SUBSTANCE: proposed local network 10 has subscriber leads 21 coupled with cabletelecasting head station 11 in desired carrier band. Network 10 also has noise suppression unit 21 whose input 24 is connected to leads 21 and output, to station 11. Unit 23 has band filters 28 - 31 connected to input 24 and using different passbands and transducers 32 - 35 designed for comparing output signal level of respective filter 28 - 31 with preset reference level and for feeding comparison result dependent logic signals to logic control unit 36 that functions to find out if these signals comply with conditions stored in unit 36 so as to convey control signal to unitized interlocking circuit 26 inserted in separate line 25 used to transfer signals from input 24 to output 27. Circuit 26 passes signals when logic signals received by unit 36 meet conditions stored therein.

EFFECT: provision for integrating interlocking means of noise-suppression unit in unitized interlocking circuit common for all carrier passbands.

FIELD: engineering of receivers-decoders used in broadcasting systems such as television broadcasting system, radio broadcasting system, cell phone communication system or other similar systems.

SUBSTANCE: method includes performing transmission to receiver-decoders through broadcasting system of a command, ordering receiver-decoders to perform an action; when command is receiver, identifier of command stored in current command is compared to identifiers of commands stored in memory of current decoder-receiver; aforementioned action is only executed in case when command identifier is not stored in memory.

EFFECT: transmitted commands are only executed once and information related to each receiver-decoder malfunction and may be useful for detecting and repairing malfunction is extracted remotely.

FIELD: technology for providing centralized remote control over digital television systems.

SUBSTANCE: interface of global WAN network is emulated for IP datagram over original remote interface of adapter and simple IP datagram transfer function is added between global WAN network interface and original Ethernet network interface in accordance to protocols stack. Therefore, system for controlling local network of digital television system performs IP connection to systems for controlling local area networks LANs of other digital television systems, then datagram is transformed to transport packets and transferred jointly with other transport packets via one and the same channel.

EFFECT: possible exchange of control data via network without mounting an additional commutation network.

FIELD: computer science, technology for dynamic control over volume of video data, sent to terminal from server, on basis of data transfer speed in the network.

SUBSTANCE: in the method for providing video data stream transfer service, server determines, whether filling is less than threshold value, or not less, than second threshold value of service, while filling represents amount of data, filling queue generation buffer in a terminal, while first threshold value is less than second threshold value. If the filling is less than first threshold value, than server provides data stream transfer service at predetermined bit transfer speed of service, which is less than current bit transfer speed of service. If the filling is equal to or greater than second threshold value, then server provides service of data stream transfer at predetermined service data transfer speed, which is greater than current bit transfer speed of service.

EFFECT: prevented sudden interruption or delay of data reproduction in the terminal.
