METHOD AND DEVICE FOR HIGHLY EFFICIENT COMPRESSION OF LARGE-VOLUME MULTIMEDIA INFORMATION BASED ON THE CRITERIA OF ITS VALUE FOR STORING IN DATA STORAGE SYSTEMS

摘要

FIELD: data processing.;SUBSTANCE: invention relates to means for compressing, transmitting and storing multimedia information in a compact form. Method for compressing large-volume multimedia information (MI) in digital form for transmission over communication channels or storage in data storage systems, in which video, voice and audio streams are coded taking into account their specificity, respectively, by video, voice and audio codecs, compressed into a common multimedia stream transmitted over telecommunications channels or placed as separate files or in a common file into storage devices, and are restored at the output of the channel or when retrieved from the memory device in a form acceptable to the consumer or the decision-maker separately for each stream or after decompression of the common stream and decoding of the compressed video, the voice and audio information are combined into a common recovered media stream, the overall stream and its individual components are divided into an informationally significant part and an informational insignificant part according to the information value criteria, while the information-insignificant part is significantly reduced in volume.;EFFECT: technical result consists in increasing the speed during compression of multimedia information.;15 cl, 6 dwg
