Content Item Segmentation for Storage and Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content delivery systems face challenges in efficiently managing storage and bandwidth resources due to redundant storage and processing of content by multiple network devices, leading to potential quality issues in content output.
Innovation Solution
The method involves separating content items into chroma, luminance, and audio components, where the chroma component is stored on a central device with high storage capacity, and the luminance and audio components are stored on edge devices, reducing storage and bandwidth requirements.

Engineering Contradiction Analysis
1Speed
If content is redundantly stored and processed by multiple network devices, then content availability and access speed are improved, but storage resources and bandwidth resources are significantly increased
Solution Approach 1:
The content item is divided into multiple components (chroma component, luminance component, and audio component) with different storage requirements. The chroma component requiring more resources is stored on the head-end server, while the luminance and audio components requiring fewer resources are stored on the cable modem, eliminating redundant storage across multiple devices while maintaining efficient access.
2Reliability
If content is redundantly stored and processed by multiple network devices, then content availability is improved, but bandwidth resources are significantly increased
Solution Approach 1:
Content is segmented into components stored at different network locations (head-end server and cable modem). The system selectively retrieves components based on user requests, transmitting only necessary data through the network. This reduces bandwidth consumption compared to redundant full-content storage while maintaining content availability through distributed component storage.
3Quantity of substance
If chroma component is stored on central device and luminance/audio components are stored on edge device, then storage and bandwidth requirements are reduced, but system complexity is increased
Solution Approach 1:
The content item is divided into multiple components (chroma component, luminance component, and audio component) with different storage requirements. The chroma component requiring more resources is stored on the head-end server, while the luminance and audio components requiring fewer resources are stored on the cable modem, eliminating redundant storage across multiple devices while maintaining efficient access.
Solution Approach 2:
The user device acts as an intermediary that receives and synchronizes components from different storage locations (head-end server and cable modem). This intermediary function manages the complexity of coordinated retrieval and assembly of distributed content components, abstracting the storage distribution complexity from the overall system.

AI summary
Methods and systems for managing content items are described. A content item may be separated into components, such as chroma components, luminance components, and audio components. For more efficient management of the content, including for storage and delivery of the content, the separate components may be stored at different locations. For example, chroma components may be stored on a central server, while luminance and audio components are stored at other locations, such as edge servers, or vice versa, to accommodate network efficiency considerations. When content is delivered to a player, two or more separate streams carrying different content components may be delivered to the player.
