FIELD: physics; communication.
SUBSTANCE: invention relates to digital video broadcasting systems using an electronic service guide (ESG). A device is proposed for handling errors in ESG transmission in a digital video broadcasting system, which includes a service application (SA) component for receiving a request message for file restoration from a communication terminal after transmitting ESG from a service management (SM) component to a terminal and, if the request message for file restoration is an ESG request, providing the SM component with a request message for file restoration and a terminal address; a logic device for compiling ESG for generating ESG within a SM component which interprets the request message and determines whether to resend the ESG to the terminal, and if a decision is made to resend the ESG, the logic device for compiling the ESG sends ESG metadata and terminal address to an interactive server for transmitting ESG within the SM component, and the interactive server sends ESG metadata to the terminal.
EFFECT: design of a video broadcasting system capable of sending a restoration request to a network and receiving a repeatedly transmitted ESG when an error occurs during transmission of the ESG.
