FIELD: physics, computer facilities.
SUBSTANCE: invention concerns the data transmission interface, and is concrete to interface USB (universal serial bus) for communication and data transmission between a host processing device of numeral signals (for example, the receiver of digital TV (DTV)) and the exterior block of service (for example, the block of the conventional access (CA) for DTV). Universal interface of transmission (UIT) contains an r-t unit for reception and data transmission which specifications USB correspond, the block of detection for detection of the data accepted by the send-receive block to spot, whether it is necessary to converse the accepted data in data which correspond to any concrete specification. And also the transformation block, for transformation of the accepted data to the data corresponding to the concrete specification after necessity of such transformation, and for transformation of the transmitted data corresponding to the concrete specification, in data which specifications USB correspond is spotted, for transmission through the mentioned send-receive block. As the invention offers EBG, service cards can be separated from DTV devices, and various services with the added cost can be rendered.
EFFECT: maintenance of two-forked data transmission by granting of DTV services in real time, is thus possible linking of remote terminal units of various types.
