Señal Colombia —Colombia's state-owned channel— has made digital terrestrial television broadcast tests since 2006, in northwest Bogotá and downtown Cartagena, transmitting into the three DTV formats ATSC, DVB-T and ISDB-T.
Other standards, such as digital multimedia broadcasting (DMB) and digital video broadcasting - handheld (DVB-H), have been devised to allow handheld devices such as mobile phones to receive TV signals. Another way is Internet Protocol television (IPTV), which is the delivery of TV over a computer network.

This is in addition to other standards like the now-defunct MediaFLO, and worldwide open standards such as DVB-H and T-DMB.
