Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems face interference issues due to shared frequency bands, leading to poor performance and high costs in maintaining stability, especially in complex wireless environments.
Innovation Solution
A data transmission system that splits video data into multiple frames and further divides each frame into data packets, transmitting these packets over different frequency bands using multiple transmitting and receiving units, allowing for data fusion and correction to ensure reliable transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If type I fixed frequency band transmission is used, then device complexity is reduced, but anti-interference performance deteriorates causing picture freeze, blur or mosaic
Solution Approach 1:
The patent divides the transmission system into multiple independent transmitting units, each operating on different frequency bands. Each unit transmits data packets independently, and the receiving unit combines them to reconstruct the complete video frame. This segmentation allows the system to maintain simplicity in each individual unit while achieving high reliability through diversity in the overall system.
2Reliability
If type II automatic frequency switching is used, then anti-interference performance improves, but transmission stability deteriorates due to temporary freeze or black screen during switching
Solution Approach 1:
The patent prepares multiple transmitting units operating on different frequency bands in advance, before interference occurs. When interference is detected on one frequency band, the system can immediately switch to another pre-configured frequency band without interruption, as the alternative transmitting units are already ready to transmit. This eliminates the freeze or black screen issues associated with real-time frequency switching.
3Reliability
If type III frequency hopping technology is used, then anti-interference performance improves, but device complexity and development cost increase
Solution Approach 1:
The patent merges multiple simple transmitting units into a single coordinated system. Each transmitting unit is simple and inexpensive, but when combined, they provide frequency diversity and improved anti-interference performance. The receiving unit combines the outputs of multiple receiving units to reconstruct the complete video frame, achieving high reliability without requiring complex frequency hopping algorithms or expensive hardware.
4Reliability
If multiple frequency bands are used simultaneously, then anti-interference performance improves, but device complexity increases
Solution Approach 1:
The patent segments the transmission function across multiple independent units, each handling a specific frequency band. This segmentation allows for simple, dedicated hardware in each unit while achieving complex overall functionality through parallel operation. The receiving unit similarly segments the reception process, combining data from multiple frequency bands to reconstruct the complete video frame.

AI summary
Disclosed is a data transmission system having a transmitter and a receiver. The transmitter encodes external input signals to acquire coded transmission data transmitted in multiple paths with different frequency band, and then transmits them to respective receiver; and the receiver performs data fusion on the received transmission signals to acquire coded received data, and decodes it to acquire and output the decoded data. In conclusion, since the received signals are split into a plurality of transmission signals of different frequency bands by the transmitter and the signals are fused in the receiver, the signals are not susceptible to the same frequency interference during transmission, improving the anti-interference of the data transmission system, realizing high-reliability transmission at low cost or in a complex wireless environment, also expanding the applications of the data transmission system.
