Frequency spacing for each channel in Japan is the same as in the countries listed above, but the channel numbers are 1 lower than in those countries; for example, channel 13 in Japan is on the same frequency as channel 14 in North and South America (most countries), South Korea, Taiwan, and the Philippines.
Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation ...
Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television ...
The five main ATSC formats of DTV currently [when?] broadcast in the U.S. are: . Standard definition—480i, to maintain compatibility with existing NTSC sets when a digital television broadcast is converted back to an analog one [citation needed] —either by a converter box or a cable/satellite operator's proprietary equipment
The Pan-American television frequencies are different for terrestrial and cable television systems. Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 36 and occupies frequencies between 470 and 608 MHz.
The exception is Freeview Australia Ltd., which also use the NorDig method and partly follow the ATSC practice of using the same VHF radio-frequency channel allocation that the PAL channel is simulcasting on from the metropolitan station's main transmission point (ie. 2, 7, 9, and 10) with the major and minor format emulated by multiplying by ten.
Digital-television radio, DTV radio, or DTR describes the audio channels that are provided with a digital television service. [1] These channels are delivered by cable television, direct-broadcast satellite or digital terrestrial television. [2] In terms of variety, DTR falls somewhere between regular AM and FM radio, and satellite radio.
To implement the digitization plan, provinces and cities are divided into 4 groups on the basis of socio-economic development level, radio transmission conditions and local frequency allocation capability. [4] Each stage of television digitization will be done with each of these groups. [5]
