Modern aircraft information and telecommunication systems are segmented into two separate networks: data transmission and video networks. This differs from the typical approach for modern telecommunications in which all types of traffic are transmitted through one network (for example, access NGN-IMS networks). The external aircraft electromagnetic environment is constantly becoming more complicated: the high intensity of the electromagnetic field (Emf) due to the increase of radio frequencies quantity and their frequencies spectrum expansion, which occupies a band from 10 kHz to 3 GHz that affects the quality of service of electronic devices on board. A new method of image representation with forward error correction (FEC) codes was developed and considered. The method decreases the Bit Error Ratio (BER) for asymmetric data transmission via fiber optics and computational complexity for video correction. The paper investigates the superior performance of Low-Density Parity-Check (LDPC-) based on Irregular Repeat-Accumulate (IRA) codes over regular LDPC codes for the same code rate with Gaussian noise to match a certain signal-to-noise ratio (SNR). The LDPC FEC codes are simulated with code rates Rc ∈ {1/2} from the digital video broadcasting by satellite – second-generation (DVB-S2) standard. This setup has 17 low-data network subscribers and one highly loaded network section for video transmission. This approach makes it possible to increase the load in the asymmetric networks for aircraft onboard electronic systems and to ensure the quality of video images in the pickup environment to avionics during operation, for example, radar devices
