2.INTRODUCTION: THE BASICS

About Digital Channels

Currently, all broadcasters have an analog TV channel and a digital TV channel. The digital bandwidth has the capability of accommodating more than one program stream because each broadcaster’s assigned digital channel carries a 19.39-megabit-per-second (Mbps) digital data stream. This allows the broadcaster the option of broadcasting a single program or dividing the digital data stream into multiple programming streams. These streams include the “major” channel specific to a broadcasting station, as well as any additional programming streams on the bandwidth, which are referred to as “minor channels” or “sub-channels,” each broadcasting a different program. As a result, the numbering system for digital channels is different than that of traditional analog TV.

Digital Virtual Channel Number Physical Channel Number

Here’s how it works:

ξThe number in parentheses to the right is the actual physical channel number of the transmitter used to broadcast the network programming in your region

ξEach physical channel is mapped to one or more digital channel numbers, known as “virtual channels,” and represented by a number, followed by a dot and then another number; for example, 7.1, 7.2, etc. (the old analog channel is always referenced to minor channel “0”, as in 7.0, while 7.1 would represent the new digital television channel)

—The first number is the major channel used for all channels of a particular broadcasting station

—The number following the dot is the minor channel number assigned to each broadcaster’s additional programming streams; digital television stations may have only one virtual channel, or as many as six

There are several ways to input digital television channels:

User Input (double-digit channels)	Channel Displayed
11 . 3	Channel 11 . 3
113	Channel 11 . 3
User input (single-digit channels)
052	Channel 5 . 2
5.2 + Ent	Channel 5 . 2
