High Frame Rate Video Transport via HD Architecture Metadata Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video architectures are inadequate for supporting the bandwidth and timing requirements of high frame rate image sensors, leading to inefficient data transport and loss of data, as they are not designed to handle the large number of pixels generated by these sensors, and replacing existing infrastructure is impractical and costly.
Innovation Solution
A method and apparatus that mosaic high frame rate data into lossless segments, using pixel packing and metadata to reconstruct the raw data, allowing transport over existing HD video architectures by encoding information in VANC/HANC metadata and using multiple parallel connections, enabling legacy hardware to handle high frame rate video data.

Engineering Contradiction Analysis
1Ease of manufacture
If conventional HD video architectures are used to transport high frame rate video data, then existing infrastructure can be utilized, but bandwidth and timing requirements cannot be met
Solution Approach 1:
The patent divides the high frame rate video data stream into multiple lower-rate substreams that can be transported over existing HD video infrastructure. By segmenting the data into manageable chunks that fit within standard video protocol bandwidth limits, the system enables transport of high frame rate data (e.g., 1000+ fps) over conventional architectures designed for lower frame rates.
Solution Approach 2:
The patent introduces temporal dimension by using frame interleaving and packing techniques. Multiple frames from different time points are combined and transported in a single data stream, allowing the system to exceed the bandwidth capacity of individual video channels while maintaining compatibility with existing HD video infrastructure.
2Quantity of substance
If video compression techniques are used to transport high frame rate data, then bandwidth requirements are reduced, but data loss occurs
Solution Approach 1:
The patent creates multiple copies of video data across parallel transport channels using techniques like frame packing and interleaving. By distributing redundant data representations across multiple standard video streams, the system ensures that even if some data is lost or corrupted during transmission, the original high frame rate data can be reconstructed at the receiving end.
3Quantity of substance
If new video architectures are developed to support high frame rate sensors, then bandwidth and timing requirements are met, but cost and complexity increase
Solution Approach 1:
The patent makes existing HD video infrastructure multi-functional by implementing software-based processing that enables standard video architectures to handle high frame rate data. The system uses universal frame packing, interleaving, and unpacking algorithms that work across different video protocols and formats, allowing a single infrastructure to serve both traditional and high frame rate applications.
4Speed
If high frame rate video data is transported in real-time, then timing requirements are met, but bandwidth limitations cause data loss
Solution Approach 1:
The patent segments high frame rate video data into multiple parallel lower-rate streams that can be transmitted simultaneously over existing video infrastructure. By dividing the data stream and using techniques like frame packing and interleaving, the system achieves real-time transport of high frame rate data without overwhelming the bandwidth capacity of individual video channels.

AI summary
A system for transporting fast frame rate video data from a high frame rate image sensor mosaics and spreads the fast frame rate video data in 1920×1080p30 video frames for transporting via an existing standard video architecture. Packing information, spreading information, and unique ID/timestamps for each frame is encoded in metadata and inserted in ancillary metadata space of the 1080p30 video frames. A robust encoding scheme generates the metadata and ensures that the transported video can be reassembled into its original fast frame rate form after being spread over multiple channels.
