Solution Overview

Problem

Current digital display devices, such as smart TVs, face challenges in efficiently accessing and managing pre-stored content, with complex and time-consuming processes for retrieving recorded content and limited user-friendly options for selecting desired content.

Innovation Solution

A digital display device equipped with a remote controller interface, network interface, processor, memory, and main controller that allows for efficient storage, retrieval, and processing of content, including the use of a virtual channel for accessing pre-stored content and optimizing storage based on internal and external memory status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If content is manually or automatically stored in memory, then content storage capability is improved, but user adoption is low due to complicated and time-consuming access process

Engineering Contradiction:
Improvecontent storage capabilityVSAvoidcontent access process
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The system pre-processes and organizes content during storage by assigning channel numbers and creating structured indexes. When users want to access content, the pre-organized structure allows direct retrieval without complex navigation, resolving the contradiction between storage capability and access ease

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary indexing system that maps user-friendly channel numbers to stored content locations. This intermediary layer simplifies the access process by providing a straightforward interface between user input and content retrieval, eliminating the need for complicated search operations

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If multiple pieces of content are stored in memory, then content variety is improved, but access time increases due to complex retrieval processes

Engineering Contradiction:
Improvecontent varietyVSAvoidcontent access time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent segments the content library into organized channels with distinct identifiers. Each channel represents a categorized group of content, allowing the system to retrieve specific content by directly accessing the relevant channel segment rather than searching through all stored content, thus reducing access time while maintaining content variety

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Content is pre-segmented into channels and indexed during the storage process. This preliminary organization creates a ready-to-access structure that enables rapid retrieval of specific content without requiring time-consuming search operations, resolving the time loss associated with accessing varied content

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a service for selectively providing desired content among many pieces of content is implemented, then user convenience is improved, but device complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoidcontent management system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent employs an intermediary channel assignment system that acts as a simple mediator between user input and content delivery. This intermediary layer provides user convenience through straightforward channel-based access while keeping the underlying complexity of content management hidden, thus improving ease of operation without significantly increasing perceived device complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A digital display device and a method for controlling the same are disclosed. The method of controlling a digital display device connected to at least one network and at least one memory includes receiving content (e.g., a TV program, etc.) over the at least one network, calculating memory capacity of an internal or external memory, storing the received content (e.g., a TV program, etc.) in the internal or external memory according to the calculated result, accessing the internal or external memory if a specific channel is selected, extracting the content (e.g., a TV program, etc.) stored in the accessed internal or external memory, and outputting video data and audio data corresponding to the extracted content (e.g., a TV program, etc.).
