Converter box channels list
In conventional analog television there clearly was a 1-to-1 correspondence amongst the channel number that the section marketed and the RF station frequency it occupied. Like, an analog station advertising itself as "Channel 11" occupied the frequency assigned to channel 11 by the FCC. The frequency occupied by channel 11 covers 198 to 204 MHz and it is centered in the mid-point between those frequencies (at 201 MHz). This implied that in the event that you knew the channel wide range of a TV place you might force your analog TV compared to that place regularity by going into the station number, no checking essential, as well as the television would go directly to the correct regularity.
In DTV, however, programs broadcast information such as for instance their call letters and their particular "virtual" channel number constantly as history data, therefore the RF station they use could be distinctive from the virtual station number. A channel might market itself as "DTV 68" or "68-1" but really utilize RF channel 42. Your DTV converter field (or digital TV) can not know this without scanning all for the channel frequencies to get it. When doing a scan, your DTV tuner is checking each of the feasible RF channel frequencies for a sign, assuming you're found, memorizing the marketed channel number.
The bonus to this usually programs can still advertise on their own given that exact same "virtual" station quantity because their past analog channel quantity, yet in reality transmit their particular RF signal on a TV channel number which can be unlike the "virtual" number.
Following the change some DTV programs begun to transmit their particular electronic indicators on the same RF television channel as his or her advertised virtual station number (DTV virtual station 11-1, within the instance above, moved to the RF TV channel 11 on Summer 12, 2009, changing its initial analog transmission on station 11 with an electronic transmission on station 11). Others failed to (DTV digital station 68-1 transmits on RF TV station 42).
a drawback to digital channels is that you must be able to receive all of the channels in your town within one scan. If for example the antenna has got to be oriented in one single place or path to receive some channels and in another way to get other individuals, it may be extremely difficult to pick up and memorize most of the networks in a single scan. If that's the case you have to count on the ability of one's converter package or DTV set to either perform a "channel add" scan or by hand tune to your RF station of a station (not all have this capacity). For the latter, discover the RF station number of the section out of this dining table underneath the line "Channel Numbers/Digital" enter this number to the RF channel box within the "manual station add" or "manual tuning" function of your converter box, after that adjust your antenna until the sign are received and put into the memorized channel listing.
