Automatic Favorite Channel Retrieval Using Viewing Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing universal remote control devices require complex user programming for favorite channel functionality, which is time-consuming and inefficient, and do not adapt to changing user preferences without manual intervention.
Innovation Solution
A remote control device with a microcontroller that automatically tracks and stores favorite channels based on user viewing habits, using a favorite key to tune to preferred channels without manual reprogramming, and updates rankings dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a universal remote control device uses manual programming for favorite channel functionality, then the device can recall specific channels, but the programming process is time-consuming and complex for users
Solution Approach 1:
The remote control device automatically monitors channel changes and viewing duration without user intervention. The microcontroller tracks which channels the user spends time watching and autonomously designates them as favorite channels, eliminating the need for manual programming while ensuring accurate favorite channel recall.
Solution Approach 2:
The device pre-identifies favorite channels by monitoring viewing patterns before the user needs to recall them. The microcontroller continuously tracks channel viewing duration and automatically populates the favorite channel list in advance, so when the user presses the favorite channel button, the channels are already identified and ready for recall.
2Reliability
If the remote control device manually programs favorite channels, then specific channels can be recalled, but any change in user preference requires manual reprogramming
Solution Approach 1:
The favorite channel list is dynamic rather than static. The microcontroller continuously monitors channel viewing duration and automatically updates the favorite channel list based on current user behavior. When a user spends sufficient time watching a channel, it is automatically added to the favorite list, and the system adapts to changing preferences without requiring manual reprogramming.
Solution Approach 2:
The device implements feedback by monitoring user channel selection behavior and using this information to automatically update the favorite channel list. The microcontroller tracks viewing duration and uses this feedback to dynamically adjust which channels are designated as favorites, ensuring the system continuously adapts to evolving user preferences.
3Ease of operation
If the remote control device uses channel up/down buttons to return to initial programs, then the function can be achieved, but the user may have to increment through many channels causing frustration and loss of viewing time
Solution Approach 1:
The device pre-identifies and stores the initial program channel information in memory. When the user presses the favorite channel button, the microcontroller retrieves the stored channel information and immediately switches to that channel, bypassing the need to increment through multiple channels and significantly reducing the time to return to the original program.

AI summary
A consumer electronic device tracks the current channel to which the electronic consumer device is tuned. The consumer electronic device determines an amount of time that the current channel remains unchanged. Based at least in part on this amount of time, the consumer electronic device determines whether the current channel should be stored as a favorite channel. When the consumer electronic device subsequently receives a favorite channel command, the consumer electronic device is caused to tune to the favorite channel that is currently stored in memory. Changing user preferences are thus automatically accommodated without manual intervention, resulting in an effortless user interface.
