The following results were obtained: high-speed signal compression algorithms, crypto-resistant and noise-resistant data coding; algorithms for the formation the minimum duration of cryptoresistant and noise-resistant code-signal sequences of information packets with an increased information capacity; one-norm integer cosine transforms of order 8, 16 and their fast algorithms of low computational complexity; matrix method for constructing a one -norm simple integer cosine step transform of order 32 with a fast algorithm of low complexity; algorithms for determining the integral indicators of video data; modification of the sigma filter; algorithms for reducing the bit depth of amplitude values.
