Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image providing devices lack the capability to stably store received broadcast content, particularly in transitioning from analog to digital broadcasting, where robustness against external noises and high-definition image provision are essential.
Innovation Solution
An image providing device with a dual circuit board structure, where a first circuit board receives and processes broadcast signals, and a second circuit board, with a different operating system, stores the signals, enabling stable storage and processing of multiple broadcast signals through distinct interface units and processors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If broadcast content is stored in a single circuit board with limited storage space, then device complexity is reduced, but storage capacity and stability are insufficient
Solution Approach 1:
The device is divided into two separate circuit boards: a first circuit board (TV board) for receiving and processing broadcast signals, and a second circuit board (PC board) with large storage capacity for storing broadcast content. This segmentation allows each board to have specialized functions, increasing overall storage capacity while keeping individual board complexities manageable.
Solution Approach 2:
The patent combines two different circuit boards with different operating systems (first OS on TV board, second OS on PC board) into a single integrated device. This merging allows the device to leverage the processing capabilities of the TV board and the storage capabilities of the PC board, achieving both high storage capacity and functional complexity.
2Ease of operation
If multiple broadcast signals are processed simultaneously, then user convenience is improved, but interface unit complexity increases
Solution Approach 1:
The second interface unit on the PC board is designed to receive broadcast signals from multiple different first interface units simultaneously. This multi-functional capability allows the system to handle multiple broadcast signals through a single interface unit, improving user convenience while managing interface complexity through universal design.
3Reliability
If a single operating system is used on one circuit board, then system simplicity is maintained, but processing capability and storage stability are limited
Solution Approach 1:
The system is segmented into two independent operating systems: a first OS running on the TV board for broadcast signal processing and a second OS running on the PC board for content storage and management. This segmentation allows each OS to be optimized for its specific function, improving storage stability while distributing system complexity across separate modules.

AI summary
The present invention relates to an image providing device. The image providing device, according to one embodiment of the present invention, comprises: a first circuit board having a broadcast receiving unit for receiving a broadcast signal, a first processor for signal-processing the received broadcast signal, and a first interface unit for transmitting the signal-processed broadcast signal to a second circuit board if there is a broadcast storage input; and the second circuit board having a second interface unit for receiving the broadcast signal from the first interface unit, a storage unit for storing the received broadcast signal, and a second processor for controlling the second interface unit and the storage unit, wherein the second processor drives a second OS differing from a first OS driven in the first processor and executes an application on the basis of the second OS. Thus, received broadcast content can be stably stored.
