Embedding Intelligent Data in SDI Video Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intelligent transportation systems face high implementation costs and security concerns due to the need for laying IP networks to transmit intelligent information.
Innovation Solution
Intelligent information is transmitted by embedding it into video data using Serial Digital Interface (SDI), allowing existing coaxial lines to be used, thereby reducing costs and enhancing security through the closed nature of the SDI protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP network is used to transmit intelligent information, then transmission flexibility is improved, but implementation cost increases and security deteriorates
Solution Approach 1:
The patent merges intelligent information transmission with video data transmission by embedding intelligent information into video data frames. This combination allows both types of data to be transmitted through the same SDI interface, eliminating the need for separate IP network infrastructure and reducing implementation costs while maintaining transmission flexibility.
Solution Approach 2:
The SDI interface is made multi-functional by enabling it to carry both video data and intelligent information simultaneously. The video data frames are designed to accommodate embedded intelligent information, allowing a single interface to perform multiple transmission functions and reducing overall system complexity.
2Adaptability or versatility
If IP network is used to transmit intelligent information, then transmission flexibility is improved, but security deteriorates
Solution Approach 1:
By combining intelligent information with video data in the same transmission stream, the patent leverages the inherently more secure SDI protocol. The merged data structure maintains transmission flexibility while benefiting from the closed, secure nature of SDI, avoiding the security vulnerabilities associated with IP networks.
3Reliability
If separate transmission channels are used for video data and intelligent information, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges separate transmission channels into a single SDI interface by embedding intelligent information within video data frames. This consolidation reduces device complexity and infrastructure requirements while maintaining transmission reliability through the robust SDI protocol and structured data embedding approach.

AI summary
Embodiments of the present disclosures provide a method, system and apparatus for transmitting intelligent information. When one frame of video data x is to be transmitted, a SDI sending terminal determines whether there is intelligent information satisfying a transmission condition; the transmission condition comprising that intelligent information is not transmitted and transmission of a frame of video data corresponding to the intelligent information is finished. If there is the intelligent information satisfying the transmission condition, the SDI sending terminal adds intelligent information y being one item of the intelligent information satisfying the transmission condition into a preset position of the video data x; and transmits the video data x having the intelligent information y. By using the solutions of the present disclosures, implementation costs are reduced and security is improved.
