MPEG-DASH Media Presentation Descriptors for Repeat Ad Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media delivery systems face challenges in efficiently inserting and managing regional and local advertisements within national media streams, particularly in digital television and video on demand systems, without disrupting the viewing experience.
Innovation Solution
A system and method for scheduling MPEG-DASH events that utilize an advertisement splicer to insert advertisements based on cue messages, allowing for dynamic insertion of regional or local ads within national media streams, optimizing ad placement and viewer experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advertisements are inserted into media streams at multiple regional and local levels, then ad relevance and viewer engagement are improved, but system complexity and difficulty of managing ad insertion increases
Solution Approach 1:
The patent segments the advertisement insertion system into distinct hierarchical levels (national, regional, local) with specific cue messages at each level. This segmentation allows the system to manage complex multi-level ad insertion by breaking it down into manageable, independent components that can be processed separately at each geographic level.
Solution Approach 2:
The patent introduces cue messages as intermediary signals that coordinate advertisement insertion across different levels. These cue messages act as mediators between the national, regional, and local ad systems, enabling seamless integration without requiring complex direct communication between all system components.
2Measurement precision
If advertisements are dynamically inserted based on user profiles and media content ratings, then ad targeting precision is improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary actions by pre-establishing cue message schedules and ad insertion points in the media stream before actual advertisement delivery. User profiles and content ratings are processed in advance to determine which ads should be inserted at specific cue points, reducing real-time processing requirements.
Solution Approach 2:
The patent implements dynamic advertisement insertion that adapts to real-time conditions while maintaining efficiency. The system dynamically selects and inserts ads based on current user profiles and content ratings, but does so at pre-determined cue message points rather than continuously, balancing precision with processing efficiency.
3Adaptability or versatility
If regional and local advertisements are inserted within national media streams, then local market coverage is improved, but risk of disrupting media stream continuity increases
Solution Approach 1:
The patent applies local quality by inserting region-specific and local-specific advertisements at appropriate cue message points within the national media stream. Each level of advertisement (national, regional, local) is tailored to its specific geographic market while maintaining compatibility with the overall stream structure, ensuring local relevance without compromising stream integrity.
Solution Approach 2:
The patent employs beforehand cushioning by carefully planning and scheduling ad insertion points at cue messages that are strategically positioned within the media stream. This advance planning ensures that ad insertions occur at natural break points or transition areas, cushioning against potential disruptions to stream continuity and maintaining smooth playback.

AI summary
A method for indicating repeat occurrences of advertisements in media content may include one or more of the following. The method may include inserting a first descriptor element for a media content in a media presentation description (MPD) associated with the media content. The method may include inserting a second descriptor element for a repeat occurrence of the media content in the MPD. The second descriptor element may indicate that, during the repeat occurrence of the media content, the media content be presented from thegbeginning.
