Content Delivery Queue Prioritization for Broadcast Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Broadcast systems face challenges in reliably delivering content files due to bandwidth limitations, local signal interruptions, and network outages, particularly in satellite and internet-based transmission, which affect real-time applications like radio broadcasts, and lack the capability to automatically prioritize and sort content for timely delivery.
Innovation Solution
A system and method that prioritize and sort content files by type into delivery queues with specific priorities, allowing for timely delivery over satellite, internet, or combined networks, with the ability to adjust priorities and substitute content files as needed, ensuring higher priority content is delivered first.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If satellite transmission is used for content delivery, then coverage area is improved, but reliability deteriorates due to bandwidth limitations and local signal interruptions
Solution Approach 1:
The system combines satellite transmission and internet transmission into a unified content delivery system. The headend can select from multiple transmission paths (satellite only, internet only, or combination) to deliver content files to affiliate systems, thereby maintaining reliability while preserving the broad coverage advantage of satellite transmission.
2Reliability
If internet transmission is used for content delivery, then reliability is improved, but speed deteriorates due to latency issues
Solution Approach 1:
The system dynamically adjusts transmission parameters and path selection based on real-time network conditions. The headend can modify transmission priorities, switch between satellite and internet paths, and adjust content delivery timing to optimize both speed and reliability according to current network status.
3Device complexity
If content files are delivered without prioritization, then device complexity is reduced, but loss of time increases due to inability to ensure timely delivery of high priority content
Solution Approach 1:
The system performs preliminary prioritization and sorting of content files at the headend before transmission. Content files are categorized into different priority levels (e.g., high priority for breaking news, low priority for routine updates) and queued accordingly, ensuring that high-priority content is transmitted first without requiring complex real-time decision-making at affiliate systems.
4Ease of operation
If transmission priority cannot be modified, then ease of operation is improved, but adaptability deteriorates due to inability to respond to changing content delivery requirements
Solution Approach 1:
The system provides dynamic priority adjustment capabilities where transmission priorities can be modified in real-time based on changing requirements. The headend can update priority levels for different content files or affiliate systems, and the system automatically reconfigures transmission queues and paths to accommodate these changes, maintaining operational simplicity while enhancing adaptability.

AI summary
Methods, systems and computer program products are provided for prioritizing content delivery. Content files associated with one of a plurality of content types are received and saved in one of a plurality of delivery queues according to the content type of the content file where each delivery queue is associated with a priority. In turn, the content files saved in the plurality of delivery queues are delivered over one or more networks to one or more affiliate systems. The transmission order of the content files is based on the priority of the delivery queue.
