Automatic Channel Toggling with Priority-Based Trigger Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing television channel switching methods are inadequate for managing multiple channels of interest simultaneously, particularly when there are three or more channels, as they require manual intervention and are not efficient in handling conflicts or overlapping broadcasts.
Innovation Solution
A device and method that allow users to input and prioritize multiple television channels, with options for automatic channel switching based on predetermined criteria such as commercial detection, vocal cues, and time intervals, using a processor to manage channel toggling and display the highest priority channel not airing a commercial.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual channel switching using remote control buttons is used, then the viewer can switch between two channels, but the method becomes inefficient and impractical when there are three or more channels of interest
Solution Approach 1:
The system performs preliminary actions by pre-configuring channel lists, priority levels, and toggle triggers before viewing. The processor is programmed with multiple channels of interest and their priority rankings, enabling automatic channel switching without manual intervention during viewing. This resolves the contradiction by preparing the channel management structure in advance, making operation simple while handling complex multi-channel scenarios.
Solution Approach 2:
The system enables self-service by automatically monitoring the current channel for toggle triggers (commercials, vocal cues, time intervals) and autonomously switching to the next highest priority channel when triggers are detected. This eliminates the need for manual remote control operation, resolving the contradiction between ease of operation and device complexity by making the system self-managing.
2Extent of automation
If automatic channel switching based on toggle triggers is implemented, then manual intervention is minimized, but the system complexity increases due to multiple detection criteria
Solution Approach 1:
The system segments the automatic channel switching function into distinct toggle trigger types: commercial detection, vocal cue detection, and time interval-based triggers. Each trigger type operates independently with its own detection mechanism, allowing the system to achieve high automation while managing complexity through functional segmentation. The processor evaluates each trigger type separately, switching channels based on whichever trigger condition is met.
3Measurement precision
If multiple toggle trigger types are monitored simultaneously, then channel switching accuracy improves, but the processing requirements and system complexity increase
Solution Approach 1:
The system implements partial action by monitoring for toggle triggers in a prioritized sequence rather than evaluating all triggers simultaneously. The processor first checks for commercial detection triggers, then vocal cue triggers, and finally time interval triggers. This approach achieves accurate trigger detection by examining each trigger type thoroughly in turn, while managing processing power by avoiding redundant simultaneous evaluation of all trigger types.

AI summary
Systems and methods for toggling between television channels that appear on a display. A listing of channels is received from a user, with the channels being prioritized in an order of preference. One or more toggle types are also received from the user, with each toggle type further including a toggle trigger. In use, a channel is displayed on the display until a toggle trigger is detected. Once detected, the channel on the display is changed to another channel from the list of channels. This process may continue with the detection of another toggle trigger causing another changing of the displayed channel.
