Display Image Quality Sync Across Multi-Device Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-device experience (MDE) services face challenges in providing a consistent image quality experience across multiple devices due to differences in display features, leading to inconsistent viewing experiences when content is shared.
Innovation Solution
An electronic apparatus and method that dynamically adjusts its image quality settings based on obtained image quality information from a predetermined device or the device on which content is most recently played back, using a communication interface to share this information among devices, and adjusting settings based on resolution, panel type, and panel performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image quality information is shared among multiple devices, then consistent image quality experience is achieved, but device complexity increases due to communication interfaces and coordination mechanisms
Solution Approach 1:
The patent introduces an external server as an intermediary to manage image quality information sharing among multiple devices. The server receives, stores, and distributes image quality information (including color temperature, gamma, brightness, color, sharpness, motion processing, and contrast ratio) to participating devices, eliminating the need for direct peer-to-peer communication and reducing system complexity while ensuring consistent image quality experience across devices
Solution Approach 2:
The external server provides universal image quality management services that can be accessed by multiple different types of devices (TVs, smartphones, tablets, etc.). The server handles various image quality parameters and works with different display specifications (resolution, panel type, panel performance) through a unified interface, enabling multi-device experience (MDE) services across diverse device ecosystems
2Reliability
If image quality settings are dynamically adjusted based on external device information, then image quality consistency is improved, but processing time and complexity increase
Solution Approach 1:
The system performs preliminary actions by having devices obtain and share their image quality information (color temperature, gamma, brightness, color, sharpness, motion processing, contrast ratio) with the external server in advance. The server stores this information and makes it available for quick retrieval when content is shared across devices, eliminating the need for real-time analysis and reducing processing delays during actual content playback
Solution Approach 2:
The patent implements a feedback mechanism where the electronic device continuously monitors its own image quality settings and sends updated information to the external server. The server uses this feedback to maintain an up-to-date profile of each device's characteristics, enabling rapid and accurate image quality adjustments when content is shared without requiring extensive real-time processing
3Adaptability or versatility
If image quality information is obtained from predetermined devices or most recently played back devices, then adaptability is improved, but information accuracy may deteriorate due to device selection criteria
Solution Approach 1:
The patent adjusts image quality parameters (color temperature, gamma, brightness, color, sharpness, motion processing, contrast ratio) based on the specific display characteristics of different devices including resolution, panel type, and panel performance. The external server selects and applies appropriate parameters from the shared information pool according to each device's specifications, ensuring accurate and adaptive image quality optimization for diverse display technologies

AI summary
An electronic apparatus may include: a display; a memory for storing at least one instruction; and one or more processors connected to the display and the memory to control the electronic apparatus, wherein the one or more processors may individually and/or collectively execute the at least one instruction to, when content is played back according to a pre-set event, obtain at least one of image quality information of a predetermined device among at least one external device or image quality information of a device in which the content is most recently played back based on a playback time point of the content, and change an image quality setting of the display on the basis of the obtained image quality information.
