Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current digital television recording systems, particularly those using IP channels, face inefficiencies in server space consumption and network resources due to cloud-based storage and streaming requirements, as well as digital rights management rules that necessitate separate content copies for each user.

Innovation Solution

A media client device capable of processing both QAM and IP channels, which allows users to record content locally by obtaining a tokenized source URL, storing encrypted content in memory, and decrypting it using a device-specific key, thereby reducing server space and network resource consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cloud-based storage system is used to store encrypted content, then content security is improved, but server space consumption increases

Engineering Contradiction:
Improvecontent securityVSAvoidserver space
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent applies the copying principle by enabling the media client device to store encrypted content locally in its memory rather than relying solely on cloud-based storage. The system creates a local copy of the content on the client device while maintaining encryption, allowing the content to be accessed and played back without continuously consuming server space. This resolves the contradiction by duplicating the storage function from cloud-based to device-based, reducing server space requirements while maintaining content security through encryption.

Inventive Principle:
Principle #26Copying

2Reliability

If cloud-based storage system is used to store encrypted content, then content security is improved, but network resources consumption increases

Engineering Contradiction:
Improvecontent securityVSAvoidnetwork resources
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies the copying principle by enabling the media client device to store encrypted content locally in its memory rather than relying solely on cloud-based storage. The system creates a local copy of the content on the client device while maintaining encryption, allowing the content to be accessed and played back without continuously consuming server space. This resolves the contradiction by duplicating the storage function from cloud-based to device-based, reducing server space requirements while maintaining content security through encryption.

Inventive Principle:
Principle #26Copying

3Reliability

If separate content copies are stored for each user per DRM rules, then content rights protection is improved, but server space consumption increases

Engineering Contradiction:
Improvecontent rights protectionVSAvoidserver space
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent applies the copying principle by enabling the media client device to store encrypted content locally in its memory rather than relying solely on cloud-based storage. The system creates a local copy of the content on the client device while maintaining encryption, allowing the content to be accessed and played back without continuously consuming server space. This resolves the contradiction by duplicating the storage function from cloud-based to device-based, reducing server space requirements while maintaining content security through encryption.

AI summary

A media client device, including a memory and capable of processing Quadrature Amplitude Modulation (QAM) channels and IP channels, may receive a recording request to record content on an Internet Protocol (IP) channel. The media client device may provide, to a first device, a source Universal Resource Locator (URL) corresponding to the content, and receive, from the first device, encrypted content (e.g., an encrypted version of the content). The media client device may store, in the memory, the encrypted content, and provide, to a second device, information regarding the encrypted content to permit the second device to generate and store a license and a key. The media client device may receive a playback request to play the content, and obtain, from the second device, the license and the key. The media client device may decrypt, using the license and the key, the stored, encrypted content to obtain the content.
