Line 6:
EPGs are typically sent within the broadcast [[transport stream]] (included in [[teletext]], like [[MHP]]), or alongside it in a special [[data]] channel. The [[ATSC]] standard for DTV uses tables sent in each station's [[PSIP]], for example. Users of some systems, notably [[TiVo]], use a dial-up [[modem]] to retrieve EPG listings from a third-party [[server]], if there are only analog TV signals available. In the U.S., these devices receive [[time signal]]s from local [[Public Broadcasting Service|PBS]] [[TV network]] [[affiliate]], so that they can record on time.
