Broadcasting Channel Selection via PSIP Title Matching

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional broadcasting systems require users to manually search through channels by number, making it difficult to quickly find desired channels if the channel number is not remembered.

Innovation Solution

A broadcasting system with an input unit featuring character set buttons and a broadcasting reception device that uses PSIP data to load and display channels by title, allowing users to select channels based on station titles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If users manually search through channels by number using conventional methods, then the system maintains simple operation structure, but users cannot quickly find desired channels when channel numbers are not remembered

Engineering Contradiction:

Improvechannel selection speedVSAvoidoperation complexity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent introduces PSIP data as an intermediary that contains broadcasting station title information. This mediator enables the system to match user input (character strings) with channel information without requiring direct numerical channel selection, thereby speeding up channel acquisition while maintaining operational simplicity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical channel number input system with a character-based title matching system. Users input characters that match broadcasting station titles stored in PSIP data, and the system automatically identifies and switches to the corresponding channel, eliminating the need for manual channel number entry and sequential channel scanning

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of time

If users check all broadcasting channels by pushing channel skip button, then the system maintains simple channel switching mechanism, but users waste time finding desired channels

Engineering Contradiction:

Improvechannel search timeVSAvoidchannel selection efficiency

Core Design Contradiction:

Loss of timeVSProductivity

Solution Approach 1:

The patent implements preliminary action by pre-storing broadcasting station title information in PSIP data before the user needs to select a channel. This allows the system to quickly match user input against pre-organized title data rather than sequentially scanning through all channels, significantly reducing channel search time

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback by displaying matching broadcasting station titles when users input characters, allowing users to confirm the correct channel before switching. This feedback mechanism ensures accurate channel selection while maintaining rapid search capability

Inventive Principle:

Principle #23Feedback
