Avatar Model Manifest Transmission for Low-Latency 5G Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of reducing initial delay time in transmitting large avatar models over 5G networks, which can significantly degrade Quality of Service (QoS) compared to video calls, is addressed by dividing the avatar model into multiple data types and configuring a manifest to facilitate step-by-step transmission based on network availability and user interaction.
Innovation Solution
The avatar model is divided into types such as mesh, texture, and skeleton, with a manifest detailing alternative and supplementary relationships between these data types, allowing selective reception and display at varying resolutions and densities, and using transmission hints to generate SDP offers for each step, enabling efficient data transmission over 5G networks.

Engineering Contradiction Analysis
1Measurement precision
If the avatar model is transmitted as a complete large-sized file, then the avatar representation is complete and high-quality, but the initial delay time increases significantly
Solution Approach 1:
The avatar model is divided into multiple independent data types including mesh data, texture data, skeleton data, and animation data. Each data type is transmitted separately through different channels, allowing the receiver to progressively reconstruct the avatar model as data arrives, thereby reducing initial delay while maintaining complete representation
Solution Approach 2:
The manifest file is prepared in advance containing metadata about all avatar model components, their relationships, and transmission priorities. This preliminary structure enables the receiving terminal to efficiently process and assemble avatar data as it arrives, reducing assembly time and initial delay without compromising representation quality
2Measurement precision
If high-resolution avatar data is transmitted, then the avatar representation quality is high, but the data transmission time and network bandwidth consumption increase
Solution Approach 1:
The system dynamically adjusts the transmission and rendering of avatar data based on network conditions and user needs. The manifest file contains alternative data specifications allowing the receiver to select appropriate resolution levels for different avatar components, enabling high quality representation when bandwidth is available while reducing transmission time when bandwidth is limited
Solution Approach 2:
Different parts of the avatar model are transmitted and rendered with different quality levels based on their importance and visual impact. Critical components like mesh structure receive higher priority and higher resolution, while less critical components use lower resolution, optimizing the balance between representation quality and transmission time
