P2P Video and Haptic Data Transmission via Server Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transmitting video and haptic data over wireless local area networks, 3G telecommunication networks, and dedicated communication channels are limited by short communication distances, high costs, and restrictive user positions, failing to enable efficient long-distance, low-cost, and scalable avatar networks for remote control applications.
Innovation Solution
A method utilizing Peer-to-Peer technology over the Internet to establish direct communication channels for video and haptic data transmission between mobile video acquisition devices and remote computers, allowing for the registration of address information on a server to create dedicated channels for video and haptic data, enabling rich haptic control and low-cost, long-distance avatar networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If WLAN is used to transmit video data and haptic data, then high bandwidth and smooth transmission are achieved, but communication distance is limited to short range
Solution Approach 1:
The patent introduces a server as an intermediary component that facilitates connection between the video acquisition device and remote client devices through the Internet. The server receives registration information from the video acquisition device, processes connection requests, and enables long-distance communication without requiring direct peer-to-peer connection, thus resolving the contradiction between maintaining high transmission quality and extending communication distance
2Length of moving object
If 3G telecommunication network is used for long-distance transmission, then communication distance is extended, but data transmission cost increases significantly
Solution Approach 1:
The patent utilizes the Internet as a universal communication infrastructure that can serve multiple purposes and users simultaneously. By leveraging the existing Internet infrastructure instead of dedicated 3G networks, the system achieves long-distance communication capability while significantly reducing transmission costs, as the Internet provides a cost-effective platform for global data exchange
3Length of moving object
If dedicated communication channel is established for video and haptic data transmission, then long-distance communication is achieved, but system complexity and signaling requirements increase
Solution Approach 1:
The patent extracts the complex signaling and connection management functions from the communication channels and consolidates them into the server. The server handles all registration, authentication, and connection establishment processes, while the video acquisition device and client devices only need to perform simple registration and data transmission, thus reducing the signaling complexity at the device level
4Length of moving object
If P2P technology is used over Internet, then long-distance low-cost communication is achieved, but direct connection establishment becomes difficult without public IP addresses
Solution Approach 1:
The patent introduces a server as an intermediary that simplifies the connection establishment process for P2P communication. The server acts as a rendezvous point where devices can register their presence and exchange connection information without requiring complex NAT traversal or hole-punching techniques, making P2P communication over Internet accessible to devices with private IP addresses

AI summary
A method for transmitting video data and haptic data between a mobile video acquisition device and a remote computer through a communication network, and a video acquisition device. A server capable of direct communication exists in the communication network. The video data can be presented on a screen of the remote computer for a user to view, and the haptic data can be used to control a motion state of the video acquisition device acting as an avatar of the user. In the present invention, a first channel for transmitting video data and a second channel for transmitting haptic data are established between a computer having access to the Internet and a video acquisition device having access to the Internet by using a server and through a P2P technology. The present invention enables forming of a low-cost long-distance avatar network of multiple users versus multiple avatars, thereby greatly reducing travel of people, and contributing to low carbon environmental protection.
