This camera films from two different angles to make a 3D image. In cinemas special glasses are worn so that audiences can see the film in 3D, without them the audience would only see the twoshots on top of each other. In my opinion 3D isn't what all people want. Most people want an improvement in picture. 3D films may distract viewers from the actual film.
Satellite- The programs received by the TV is from a satellite or antenna. This type of receiver can receive channels that other services can't. As HD has been introduced, satellite TV has improved. The Uk's Satellite provider is SKY. Owners of sky would pay in installments to recieve the channels that are requested. Problems with satellite TV is that if weather conditions are bad, the reception would be bad.
Cable- The signals for cable are received through coaxial cable in the form of a radio frequency or digital light pulses through fixed optical fibres. Both found underground. These cable help analogue TV receive digital signals.John Walson and Margaret Walson in the spring of 1948 founded cable. Virgin is the provider in the UK for cable.
Analogue- This is the first type of signal that TV received and the later replaced by digital in 2008. The signals made are encoded. Only 5 channels would be received through and analogue signal. The quality is not as good as the digital signal but the sigal was much simpler. Now TVs are fitted with digital recievers as analogue has stopped.
Digital- Like analogue, digital television is received through signals, Digital signals carry audio and video. Digital has a better quality picture than analogue and has a bigger capacity. Unlike Cable and Satellite, Digital is received through and aerial like analogue. In my opinion I believe Digital is an improvement and more reliable.
Film based- Technology for film making has advanced dramaticly over the years. Colour, picture and audio have improved alot, making a better film experience. Also 3D films have become more popular over the years. Special effects, animation and visual effects have improved so much over the years.
Interactive- Interactive TV has become more popular over the years. We are able to watch sports from different angels and we are able to vote in competitions through the 'red button'. The BBC's red button provides viewers with news about the weather, sports and other news. These can just be accessed by using the remote. Sky interative is a very popular with SKY viewers, they can play games and other activities.
Internet- The Internet is where most information can be found. In recent years TV can be watched through the Internet on catch up websites or even live streaming websites. Sometimes programs could be watched illegally online. On demand and streaming videos can be found online.
High definition- HD TV is a higher quality of TV than normal TVs. These TVs have a clearer image and have two million pixels per frame. TV broadcasters have made alternate channels for viewers with HDTV by creating HD channels. This is that HD viewers are receiving the best picture for what they have bought. They have not made their original channels HD as not all families and homes have a HDTV. The following video tells us how high definition works.
Streaming content- This new way of receiving media has revolutionised TV viewing. People with smart phones are able to receive programs like the news and other programs. Some of this content is live. This way of receiving TV can be bought as an ap. Internet information also can be streamed.
On-demand viewing- This is where people go online, onto websites like 4OD and BBC I player to watch pre-recorded programs that they may have missed on TV. These programs can be watched by Internet. People with a set-top box can ask for different programs for a certain amount of money, very similar to pay per view. Some viewers who have hearing difficulties can request subtitles through on demand or a person the
Digital recorders- This technology can record digital TV on to a disk drive, memory, mass storage ect. It also can replay recorded information. Some recorders can also record cable TV. In some recorders a mass amount of storage.
Pay per view- This is where a person can pay for a certain channel or viewing of a program for one time only. You can pay by an on-screen guide, an automated telephone system, or through a live customer service representative. Usually films and sport events are bought using Pay Per Viewer.
CGI- Computer Generated Imagery is applied in many forms of media; film, TV, art....ect. CGI helps make the impossible, possible in films. CGI films take a very long time to make. There are many ways of creating CGI based films such as stop motion animation and the use of green screen. The computers that the public have at home are now able to access software that can make CGI films.
