Video Quality Scoring via Content Delivery Subsystems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network technologies lack effective solutions for assessing the quality of video content delivered over wireless networks, which hinders network operators' ability to ensure high-quality user experiences and charge premiums accordingly.
Innovation Solution
A system where content delivery subsystems communicate video quality data to a network device, which generates video quality metrics and scores, and creates reports that include these metrics, enabling network operators to assess user viewing experiences and network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video content is delivered over wireless networks using current network technologies, then video content can be transmitted to user devices, but the quality of video content delivery cannot be adequately assessed
Solution Approach 1:
The patent introduces content delivery subsystems (CDSs) as intermediary components that collect video quality data from multiple sources (network conditions, device characteristics, content properties) and relay this information to a network device for scoring. These CDSs act as mediators between the video delivery infrastructure and the quality assessment mechanism, enabling comprehensive quality measurement without disrupting the existing video delivery workflow.
Solution Approach 2:
The system implements a feedback mechanism where video quality scores are generated based on collected quality data and fed back to network operators. This feedback loop enables continuous monitoring and assessment of video delivery quality, allowing operators to identify quality issues and make informed decisions about network optimization and service improvement.
2Reliability
If network operators want to ensure high-quality user experiences and charge premiums, then they need video quality assessment capabilities, but current technologies do not provide such solutions
Solution Approach 1:
The patent segments the video quality assessment system into distinct functional components: content delivery subsystems (CDSs) that collect quality data from various sources, a network device that processes the data and generates quality scores, and reporting mechanisms that deliver results to network operators. This segmentation allows each component to perform its specific function efficiently, reducing overall system complexity while maintaining comprehensive quality assessment capabilities.
Solution Approach 2:
The content delivery subsystems are designed to perform multiple functions: collecting network condition data, device characteristics, content properties, and video delivery metrics all through a unified data collection mechanism. This multi-functionality reduces the need for separate specialized systems, thereby reducing overall device complexity while providing comprehensive quality assessment.

AI summary
A network device may be configured to receive video quality data that includes information corresponding to a delivery of video content from a content source to a user device via a network and information corresponding to video presentation conditions corresponding to the user device. The network device may also be configured to determine video quality metrics based on the video quality data. Each of the video quality metrics may correspond to a characteristic of the delivery of the video content from the content source to the user device or the video presentation conditions corresponding to the user device. The network device may also be configured to determine, based on the video quality metrics, a video quality score that corresponds to an estimated user viewing experience corresponding to the video content. The network device may also be configured to communicate the video quality score to an operator of the network.
