Channel Switching Prediction Using Correlation Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in switching to frequently watched TV channels without memorizing channel numbers and with minimal operation clicks, as existing remote controllers require multiple button presses or memory of channel numbers due to the lack of efficient channel-switching functionality.
Innovation Solution
A method and device that predicts the next channel to be switched to based on a current channel using a channel-switching correlation table, allowing users to switch to frequently watched channels with fewer operations by displaying and switching to candidate channels through a data transmission unit when a channel-switching signal is received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users operate up/down or +/â buttons to switch channels in sequence, then channel switching is achieved, but the number of operation clicks increases significantly when favorite channels are distributed discretely
Solution Approach 1:
The system pre-arranges favorite channels in a predetermined sequence and stores this sequence in memory. When a channel switching signal is received, the system automatically switches to the next favorite channel in the sequence without requiring users to manually input channel numbers or press multiple buttons, thus reducing operation clicks and switching time
Solution Approach 2:
The system automatically manages the channel switching process by detecting the current channel, comparing it with the stored favorite channel sequence, and autonomously switching to the appropriate favorite channel. This self-service mechanism eliminates the need for users to manually search through channels or remember channel numbers
2Ease of operation
If users input channel numbers directly, then direct channel switching is achieved, but users must remember channel numbers which increases operation complexity
Solution Approach 1:
The system automatically detects the current channel being viewed and autonomously switches to the corresponding favorite channel from the predetermined sequence without requiring users to input channel numbers. This eliminates the need for users to remember channel numbers while still achieving direct channel switching
3Ease of operation
If recall key switches between two channels, then simple operation is achieved, but the functionality is insufficient for users who need to access multiple favorite channels
Solution Approach 1:
The system stores a predetermined sequence of multiple favorite channels (not just two) and can switch between any of them based on the current channel detection. This multi-functional capability maintains the simplicity of the recall function while significantly expanding the versatility to support multiple favorite channels
Solution Approach 2:
The system pre-arranges multiple favorite channels in a sequence and stores this information in memory. When a channel switching signal is received, it automatically identifies the current channel and switches to the appropriate favorite channel from the pre-arranged sequence, providing both simplicity and versatility

AI summary
In a method for controlling channel-switching, a current channel is displayed through a display unit. A channel-switching correlation table is looked up to obtain at least one candidate channel, which is predicted to be watched after the current channel. The current channel is switched to the at least one candidate channel when a channel-switching signal is received, such that the display unit displays the at least one candidate channel. The present invention also discloses a device for controlling channel-switching and a non-transitory computer-readable storage medium for storing the method for controlling channel-switching.
