Screen Recording Notification for Digital Rights Management

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Screen recording functionality on computing devices can bypass digital rights management protections, and existing methods for remote screen recording require direct wired connections, which are cumbersome and inflexible.

Innovation Solution

A computing device notifies media applications when screen recording is in progress, allowing them to modify content and prevent unauthorized recording, and enables remote screen recording over a network by detecting and communicating with other devices, presenting indicia of recording in progress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If screen recording functionality is implemented to allow remote recording of display screens, then ease of operation is improved, but digital rights management protections are compromised

Engineering Contradiction:

Improveease of screen recordingVSAvoidbypass of digital rights management

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by notifying the media application before screen recording begins. The computing device detects when media content is being sent to a second destination and sends a notification to the media application in advance, allowing the application to take protective measures before the harmful recording action occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring screen recording activity and communicating status back to the media application. The computing device detects screen recording in progress and sends notifications to the media application, enabling real-time response and content modification to prevent unauthorized recording.

Inventive Principle:

Principle #23Feedback

2Reliability

If direct wired connections are required for remote screen recording, then reliability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveconnection stabilityVSAvoidconnection setup complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system replaces the mechanical wired connection system with a wireless network-based communication system. Instead of requiring physical cables and direct connections between devices, the invention uses network protocols to transmit screen content and control signals wirelessly, eliminating the need for physical infrastructure while maintaining communication reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

In some implementations, a computing device can notify a media application when a screen recording may be in progress. For example, the computing device can be configured to send media content provided by the media application for presentation on the display of the computing device to a second destination (e.g., a file, a remote playback device, a remote recording device, etc.) that may result in a recording of the display screen of the computing device. To allow the media application an opportunity to protect the media content from unauthorized recording, the computing device can notify the media application that the media content being sent to the second destination may be recorded. In response to receiving the notification, the media application can modify the presentation of the media content to prevent or downgrade any recording that may be performed.
