How has the digital world changed the way we consume and create tv?

The digital world has changed a huge amount in the last 10 years. There are now many ways that you can watch TV. Terrestrial TV is a type of way you can watch TV. Terrestrial has 5 channels and is received through radio waves. In the UK this is received by PAL.

Another form of watching TV is through cable this is received in a different way, it is received through radio frequency signals and is transmitted through optical fibres and coaxial cable which is put underground. This means that there is no satellite dish needed.

Satellite is another way; this is received through a satellite dish and a set-top box. By having satellite you can choose what channels you want to watch to what suits you. You also have to pay monthly for satellite TV.

Digital terrestrial is received through aerials just like terrestrial TV but this can receive more channels then just your five analogue channels. To get the more channels you have to have a freeview box connected to your television. This has a multiplex transmitter so it can receive the more channels.

Multiplex is another way of watching TV this is a group of channels that are mixed together for broadcasting over a digital TV channels and then are separated again by the receiver , which then transmitters them so it can be watch on TV.

As well as watching your TV shows on TV you can now watch them in different ways-

IPTV (internet protocol television) this is TV that is received by the internet. This allows people to watch live shows online, or to catch up with shows that have been on a few days ago.

Video on demand is similar to IPTV but you can’t watch live TV. This allows you to watch past programmes when it suits you. This can be received through the internet. An example of this is BT vision to get this you must have a vision box.

This is BBC iplayer which allows people to watch tv when they want to.

Over the past few years digital cameras have become more popular over the video/film cameras. There are many advantages from using these as they give the filming better qualities’ digital camera uses a SD card where as a video camera uses a HDV tape or a miniDV tape. With video/film cameras the tape can only be used once to have a good quality where as if you use a CD card they can be used until the card is full. Once it is full, filming and images can be deleted and the card can be used again with the same quality. In the long run digital camera have a much bigger advance as you don’t have to keep paying for the tapes as you can re-use the SD cards. A digital camera also allows you to delete any shot that you don’t want when you are out filming so it’s not wasting space, whereas on a DV tape you can’t do this. You can also change things while out and about, for example you can change the white balance.

The way TV has been shown on TV has changed a lot. Pre-recorded TV shows have an advantage of making them better by editing the show. This improves the shows so that they can cut bits out and can make sure that shots are to the best quality. Many shows will use the apple software “final cut pro” to edit there shows. Editing allows film crew not to shot things in order. So if they can spend one day in one place and they can film everything even if it’s not in that order.  So if they can spend one day in one place instead of going back and forward to somewhere, this can save companies a lot of money. When they come to editing they can then put them in order.
In the last 10-15 years editing has become a big part of post production. Editing lets the show rearrange shots, use colour correction, sound missing and adding voice over’s to the clips. This has improves the digital world a lot as its able’s companies to make the shows better quality.
