Status-Driven Point Cloud Transmission for Immersive Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of point cloud data requires significant bandwidth and processing power, especially in immersive media applications like immersive point cloud games, due to the large amount of data and the need to transmit all data at once, which can overwhelm user devices.
Innovation Solution
A data transmission method that selects and transmits status-dependent point cloud spatial region information and data based on current user status, reducing the amount of data transmitted and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all point cloud data is transmitted to users, then complete immersive experience is provided, but bandwidth consumption increases and device processing requirements become too high
Solution Approach 1:
The patent divides the point cloud data into multiple spatial regions (first spatial region, second spatial region, etc.) based on user status. Only the regions relevant to the current user status are selected for transmission, rather than transmitting all data. This segmentation allows the system to maintain immersive experience quality for relevant regions while reducing overall data transmission volume.
Solution Approach 2:
The patent applies different transmission strategies to different spatial regions based on their relevance to user status. High-priority regions corresponding to current user status receive detailed point cloud data, while other regions may receive reduced or no data. This local quality approach ensures that critical areas maintain high fidelity while reducing total bandwidth consumption.
2Loss of information
If all point cloud data is transmitted, then data completeness is ensured, but data transmission efficiency decreases
Solution Approach 1:
The patent performs preliminary selection of point cloud spatial region data based on user status before transmission. The server determines which spatial regions are relevant to the current user status and pre-selects only those regions for transmission. This preliminary action ensures that the transmitted data is both complete for the relevant regions and efficient in terms of bandwidth usage.
Solution Approach 2:
The patent transmits only the necessary portion of point cloud data corresponding to the current user status rather than all available data. By transmitting partial data that is sufficient for the user's current needs, the system achieves good transmission efficiency while maintaining adequate data completeness for the immersive experience.
3Quantity of substance
If status-dependent point cloud spatial region data is selected and transmitted, then bandwidth usage is reduced, but system complexity increases
Solution Approach 1:
The patent uses user status information as feedback to guide the selection of point cloud spatial region data. The server receives user status feedback and dynamically determines which spatial regions should be transmitted. This feedback mechanism enables automated, status-dependent data selection that reduces bandwidth usage while keeping the processing logic relatively simple and rule-based.
