TV Channels in Northern Michigan
By June 12, 2009 all full-power broadcast television stations in the United States will stop broadcasting in analog NTSC and begin broadcasting only in digital DTV - HDTV. Digital broadcasting will allow stations to offer improved picture and sound quality and additional channels.
While the majority of the viewed TV broadcast stations are full-power stations, three other categories of TV stations exist - low-power, Class A, and translator repeater stations. There is currently no deadline for these stations to convert to digital broadcasting.
Consumers will benefit because digital broadcasting allows stations to offer improved picture and sound quality,
and digital is much more efficient than analog. For example, rather than being limited to providing one analog program,
a broadcaster is able to offer a super sharp, "high definition," (HD) digital program or multiple, "standard definition,"
(SD) digital programs simultaneously through a process called, "multicasting.,"
Multicasting allows broadcast stations to offer several channels of digital programming at the same time, using the
same amount of spectrum required for one analog program. So, for example, while a station broadcasting in analog on
channel 7 is only able to offer viewers one program, a station broadcasting in digital on channel 7 can offer viewers
one digital program on channel 7-1, a second digital program on channel 7-2, a third digital program on
channel 7-3, and so on. This means more programming choices for viewers.
