Favorite Channel List Generation via Program-Advertisement Transition Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating a favorite channel list on TV remote controls are inefficient as they rely on a predetermined time for adding channels, which can result in either missing favorite channels or storing indiscriminate channels due to time settings being too long or too short.
Innovation Solution
A method and device that utilize a processor to add a channel to a favorite channel list when the TV signal switches from a program to an advertisement, eliminating the need for a time-based condition, and allowing for channel management based on program and advertisement transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a predetermined time threshold is used to add channels to the favorite list, then channels watched by users can be automatically added, but the accuracy of identifying truly favorite channels deteriorates due to difficulty in determining the appropriate time length
Solution Approach 1:
The patent changes the parameter used for channel selection from time duration to content type transition. Instead of measuring how long a user watches a channel, the system detects when the channel content switches from program to advertisement, using this transition event as the criterion for adding to the favorite list. This parameter change resolves the contradiction by providing an objective, easily detectable marker that accurately identifies user interest without requiring arbitrary time thresholds.
2Quantity of substance
If the predetermined time is set too long, then more channels can be captured, but favorite channels may be missed due to user disinterest; if set too short, then channel selection becomes indiscriminate
Solution Approach 1:
The system uses the television signal itself to provide the selection criterion. By detecting the program-to-advertisement transition within the signal content, the system automatically identifies channels that are currently being watched with meaningful engagement. This self-service approach eliminates the need for external time parameter configuration and provides accurate, context-aware channel selection.
3Extent of automation
If time-based conditions are used for generating the favorite channel list, then automatic channel addition is achieved, but the system complexity increases due to difficulty in determining and configuring the predetermined time
Solution Approach 1:
The patent extracts the time parameter from the channel selection process and replaces it with content transition detection. By removing the time-based condition and substituting it with program-to-advertisement transition detection, the system eliminates the complexity of time configuration while maintaining automatic channel addition functionality. The selection criterion is now embedded in the signal content itself rather than requiring external parameter settings.

AI summary
A method for generating a favorite channel list, where a device for generating the favorite channel list includes a receiver and a processor, is disclosed. The method includes receiving a signal of a first channel of a television signal by the receiver; clearing channels stored in the favorite channel list by the processor before the receiver receives the television signal according to the television signal; and adding the first channel to the favorite channel list by the processor when the signal of the first channel is switched from a first program to an advertisement.
