Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In monitoring systems, transmitting data other than image and coaxial data requires additional wiring, increasing device costs and complexity.
Innovation Solution
A data transmission method where target data is sent within the effective image area of an image frame using the same transmission channel as image data, eliminating the need for additional wiring by alternating first and second image frames, with target data carried in the effective area of the first frame and image data in the second frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional wiring is arranged to transmit target data between devices, then the transmission capability is improved, but the device cost increases
Solution Approach 1:
The existing transmission channel originally designed for image data is made multi-functional by enabling it to transmit both image data and target data. The camera alternates between sending image frames and target data frames through the same channel, eliminating the need for additional wiring while expanding transmission capability.
Solution Approach 2:
The patent merges the transmission of image data and target data into a single transmission channel. By combining these two separate data streams and transmitting them alternately through one channel, the system avoids the cost of additional wiring while maintaining full transmission functionality.
2Adaptability or versatility
If additional wiring is arranged to transmit target data between devices, then the data transmission functionality is improved, but the device complexity increases
Solution Approach 1:
The single transmission channel is designed to perform multiple functions: transmitting image data during first image frames and target data during second image frames. This multi-functionality eliminates the need for separate wiring for different data types, reducing overall system complexity.
Solution Approach 2:
The camera employs periodic action by alternating between transmitting image data and target data in a regular sequence. This periodic transmission pattern allows the single channel to handle multiple data types systematically, avoiding the complexity of simultaneous multi-channel transmission.
3Ease of manufacture
If the same transmission channel is used for both image data and target data, then the device cost is reduced, but the data transmission efficiency may be affected
Solution Approach 1:
The system maintains data transmission efficiency through periodic action by alternating transmission between image data and target data at high speed. This rapid alternation creates the effect of simultaneous transmission, preserving efficiency while using a single channel to reduce costs.
Solution Approach 2:
The transmission channel operates continuously without idle time, alternating between transmitting image data and target data. This continuous operation ensures that the channel is fully utilized, maintaining high transmission efficiency while avoiding the cost of additional wiring.

AI summary
Embodiments of the present application provide a data transmission method, a camera and an electronic device. The method includes: acquiring to-be-sent target data; and sending the target data, as data carried in an effective image area of a first image frame, by using a data sending manner for the effective image area, through a same transmission channel as used in transmitting image data; wherein, the target data is different from the image data and coaxial data, the coaxial data is notification information for an interaction between a data receiving end and a data sending end, and the first image frame has a different type from a second image frame carrying the image data without carrying the target data. Applying the solutions provided by the embodiments of the present application, the transmission of the target data can be realized without additional wiring, thereby reducing the device cost.
