Hybrid Multicast Video Delivery for Dynamic Ad Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current advertisement technologies for dynamic video delivery, such as unicast server-side ad insertion, result in high costs and inefficiencies due to the need for multiple impressions to reach a wide audience, and lack flexibility in adjusting ad placement zones without extensive reconfiguration.
Innovation Solution
A computer-implemented video processing system that uses a single transport stream for ad delivery, combined with multiple manifest manipulations, allowing for dynamic ad insertion and reduced costs by making ad decisions once for multicast cohorts, and enabling flexible zone adjustments without full reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unicast server-side ad insertion is used to deliver advertisements dynamically, then ad placement flexibility is improved, but delivery cost increases substantially due to multiple impressions required to reach wide audience
Solution Approach 1:
The patent combines multicast and unicast approaches by using a single transport stream for video content delivered via multicast, while dynamically inserting advertisements through unicast manifest manipulations. This hybrid approach allows ad decisions to be made once for multicast cohorts rather than separately for each user, substantially reducing delivery costs while maintaining ad placement flexibility.
Solution Approach 2:
The system creates a universal ad delivery mechanism where a single ad decision serves multiple viewers in the same multicast cohort. The manifest manipulator unit can serve different audience segments (multicast cohorts, unicast users, hybrid users) using the same infrastructure, making the system multi-functional and cost-efficient.
2Loss of energy
If traditional broadcast infrastructure is used for regional or local ad variation, then ad delivery cost is reduced, but system complexity and reconfiguration requirements increase
Solution Approach 1:
The patent introduces dynamic ad insertion capabilities into the traditional broadcast infrastructure by manipulating manifests in real-time. Instead of requiring static pre-configuration of ad zones and regions, the system can dynamically adjust ad placements by modifying manifests for different user groups, reducing system complexity while maintaining cost efficiency.
Solution Approach 2:
The system segments users into different cohorts (multicast cohorts, unicast users, hybrid users) and applies different ad insertion strategies to each segment. This segmentation allows the system to maintain simplicity for large-scale multicast delivery while providing flexibility for targeted ad variations without requiring full system reconfiguration.
3Productivity
If multicast cohorts are used for ad delivery, then ad delivery efficiency is improved, but ability to adjust zone granularity without reconfiguration is reduced
Solution Approach 1:
The manifest manipulator unit enables dynamic adjustment of zone granularity by modifying manifests in real-time. Users can change the granularity of multicast cohorts (from broad regional zones to more granular segments) without requiring system reconfiguration, as the manifest can be manipulated to reflect different zone definitions and ad placement rules.
Data Source
AI summary
A video processing system for dynamic hybrid delivery of video is provided. The system includes a processor and a non-transitory data storage device storing a set of instructions, when executed by the processor, causes the system to: obtain a temporal data file indicating a start time and an end time for a video stream and one or more timing references, each of the timing references indicating a respective position in the video stream for advertisement placement; obtain a plurality of advertisement orders; generate, based on the temporal data file, a video configuration log file for dynamic insertion of one or more of the plurality of advertisement orders into the video stream; process the video stream using a video encoder to generate a transport stream based on the video stream; and generate a video output feed using the transport stream and the video configuration log file.
