Dynamic Advertisement Playout Control for Live Video Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In live video streaming, advertisement placement must balance relevance and timing to avoid disrupting the user experience, as missing critical content can negatively impact quality of experience (QoE), and existing methods lack the ability to dynamically adjust advertisement playback based on the importance of the video content.
Innovation Solution
A method that receives advertisement content and live video streams, calculates a content importance rating using image and audio features, and postpones advertisement playback if the rating exceeds a threshold, ensuring critical content is not interrupted, while preserving advertisement effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If advertisement content is played out at predefined locations during live video streaming, then advertisement effectiveness is improved, but user experience deteriorates when critical video content is interrupted
Solution Approach 1:
The system dynamically adjusts advertisement playout timing based on real-time analysis of video content importance. The video player continuously evaluates upcoming video segments and adapts advertisement delivery timing accordingly, transitioning from static predefined placement to dynamic context-aware placement that prevents interruption of critical content while maintaining advertisement delivery
Solution Approach 2:
The system implements feedback mechanisms where the video player analyzes video content features (such as scene changes, audio levels, content type) and uses this information to make real-time decisions about advertisement playout. This closed-loop feedback ensures advertisements are delivered effectively without degrading user experience by interrupting important content
2Reliability
If advertisement playout timing is strictly followed according to markers, then advertisement relevance is improved, but video content completeness deteriorates
Solution Approach 1:
The video player performs preliminary analysis of upcoming video content segments before reaching advertisement markers. By evaluating the importance of upcoming video content in advance, the system can proactively adjust advertisement playout timing to avoid interrupting critical content while still meeting advertisement delivery requirements
Solution Approach 2:
The system changes the timing parameter of advertisement playout based on evaluated video content importance. When important content is detected, the advertisement playout time is shifted or postponed, dynamically adjusting the timing parameter to balance advertisement delivery with content preservation

AI summary
A method (100) of controlling playout of advertisement content during live video streaming at an end-user terminal comprising steps of: receiving (110) advertisement content from an advertisement server; receiving (112) live streamed video content from a content delivery network and playing out the video content; obtaining (114) at least one of image features and audio features of the video content during playout; calculating (116) a content importance rating of video content to be played out during a prediction time window based on said features; and postponing (118) playout of advertisement content scheduled to be played out during the prediction time window if the calculated content importance rating for the prediction time window is above a threshold value.
