Video-Download Quality Rating Through Objective Event Metrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for rating video-download quality rely on subjective scores that are unreliable and vary based on user expectations, making them inaccurate and difficult to implement effectively.
Innovation Solution
An apparatus and method that objectively rate video-download quality by monitoring quantitative properties such as download duration, buffer-underflow events, and start delay, allowing for adaptive and automated rating systems that account for time and location variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If subjective scoring methods are used to rate video-download quality, then user expectations can be considered, but the ratings become unreliable and vary significantly
Solution Approach 1:
The patent replaces the mechanical system of subjective human scoring with an automated computational system that objectively measures download performance metrics (download duration, buffer underruns, completion rate) to generate consistent quality ratings across all users, eliminating human variability while maintaining adaptability through configurable threshold parameters
Solution Approach 2:
The system enables self-service rating generation by automatically collecting download event data, processing performance metrics, and generating quality ratings without requiring human operators to manually assess each download, thereby ensuring both reliability through consistency and adaptability through automated parameter adjustment
2Measurement precision
If detailed monitoring of multiple download parameters is implemented, then measurement accuracy improves, but system complexity increases
Solution Approach 1:
The patent extracts only the most critical download performance parameters (download duration, buffer underrun events, download completion status) from the complex stream of download event data, focusing measurement efforts on these key indicators to maintain high measurement precision while avoiding the complexity of monitoring all possible download metrics
Solution Approach 2:
The monitoring system is designed to universally collect multiple download parameters through a single integrated data collection mechanism that can track various metrics (bytes downloaded, time stamps, buffer events) simultaneously, reducing overall system complexity by consolidating multiple monitoring functions into one unified system
3Reliability
If automated rating systems are deployed across multiple networks and geographic areas, then data coverage and reliability improve, but the ability to account for local variations decreases
Solution Approach 1:
The patent applies local quality by configuring different threshold parameters and rating criteria for different networks and geographic areas, allowing the automated system to adapt to local network conditions, user expectations, and environmental factors while maintaining the reliability benefits of automated processing across all locations
Solution Approach 2:
The system implements dynamics by allowing threshold parameters and rating criteria to be dynamically adjusted for different networks and geographic regions, enabling the automated rating system to respond to local variations in network performance, user behavior, and environmental conditions while maintaining consistent automated processing reliability
Data Source
AI summary
Apparatus for rating download events is described. The apparatus includes a network interface and a processor. The processor, via the interface, monitors one or more download events in which content is downloaded by one or more users. In response to the monitoring, the processor identifies at least one quantitative property of the download events. Based on the property, the processor assigns a rating to the download events that is indicative of an estimated user-perceived quality of the download events. The processor then generates an output indicative of the rating. Other embodiments are also described.
