That may sound a tad dishonest, but it's not different to adding extra detail with high definition cameras. 3D has broadly the same aim; though technically speaking it's completely different to HD.
With 3D glasses on, each eye sees a slightly different image; your brain does the rest in creating the illusion of both depth and 'front' effects in what is obviously a completely flat image.
Satellite television
Satellite TV is a broadcasting service which allows subscribers to receive television signals through a dish-shaped receiver unit. These signals are originally uploaded to a communications satellite that is in a fixed orbit above the earth, then electronically scrambled to prevent unauthorized downloading. Those who pay a subscription fee for satellite TV service are issued both the receiving dish and a descrambler. The actual tuning information is fed into the television through a cable, much like the earth-bound cable television services in competition with satellite TV providers.
Cable Television
Cable television is a system of providing television programs to consumers via radio frequency (RF) signals transmitted to televisions through coaxial cables or digital light pulses through fixed optical fibers located on the subscriber's property, much like the over-the-air method used in traditional broadcast television (via radio waves) in which a television antenna is required. FM radio programming, high-speed Internet, telephony, and similar non-television services may also be provided. The major difference is the change of radio frequency signals used and optical connections to the subscriber property.
How its changed over the years
since the 1950's, tv has been developing constently , for example - tv's originally were in black and white, then they introduced colour tv witch was big back in the day , then they seeked into developing the defenition (HD) witch was also a big hit and most people at the moment use HDTV's.This effected peoples perspective on TV and how there eyes see the tv.Another recent developing scheme is 3D (3 dimensional) witch allows viewers to see almost asif its real life.
what the future holds for increase in technology
I think tv's wont develop alot from now on but i do think they will bring touch screen sensitive to tv's and also like the technology on xbox 360 connect were you can move certain object by moving your self body or even voice command.Because theres not much they can do now with tv's i think they'll focus more on making them to the biggist size suitable meaning width and hight.
HDTV
Short for High-Definition Television, a new type of television that provides much better resolution than current televisions based on the NTSC standard. HDTV is a digital TV broadcasting format where the broadcast transmits widescreen pictures with more detail and quality than found in a standard analog television, or other digital television formats. HDTV is a type of Digital Television (DTV) broadcast, and is considered to be the best quality DTV format available. Types of HDTV displays include direct-view, plasma, rear screen, and front screen projection. HDTV requires an HDTV tuner to view and the most detailed HDTV format is 1080i.
would i buy this new technology?
with new exclusives such as 3DTV's , the argument is ... is it worth getting with not many channels in 3D? and its an extra cost, personally i wouldnt until its either cheaper or it reaches to a wider broadcast.On the other hand i think HD is worth an extra tenner more because channels or even football matches are more clear and i have a satisfied view of the tv.
