Portable Terminal Signal Control for TV Recording Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for presetting TV program recordings on portable information terminals are complex and time-consuming, requiring users to manually input G codes or browse through extensive TV program lists on screens, making it inefficient for offline access and unattended recording.
Innovation Solution
A portable information terminal apparatus that generates and transmits signals to acquire, display, and preset TV program information for unattended recording, using infrared or radio waves, allowing users to manage program information offline without manual input, enabling efficient recording setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually input G codes or browse TV program lists on PDA screens, then TV program recording can be preset, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent introduces an intermediary device (such as a remote control or automated interface) that mediates between the user and the VTR system. This intermediary automatically transmits the G code to the VTR based on user selection, eliminating the need for manual G code input and significantly reducing presetting time while maintaining ease of operation.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the VTR with program information and G codes before the user needs to preset recording. The VTR is pre-loaded with electronic program guide data and corresponding G codes, so when a user selects a program, the recording parameters are already prepared and can be instantly applied without manual input.
2Loss of information
If users browse through extensive TV program lists on PDA screens to find desired programs, then program information can be accessed, but the search process becomes time-consuming
Solution Approach 1:
The patent replaces the mechanical browsing system (manual scrolling through program lists on PDA screens) with an automated information retrieval system. The VTR's electronic program guide and automated search functions substitute for manual browsing, allowing users to quickly find desired programs through automated queries and filtered results, dramatically reducing search time while maintaining full access to program information.
