AV Output Analysis Device HDMI Port Responsiveness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for analyzing audio/video (AV) output from sink devices, such as display products, face issues with interface compatibility between sink and source devices, leading to video output noise and audio output insensitivity, which are typically analyzed manually or through visual inspection.
Innovation Solution
An apparatus and method that utilize screen mirroring technology in a wireless connection environment between a sink device and a user terminal, combined with an image comparison algorithm, to automatically analyze AV output by comparing received data with reference data to determine HDMI signal responsiveness and detect noise or abnormalities in HDMI ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation and visual inspection are used to analyze AV output, then analysis can be performed, but the process is time-consuming and labor-intensive
Solution Approach 1:
The system enables automatic self-analysis of AV output by having the sink device capture its own screen output and transmit it to the analysis device, which automatically compares the captured data with reference data to detect compatibility issues without requiring manual visual inspection
Solution Approach 2:
The patent replaces manual visual inspection with automated data processing by capturing screen output as digital data, transmitting it wirelessly, and using computer algorithms to automatically compare and analyze the data, substituting the mechanical manual process with an automated information processing system
2Measurement precision
If camera-based noise capture is used to analyze AV output, then visual inspection is possible, but external noise and environmental factors affect analysis accuracy
Solution Approach 1:
The system uses screen mirroring technology as an intermediary to capture AV output data directly from the sink device's internal display output, rather than using an external camera that is susceptible to environmental noise. This intermediary approach ensures that the captured data represents the actual output signal without contamination from external factors
Solution Approach 2:
The patent creates a digital copy of the AV output through screen mirroring, where the sink device's display output is captured and transmitted as digital data to the analysis device. This digital copying process eliminates the need for optical capture and ensures accurate reproduction of the output signal without environmental interference
3Productivity
If automatic analysis using screen mirroring and image comparison is implemented, then analysis efficiency improves, but device complexity increases
Solution Approach 1:
The analysis device leverages existing screen mirroring functionality that is already present in many display systems, allowing the same infrastructure to serve both normal display operations and automated analysis purposes. This multi-functionality approach reduces the need for separate dedicated hardware while still achieving automatic analysis capabilities

AI summary
Provided is an apparatus, method, and computer-readable recording medium for analyzing audio/video (AV) output, capable of automatically analyzing an AV output of a sink device. The apparatus for analyzing an AV output includes: a transmitter configured to transmit a high-definition multimedia interface (HDMI) signal generation command to a source device such that an AV screen is output on a sink device; a receiver configured to receive, from a user terminal, data of a mirroring screen corresponding to the AV screen being output on the sink device, and a controller configured to perform analysis by comparing the received data of the mirroring screen with reference data stored in a memory to analyze a responsiveness for a HDMI signal of a HDMI port provided in the sink device.
