Channel List Management via Deleted Data Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display devices are inefficient in managing a large number of channels and program information, as users have to manually delete unwanted channels each time they browse, leading to inconvenience and inefficiency.
Innovation Solution
A video display device and method that allows users to store deleted channel/program information in a data storage, enabling users to restore or permanently delete it with user-selectable options, using a user interface and control processor to manage lists of pre-selected and deleted information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If users manually delete unwanted channels each time they browse, then the number of displayed channels is reduced, but user convenience and efficiency deteriorate
Solution Approach 1:
The system performs preliminary action by automatically storing deleted channel information in a database before the user needs to restore it. This prevents the need for users to manually re-search and re-add channels, as the deletion history is preserved in advance for quick restoration.
Solution Approach 2:
The system creates a copy of the deleted channel information and stores it in a database. This copy allows users to restore channels without affecting the original channel list structure, enabling efficient management by working with copies rather than permanently altering the main channel list.
2Reliability
If users manually re-search for deleted channels to restore them, then channel information can be recovered, but time consumption increases
Solution Approach 1:
The system performs preliminary action by automatically capturing and storing deleted channel information in a database at the moment of deletion. This eliminates the need for time-consuming re-search operations, as the channel data is already preserved and readily available for immediate restoration.
Solution Approach 2:
The system provides feedback to users by displaying deleted channel information in a dedicated window, allowing users to see what has been deleted and restore it with a single command. This feedback mechanism eliminates the uncertainty and time associated with searching for deleted channels.
3Quantity of substance
If deleted channel information is permanently removed, then storage space is freed, but user ability to restore channels is lost
Solution Approach 1:
The system implements discarding and recovering by storing deleted channel information in a database rather than permanently removing it. Users can choose to restore channels when needed, and the system manages the storage efficiently by only keeping deleted information for a reasonable period, balancing storage capacity with restoration flexibility.

AI summary
A display device and method of managing a list of channel information in a video display device are provided. The display device includes the steps of displaying a first window including a first list of pre-selected channel and/or program information, storing at least one channel and/or program information deleted from the first window to a data storage, displaying a second window including a second list of deleted channel and/or program information stored in the data storage, and selectively restoring a channel and/or program information selected from the second list to the first list.
