One-Seg Reception Device Tuning via Network-Acquired Station Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Arbitrary one-seg broadcasting requires time-consuming channel scanning to update tuning tables when a user moves, as the broadcasting area is limited, leading to a need for quick presentation of receivable one-segment broadcasts.
Innovation Solution
A reception device and method that acquires station information, selects a tunable station, and performs tuning control to quickly update the service based on the transmission frequency, allowing for rapid adaptation to new broadcasting areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel scanning is performed to update tuning information when a user moves, then the reception device can present receivable broadcasts, but the process takes an enormous amount of time
Solution Approach 1:
The reception device performs preliminary actions by acquiring and storing transmission frequency information in advance through network connection before the user moves. This allows the device to quickly update tuning information without performing time-consuming channel scanning, thereby resolving the contradiction between reliability of presenting receivable broadcasts and time consumption.
2Adaptability or versatility
If tuning information is updated by scanning all 13 segments of each physical channel, then complete broadcasting services are acquired, but the process becomes extremely time-consuming
Solution Approach 1:
The invention extracts only the necessary transmission frequency information from the broadcast signal through network connection, rather than scanning all 13 segments of each physical channel. This selective extraction maintains adaptability to various broadcasting services while dramatically reducing the time required for updating tuning information.
3Adaptability or versatility
If the reception device stores detailed tuning information for multiple segments, then it can adapt to different broadcasting areas, but the device complexity increases
Solution Approach 1:
The invention uses network connection as an intermediary to acquire and store transmission frequency information. This intermediary approach simplifies the device's internal complexity by leveraging external network resources while maintaining the ability to adapt to different broadcasting areas through stored frequency data.
