Video Scene Metadata Packaging for Encrypted Immersive Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices face challenges in providing enhanced audio and visual immersion for content consumption due to limited processing power and encryption limitations, making it difficult to analyze video content for supplemental data generation.
Innovation Solution
Supplemental data, such as timed metadata, is generated at a server before encryption, using AI and machine learning to analyze video content, and is packaged with the media stream to control ambient lighting, scent, and haptic devices, overcoming processing and encryption limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is analyzed in real-time at the device to generate supplemental data, then the entertainment experience is enhanced, but the device processing power is overwhelmed
Solution Approach 1:
The patent applies preliminary action by generating supplemental data from video content at a server before the content is distributed to client devices. The server performs the computationally intensive video analysis and metadata generation in advance, so that when the encrypted video content is delivered to client devices, the supplemental data is already available and does not require real-time processing at the device, thus resolving the contradiction between enhancing entertainment experience and preserving device processing power
Solution Approach 2:
The patent introduces a server as an intermediary between the video content source and the client devices. This intermediary server performs the video analysis and supplemental data generation, acting as a mediator that handles the computational burden away from client devices. The server processes the video content, generates timed metadata, and delivers both the encrypted video and supplemental data to client devices, thereby resolving the processing power contradiction
2Reliability
If video content is analyzed after encryption to generate supplemental data, then content security is maintained, but data generation becomes infeasible
Solution Approach 1:
The patent applies preliminary action by performing video content analysis and supplemental data generation at the server before encryption is applied to the video content. Since the server has access to the unencrypted content during the metadata generation process, it can easily analyze the video and create timed metadata. After this preliminary action, the video content is encrypted for secure distribution, thus resolving the contradiction between maintaining content security and enabling easy supplemental data generation
Solution Approach 2:
The patent inverts the conventional approach by generating supplemental data from unencrypted content before encryption, rather than attempting to analyze encrypted content afterward. This inversion allows the system to easily generate metadata when the content is accessible, then apply encryption for security, thus resolving the contradiction between content security and data generation feasibility
Data Source
AI summary
Systems, apparatuses, and methods are described for generating supplemental data that may be contemporaneous with audio or video content and that may be shared with, and used by, a player and connected devices. To overcome limitations on computing power and the need for external hardware at the player, encryption of the audio or video content may be performed subsequent to the generation of the supplemental data and over the entire duration of the content. The encrypted content along with the supplemental data may be provided, in a packaged content file, to the player to enhance the experience of a user of the content.
