3D TV is the newest in the ongoing range of television improvisiation techniques. Basically a 3D television is a tv that uses special technology to create a 3 dimentional aspect right in front of the audience, more often than not this is with the use of special 3D glasses. There are a number of ways to create a 3D image, the way it is done by the television companies involves displaying two images to each eye for example by using specially designed polarization or anaglyphic glasses in order to see each image in seperate eyes which creates the illusion of 3 dimentional images to the viewer.

Satellite
Satellite TV is a method of receiving Television channels by using a communications satellite transmitting to an outdoor satellite dish. This is then run through the building and played to the TV through a reciver that comes as a set top box or a satellite tuner. The main problem with satellite tv is that the quality of the transmittion can be disrupted by weather and other issues a lot easier than reciving methods like cable.
Cable
Cable TV is a method of transmitting television programs using Radio Frequency signals (RF signals). Televisions recive the signals through special cables or even digital light pulses involving special technology hence the name cable. The main difference between cable and other methods is the change of radio frequency signals used. This method can prove better than mehtods such as satellite because the cables are underground and therefore less likeley to recive any disturbance.
Analogue & Digital
Analouge Television
analogue television is basically the analogue transmission involving broadcasting analouge audio & video signals. Analogue is now far outdated by digital television (DTV), however at its time it was the main source of television. Basically analogue takes a television picture inlcuding sound and animation and encodes it then transmits it as an analogue signal.
Digital Television (DTV)
Digital Television is another transmission of audio and video this time however it is done by using digital signals. Many places in the world have now changed their tv setup to digital with no analogue signals. A main reason for the change is because the quality of digital is better than analogue.

interactive
Interactive TV is basically a way of watching what you want when you want to watch it instead of waiting for a program you want to watch comes on tv. For example sky has something called sky active which is basically the companys name for skys interactive features such as games, shopping and more all on the TV.
High definition
Internet TV, often mixed up with web TV (Short episodes/clips made only for online viewing) is basically just a way of watching television on the internet anytime. It was created as a catch up method in case people missed an episode of an ongoing series; however now it is more advanced and often used for watching tv via a computer. Common examples of this are websites like 4oD, BBC iplayer, Itv player and others. I think that Internet TV is a very good idea because it allows people to watch what they want, when they want using technology that almost everybody has access to.

High definition
High definition TV (HDTV) is just video that has a lot higher resolution to the resolution of regular TV (standard definition) The first high definition TV broadcasts used analogue signals but now however High definition is broadcast via digital signals using video compression. HDTV has roughly one to two million pixels per frame This impressive ratio is around 5 times that of the standard definition.
film-based
CGI
Computer generated imagery (CGI) is a method of using computer graphics in films, games, Tv and other aspects of the media. CGI is a very advanced method capable of creating 3D computer graphics that look very realistic. The technology is so advanced that recent updates have allowed people to create certain professional grade films & games from their home computers. An example of CGI would be for example Toy Story; everything in toy story was computer animated including the characters. The part that can take a long time is when the film has to render it allegedly took toy story around 6 hours to render 1 frame and there are roughly 25 frames per second.
