Video Engagement Estimation via Terminal Parameter Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques lack the ability to effectively estimate engagement (view duration, view acceptance, and stop/exit) in video communication services, particularly in adaptive bit rate video delivery, due to the inability to monitor engagement metrics directly from user terminals.
Innovation Solution
An engagement estimation apparatus and method that acquires parameters related to video coding quality and viewing state, using units like initial loading delay, stalling length, and video view duration to calculate an engagement index, allowing for real-time estimation of viewer engagement based on observable parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If quality parameters are measured from reception terminal packets, then video quality can be estimated, but engagement metrics cannot be obtained
Solution Approach 1:
The reception terminal performs multiple functions: it not only measures video quality parameters from packets but also collects engagement metrics (view duration, view acceptance, stop/exit) and transmits all data to the estimation server, enabling both quality and engagement assessment from a single terminal
Solution Approach 2:
The estimation server acts as an intermediary that receives both quality parameters and engagement metrics from the terminal, processes them together, and generates comprehensive evaluation results, bridging the gap between quality measurement and engagement tracking
2Productivity
If engagement estimation is implemented using terminal observable parameters, then real-time monitoring is enabled, but system complexity increases
Solution Approach 1:
The reception terminal automatically collects engagement metrics (view duration, view acceptance, stop/exit) and quality parameters without requiring additional manual intervention or complex external systems, performing the measurement function itself
Solution Approach 2:
The terminal pre-collects and transmits both quality parameters and engagement metrics to the estimation server before comprehensive analysis is performed, preparing data in advance to simplify the overall processing workflow

AI summary
An engagement estimation apparatus includes an acquisition unit configured to acquire, for each measurement section after an instruction of a start of a view of an video delivered through a network, any of a parameter related to a coding quality of the video in the measurement section and a parameter related to a viewing state of the video in the measurement section, and an estimation unit configured to calculate an estimation value of an index for evaluation of engagement for each measurement section based on a parameter acquired by the acquisition unit in the measurement section. Thus, it is possible to estimate engagement based on parameters that can be observed in a terminal.
