Abstract:
The problem of improving the communication channel capacity of the small spacecraft was considered. The multidimensional spatial encoding method aims to provide efficient video transmission in the low-speed service channels. The method is based on a hybrid encoding approach and the standard H.265. The goal of this paper is to show the development results of the compression model and algorithms. The results have been obtained in the Matlab / Simulink environment. Final video-coding results showed the practical efficiency of the methods and algorithms. The development ways of the method and video compression system have been formulated. The main purpose of the subsequent works is the practical realization of single-chip encoder system based on H.265 standard and multi-dimensional spatial transformation.
