Ad Replacement System for Personalized Video Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional linear television advertising is not effectively targeted to individual viewers, as it is typically delivered to a common audience, limiting the ability to provide personalized advertising in packet-switched networks.
Innovation Solution
A method and system that detect existing advertisements in a video stream, identify users watching linear channels over a packet-switched network, and replace them with targeted advertisements based on unique user identifiers, allowing for personalized advertising by selecting and transmitting replacement advertisements from an advertisement server, while tracking viewer interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional linear television advertising is delivered to a common audience, then the system complexity is low and ease of operation is high, but the advertising targeting precision is poor and viewer engagement is limited
Solution Approach 1:
The patent segments the common audience into individual user groups, allowing each user to receive personalized advertisements. The system divides the broadcast stream into multiple targeted streams based on user profiles, enabling precise advertising delivery to specific demographic or behavioral segments while maintaining the linear TV broadcast model.
Solution Approach 2:
The patent introduces an intermediary system (ad insertion device or smart gateway) that sits between the broadcast signal and the user's display device. This intermediary intercepts the linear TV signal, identifies the user, and inserts personalized advertisements without requiring changes to the broadcast infrastructure itself, thus resolving the complexity issue.
2Productivity
If replacement advertisements are selected and transmitted to each user based on unique identifiers, then personalized advertising is achieved and viewer engagement is enhanced, but the transmission time and network bandwidth requirements increase
Solution Approach 1:
The patent performs preliminary actions by pre-segmenting the advertisement content and preparing user-specific ad streams before the actual broadcast. User profiles and advertising preferences are established in advance, allowing the system to quickly swap between pre-prepared advertisement segments during transmission without real-time processing delays.
Solution Approach 2:
The patent creates copied versions of the linear TV stream with different advertisement insertions for different user groups. Instead of transmitting entirely different content, the system copies the base program stream and inserts targeted advertisements into specific time codes, reducing the overall transmission time compared to creating entirely separate personalized streams.
3Adaptability or versatility
If traditional advertisements are used for linear television channels delivered over packet-switched networks, then compatibility with existing broadcast infrastructure is maintained, but the ability to provide targeted advertising is lost
Solution Approach 1:
The patent makes the broadcast system universal by enabling it to serve both traditional linear TV delivery and personalized advertising functions through a single infrastructure. The system can operate in traditional mode for users who don't require personalization while simultaneously providing targeted advertising to users who do, making the infrastructure adaptable to multiple use cases.
Solution Approach 2:
The patent implements self-service by allowing user devices to automatically identify themselves and receive appropriate advertisement streams without manual configuration. The system autonomously matches users with their personalized ad content based on pre-stored profiles, eliminating the need for complex manual setup or intervention while maintaining infrastructure simplicity.

AI summary
Systems and methods for replacing an existing advertisement in a digital video stream with replacement advertisements that are targeted to a user's characteristics include an ad policy manager receiving a notification of an existing advertisement in a video stream and identifying users watching the video stream as it is being broadcast by a broadcaster over a packet-switched network. The ad policy manager may then select one or more replacement advertisements unique to each user and instruct the broadcaster to transmit the selected replacement advertisement(s) in place of the existing advertisement, forming a replacement video stream that is unique to that user. The ad policy manager may then track the viewing of the replacement advertisement(s) in the replacement video stream.
