Provided are a DVB terminal, system and EPG data uploading method, the method comprising: acquiring electronic program guide (EPG) data of one or more services; according to pre-received event information table (EIT) information and network information table (NIT) information, determining whether an EPG server has corresponding EPG data; and if not, then uploading the EPG data to an EPG server. By employing the technical solution of the present invention, a DVB terminal can upload the EPG data to the EPG server, and the EPG server acquires real-time EPG data via each DVB terminal, and transmits the real-time EPG data to the DVB terminal requesting the EPG data, thus improving the real-time availability and accuracy of EPG data acquisition.
