DOCSIS Bandwidth Management via Staggered Ad Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In linear broadcasting, the demand for network resources during advertisement times exceeds available bandwidth, particularly due to concurrent unicast requests for targeted advertisements, leading to insufficient bandwidth for both television and internet services.
Innovation Solution
A system that allocates addressable advertisement slots across different channels to avoid overlapping requests, evaluates audience segments for predicted bandwidth needs, and uses audience spot division multiplexing and bandwidth dial-up techniques to manage and optimize DOCSIS bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple concurrent unicast requests for targeted advertisements are provided during advertisement times of different broadcasted programs, then advertisement delivery capability is improved, but network bandwidth consumption increases beyond available resources
Solution Approach 1:
The patent segments the broadcast audience into multiple audience segments and divides advertisement delivery into multiple unaligned time slots. Each audience segment receives advertisements at different times rather than simultaneously, which segments the bandwidth demand across time to prevent overwhelming the network capacity during any single moment while still delivering targeted ads to all segments.
2Adaptability or versatility
If addressable advertisements are provided to multiple devices concurrently during the same advertisement slot, then targeted advertising effectiveness is improved, but DOCSIS bandwidth demand exceeds available bandwidth
Solution Approach 1:
The patent implements periodic action by scheduling advertisement delivery in repeated cycles with different time slot assignments for different audience segments. Each segment receives ads periodically but at staggered times within each cycle, creating a rhythmic pattern of bandwidth usage that prevents sustained peak demand while maintaining continuous targeted advertising coverage across all segments.
Solution Approach 2:
The patent adds a time dimension to advertisement delivery by unaligning the time slots for different audience segments. Instead of delivering ads to all segments simultaneously (same time dimension), the system distributes delivery across multiple time dimensions, effectively transforming a single-point bandwidth conflict into a distributed temporal pattern that fits within available bandwidth constraints.
3Ease of operation
If advertisement slots are aligned across multiple LSA channels, then advertisement scheduling simplicity is improved, but bandwidth demand at specific nodes increases due to overlapping unicast requests
Solution Approach 1:
The patent applies asymmetry by deliberately misaligning advertisement time slots for different LSA channels and audience segments. Instead of using symmetric, aligned time slots that cause simultaneous bandwidth demands at network nodes, the system employs asymmetric, staggered time slot assignments that distribute bandwidth demand more evenly across the network infrastructure, reducing peak demands at any single node.

AI summary
This disclosure describes systems, methods, and devices related to network resource management and content delivery. A method may include a first device determining a first bandwidth demand associated with a second device sending a first addressable advertisement using a data over cable service interface specification (DOCSIS) bandwidth using a first advertisement spot for a first linear segment addressability (LSA) television channel, and determining a second bandwidth demand associated with the second device sending a second addressable advertisement using the DOCSIS bandwidth for presentation using a second advertisement spot. The method may include determining that the first bandwidth demand is below a threshold bandwidth, and determining that the second bandwidth demand exceeds the threshold bandwidth. The method may include sending a reference to the first addressable advertisement over the DOCSIS bandwidth for presentation using the first advertisement spot and, and determining a recommendation associated with presentation of the second addressable advertisement.
