Background. Decoding information using noise-tolerant Reed–Solomon codes is a very resource-intensive task in part of calculation imlpementation. This problem is especially relevant when video streams or telemetry decoding on the fly, in a time mode close to real time. Matherials and methods. The article discusses two methods of optimal organization of Reed – Solomon decoding. First method is a decoding into several computational streams, some processor threads using. Second method is an artificially reducing the number of errors corrected by the Reed–Solomon code to reduce calculation time. Results. The experimental verification of these methods is considered. Recommendations for their application, both separate and joint, are given. Conclusions. Methods can be used in video streaming processing systems. Processing system must allow use either both method or one selected by operator.
