Station Sorting Matrix Interface for Broadcast Receivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sorting and managing television and radio stations in broadcast receivers are time-consuming and prone to errors, especially when dealing with large numbers of stations, as they require manual interchange of stations using methods like bubble sort, which can be confusing for users.
Innovation Solution
A method that displays stations in a matrix-type list with input fields for desired program location or station memory numbers, includes features like automatic presorting, shifting, and deletion options, and uses visual cues for allocated numbers, allowing users to efficiently organize and store stations in a desired order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual interchange method (bubble sort) is used to sort stations, then stations can be sorted according to desired order, but the process becomes time-consuming and error-prone when dealing with large numbers of stations
Solution Approach 1:
The station list is divided into individual rows displayed in a table format, with each station occupying a separate line. This segmentation allows users to visually scan and identify stations more easily, and to make selective changes without having to manually interchange stations one by one through complex sorting algorithms.
Solution Approach 2:
The system automatically performs preliminary sorting of stations before presenting them to the user for manual adjustment. This preliminary organization reduces the initial disorder in the station list, so users start with a partially sorted list rather than a completely unsorted one, significantly reducing the time and effort needed for final sorting.
2Ease of operation
If manual interchange method is used for sorting stations, then sorting can be achieved, but user complexity and difficulty increase especially with large numbers of stations
Solution Approach 1:
The sorting interface is transformed from a linear or hierarchical structure into a two-dimensional table with rows and columns. Stations are displayed in rows with their parameters in columns, allowing users to visually compare stations across multiple attributes simultaneously and make sorting decisions based on a broader perspective rather than sequential comparisons.
Solution Approach 2:
The table structure serves as an intermediary between the raw station data and the user's sorting decisions. Instead of directly manipulating station positions through complex interchange operations, users interact with the table interface which mediates the sorting process by providing visual cues, automatic sorting assistance, and simplified selection mechanisms.
3Productivity
If automatic station search stores stations in found order, then storage is simple and fast, but stations are not in user-desired order
Solution Approach 1:
The system performs automatic sorting of stations immediately after they are stored from the search results. This preliminary sorting action organizes stations according to predetermined criteria (such as frequency, channel number, or other parameters) before the user needs to access or adjust them, so stations are both quickly stored and pre-organized without requiring separate manual sorting steps.

AI summary
In a method for sorting and storing stations in a television or radio broadcasting set, the received stations are firstly represented in an arbitrary order in a matrixlike list or table on a display device. An input field into which a user inputs a program location number is represented for each station. The input may be effected by directly inputting one or more numerals, or be selecting a number from a list of available program location numbers. Selection fields whose selection brings about a deletion of the respective station or a shift to the end of the list may additionally be represented. Once the input or selection fields have been filled in or selected, the stations are sorted in accordance with the inputs. The sorted list is then stored.
