Middleware Consolidating DASH QoE and MBMS Reports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for delivering digital video data face challenges in consolidating Quality of Experience (QoE) metrics reporting, as they typically require separate reporting points for multimedia broadcast/multicast services (MBMS) and video clients, leading to fragmented performance monitoring for service providers.
Innovation Solution
A middleware unit is introduced to act as a proxy, caching media data and instructing DASH clients to report QoE metrics to it instead of or in addition to the conventional DASH QoE metrics server, allowing these reports to be aggregated with MBMS reception reports and sent to a reception reporting server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate reporting points are used for MBMS and video clients, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines MBMS reception reports and DASH QoE metrics reports into a single unified reporting mechanism. The network device receives both types of reports through the same interface and processing path, consolidating what would otherwise require separate reporting points. This merging maintains comprehensive measurement capability while reducing system complexity by eliminating redundant reporting infrastructure.
Solution Approach 2:
The network device is designed to handle multiple types of reports (MBMS reception reports and DASH QoE metrics) through a single universal reporting interface. This multi-functional approach allows the same reporting mechanism to serve multiple measurement purposes, thereby improving measurement precision across different service types without requiring separate specialized reporting systems for each.
2Measurement precision
If multiple reporting points are implemented, then measurement precision is improved, but loss of time increases
Solution Approach 1:
By merging MBMS and DASH reporting into a single unified process, the patent eliminates the time required for separate report collection, transmission, and processing at multiple reporting points. The consolidated approach allows both types of metrics to be received and processed simultaneously through one interface, reducing the total time loss while maintaining comprehensive measurement precision.
3Reliability
If separate reporting mechanisms are used for MBMS and video clients, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple reporting mechanisms into a single unified reporting system that handles both MBMS reception reports and DASH QoE metrics. This consolidation maintains reliability by ensuring comprehensive coverage of all service types while reducing infrastructure complexity by eliminating redundant reporting paths, interfaces, and processing systems that would otherwise be required.

AI summary
An example device for generating quality measurement reports includes one or more hardware-based processors implemented using digital circuitry, the processors being configured to execute a middleware unit and a target application for media data. The middleware unit is configured to receive media data via broadcast or multicast from a server device, generate reception reports covering the reception of the media data according to received reporting directives, deliver at least part of the media data to a target application of the client device, receive quality of experience (QoE) reports from the target application, and provide contents of the QoE reports to a reception reporting server.
