SYSTEM FOR GENERATING AND TRANSMITTING TRANSPORT STREAM OF VIRTUAL CHANNEL SERVICE Russian patent published in 2024 - IPC H04N21/458 H04N21/2347 H04N21/266 H04H60/72 

FIELD: electric communication technique.

SUBSTANCE: invention relates to the field of satellite broadcasting and can find application in its organization and creation of dedicated "virtual" television channels (VC). Disclosed is a system and a method for generating and transmitting a transport stream of a VC providing service, comprising a transmitting side of a satellite broadcasting system with a multiplexer, an electronic program guide (EPG) server and a conditional access subsystem (CAS), equipped with means of generating a transport stream of linear channels (LC), wherein the EPG server is equipped with means of generating metadata of the VC service and the VC event schedule, with setting for each event of sampling the identifier of the corresponding VC and marking the use of the event in its composition; and CAS subsystem is equipped with means of generating control words with their session keys encryption, as well as ECM and EMM messages containing them, for each LC and VC service or their group, with setting access rights to broadcast of the specified in the schedule event of the linear channel as part of VC and its suspension at the end of the event.

EFFECT: high reliability of generating a transport stream of a virtual channel service providing broader capabilities of broadcasting content without increasing transponder capacity and memory capacity of the transmitting side while maintaining or improving the level of content protection.
