Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of existing TV remote control operations, particularly channel switching, poses difficulties for elderly users due to dense key functions and visual attenuation, making it inconvenient for them to navigate and store specific channels.
Innovation Solution
A signal processing method and apparatus that decodes control signals, compares them with preset instructions, and generates execution instructions for channel storage, change, sequence adjustment, and deletion, allowing users to store and switch channels more intuitively by simplifying the operation of channel management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple channel switching functions are integrated into a single remote control, then the functionality and versatility of the remote control is improved, but the complexity of operation and difficulty of use increases for elderly users
Solution Approach 1:
The patent segments the channel storage and switching functions from the numerical key input functions. By separating these functions into distinct operational modes (storage mode vs. switching mode), the remote control reduces the cognitive load and operational complexity for elderly users while maintaining full functionality.
Solution Approach 2:
The remote control dynamically changes its operational behavior based on the current mode. When in storage mode, it accepts multi-digit channel numbers; when in switching mode, it uses simplified channel navigation. This dynamic adaptation allows a single device to serve multiple purposes without permanently increasing operational complexity.
2Adaptability or versatility
If all TV channels are made accessible through the remote control, then the completeness of channel access is improved, but the time required for channel switching and the burden on users increases
Solution Approach 1:
The patent implements preliminary action by allowing users to store frequently watched channels in advance. Once channels are stored in the remote control's memory, they can be quickly accessed without re-entering the full channel number each time, significantly reducing channel switching time for repeated operations.
Solution Approach 2:
The patent extracts the most commonly accessed channels from the complete channel list and stores them separately in the remote control's memory. This extraction creates a simplified subset of channels that can be quickly navigated, separating the frequent use case from the complete channel list.
3Quantity of substance
If numerical keys for channel selection are made dense to fit more channels, then the quantity of channel options is improved, but the visual discernibility and ease of key identification deteriorates for users with visual attenuation
Solution Approach 1:
The patent introduces an intermediary layer between the physical keys and the channel selection function. Instead of directly mapping each channel to a separate key, the system uses a two-step process: first selecting a channel using simplified navigation (previous/next buttons), then confirming the selection. This intermediary navigation layer reduces the need for dense key layouts.
4Speed
If rapid key pressing is required within a time limit for channel switching, then the speed of operation is improved, but the reliability of operation decreases for users with slower response times
Solution Approach 1:
The patent uses periodic action by implementing a countdown timer that provides continuous feedback to the user. The timer counts down from a preset time limit, allowing users to understand how much time remains. This periodic feedback mechanism helps users pace their key pressing actions and improves reliability by making the time constraint explicit rather than implicit.

AI summary
There are disclosed a signal processing method, a signal reception processing apparatus and a TV system, wherein the signal processing method comprises: receiving a control signal and decoding said control signal; comparing a signal instruction obtained from the decoding with preset instructions and generating an execution instruction corresponding to the matched preset instruction, wherein said preset instructions include a channel storage instruction and a channel change instruction; and performing corresponding execution actions according to the execution instruction. In the signal reception processing apparatus and the TV system based on the above method, specific channels are stored by decoding the control signal, and thus by storing specific channels, the aged can perform operations only on these specific TV channels instead of all TV channels when watching TV programs, and therefore they can watch TV program conveniently.
