Cloud DVR Content Storage with Playback-Based Quality Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cloud DVR systems require large storage capacity due to users keeping content for extended periods without playback, necessitating unique copies for each user, leading to inefficient storage utilization.
Innovation Solution
A system that determines playback probability based on the duration of content storage and replaces higher quality portions with lower quality portions, such as those encoded with H.264/MPEG-AVC, H.265/MPEG-HEVC, or LV-EVC, to reduce storage space by removing high-resolution representations and enhancing layers, while maintaining playback quality through adaptive bitrate streaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unique copies of content are stored for every user that records the content, then each user can access their recorded content independently, but storage requirements increase significantly
Solution Approach 1:
The patent merges common content portions across multiple user recordings into a single shared copy in the cloud storage system. When multiple users record the same content, the system identifies identical or similar content segments and stores only one master copy, which is then referenced by all users. This eliminates redundant storage while ensuring each user can still access their recorded content independently through the shared copy.
Solution Approach 2:
The patent implements a universal content storage structure where a single stored content item serves multiple users simultaneously. The cloud-based recording system creates a unified content repository that functions for all users who record the same content, allowing the same storage space to serve multiple purposes and multiple users without requiring separate dedicated storage for each user's recordings.
2Duration of action of stationary object
If content is kept in storage for long periods without playback, then users have access to their recorded content, but storage efficiency decreases
Solution Approach 1:
The patent replaces traditional local DVR storage mechanics with a cloud-based system that uses intelligent content analysis and sharing mechanisms. Instead of physically storing complete copies locally for extended periods, the system uses cloud infrastructure with automated content identification, matching, and sharing capabilities that dynamically manage storage based on actual usage patterns and user needs.
3Reliability
If high-resolution content is stored for all recordings, then playback quality is maintained, but storage space requirements increase
Solution Approach 1:
The patent applies different quality levels to different portions of content based on their uniqueness and playback probability. Common content portions that are shared across multiple users are stored in a standardized efficient format, while user-specific customizations or less common portions maintain higher quality. This localized quality adjustment ensures playback quality where needed while optimizing storage space for shared content.

AI summary
Methods, apparatuses, and systems are described for reducing the amount of storage space required to store content item recordings. A content item may include one or more portions. A playback probability may be determined based on a duration of time a content item is stored in a storage location. One or more of the portions of the content item may be removed based on the playback probability associated with the content item.
