance in the device's memory. When area change is detected, the device retrieves pre-stored channel lists instead of performing energy-intensive channel scans, thereby maintaining accuracy while reducing power consumption
Solution Approach 2:
The device extracts only the necessary channel information for the detected area from its stored database, rather than performing a full channel scan. This selective retrieval approach maintains channel list accuracy while significantly reducing power consumption
3Measurement precision
If location search is performed continuously to detect area changes, then the area change detection accuracy is improved, but the power consumption increases
Solution Approach 1:
Instead of continuous location searching, the device performs periodic area detection at relevant moments (such as when channel updates are needed or at scheduled intervals). This periodic approach maintains detection accuracy while reducing power consumption compared to continuous monitoring
