Hash-Based Signal Reception Verification in Virtual Meetings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During online meetings and video conferences, there is a lack of real-time assurance that audio and video signals are being received by all participants, leading to interruptions and inefficiencies due to hardware, software, or network issues.
Innovation Solution
A method is implemented where a server generates a hash from a data stream shared by a host computing device and compares it to a hash generated by user computing devices, determining the status of the online connection and displaying indications of successful or failed signal receipt, allowing for immediate issue resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional online meeting systems are used without signal reception verification, then the system remains simple and requires minimal additional components, but participants cannot determine whether audio and video signals are being received, leading to meeting interruptions and inefficiencies
Solution Approach 1:
The patent implements a feedback mechanism where receiving devices generate hash values from received data streams and transmit them back to the host device. The host device compares these received hash values with independently generated hash values to determine whether signals are being successfully received. This feedback loop provides real-time verification of signal reception without significantly complicating the overall system architecture.
Solution Approach 2:
The patent introduces hash values as an intermediary element that mediates between the data stream transmission and the verification process. Instead of directly comparing complex data streams, the system uses hash values (generated through cryptographic hashing) as simplified intermediaries that represent the received data. This intermediary approach enables efficient verification while maintaining system reliability.
2Productivity
If real-time signal reception verification is implemented using hash comparison, then uninterrupted meetings can be ensured, but additional processing steps and communication overhead are introduced
Solution Approach 1:
The patent performs hash generation at multiple points in advance: the host device generates hash values from the data stream before transmission, and receiving devices generate hash values from received data before comparison. This preliminary action ensures that when verification is needed, the comparison can occur rapidly without delaying the meeting flow, as all necessary hash values are already prepared.
Solution Approach 2:
The patent transforms the complex verification problem into a simpler parameter comparison task. Instead of analyzing entire data streams for reception verification, the system converts data streams into hash values (changing the parameter representation) and compares only these condensed parameters. This parameter transformation dramatically reduces processing time while maintaining verification accuracy.
3Measurement precision
If hash values are generated and compared for every data stream segment, then accurate reception status can be determined, but computational resources and energy consumption increase
Solution Approach 1:
The patent extracts only the essential verification information from the data stream by generating hash values. Instead of processing and analyzing the entire data stream for reception verification, the system extracts a condensed hash representation that captures the essential characteristics of the received data. This extraction approach maintains measurement precision while significantly reducing computational energy consumption.
Solution Approach 2:
The patent uses hash values as disposable, computationally inexpensive objects for verification purposes. Hash generation and comparison are relatively low-cost operations compared to full data stream analysis. These hash values serve their verification purpose and are then discarded, enabling accurate reception detection without sustained high energy consumption.
Data Source
AI summary
A method, a system, and a computer program product for determining whether signals are received by one or more devices in a virtual meeting. The method includes transmitting a data stream received from one or more host computing devices to one or more user computing devices in a plurality of user computing devices. The host and user computing devices are communicatively coupled using a real-time online connection. A first hash in a plurality of hashes is generated by the server using a portion of the data stream and stored in a memory location. The first hash is compared to a second hash received from the user computing devices. The second hash is generated by the user computing devices upon receipt of the transmitted data stream. Based on the comparison, a status of the real-time online connection between the host computing devices and the user computing devices is determined.
