Will digital tv become anything like cable because it has extra bandwidth which can be used to broadcast more channels?

In reality, digital TV doesn't have extra bandwidth. It uses the same (or a little less) amount of bandwidth as standard NTSC television signal, but since it's digital in nature, they are able to multiplex up to eight TV signals within the same amount of transponder space. So yes, it can broadcast more channels.

What are the characteristics of switches?
- Data channels are shared among communication devices improving the use of bandwidth. - Messages can be stored temporarily at message switches, when network congestion becomes a problem. - Priorities may be used to manage network traffic. - Broadcast addressing uses bandwidth more efficiently because messages are delivered to multiple destinations.
Why is it a bad thing to have to large a broadcast domain?
Because it creates a lot traffic which takes a lot of bandwidth. As result you will have a slow network which spends most of its time on broadcasting.
Why are there naughty TV channels?
because certain people don't have anything better to do or to watch.
Why is it that before 911 they always showed the emergency broadcast system test and on 911 they never used it?
The Emergency Broadcast System (control of all broadcast channels) was never used because a national emergency was never declared. If there had been terrorist attacks all over the country, the EBS would have been used to broadcast instructions from the government to citizens in affected areas.
what is the alternative to televistion antennas?
Digital broadcast TV is an excellent alternative to television antennas because it allows the user to have cable picture quality viewing as well as addtional channels for no cost.
Is low bandwidth signal has more power than high bandwidth signal?
no,because generally the lower frequency side existed for lower bandwidth,and higher frequency side existed higher bandwidth,so thus we can say that lower bandwidth has generally has lower power as compared to higher bandwidth.
How much bandwidth does a standard TV channel use?
Standard OTA (Over the air) television channels are able to use about 19.3Mbps. If it's a channel that has several sub-channels for example 38.1 or 38.2 then they have to divide the 19.3Mbps up between the sub-channels. Generally speaking channels that are standard definition use anywhere from 4Mbps-7Mbps. High definition channels generally use anywhere from 10-15Mbps. When dealing with content that is on cable/Satellite though things change because different content providers compress each network different amounts.
Why is vhf considered the best way to call for help?
Because a VHF broadcast theoretically could reach thousands of people ! Additionally, if it's (for example) a marine or aircraft emergency, there are specific emergency channels, which are monitored 24/7 by professional people.

Why is The Simpsons broadcast to the U.K.?
Honestly... Why not. There really isn't a substantial answer anyone can give. It's broadcast overseas because it's simply is broadcast overseas. There was a market for it so it was.
What is advantage of lower bandwidth?
The reason for using lower bandwidth is that not all Internet users are able to download and use programs, videos, etc., with high bandwidth. In some cases the higher bandwidth files become corrupted or they stretch the resources of satellite and dial-up systems. Operating at a lower bandwidth provides an advantage because it solves such problems.
The relationship of the bandwidth required for double-sideband emitted carrier AM to the bandwidth of the modulating signal of?
In Amplitude Modulation (AM), specifically in the case of Double Sideband Suppressed Carrier (DSB-SC) or Full Carrier (DSB-FC) AM, the required bandwidth is twice the bandwidth of the modulating signal. If the modulating signal has a bandwidth of B Hz, the bandwidth required for AM would be 2B Hz. This is because both the upper and lower sidebands of the carrier wave are utilized in the modulation process, each consuming bandwidth equivalent to the original signal.
