Video Enhancement via Hierarchical Metadata Sidecar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video content systems face challenges in enhancing video quality without increasing data size and ensuring compatibility across different devices, as modifications are typically made at the server and may not be properly decoded or displayed by all receiving devices.
Innovation Solution
A method and apparatus that receive video content and metadata with a hierarchical order of metadata fields, allowing for enhancement operations to be performed on specific portions of the video content according to settings associated with these fields, thereby enhancing video quality at the device rather than the server, reducing data transmission requirements and ensuring compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If enhancement operations are performed at the server and embedded into video content, then video quality can be improved, but data size substantially increases
Solution Approach 1:
The patent extracts enhancement operations from the video content data stream and places them in separate metadata sidecar files. This separation allows the video content to be transmitted in its original format without embedded modifications, while enhancement parameters are stored independently. The receiving device then applies these enhancement operations locally, achieving improved video quality without increasing the transmitted data size.
Solution Approach 2:
The patent segments the video delivery system into two independent components: the original video content and separate enhancement metadata. This segmentation allows the video content to remain compact while enhancement operations are defined separately in structured metadata fields, enabling quality improvement without proportionally increasing data transmission requirements.
2Manufacturing precision
If enhancement operations are embedded into video content, then video quality can be improved, but compatibility across different receiving devices decreases
Solution Approach 1:
The patent creates a universal metadata schema that can be interpreted by various receiving devices regardless of their specific capabilities. The structured metadata fields define enhancement operations in a standardized format that multiple device types can process, allowing the same video content with metadata to be enhanced across different platforms while maintaining compatibility.
Solution Approach 2:
The patent introduces structured metadata as an intermediary layer between the video content and the receiving device. This metadata acts as a communication bridge, conveying enhancement instructions in a standardized format that devices can interpret without requiring direct embedding of complex enhancement algorithms in the video stream itself, thereby improving cross-device compatibility.
3Ease of operation
If user-adjustable settings are applied to all video content, then individual user preferences can be accommodated, but the complexity of settings management increases
Solution Approach 1:
The patent implements dynamic enhancement where metadata fields can be selectively applied based on user preferences and device capabilities. Rather than static global settings, the system dynamically determines which enhancement operations to apply by evaluating user-adjustable parameters against the structured metadata, allowing flexible preference management without proportional increases in system complexity.

AI summary
Various aspects of methods and apparatuses are described herein. Some methods may include receiving video content, receiving metadata including a hierarchical order of metadata fields, and performing an enhancement operation on at least a portion of the video content according to settings associated with at least one of the metadata fields. The enhancement operation may include a video processing operation configured to modify one or more visual characteristics of the video content. The settings associated with the metadata field(s) may be predefined in a device that receives the video content and the metadata. The enhancement operation may be performed at a time based on a time code in the video content. The enhancement operation may be performed on a bounded area of an object. The hierarchical order may correspond to a type of display technology. The hierarchical order may correspond to information associated with a manufacturer of a display.
