DVR Storage Transfer for Cross-Device Program Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Limited storage space on recording devices, such as digital video recorders (DVRs), often results in older programs being automatically deleted to make room for newer recordings, leading to inefficiencies in managing television program storage.
Innovation Solution
A system and method for managing television program storage across multiple recording devices, allowing portions of programs to be stored locally and remotely, with conflict resolution and data transfer mechanisms to optimize storage utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If programs are stored locally on a single recording device, then access speed and availability are improved, but storage space is limited and older programs are automatically deleted
Solution Approach 1:
The patent segments the storage system into local recording devices and remote storage systems. Local devices store frequently accessed or recent programs for immediate availability, while remote systems store older or less frequently accessed programs. This segmentation allows the system to maintain high program availability locally while utilizing abundant remote storage space to prevent automatic deletion of older content.
2Quantity of substance
If multiple recording devices are used to increase storage capacity, then storage space is improved, but system complexity increases
Solution Approach 1:
The patent introduces a centralized management system that acts as an intermediary between multiple recording devices and the user. This management system handles storage allocation, data transfer coordination, and conflict resolution automatically, allowing multiple devices to work together as a unified storage pool without requiring users to manually manage each device's content or complexity.
3Productivity
If programs are distributed across multiple devices, then storage efficiency is improved, but data management and conflict resolution become more difficult
Solution Approach 1:
The patent implements feedback mechanisms where the management system continuously monitors storage status across all recording devices, program access patterns, and conflicts. Based on this feedback, the system automatically makes decisions about data transfer, storage allocation, and conflict resolution, eliminating the need for manual data management while optimizing storage efficiency dynamically.
4Duration of action of stationary object
If old programs are kept in local storage, then content retention is improved, but available space for new recordings decreases
Solution Approach 1:
The patent adds a temporal and spatial dimension to storage by introducing remote storage systems that act as an extended archive. Older programs are automatically migrated from local to remote storage, freeing up local space for new recordings while preserving historical content in the remote dimension. This creates a multi-layered storage architecture where different time periods and access frequencies are handled at different storage levels.
Data Source
AI summary
According to one embodiment, a method includes receiving a request to transfer a stored representation of a television program from a first recording device to a second recording device; and transferring the stored representation from the first recording device to the second recording device, where the representation is stored on the second recording device and made available for later output.
