Network Recording Device Using Intermediary Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing recording/playing devices for broadcasting content face challenges with high manufacturing costs and space constraints due to the need for expensive Hard Disk Drives (HDDs), which limit their ability to efficiently record and play back content, especially in a networked environment where content distribution and sharing are desired.
Innovation Solution
A system that utilizes a network-connected recording/playing device with a communication interface to search for and combine content parts from distributed external resources, allowing for efficient recording, sharing, and playback of content without the need for local HDD storage, using a content locater management server to manage location and content information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a Hard Disk Drive (HDD) is installed in the broadcasting receiver for recording and playback functions, then the recording and playback capabilities are improved, but the manufacturing cost increases and the device becomes bulkier
Solution Approach 1:
The patent introduces a network as an intermediary medium between the broadcasting receiver and content storage. Instead of requiring a local HDD, the system uses network-connected storage devices (NAS, cloud storage, or external devices) to provide recording and playback functions remotely, thereby eliminating the need for expensive local storage hardware while maintaining functionality
Solution Approach 2:
The patent implements content copying over the network rather than requiring physical storage in the receiver. Content is copied to network storage devices and accessed remotely, allowing multiple users to access the same content without each needing their own storage hardware, thus reducing individual device costs
2Reliability
If a Hard Disk Drive (HDD) is installed in the broadcasting receiver for recording and playback functions, then the recording and playback capabilities are improved, but the device interior space is consumed and the device cannot be made slim
Solution Approach 1:
The network serves as a remote intermediary that provides storage capacity without occupying physical space within the receiver. By offloading storage functions to network-connected devices, the receiver can be designed with minimal internal storage requirements, enabling a slim form factor while maintaining full recording and playback capabilities through remote access
3Speed
If content is stored locally in the broadcasting receiver, then content access is fast, but the ability to share content across network is limited
Solution Approach 1:
The patent implements a universal content storage system where network-connected devices serve multiple functions: storage, sharing, and access. The same network storage infrastructure enables both fast local access for the primary user and remote access for multiple other users, making the system universally applicable for various user scenarios without requiring separate storage systems for each function
Data Source
AI summary
A device for recording and playing contents, a sever for managing content location information, an information recording medium, a method for managing content information, and a recording medium for the method are disclosed. The recording/playing device includes a communication interface unit configured to interface data transmission and reception with at least one external resource connected to a network and a controller configured to receive a request for a content, search for an external resource recording the requested content based on content identification information and control receiving the content from the searched external resource.
