Immersive Media Resolution Selection for Bandwidth-Aware Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersive media transmission solutions fail to balance user experience and bandwidth resource utilization, as they either randomly select file tracks of specific resolutions or deliver all resolutions, leading to inefficiencies.
Innovation Solution
A method and apparatus that add resolution description and selection strategy information to immersive media content, allowing servers to determine and transmit a target resolution based on client capabilities, ensuring optimal resolution selection and improved bandwidth utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all file tracks of multiple resolutions are delivered to the client, then user experience is improved through higher quality content, but bandwidth resource utilization deteriorates due to excessive data transmission
Solution Approach 1:
The patent changes the parameter of resolution selection from static (random or all resolutions) to dynamic (adaptive based on client capabilities). The server determines the target resolution by evaluating client device parameters, network conditions, and content characteristics, thereby optimizing the balance between user experience and bandwidth consumption.
Solution Approach 2:
The resolution selection mechanism transitions from a static approach to a dynamic one. The system continuously adapts the delivered resolution based on real-time client capabilities and network conditions, allowing the same content to be delivered at different resolutions to different clients or to the same client under different conditions.
2Loss of energy
If a specific resolution file track is randomly selected, then bandwidth resource utilization is improved through reduced data transmission, but user experience deteriorates due to mismatched resolution quality
Solution Approach 1:
The system implements a feedback mechanism where the server receives information about client capabilities (device type, screen resolution, network bandwidth) and uses this feedback to determine the appropriate target resolution. This closed-loop approach ensures that the selected resolution matches both the client's ability to display it and the user's quality expectations.
Solution Approach 2:
The selection criterion changes from random choice to parameter-based selection. The server evaluates multiple parameters including client device capabilities, network conditions, and content characteristics to determine the optimal resolution, transforming the decision process from stochastic to deterministic based on measured parameters.

AI summary
A method for providing immersive media, performed by at least one processor includes adding resolution description information and resolution selection strategy information to file format information of immersive media content, determining a target resolution to be provided to a client based on the resolution description information and the resolution selection strategy information of the immersive media content, and transmitting an immersive media file of the target resolution to the client.
