Content Segment Group File for Reducing Network Transfer Burdens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cloud or network digital video recorder (DVR) systems face inefficiencies in storing, accessing, and delivering user-specific recorded content due to redundant storage of similar content files, which burdens computing resources with significant storage and transfer demands.
Innovation Solution
The system employs a content segment group file approach, where recorded content is split into user-specific and common segments, allowing for efficient storage and transfer by recreating the original content using a user-specific content segment and a common content segment, or by using a content segment group file, thereby reducing redundant storage and transfer burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user-specific recorded content is stored individually for each user, then user content privacy and access control requirements are satisfied, but computing resources are burdened with significant storage and transfer demands due to redundant storage of similar content files
Solution Approach 1:
The patent segments recorded content into distinct components: user-specific portions (unique to each user's recording) and common portions (identical across multiple users' recordings of the same content). This segmentation allows the system to store only one copy of common content while maintaining individual user access rights, thereby reducing overall storage demands while preserving privacy and access control requirements.
Solution Approach 2:
The patent merges multiple users' recorded content by identifying and consolidating common portions into a single shared storage location. When multiple users record the same program, the common segments are combined into one master copy, and users access their content through references to this shared copy combined with their unique user-specific segments, eliminating redundant storage while maintaining individual access control.
2Reliability
If complete content files are stored for each user recording, then individual user access and content integrity are maintained, but network bandwidth and processing power are consumed by transferring and managing redundant copies of similar content
Solution Approach 1:
The patent creates virtual copies of user content by combining references to shared common content segments with user-specific segments. Instead of physically duplicating entire content files for each user, the system generates on-demand reconstructions of individual user recordings by assembling the appropriate combination of common and user-specific portions, thereby maintaining content integrity and individual access while minimizing actual data copying and network transfer.
3Ease of operation
If redundant content segments are stored for each user, then individual user content requirements are met, but storage capacity is wasted and system efficiency decreases
Solution Approach 1:
The patent implements a universal storage structure where common content segments serve multiple users simultaneously. A single common content segment can be referenced and combined with different user-specific segments to satisfy the content requirements of multiple users, making the storage system multi-functional and highly efficient. This universal approach maintains ease of user access while dramatically improving overall system productivity by eliminating redundant storage.
Data Source
AI summary
Systems and methods are described herein for moving content across a network by replicating compressed video segments. Data transfer burdens on the network may be reduced by only moving residual data associated with an original segment (e.g., an original recording) across the network and using the residual data to recreate the original segment. According to some aspects, the original segment may be decoded from the residual with a private key.
