Point-to-Point Media on Demand Server Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video-on-demand (VOD) systems face inefficiencies due to high processing and transmission demands on head end servers, as they handle individual title streaming for multiple customers, which can burden the system with other services like traditional TV programming and internet access.
Innovation Solution
Implementing a point-to-point VOD system where media content is stored at provider system hubs or servers, allowing content to be delivered from nearby hub servers rather than the head end server, and utilizing neighboring network-connected devices for content retrieval based on location and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual video titles are streamed from head end server to each customer, then video-on-demand service is provided, but processing capacity consumption at head end and transmission capacity consumption between head end and hub increase significantly
Solution Approach 1:
The patent segments the video content delivery function from the head end server and distributes it to multiple hub servers. Each hub server stores and delivers video titles to customers in its service area, eliminating the need for the head end server to handle individual title streaming requests. This segmentation reduces processing capacity consumption at the head end and transmission capacity consumption on the backbone network.
Solution Approach 2:
The patent implements local quality by deploying video content storage and delivery capabilities at distributed hub servers located closer to customers. Each hub server serves its local customer base, reducing transmission distances and optimizing resource utilization locally rather than relying on centralized head end server for all deliveries.
2Extent of automation
If head end server handles all VOD processing and transmission, then centralized control is maintained, but the head end server becomes inefficient and burdened with additional services
Solution Approach 1:
The patent segments the VOD service functions between head end server and hub servers. The head end server retains centralized control for content acquisition, catalog management, and authorization, while hub servers handle local content storage and delivery operations. This segmentation improves head end server productivity by eliminating routine streaming tasks.
Solution Approach 2:
The patent introduces hub servers as intermediary components between the head end server and customer premises. These intermediaries handle the burden of content delivery and processing, allowing the head end server to maintain centralized control without being inefficiently burdened by individual title streaming operations.

AI summary
Reducing head end server demand for cable television/services systems with point-to-point Media on Demand content delivery is provided. Upon receiving a request for media content, a content table may be requested from one or more neighboring network-connected devices to search for the requested content. If the requested content is found, the content may be provided to the requesting device from the neighboring device. If the requested content is not found on a neighboring device, a hub server station may be queried for the requested media content. The media content may be provided by the head end server if the content is not available on a neighboring device or the hub server. Embodiments may reduce demand on the head end server and free the head end server capacity for other uses.
