Display Apparatus Interleaving Pattern Frames for Non-Intrusive Data Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses lack the ability to efficiently provide 2D information embedded in video content, as QR codes are difficult to capture and interrupt the viewing experience due to their dynamic nature.
Innovation Solution
A display apparatus that interleaves pattern frames, such as black and white frames, between image frames, allowing a user terminal to photograph and identify the pattern information, which is then used to retrieve data related to the display apparatus from an external source, enabling easy access to information without interrupting the video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If QR codes are interleaved into video content, then information transmission capability is improved, but user ability to capture the QR codes deteriorates due to image changes
Solution Approach 1:
The video content is segmented into individual frames, and a specific frame (or specific regions within a frame) is designated to contain the QR code. This segmentation allows the QR code to be presented in a stable, captureable format while the rest of the video continues to play, resolving the contradiction between information transmission and captureability.
Solution Approach 2:
The QR code is prepared and embedded in advance within a specific video frame before the video is displayed. This preliminary action ensures that when the frame is displayed, the QR code is already in the correct position and state for capture, eliminating the issue of image changes making capture difficult.
2Loss of information
If QR codes are interleaved into video content, then information transmission capability is improved, but viewing experience deteriorates due to coverage of video parts
Solution Approach 1:
The QR code is placed in a specific local region of the video frame rather than covering the entire frame. This local placement allows the QR code to be visible and captureable while the rest of the video content remains visible and viewable, resolving the contradiction between information transmission and viewing experience.
Solution Approach 2:
The video frame is segmented into different functional regions: one region contains the QR code for information transmission, while other regions contain the video content for viewing. This segmentation allows both functions to coexist without mutual interference.
3Ease of operation
If pattern frames are interleaved between image frames, then information retrieval convenience is improved, but system complexity increases
Solution Approach 1:
Instead of creating a completely new complex system for information retrieval, the patent uses a copy of the existing video frame structure, designating one frame (or region) to contain the QR code. This copying approach leverages existing video playback infrastructure, minimizing additional system complexity while improving information retrieval convenience.

AI summary
A user terminal apparatus is disclosed. A user terminal apparatus according to various exemplary embodiments includes a communication unit which communicates with an external apparatus, an image sensor unit which photographs an image being displayed on the display apparatus at a photographing speed above a frame rate of the display apparatus, and a control unit which controls to identify pattern information based on a placement of a pattern frame included in the image photographed by the image sensor unit, and to receive data related to the display apparatus from the external apparatus based on the identified pattern information.
