Analog and Digital Tuning

One of the biggest paradigm shifts in digital TV is how channels are accessed. Gone is the familiar Channel

33. Now you have 33-0, 33-1, 33-2, and so on. In a nutshell, the new tuning options are:

Analog Channels. Entering the number-0 accesses the traditional analog TV channel.

Digital Channels. Entering the same channel-1 tunes the digital equivalent of the analog channel.

Note that the digital channel is broadcast on a UHF frequency. Digital tuners see the channel ID (NN-

1) in the signal and lists by that name instead of the actual frequency. This way, the broadcasters

keep their channel identity, even when analog goes away.

Multicast Digital Channels. Because digital is more compressed than analog, broadcasters are

often including additional sub-channels, listed as NN-2, NN-3; up to 6 if the station is only

broadcasting SD quality programming.

Two-Digit Tuning. If you are currently watching a digital channel, entering the old channel format,

such as 33, will access 33-1. If you are watching an analog channel, entering 33 will take you to 33-

0.
