3DTV: A 3D television is a television set that employs techniques of 3D presentation, such as stereoscopic capture, multi-view capture, or 2D-plus-depth, and a 3D display a special viewing device to project a television program into a realistic three-dimensional field.
There are several techniques to produce and display 3D moving pictures. The basic requirement is to display offset images that are filtered separately to the left and right eye. The viewer wears eyeglasses to filter the separately offset images to each eye, or have the light source split the images directionally into the viewer's eyes that means no glasses are required.
Some 3DTV's are:
- Anaglyphic 3D
- Polarization 3D
- Alternate-frame sequencing
- Head-mounted display
- Without lenses: Autostereoscopic displays, sometimes referred to commercially as Auto 3D.
Satellite: Satellite television is television programming delivered by the means of communications satellite and received by an outdoor antenna. In many areas of the world satellite television provides a wide range of channels and services. The UK satellite provider is SKY.
Cable: Cable television is a system of providing television programs to consumers via radio frequency. The UK cable provider is virgin.
Analogue: Analogue television is the analog transmission that involves the broadcasting of encoded analog audio and analog video signal, one in which the message conveyed by the broadcast signal is a function of deliberate variations in the amplitude and or frequency of the signal. In the UK all the tv used to be analogue but then they had the digital switch over.
Digital: Digital television is where you transmit audio and video by digital signals. Many countries are now replacing broadcast analog television with digital television to allow other uses of the television radio spectrum.
Film-based:
CGI: Computer-generated imagery is computer graphics or more specifically 3D computer graphics to special effects in art, video games, films, television programmes, commerical and printed media. The visual scenes maybe dynamic or static.

Interactive: Interactive television has a number of techniques which allows the viewer to interact with television as they watch it.
Internet: Internet television is the digital distribution of television content via Internet. Internet television is a general term that covers the delivery of television shows and other video content over the Internet. Internet television allows the viewer to choose the content or the television show they want to watch or a channel directory. Two forms of viewing Internet television are streaming the content directly to a media player or downloading the media to the viewers computer. You can watch 4OD and BBC Iplayer online. iplayer and 4OD is good for me as if i miss a programme i can watch it on my laptop a different time or a different day, and catch up on the programmes ive missed.
High definition: High definition television is the video that has resolution substantially higher then that of traditional television systems. Earlier HDTV broadcasting used analog techniques, but today HDTV is digitally broadcast using video compression. In my opinion paying £10 a month to watch a programme in Hd is a waste of money as its just been filmed in HD to be put in normal tv.
Streaming content: Streaming content means to deliver media.
On-demand viewing: Video on demand allows users to select watch and listen to video and audio content on demand. Television video on demand systems either stream content through a set-top box, computer allowing viewing in real time or download it to a computer or a digital video recorder.
Programmes that have on demand viewing are BBC, ITV, Channel 4 and Channel 5.
