EPGs are typically sent within the broadcast [[transport stream]] or alongside it in a special [[data]] channel. The [[ATSC]] standard for DTV uses tables sent in each station's [[PSIP]], for example. These tables are meant to contain the program start time and title, and additional program descriptive "metadata". In the U.S., these devices receive [[time signal]]s from local [[Public Broadcasting Service|PBS]] members, so that they can record on time. Most systems, however, rely upon third party "metadata aggregators" (companies such as Tribune TV Data or Gemstar TV Guide in the U.S. and Europe), to provide good quality data content.

An exapmleexample of an EPG system is [[Guide Plus]]+.
