Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate channels are established for AR auxiliary data and media streams, then data transmission reliability is improved, but system complexity and latency increase
Solution Approach 1:
The patent merges the AR auxiliary data channel and media stream channel into a single unified transmission channel. This allows both AR auxiliary data and media streams to be transmitted together through the same channel, reducing channel management complexity while maintaining transmission reliability through unified error handling and acknowledgment mechanisms.
Solution Approach 2:
The unified channel is designed to handle multiple types of data simultaneously - both AR auxiliary data and media streams can be transmitted through the same channel. This multi-functional channel design reduces the number of separate channels needed while maintaining the reliability requirements for different data types through priority-based transmission and unified error handling.
2Loss of information
If separate channels are established for AR auxiliary data and media streams, then data organization is improved, but transmission latency increases
Solution Approach 1:
By combining AR auxiliary data and media streams into a single channel, the patent eliminates the time delay associated with switching between separate channels. Both data types are transmitted simultaneously in the same channel, reducing transmission latency while maintaining data organization through protocol-level separation and priority handling.
Solution Approach 2:
The unified channel enables continuous transmission without the interruptions that would occur when switching between separate channels. The channel remains actively transmitting data throughout the communication session, eliminating idle time and reducing overall latency while maintaining proper data organization through continuous protocol processing.
3Reliability
If multiple independent channels are used for AR communication, then communication reliability is improved, but user experience deteriorates due to increased latency
Solution Approach 1:
The patent combines multiple independent channels into a unified channel that handles both AR auxiliary data and media streams. This merging maintains communication reliability through unified error handling and acknowledgment mechanisms while reducing the latency that would otherwise degrade user experience in augmented reality applications.
Solution Approach 2:
The patent changes the transmission parameters by using a single channel with priority-based data handling instead of multiple independent channels. This parameter change reduces transmission latency and improves user experience while maintaining communication reliability through protocol-level error handling and acknowledgment mechanisms.
Data Source
AI summary
An augmented reality communication method in which AR is integrated into voice and video calls is disclosed. An auxiliary data channel and a media stream channel are established between a terminal device and an AR media processing network element. In addition, AR auxiliary data and a media stream have a same transmission path. The AR media processing network element may be an IMS access gateway having an AR processing capability or a media resource function MRF.
