Display Apparatus Automatic HD Channel Selection

Solution Overview

Problem

Conventional display apparatuses require users to manually select and store HD broadcasting channels, making it inconvenient to watch only channels associated with a predetermined broadcasting format, such as HD broadcasting.

Innovation Solution

A display apparatus with a tuner, broadcasting format selection unit, and controller that analyzes sequence headers or PSIP data to automatically display channels corresponding to a selected broadcasting format, such as HD, on the display unit, allowing users to watch only HD channels without separate channel selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users manually select and store HD broadcasting channels, then the display apparatus can display HD channels, but the ease of operation deteriorates because users must perform separate channel selection and storage operations

Engineering Contradiction:

ImproveHD channel display capabilityVSAvoidchannel selection convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The display apparatus automatically identifies and displays HD broadcasting channels by analyzing broadcasting format information from sequence headers or PSIP data, eliminating the need for users to manually select and store channels. The system serves itself by autonomously determining which channels match the selected broadcasting format and displaying them without user intervention.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary analysis of broadcasting format information from sequence headers or PSIP data to pre-identify HD channels before the user needs to watch them. This preliminary action allows the display apparatus to automatically configure and display HD channels without requiring users to perform separate selection operations.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If users manually store each HD channel as desired channel, then HD channels can be displayed, but the time required for channel selection increases

Engineering Contradiction:

ImproveHD channel display capabilityVSAvoidchannel selection time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The display apparatus automatically identifies and displays HD broadcasting channels by analyzing broadcasting format information from sequence headers or PSIP data, eliminating the need for users to manually select and store channels. The system serves itself by autonomously determining which channels match the selected broadcasting format and displaying them without user intervention.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary analysis of broadcasting format information from sequence headers or PSIP data to pre-identify HD channels before the user needs to watch them. This preliminary action allows the display apparatus to automatically configure and display HD channels without requiring users to perform separate selection operations.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the display apparatus automatically displays channels based on broadcasting format, then the ease of operation improves, but the device complexity increases due to additional analysis functions

Engineering Contradiction:

Improvechannel selection convenienceVSAvoidbroadcasting format analysis capability

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The display apparatus utilizes existing broadcasting signal processing functions to simultaneously achieve multiple objectives: signal reception, format analysis, and channel selection. By making the existing system multi-functional, the patent avoids adding separate dedicated hardware for format analysis, thereby limiting the increase in device complexity while achieving automatic channel display based on broadcasting format.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The controller acts as an intermediary that processes broadcasting format information from sequence headers or PSIP data and translates it into channel selection actions. This intermediary function integrates the format analysis and channel selection processes, avoiding the need for separate dedicated hardware systems and thus limiting the increase in device complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A display apparatus and a control method thereof is provided in which channels corresponding to a predetermined broadcasting format are displayed on a display unit even though they are not separately selected by a user as desired channels. A display apparatus includes a display unit to display a picture thereon, and a tuner to select a channel, a broadcasting format selection unit to select a predetermined broadcasting format, a signal receiver to receive information about the broadcasting format, and a controller to control the tuner to allow the channel corresponding to the broadcasting format to be displayed on the display unit when the broadcasting format is selected through the broadcasting format selection unit.
