MDU Group Recording With Shared Content to Reduce Storage Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storing unique recordings for each user in a multi-dwelling unit (MDU) consumes excessive storage space, leading to potential storage overflow and increased costs due to the need for additional storage or deletion of old recordings.
Innovation Solution
Implement a method and device for group recording, where a single shared copy of content is recorded for multiple users based on common characteristics, using a MDU gateway device to predict target content items and manage storage efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unique copies of recordings are stored for each user in an MDU, then each user can access their own recording independently, but storage space is quickly consumed leading to storage overflow and increased costs
Solution Approach 1:
The patent merges multiple individual recording copies into a single shared recording stored in common storage. The system creates one master recording that multiple users can access simultaneously, eliminating the need for separate copies for each user while maintaining independent access capabilities through user authentication and permission management.
Solution Approach 2:
The shared recording serves multiple functions: it provides recording storage for all users, enables simultaneous access by multiple users, and reduces overall storage requirements. The single recording infrastructure supports diverse user needs without requiring individualized storage allocations.
2Reliability
If storage space is increased to accommodate unique copies for all users, then user access reliability is maintained, but system cost increases due to additional storage purchases
Solution Approach 1:
The patent combines multiple storage allocations into a single shared storage resource. By consolidating storage requirements, the system maintains full recording availability for all users while eliminating the need to purchase additional storage capacity that would be required if separate copies were maintained for each user.
Solution Approach 2:
Instead of creating physical copies of recordings for each user, the system creates digital references or pointers to the shared recording. Users access the same physical data through logical copies, maintaining recording availability without duplicating the actual stored content.
3Ease of operation
If old recordings are deleted to free up storage space, then storage management becomes simpler, but user access to historical content is lost
Solution Approach 1:
The shared recording infrastructure serves as a universal repository that preserves historical content for all users simultaneously. The system manages retention policies at the shared storage level, allowing historical recordings to be maintained without requiring individual management of multiple user-specific copies.
Solution Approach 2:
The system implements feedback mechanisms through user profiles and access logs that track which users need access to which historical recordings. This information feedback enables intelligent retention management, preserving content that is frequently accessed while managing storage of less-used historical recordings.

AI summary
Methods, systems, and devices for group recording are provided. In one example, a method includes: obtaining viewership data related to users of a multiple-dwelling unit (MDU), processing the viewership data to generate at least one user list that includes one or more common characteristics shared by the plurality of users, identifying at least one target content item, based on the one or more common characteristics for the at least one user list, determining at least one target recording item for group recording, based on the at least one target content item, automatically performing group recording of the at least one target recording item to correspondingly generate at least one shared recording, storing a copy of each shared recording in a storage device, and providing access to the content of the shared recording to a user of the MDU upon request by the user.
