Will the move to HD in TV programming take up more cable bandwidth than the current analog programming?

I.e. , when the HD change is over and done, and assuming my cable provider does not add cable capacity, will my TV cable be able to carry more channels than it does now (excluding the current duplication where there are both HD and analog versions of the same channel)?

No. It's exactly the opposite. HD programming consumes much more bandwidth than SD digital or analog cable (cable guy told me 4x the bandwidth).

I think you will always have more channels, but only because cable TV companies will continue to upgrade their bandwidth capabilities in order to remain competitive with more HD and digital "on demand" channels.

Digital compresions helps, however it will depend in your cable company From the Wikipedia, we can read at the main article:"However, the standardization of HDTV did not lead to its adoption. Early HDTV commercial experiments such as NHK's MUSE required over four times the bandwidth of a standard definition broadcast, and despite the effort made to shrink the required bandwidth into about 2 times of that of the SDTV's, it still was distributable only by satellite. In addition, recording and reproducing an HDTV signal was also a technical challenge in the early years of HDTV.

Nevertheless, the first HDTV sets went on sale in the United States in 1998. Japan is the only country with successful commercial analog HDTV, known as " featuring a 5:3 aspect ratio screen with 1,125 interlaced lines (1,035 active lines) at the rate of 60 fields per second. Elsewhere, in Europe, analog 1,125-line HD-MAC television failed in its test broadcasts in the early 1990s.

However, it was not until the early 2000's that storage means of enough capacity and computer processing power for dense compression algorithms made commercial applications of HDTV affordable for consumers and profitable for TV channels or the video rental industry. "This means that the actual digital compresion algorithms help a lot in reducing the amount of bandwidth that the HDTV takesHowever, if we keep reading we can find this:"Broadcasters may aggressively compress video to save bandwidth and therefore broadcast more channels - this compression manifests itself as reduced video quality. "later:"As of 2007, broadcasters may demand, or cable-television operators may elect, to place HD signals in a premium band that requires higher cable fees.

That some satellite companies offer the local HD channels as a service at additional cost (transmission comes from satellite) suggests to some broadcasters that on-air broadcasts of local HD signals must be a premium service to subscribers. Viewers may be denied some television channels that they expected, be allowed only access to the non-digital, and obviously sub-standard non-digital signal, or have to install an antenna to receive the digital broadcasts. Such issues more entail economic and legal disputes than they entail technology."This means that much of what will happen will depend on the decisions made for the "broadcasters" meaning the cable companys.

I don't know what your cable company will do, but your toughts may be real. Sources: http://en.wikipedia.org/wiki/gh-definition_television .

1 CABLE COMPANYS ARE REBUILDING THEIR TRANSMISSION LINES - Fiber -optics are replacing copper coaxial on long runs (TO THE HEAD END) Signal compression is also used , these two technologies working in tandem;allow for more information to be transmitted on smaller more efficient conductors , the result -many more channels in HD .

2 I meant "from the head end" or the beginning of a cable system and the fiber -optics are used for trunk-lines (long runs) from the source ,digitalizing(mpeg conversion) the signal allows for more channels on a single slice of bandwidth of which there are many right now 550mhz or the possibility of 1000 channels all in HIGH DEFINITION, HAPPY TV WATCHING! .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
