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 has standardized a number of return channels that work together with DVB(-S/T/C) to create bi-directional communication. RCS is short for Return Channel Satellite, and specifies return channels in C, K u and K a frequency bands with return bandwidth of up to 2 Mbit/s. DVB-RCT is short for Return Channel Terrestrial, specified by ETSI EN 301958.
DVB-T is a COFDM transmission technique which includes the use of a Guard Interval. It allows the receiver to cope with strong multipath situations. Within a geographical area, DVB-T also allows single-frequency network (SFN) operation, where two or more
The Pan-American television frequencies are different for terrestrial and cable television systems.

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.
These channels are called "physical channel(物理チャンネル)". For other countries, US channel table or European channel table are used. For channel tables with 6 MHz width, ISDB-T single channel bandwidths 5.572 MHz has number of carriers 5,617 with interval of 0.99206 kHz.
