The term "multicasting" means a cool new way for your local TV broadcasters to give you additional programming! We all know as we were growing up you had your 3 main networks such as NBC, CBS and ABC. In my neighborhood in St. Louis, the channel numbers were 5, 4 and 2... respectively. Channel 5 has an extra channel now and channel 2 has a cool new channel that delivers nothing but old '60, '70 sitcoms! One of our local stations has 3 extra broadcast material and yet another offers an extra channel of content to watch. These stations are easy to choose among because they simply add a ".1, .2 or .3 behind the main channel number. For instance:
5.1, 5.2, 2.1, 2.2, 9.1, 9.2 and finally 9.3
Still to this day, many homeowners are unaware of the extra local TV stations they can get simply by owing a TV antenna. The antenna can be installed on the roof or in some instances (if your close enough to your stations digital tower) inside your attic. If your lucky to live 5-15 miles away from the towers and your terrain is fairly ideal (flat and no tall building near you).. an indoor antenna may work fine! Just another advantage we the TV viewer received when the digital transition went into effect.
