FIELD: communication technique.
SUBSTANCE: invention relates to satellite broadcasting. System processing of transport stream and virtual channels service receiving part metadata contains interfaced with cryptomodule and main processor CPU implemented by software and hardware method: means of detecting and descrambling in the ECM messages of the transport stream copies of the descrambling keys CW of each included in the virtual transmission channel of the linear broadcast channel, encrypted by the session key of the virtual channel during the broadcast of the transmission of the linear channel in the virtual service channel, and the main processor CPU is equipped with software and hardware for detecting in the transport stream of metadata of the virtual channel service decrypted by means of a cryptomodule and adding virtual service channels in the user interface of the receiving part based on their parameters in the list of linear channels, creating a schedule of virtual channels and displaying it in the corresponding module of the user interface, processing of virtual channel rights and keys setting from transport stream and virtual channel content reproduction based on them by means of automatic switching to linear broadcasting channel, broadcasting content of current event in accordance with generated schedule of virtual channel.
EFFECT: broader operational capabilities of the broadcasting system owing to broader capabilities of broadcasting content without increasing client-side memory, transponder capacity, and with simultaneous increase in content protection level.
