Virtual Media Client for Linear Channel QoE Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to accurately evaluate the quality of experience for linear media channels on mobile platforms due to variability in user media clients' hardware and software, privacy restrictions, and inconsistent performance data collection, which can lead to inaccurate assessments of communication services.
Innovation Solution
Implementing a virtual media client onboard the mobile platform to emulate various user devices, collect performance data, and transmit it to a scoring subsystem for unified quality of experience evaluation, alongside an on-ground server for comprehensive analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If performance data is collected from multiple user media clients with different hardware and software configurations, then the evaluation should reflect real-world variability, but the measurement accuracy deteriorates due to inconsistent data quality across devices
Solution Approach 1:
The patent introduces a virtual media client as an intermediary device that standardizes performance data collection. This virtual client acts as a mediator between the diverse physical user devices and the evaluation system, normalizing data from different hardware/software configurations into a consistent format that can be accurately measured and compared.
Solution Approach 2:
The system creates a virtual copy of a media client that emulates the behavior and data collection capabilities of actual user devices. This virtual replica allows the system to gather standardized performance metrics without being directly affected by the variability of physical devices, thus maintaining measurement precision while still reflecting real-world conditions.
2Reliability
If performance data is collected from actual user media clients, then real usage patterns are captured, but privacy restrictions prevent access to necessary performance information
Solution Approach 1:
Instead of directly accessing sensitive data from user devices, the system uses a virtual media client that replicates the data collection process. This copy allows the system to obtain authentic performance information about media channel quality without needing to access or store actual user data, thus maintaining reliability while overcoming privacy restrictions.
Solution Approach 2:
The virtual media client serves as an intermediary that collects performance data in a privacy-preserving manner. It obtains the necessary performance information about linear media channels without requiring direct access to user personal data or device internals, thus maintaining data authenticity while respecting privacy constraints.
3Measurement precision
If a virtual media client is implemented to standardize data collection, then measurement accuracy improves, but system complexity increases due to additional onboard components
Solution Approach 1:
The patent implements a virtual media client as a software-based copy rather than requiring additional physical hardware. This virtualization approach provides standardized measurement capabilities while minimizing the increase in physical device complexity, as the virtual client can run on existing onboard computing resources.

AI summary
A communication system comprises an onboard server situated onboard a mobile platform and a remote server situated outside the mobile platform. The remote server is configured to generate one or more linear media channels for use by the onboard server. The communication system further comprises a virtual media client situated onboard the mobile platform. The virtual media client is configured to receive linear media channels from the onboard server and transmit performance data to the onboard server. The onboard server is configured to receive one or more media requests from a plurality of user media clients onboard the mobile platform. The one or more media requests specify one or more linear media channels. The onboard server is further configured to receive the one or more linear media channels from the remote server, provide the one or more linear media channels to the plurality of user media clients according to the received one or more media requests, provide at least a first linear media channel of the one or more media channels to the virtual media client; and receive a first set of performance data associated with the first linear media channel from the virtual media client.
