Dynamic Bandwidth Allocation for Cable Video Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current switched digital video systems dynamically allocate bandwidth based on consumer demand, leaving untapped resources for advertisers and providers to exploit available bandwidth gaps for additional services like advanced advertising and content delivery on a 'push' basis.
Innovation Solution
Implementing a 'push' side dynamic bandwidth allocation system that monitors available bandwidth and reallocates it using a rules engine to fill gaps with value-added content, enabling simultaneous transmission of multiple advertising versions and expanded content delivery, while ensuring quality and reliability of primary services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bandwidth is dynamically allocated on a pull basis based on consumer demand, then network capacity is optimized for subscriber services, but available bandwidth gaps remain untapped for additional services
Solution Approach 1:
The system dynamically switches between pull-based and push-based bandwidth allocation modes. A bandwidth allocation manager monitors available bandwidth and can dynamically allocate unused bandwidth to advertising and other value-added services when pull-based demand is low, thereby resolving the contradiction between optimizing for subscriber services and delivering additional services.
Solution Approach 2:
The cable network infrastructure is designed to serve multiple functions: traditional subscriber video services, advertising delivery, and other value-added services. The system can multiplex different service types over the same network infrastructure, allowing the network to be universally used for various purposes depending on bandwidth availability.
2Reliability
If bandwidth is allocated exclusively to primary video services, then service reliability is maintained, but content variety and advertising opportunities are limited
Solution Approach 1:
The bandwidth allocation system segments available bandwidth into different pools: dedicated bandwidth for primary video services and shared bandwidth for advertising and value-added services. The segmentation manager divides the total available bandwidth and can dynamically adjust allocations, ensuring primary services maintain reliability while allowing advertising to utilize remaining capacity.
Solution Approach 2:
The system performs preliminary actions by pre-allocating bandwidth reserves for advertising and value-added services. When bandwidth becomes available from primary service reductions, these pre-configured allocations enable immediate deployment of advertising content without disrupting primary services, thus maintaining both reliability and variety.
3Productivity
If dynamic bandwidth allocation is implemented for video services, then network capacity is optimized, but system complexity increases
Solution Approach 1:
A bandwidth allocation manager acts as an intermediary component between the network infrastructure and service delivery systems. This dedicated manager handles the complexity of monitoring, calculating, and executing bandwidth allocations for both pull-based video services and push-based advertising, thereby simplifying the overall system architecture while maintaining optimization capabilities.
Solution Approach 2:
The system implements feedback mechanisms where the bandwidth allocation manager continuously monitors actual bandwidth usage and availability. Based on this feedback, the system automatically adjusts allocations between video services and advertising, optimizing network capacity utilization while reducing the need for complex manual configuration and control.

AI summary
Embodiments of the present invention include systems and methods enabling the send or “push” side of a cable transmission to dynamically obtain additional and/or temporary capacity. Bits and/or bandwidth of transmitted content is restricted by the service provider allowing gaps in the capacity to be filled with value-added content such as advertising, additional supplemental data feeds, or other media content.
