Quick Connect Code for Wireless Display Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face challenges in seamlessly synchronizing visual outputs between multiple devices, particularly in presentation settings where authorized sources are required, and there is a need for improved methods to facilitate access and communication of visual information across devices.
Innovation Solution
A display system comprising receiver and transmitter circuitry that utilizes a quick connect (QC) code value to enable wireless communication and synchronization of visual outputs, where the QC code value is generated from the receiver's network address and used to transmit signals between devices, allowing for synchronous display of visual content across connected displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a full network address is used for device identification, then the address provides complete and unique identification, but the address becomes difficult to read and input manually
Solution Approach 1:
The patent creates a simplified copy (QC code) of the full network address that can be easily read and input. The QC code serves as a human-readable representation that maps to the complete technical address, allowing users to interact with the system using the simplified form while the system handles the full address internally.
2Measurement precision
If devices communicate using full network addresses, then precise device identification is achieved, but communication efficiency decreases due to address resolution overhead
Solution Approach 1:
The system performs preliminary action by pre-resolving network addresses to QC codes and storing these mappings. When communication is needed, the system can quickly lookup the pre-resolved QC code instead of performing full address resolution at the moment of communication, thereby improving efficiency while maintaining precision.
3Reliability
If multicast DNS traffic is blocked at the receiver, then network security and control are improved, but device discovery and connection establishment become more difficult
Solution Approach 1:
The QC code acts as an intermediary that bridges the gap between blocked multicast DNS traffic and the need for device discovery. Instead of relying on blocked multicast protocols, the system uses the QC code as an alternative identification mechanism that works within the constrained network environment, maintaining both security and ease of connection.
Data Source
AI summary
Access to a device that is associated with a display such as a visual projection device, is permitted based on data included in data bearing records. The device operates as a receiver and has an address associated with receiver circuitry in the device. The device operates to generate at least one data bearing record including a quick connect code value that corresponds to the receiver device address. The quick connect code value in the data bearing record is used by a transmitter device to send wireless signals to the receiver device to produce visual outputs from the display associated with the receiver that correspond to current visual outputs from a display associated with the transmitter.
