The software and hardware complex forms an electronic hydra (EPG)

Electronic program guide (EPG, electronic program guide) is an on - screen menu that displays a list of digital TV and radio programs. At the head stations of cable television, the EPG formation occurs by inserting the SI (Service information, service information) in the DVB MPEG-2 TS transport streams, which further allows the subscriber set-top boxes to identify a list of programs and other data broadcasting from the transport stream. EPG broadcasting from the head station is performed at once to all subscribers and gives them a possibility of convenient choice of TV programs for viewing. To form an EPG, you need to edit the TDT, TOT, and EIT tables.
