On August 27, 2007, URSEC settled on DVB-T and DVB-H. The TV sets being sold in Uruguay seem to be closer to ATSC HDTV-based standards (60 Hz systems, with ATSC tuners in some cases). Most of the DVD-based content in the country is NTSC/60 Hz-based, while the TV standard in use is PAL/50 Hz-based.
ISDB-Tb frequency DTV channel 14 uses 473.142857 MHz, but ATSC 3.0, DVB-T/DVB-T2, and DTMB, use 473.0 MHz. Channel 37 is reserved for radio astronomy in the United States, Canada, Bermuda , Belize , and the Bahamas , thus there are no television stations assigned to it.
DVB-T, short for Digital Video Broadcasting – Terrestrial, is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television that was first published in 1997 [1] and first broadcast in Singapore in February 1998.

DVB-T, analogue systems B and G utilize the same 250 kHz guard-band. After analogue television transmissions have ceased, only the preferred main carrier wave centre frequency should be listed, because QAM modulates all AV channels and other data into a single H.222 data stream.
The vast majority of multiplexed channels use DVB-T 64-QAM modulation, for PAL , radio and interactive channels. HDTV channels use DVB-T2 256-QAM modulation and H.222 transports, while local channels [a] use DVB-T QPSK modulation.
DVB-T uses coded orthogonal frequency division multiplexing (COFDM), which uses as many as 8000 independent carriers, each transmitting data at a comparatively low rate. This system was designed to provide superior immunity from multipath interference , and has a choice of system variants which allow data rates from 4 MBit/s up to 24 MBit/s.
