Imaging Metadata Transmission With Frame-Aligned Video Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for associating image sensor metadata with audiovisual data require separate transmission and subsequent frame-alignment, leading to inefficiencies and reduced reliability for real-time applications.
Innovation Solution
Transmitting metadata and audiovisual data in a frame-aligned manner by incorporating metadata into predefined data structures or channels, such as HDMI InfoFrames, ensuring synchronized delivery without additional processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If metadata and audiovisual data are transmitted separately, then transmission flexibility is improved, but frame alignment reliability deteriorates due to temporal calibration requirements
Solution Approach 1:
The patent combines metadata and audiovisual data into a single transmitted data structure, eliminating the need for separate transmission channels. This merging ensures that both data types arrive simultaneously at the receiving device, inherently achieving frame alignment without requiring separate temporal calibration processes.
Solution Approach 2:
The patent introduces a data structure as an intermediary container that holds both metadata and audiovisual data together. This intermediary structure serves as a unified transmission unit that maintains the relationship between metadata and video frames, ensuring reliable association without separate transmission.
2Use of energy by moving object
If metadata is transmitted on a separate channel from audiovisual data, then transmission channel utilization is improved, but processing efficiency deteriorates due to post-transmission frame alignment requirements
Solution Approach 1:
The patent merges metadata and audiovisual data into a single transmission unit, eliminating the need for separate transmission channels. This approach may reduce the number of active channels but ensures that both data types are processed together immediately upon receipt, significantly improving processing efficiency by eliminating post-transmission alignment operations.
3Adaptability or versatility
If separate transmission of metadata and audiovisual data is used, then transmission protocol flexibility is improved, but real-time processing capability deteriorates due to temporal calibration delays
Solution Approach 1:
The patent combines metadata and audiovisual data into a single transmitted data structure, ensuring they arrive simultaneously at the receiving device. This eliminates temporal calibration delays entirely, as there is no time difference between the arrival of metadata and audiovisual data, enabling immediate real-time processing.
Solution Approach 2:
The patent performs the association between metadata and audiovisual data during the transmission process itself, rather than after receipt. By embedding the relationship in the transmitted data structure, the system eliminates the need for subsequent temporal calibration operations, reducing processing time.
Data Source
AI summary
A system for transmission of imaging metadata includes a first sensor configured to capture video data. The system includes a data transmission device configured to receive the video data from the first sensor, receive metadata, transmit the video data via a first channel configured according to a predefined data transport protocol, and transmit the metadata via a second channel configured according to the predefined data transport protocol.
