Solution Overview

Problem

Display devices lack an efficient method to provide users with easy access to previously viewed content information from various sources, including terrestrial broadcasting, network providers, and external devices, without overwhelming users with irrelevant content.

Innovation Solution

A display device and method that generates and displays a previously-viewed-contents list, storing content information and source details when content is played for a predetermined time, allowing users to easily access preferred content through user input and customizable list formats, including thumbnails.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a display device provides content information from multiple different sources (terrestrial broadcasting, network providers, external devices), then the variety and completeness of content history increases, but the complexity of managing and organizing this diverse information increases

Engineering Contradiction:
Improvecontent source compatibilityVSAvoidinformation management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display device implements a universal content history management system that handles multiple content sources (terrestrial broadcasting, network providers, external devices) through a single integrated previously-viewed-contents list. This multi-functional approach allows the device to universally manage diverse content types without requiring separate management systems for each source, thereby reducing overall system complexity while maintaining adaptability across all content providers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of information

If the display device stores detailed content information including source information for all played content, then the completeness of content history increases, but the storage requirements and data processing load increase

Engineering Contradiction:
Improvecontent history completenessVSAvoidstored data quantity
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The system extracts and stores only essential content information elements in the previously-viewed-contents list, specifically content identifiers and source information. By selectively extracting only the most critical data elements needed for content retrieval and user recognition, the system maintains complete content history tracking while minimizing the quantity of stored data and reducing processing loads.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the display device provides a comprehensive previously-viewed-contents list with all content details, then the user's ability to find preferred content improves, but the interface complexity and user cognitive load increase

Engineering Contradiction:
Improvecontent retrieval easeVSAvoidinterface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The previously-viewed-contents list is segmented into distinct, organized entries where each content item is presented as a separate unit with clear identification. This segmentation allows users to easily scan and identify preferred content without being overwhelmed by a continuous stream of information, thereby improving content retrieval ease while keeping the interface simple and manageable.

Inventive Principle:
Principle #1Segmentation

AI summary

A display device and a method of providing a contents list are provided. An apparatus/method is provided. The method includes: playing contents; determining whether the contents are played more than a predetermined time; when the contents are played more than the predetermined time, storing contents information including source information on the contents in a previously-viewed-contents list; and displaying the stored previously-viewed-contents list according to a user's input.
