An important benefit of the switch to all-digital broadcasting is that it will free up parts of the valuable broadcast spectrum for public safety communications (such as police, fire departments, and rescue squads). Also, some of the spectrum will be auctioned to companies that will be able to provide consumers with more advanced wireless services (such as wireless broadband).
Consumers also 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. Further, DTV can provide interactive video and data services that are not possible with analog technology.
I personaly believe that they do that to earn more money, I mean, i have no problem with them switching, but hey what do i know
how did the mandate of heaven affect government in china
A representative form of government derives its mandate to govern from the consent of the people to be governed. The governed peopel can withdraw, recall, or change their mandate by means of regularly scheduled elections but if/when the government refuses to obey the mandate of the elctorate it is possible that revolution or civil war could occur when the people attempt to remove the no-longer-legitimate government by force.
the chinesebelief the mandate of heaven have worked for and against stability in the government because they can
Ancient China's Government was a Monarchy.
When a higher level of the U.S. government (i.e. the federal government) tells lower branches of the government (i.e. state governments) to do something, that's a mandate. If the federal government give the states money to help them do whatever they want them to do, that's a funded mandate. If they don't, if they just expect the states to do it on their own, that's an unfunded mandate. So when the Americans with Disabilities Act was passed, the federal government told the state governments they had to make all their office buildings handicap-accessible. They did give the states some money for the construction (although some say not enough), so that was a funded mandate.
A federal mandate
When a federal law requires a lower government to meet a particular obligation, this is referred to as a federal mandate. The Americans with Disabilities Act is an example of a federal mandate.
It gave legitimacy to the form of government being established
Yes. My government should mandate the use of materials that biodegrade once their useful life is over. Whether anyone will note, remember, or heed what the government mandates is another issue entirely.
Kinda, but not really. The federal government does not have the power to mandate states to adopt setbelt laws. However the federal government does seem to have the power to threaten cutting off federal transportation money to states which refuse to.
with a mandate the federal government tells a state government what it must do if it wants grant money.
"The British Mandate of Palestine (1917-1922) afforded the Empire governance authority over what is today Israel and Jordan." In this example the mandate is equated with the enforcing an act. Another example is the United States' Affordable Healthcare Act Mandate that individuals purchase insurance, or apply to Medicaid (in applicable States). Here mandate is a government creating an enforceable requirement.
