Live Video Streaming Metadata for Consistent HDR and Audio Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Broadcasters face challenges in maintaining the accuracy and creative intent of audiovisual content due to uncontrollable modifications during transmission and device-specific rendering, leading to inconsistent and inaccurate display of colors, brightness, and sound across different devices.
Innovation Solution
A system that uses content containers with metadata to specify output configurations, employing upscaling, upmapping, and upmixing techniques to ensure that broadcast content is delivered in a manner closest to the creator's intent, utilizing a cloud-based transformation pipeline to convert SDR content into HDR/Dolby Atmos® without requiring production infrastructure upgrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If device-specific rendering methods are used to optimize display, then display quality may be improved for each device, but consistency across different devices deteriorates
Solution Approach 1:
The patent introduces a cloud-based transcoding service as an intermediary between the broadcast facility and user devices. This intermediary performs content adaptation and transformation in the cloud, applying consistent processing rules across all devices while accounting for their specific capabilities, thereby maintaining both accuracy and consistency.
Solution Approach 2:
The system performs content transformation and adaptation in advance at the cloud level before content reaches the user device. By pre-processing and normalizing the content with appropriate metadata in the cloud, the system ensures consistent rendering across different devices without requiring complex processing at the device level.
2Manufacturing precision
If broadcasters control content output configuration settings, then creative intent accuracy is improved, but device capability constraints worsen
Solution Approach 1:
The patent implements dynamic content adaptation where the cloud-based transcoding service adjusts content parameters in real-time based on the capabilities of the receiving device. The system maintains creative intent accuracy by applying appropriate transformation parameters while adapting to varying device capabilities through dynamic configuration.
Solution Approach 2:
The system changes content parameters such as color space, dynamic range, and encoding format based on device capabilities. By transforming content parameters in the cloud according to target device specifications, the system achieves both creative intent accuracy and device adaptability.
3Manufacturing precision
If cloud-based transformation pipeline is used for upscaling and upmapping, then content fidelity is improved, but processing complexity is transferred from device to cloud
Solution Approach 1:
The cloud-based transcoding service acts as an intermediary that handles complex content transformation tasks. By moving processing complexity to this dedicated intermediary service, user devices only need to handle basic playback functions, significantly reducing device complexity while maintaining high content fidelity through professional-grade cloud processing.

AI summary
Systems and methods are disclosed for maintaining the accuracy and/or creative intent of broadcast content. One method comprises receiving broadcast content from one or more data stores, wherein the broadcast content includes video data and audio data, and wherein the video data includes a plurality of frames, analyzing at least one of the plurality of frames to determine at least one display attribute, based on the analyzing, creating, via a transcoder, metadata corresponding to the at least one display attribute, updating, by the one or more processors, the broadcast content by attaching the metadata to the at least one of the plurality of frames of the broadcast content, and transmitting the updated broadcast content to a device, wherein the device is configured to output the broadcast content based on the metadata.
