Segmented Content Delivery via Edge Reconstitution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional content delivery networks face limitations in efficiently delivering content to end users due to bandwidth constraints, lack of time-shifting capabilities, and inability to provide personalized content, especially in edge devices, which often result in denial of service and are restricted to specialized client devices.
Innovation Solution
A method and system that segment content into chunks for delivery through a content delivery network, allowing reconstitution at edge devices for on-demand viewing, time-shifted playback, and personalized content delivery, using an encoder/transcoder to convert content into multiple formats and bitrates, and a segmentor to parse content into segments with dynamic playlist generation and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is delivered in all or nothing fashion through conventional networks, then bandwidth utilization is simplified, but service denial occurs when bandwidth limitations are reached at edge devices
Solution Approach 1:
The patent segments content into multiple chunks that can be delivered independently through the content delivery network. This allows partial content delivery when bandwidth is limited, preventing complete service denial while maintaining efficient bandwidth utilization through selective chunk transmission and reconstitution at edge devices.
2Productivity
If switched digital video techniques are used to multicast content to edge devices, then content delivery efficiency is improved, but time-shifting operations cannot be executed and personalized content cannot be delivered
Solution Approach 1:
By segmenting content into deliverable chunks, the system enables edge devices to receive and store specific segments independently, allowing time-shifting operations where users can pause, rewind, or fast-forward content. Personalization is achieved by selectively delivering different content segments to different users based on their preferences and behavior.
Solution Approach 2:
Content chunks are pre-processed and made available in the content delivery network before user requests. This preliminary preparation enables edge devices to quickly access and deliver content segments on-demand, supporting time-shifting capabilities without requiring real-time processing at the edge.
3Device complexity
If conventional content delivery is used, then system complexity is reduced, but only specialized client devices can support the functionalities
Solution Approach 1:
Segmenting content into standardized chunks with uniform formatting enables generic client devices to process and display content without requiring specialized hardware or software. The segmentation approach creates a universal interface that simplifies the client device requirements while expanding compatibility across different device types.

AI summary
Disclosed systems and methods relate to segmented delivery of content. In one aspect, the segmentation process allows discrete segments of content to be moved through a content delivery network for reconstitution at an edge device. In addition, aspects of the disclosure provide for personalized delivery of content (e.g., advertising, etc.) to each end user and for bandwidth optimization by delivering format specific content based on the capability of an end user device. In yet other aspects, the methods and systems disclosed herein may support time-shifted viewing of live programming options and for adaptive bit rate transmission of content to user devices.
