DVR Media Content Transfer via External Storage Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are reluctant to upgrade digital media recording devices like DVRs because they cannot transfer media content to new devices, resulting in lost revenue for manufacturers and missed features for users.
Innovation Solution
A method for transferring media content from a first DVR to a second DVR using external storage, where media content is copied from internal storage to external storage and then transferred to the new device, with encryption and decryption schemes ensuring compatibility and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media content is stored on internal storage of a DVR, then media content can be stored and accessed, but the ability to transfer content to a new device is lost during upgrade
Solution Approach 1:
The patent introduces an intermediary storage device that acts as a bridge between the old DVR and the new DVR. This external storage medium temporarily holds the media content during the transfer process, enabling seamless migration without requiring direct connection or complex integration between the two DVRs. The intermediary device simplifies the transfer mechanism while maintaining content integrity.
2Reliability
If encryption schemes are implemented for media content transfer, then security and compatibility are improved, but transfer complexity and processing time increase
Solution Approach 1:
The patent implements preliminary encryption of media content on the external storage device before transfer. By pre-processing the encryption in advance, the system ensures that content is already secured and formatted for compatibility with the new DVR, reducing the processing time required during actual transfer operations. This advance preparation minimizes the time penalty associated with security measures.

AI summary
Systems and methods for media content transfer are described. One exemplary embodiment of a method for transferring content from a first digital video recorder (DVR) set-top to a second DVR set-top includes recording instances of media content to a first storage medium located internal to a housing of the first DVR set-top and receiving an indication that the instances of media content stored to the first storage medium are to be made available for playback using the second DVR set-top. One exemplary method further includes, in response to receiving the indication that the instances of media content stored to the first storage medium are to be made available for playback using the second DVR set-top, providing the instances of media content to the second DVR set-top over a communication interface of the second DVR set-top, the communication interface accessible from an external port of the second DVR set-top.
