Comparison For Broadband Internet Service and HDTV

Telephone, Internet, and live TV service are now routinely bundled by service providers. It is convenient to have a single provider and one bill a month. With the availability of VoIP (Voice over Internet Protocol), the lines between the different services have blurred further.

wideband Internet service (High Speed) for residential or small business requirements has usually been usable from two sources: DSL, a transcription that piggybacked on the telephone wiring from the telephone company, or conducting wire, a system that similarly piggybacked on the cable TV wiring. In 2010, near 25 million customers utilized cable broadband, and about 22 million customers utilized DSL. In 2001, a total of about 5 million customers used either cable broadband or DSL.

For most people the internet TV coaxial cable has allowed better performance than DSL, but if you were exceedingly price conscious, then the DSL cable may have been competitive. So, in a handling of broadband choices, we should include cable and DSL, but we will also discuss new options that are now available like WildBlue satellite, and services that will soon be available like WiMax (WiFi with a city-wide hot-spot) and ViaSat (satellite communications on steroids).

The Impact of Video Downloads (especially HDTV):

 ABI Research projects that the number of video downloads to increase from 215 million downloads this year (2008) to 2.4 billion downloads in 2012. This number becomes more impressive when one takes into account that a much higher per cent of those downloads in 2012 will be HDTV files, which are much larger (A non HDTV cinema is just about 3 GB/Hour, HDTV file size is drug-addicted on encoding: an MPEG-4 encoded HDTV movie file size is approximately 5 GB/Hour, an unencoded 1280 X 720 movie file size is over 150 GB/Hour, and an unencoded 1920 X 1080 movie file size is over 350 GB/Hour).
 

By 2010, forecasts call for 80-90% of Internet traffic to be video transfer.

Cable and the Phone Companies (DSL):

Cable broadband is capable of about 30 MBPS of bandwidth, however, speed can vary. Unfortunately, the measurement in real-world conditions can be more complicated. 

Median DSL speed in the U.S. is 768 KBPS. One type of DSL technology, VDSL, is capable of 30 MBPS bandwidth, but this service is not all-inclusive available. Instead, telephone companies more commonly offer ADSL or SDSL services (cheaper and slower).

Cable and the Phone Companies HDTV:

Verizon is building fiber-optic networks that will be capable of broadcasting handle 200+ HDTV channels in addition to all of the conventional online TV channels.

Most cable operators have enough available bandwidth for only about 10-12 HDTV channels without a major retooling of their networks.
