Dynamic Targeted Ad Delivery via Unused Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cable TV advertising methods are inefficient as they lack precision in targeting advertisements to the actual audience watching a program, leading to wasted ad space and high costs in maintaining software applications on set-top terminals.
Innovation Solution
The system dynamically identifies set-top terminals currently receiving a program channel and generates targeted advertisements based on demographic data, transmitting these during advertisement breaks on unused transmission channels, ensuring that only relevant ads are shown to the appropriate audience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If targeted advertisements are delivered using prior art techniques with pre-prepared ad streams, then advertisement delivery is possible, but the accuracy of targeting is low because the cable operator does not know the actual audience composition at the time of advertisement break
Solution Approach 1:
The system dynamically determines the actual audience composition at the time of advertisement break by monitoring which program channels are currently being received by set-top terminals. This dynamic approach replaces static pre-prepared advertisement streams with real-time audience-based targeting, allowing the cable operator to identify exactly who is watching and deliver relevant advertisements accordingly.
2Adaptability or versatility
If software applications are installed and maintained on numerous set-top terminals for targeted advertising, then targeted advertisement delivery is enabled, but the cost and complexity of maintenance increases significantly
Solution Approach 1:
The invention extracts the complex software processing requirements from the set-top terminals and relocates them to the cable operator's headend facility. The STTs only need to transmit basic reception status information, while all audience analysis, demographic matching, and advertisement selection is performed centrally by the cable operator's system, dramatically reducing terminal complexity and maintenance burden.
Solution Approach 2:
The cable operator's headend system acts as an intermediary between the program channels and the set-top terminals. It receives program reception information from STTs, determines actual audience composition, selects appropriate targeted advertisements, and delivers them back to the relevant STTs. This intermediary approach centralizes intelligence and simplifies terminal functions.
3Productivity
If advertisement streams are prepared in advance without knowledge of actual audience, then advertisement delivery is possible, but ad space is wasted when demographic groups are not present in the actual audience
Solution Approach 1:
The system implements a feedback loop where set-top terminals continuously report which program channels they are currently receiving to the cable operator's headend. This real-time feedback information about actual program consumption is used to dynamically determine audience composition and select appropriate targeted advertisements, ensuring ad space is only used when the target demographic is actually present and watching.
Data Source
AI summary
When an advertisement break is detected on a program channel stream, demographic data is obtained which is descriptive of the subscribers who are currently watching material from the program channel stream, and one or more streams containing substitute advertisements are generated based on the demographic data. The substitute advertisements in each stream, thus generated, are targeted at a different demographic group of the subscribers. The number of substitute advertisement streams corresponds to the number of unused transmission channels allocated for transmission of such streams. Groups of subscribers' set-top terminals (STTs) are directed to tune to the allocated transmission channels during the advertisement break to receive the substitute advertisement streams, respectively. Consequently, the subscribers are shown the substitute, targeted advertisements instead of the regularly-scheduled advertisements.
