Developing Technologies in the TV film industries
TV has come a long way in the last couple of years, like having more things to offer such as 3d television and surround sound and bigger televisions.
3d Television: A television set that captures two seperate images and puts them together, this device has been created to project a television programme into a realistic three dimensional programme.
To view programmes in 3d you are required to wear glasses this is so they can display offset images to each eye or if no glasses are require then they have the light source splitting the two images directly into the viewers eyes.
At the moment 3d television is not very popular as not many households have them, i believe this is because it isnt really a good value for your money, as not many programmes are shown in 3d so it would hardly get used. i have never seen a television programme in 3d but i have seen films in 3d and i do not think that 3d films are much different to normal films, also i dont think you should have to pay extra to see a 3d film as its not the veiwers choice for that film to be in 3D it was the producers so i dont think the veiwers should have to pay extra.
Sattelite Television: Sattalite television usually works by having a sattelite dish outside the veiwers house, sattalite tuners are also available with a card or USB stick to be attached to computers. However as sattelite dishes are placed outside, they arent always very functional as when the weather turns bad, sattalite preview is limitted and goes off. So its not verry reliable. An example of a sattelite tv company is SKY.
Cable Television: Cable television is used by sending signals to televisions through either coxial cables or digital light pulses through fixed offset optical fibres located under ground. I used to have Sattalite but now have cable and I believe that cable is better than satalletite as it is more reliable and has more to offer such as on demand and Tevo, however not all people can have cable as they need to have coxial cables in their area and as not all people do they have to stick with sattelite also cable television is a little more expensive but i believe that it is worth it. An example of Cable is Virgin Media
Analogue: involves broadcasting of encoded audio analogue and analogue video signal. All broadcast television sysetems that use analogue may be wireless or can require that copper wire is used by cable converters.
Digital Television: when video and audio are transmitted by digital signals, instead of the analogue signals being used by analogue TV. To allow other uses of the television radio spectrum many countries replaced broadcast analogue television with digital television.
Interactive Television: Usually used by ITV for voting shows, it gives the viewers the chance to get invloved in what they are watching. Sky has these features so you can interact and the ways of doing this is usually accessed by pressing the red button on a sky remote whilst watching any sky digital programme.
High definition television : showing videos in higher definition then what they are tradittionaly shown in. At first HD used to do analog techniques, but today HDTV is digitally broadcasted by using video compression.
Streaming Media and Internet Television/on demand viewing:
Virgin Media an example of a company that do on demand. Streaming Media gives people the chance to watch and catch up on any programmes they have missed and not had the chance to record. Live streaming,delivering live footage over the internet involves having to use a camera for the media, an encoder to digitilize the content, a media publisher and a content delievery network that distributes and delivers the content.
Internet TV: Sometimes known as online TV, however it should not be confused with Web television , as this only shows short programmes or short videos that have been created by a wide variety of either companies or undividuals. Some internet television is known as catch-up TV, or internet television. It covers the delivery of shows and other video content over the internet.
an example of a website that does this is BBCiplayer, this shows only BBC shows.
Digital Recorders:
digital tv recorders are a little similliar to videorecorders as you can record any television programmes that you want to watch another time, so you don't miss them. However as digital recorders are the newer version of video recorders they come with benefits, such as:
Pause Button - gives the chance to pause and re-wind live TV whenever you want.
Multiple Recording - instead of recording each individual episode belonging to a series you can record them all in just one touch.
Pay-per View: provides a service so that the audience can purchase events to view even though they are on the private telecast. The broadcaster shows the event at the time to everyone ordering it. An on screen guide can be used as a way for viewers to buy these or they can ring up and do it over the phone by an automatic pre-recorded system or do it live directly to a service representivs. The events they have to offer usually tend to include feauture films, sporting events and entertainment.
SKyboxoffice is a pay-per view channel.
