Image Signal Encoding for Display Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face delays in displaying image signals due to the need for frame rate and resolution conversion processing, which increases the time required to display images on a display panel after receiving the signal from a source device.
Innovation Solution
An image providing apparatus that acquires specification information of a display apparatus and encodes image signals according to the display's frame rate and resolution, allowing for direct transmission without the need for conversion processing, thereby reducing display delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the source device encodes the image signal independently regardless of the display apparatus performance, then the image quality is optimized, but the display time is delayed due to frame rate and resolution conversion processing at the display apparatus
Solution Approach 1:
The source device performs frame rate and resolution conversion in advance during the encoding process, matching the display apparatus specifications before transmission. This preliminary adaptation eliminates the need for conversion processing at the display apparatus, thereby reducing display time while maintaining optimized image quality.
Solution Approach 2:
The source device dynamically adjusts encoding parameters (frame rate, resolution) based on the display apparatus specifications acquired through communication. By changing these parameters during the encoding stage rather than at the display stage, the system achieves both image quality optimization and reduced display delay.
2Adaptability or versatility
If the source device performs frame rate conversion to match the display apparatus panel frame rate, then the display compatibility is improved, but the processing time increases
Solution Approach 1:
Frame rate conversion is performed in advance during the encoding process at the source device, rather than in real-time at the display apparatus. This preliminary conversion ensures display compatibility while minimizing processing time impact on the final display performance.
Solution Approach 2:
The patent replaces the mechanical conversion processing system at the display apparatus with a software-based encoding system at the source device. This substitution allows frame rate conversion to be integrated into the encoding workflow, reducing the need for separate conversion hardware and processing steps at the display end.
3Manufacturing precision
If the display apparatus performs resolution conversion processing, then the image signal adapts to the display panel, but the display delay increases
Solution Approach 1:
Resolution conversion is performed in advance during the encoding process at the source device, matching the display apparatus resolution specifications before transmission. This preliminary adaptation ensures the image signal is already optimized for the display panel, eliminating the need for resolution conversion at the display apparatus and thereby reducing display delay.

AI summary
An image providing apparatus includes: a communication interface configured to perform communication with a display apparatus in a predetermined communication interface method; and a processor configured to acquire specification information of the display apparatus, to encode a first image signal to correspond to the predetermined communication interface method by applying at least one of a frame rate and a resolution corresponding to the acquired specification information, and to control the communication interface to transmit the encoded first image signal to the display apparatus.
