Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing telepresence systems face issues with smooth multiplexing transmission due to the use of traditional session systems based on conventional protocol architectures, leading to excessive port usage and inefficiencies.
Innovation Solution
The method involves telepresence endpoints exchanging multiplexing information, including indication, type, and mapping information, to enable efficient multiplexing transmission by carrying this information in signaling processes and extended headers during media stream transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional transmission mode transmitting one path of media stream via one port is adopted, then transmission simplicity is maintained, but number of ports increases excessively leading to NAT and firewall obstacles
Solution Approach 1:
The patent merges multiple media stream paths into a single transmission port by implementing multiplexing transmission. The telepresence endpoint combines multiple capture code streams (e.g., from different cameras or microphones) and transmits them through one shared port using multiplexing protocols, thereby reducing the total number of ports required while maintaining the ability to distinguish and process individual streams through multiplexing identifiers.
2Quantity of substance
If multiplexing transmission is performed on multiple paths of media streams on the same transmission address, then port usage is reduced, but compatibility between new devices and old devices becomes difficult to support
Solution Approach 1:
The patent implements a dual-mode transmission architecture that provides universal compatibility. The telepresence endpoint can operate in traditional one-to-one transmission mode for legacy devices that do not support multiplexing, while simultaneously supporting multiplexing transmission mode for modern devices. The system automatically detects device capabilities and adapts the transmission mode accordingly, ensuring broad compatibility across different device generations.
Solution Approach 2:
The patent employs dynamic mode switching capability where the transmission protocol can adaptively change between traditional and multiplexing modes based on real-time device compatibility requirements. This dynamic adjustment allows the system to optimize port usage when multiplying devices are present while falling back to simpler transmission modes when legacy devices are detected, thus maintaining versatility across diverse device ecosystems.
3Device complexity
If telepresence system uses conventional protocol architecture, then system simplicity is maintained, but multiplexing transmission is unsmooth
Solution Approach 1:
The patent segments the protocol architecture into distinct functional layers: a signaling layer for exchanging multiplexing information (including multiplexing indication information, multiplexing type information, and multiplexing mapping information), and a media transmission layer for actual stream transport. This segmentation allows the system to maintain the simplicity of conventional protocol structures while adding multiplexing capabilities through dedicated signaling messages that coordinate the multiplexing process without disrupting the underlying simple architecture.

AI summary
Provide are a method and device for exchanging endpoint information and a telepresence endpoint. The method includes that: multiplexing information is exchanged between telepresence endpoints. By means of the present disclosure, the problem in the related art that there are too many ports and multiplexing transmission is unsmooth due to the fact that a multiplexing transmission mode of a traditional session system is still adopted in a telepresence system based on a conventional protocol architecture is solved, and the effect of exchanging the multiplexing information between the telepresence endpoints and therefore multiplexing can be successfully performed in the telepresence system is further achieved.
