HD/SD Content Allocation Under Media Network Bandwidth Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media networks face inefficiencies and increased costs due to the need to increase resource utilization, such as bandwidth, to accommodate different content formats, leading to decreased profitability in delivering multiple programming formats.
Innovation Solution
Adaptive bandwidth management systems that dynamically allocate resources by prioritizing and transcoding content elements to ensure delivery of all content assets, optimizing the use of existing bandwidth and reducing the need for additional transport streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If bandwidth is increased to accommodate HD content, then content quality is improved, but network resource utilization efficiency deteriorates
Solution Approach 1:
The system dynamically adjusts content delivery parameters based on available network resources. When bandwidth is insufficient for HD content, the system automatically transitions to delivering lower-profile versions (SD content) of the same program, optimizing resource utilization while maintaining acceptable content quality for all viewers.
Solution Approach 2:
The invention changes the delivery parameters (bandwidth allocation, content profile) based on network conditions. By monitoring available resources and adjusting the profile of transmitted content accordingly, the system achieves efficient resource utilization while ensuring all content can be delivered to viewers.
2Adaptability or versatility
If multiple content formats are transmitted simultaneously, then content versatility is improved, but device complexity increases
Solution Approach 1:
A single transport stream is designed to carry multiple content profiles (HD and SD) simultaneously, making the network infrastructure universal. The same stream can serve different viewer needs without requiring separate dedicated streams for each format, reducing overall system complexity.
Solution Approach 2:
The content stream is segmented into different profiles or layers (HD profile and SD profile) within a single transport stream. This segmentation allows the system to deliver multiple content formats through one unified infrastructure, reducing the complexity of managing separate networks while maintaining versatility.
3Reliability
If bandwidth is allocated to ensure delivery of all content assets, then content delivery reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The system allocates bandwidth in a prioritized manner, ensuring delivery of essential content assets first. When resources are constrained, lower-profile content receives reduced allocation or is delivered only when capacity allows, ensuring reliable delivery of critical content while optimizing overall resource utilization efficiency.

AI summary
Systems, methods and computer-readable storage media for allocating content elements addressed for a content opportunity in a transport stream within a household-addressable media network. A content opportunity may include an advertising slot in a programming stream. The content elements may include advertising content configured to be run during the advertising slot. The advertising slot may be transmitted in a programming stream providing television programming and the advertising content may be provided in a commercial feed. The media network may be configured to transmit various content formats, such as high definition (HD), standard definition (SD), and variations thereof. Systems may be configured to allocate the highest profile corresponding content elements if there is sufficient resources available. If sufficient resources are not available, the system may allocate lower profile versions of the content elements.
