Solution Overview

Problem

In surveillance systems, transmitting data other than images and coaxial information requires additional wiring, increasing facility costs and inefficiencies in data transmission.

Innovation Solution

A method where the to-be-sent image and target data are positioned within the same image frame, allowing them to be sent through the same transmission medium without additional wiring, by determining specific positions for both within the effective image area and potentially using the blanking area for coaxial data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional wiring is used to transmit target data, then data transmission capability is improved, but facility costs increase

Engineering Contradiction:
Improvedata transmission capabilityVSAvoidfacility costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The existing transmission cable is made to serve multiple functions: transmitting image data, coaxial data, and target data simultaneously. The image frame structure is designed to accommodate multiple types of data in different areas (effective image area for image and target data, blanking area for coaxial data), allowing a single cable to replace multiple separate transmission paths and reducing facility costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple data streams (image data, target data, and coaxial data) are merged into a single transmission channel. The patent combines these different data types into one integrated image frame structure that can be transmitted through a single cable, eliminating the need for separate wiring for each data type.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of information

If additional wiring is used to transmit target data, then data transmission completeness is improved, but system complexity increases

Engineering Contradiction:
Improvedata transmission completenessVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The transmission system is designed to handle multiple data types through a unified interface. The image frame structure incorporates designated areas for different data types, allowing the system to maintain data transmission completeness while avoiding the complexity of multiple separate transmission paths and their associated wiring infrastructure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If coaxial cables or twisted pair cables are used for transmission, then transmission reliability is improved, but facility costs increase when additional wiring is added

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidfacility costs
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple data transmission functions into a single existing cable infrastructure. By designing the image frame to contain all necessary data (image, target data, and coaxial data) in a unified structure, the system maintains transmission reliability through the proven cable medium while avoiding the cost of adding parallel wiring for each data type.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Method for transmitting data, camera, and electronic device. The method includes: obtaining an to-be-sent image and to-be-sent target data; determining a first position for the to-be-sent image in an effective image area of an image frame, and determining a second position for the target data in an effective image area of an image frame; taking the to-be-sent image and the target data as data of the same image frame, and sending the to-be-sent image according to the first position and the target data according to the second position in a data sending mode for the effective image area. Target data is data other than to-be-sent image and coaxial data, and coaxial data is notification information exchanged between a data receiving end and a data sending end. In this way, target data and to-be-sent image can be sent to an electronic device through the same image frame without additional wiring. Facility costs are reduced.
