FIELD: physics, computer engineering.SUBSTANCE: invention relates to systems of multimedia flow transmission, particularly, to systems and methods adapted to conditions of network and buffers. Proposed system of flow transmission with request of blocks comprises perfection of user perception and efficiency of application of frequency band of such systems, normally, using the usage system. The latter generates data in the form that should be serviced by common file-server (HTTP, FTP or the like). Note here that said usage system consumes the content to shape it to files or data elements to be serviced by file-server. This system includes the control over sequence, clocking and structuring of blocks requests. This is based on time of indexing, varying the blocks sizes, optimum separation to blocks and control over location of arbitrary access points. The latter comprises versions of multiple representation, dynamic updating of data representation and/or efficient presentation of content in real time and time shift.EFFECT: optimised representation transmitted as multimedia flow, efficient simultaneous or time distributed delivery of multimedia data flow.8 cl, 32 dwg |
