British Broadcasting
Britain’s broadcasting techniques has developed over time. We have a lot of different ways to broadcast media in the UK.
A popular method that is used by many is satellite. Satellites are popular because they orbit around the world in a circular or an elliptical way keeping connection interference to a minimum. It also has a large line of sight range, which means electro-magnetic radiation can travel far. Satellites are transmitted using microwaves, which are easily passed through the atmosphere. The benefits of satellites is that they don’t get interfered by hills or objects in front of them, they can give out signals without using radio waves, they transmit more channels for entertainment and also the quality of satellite is better signals transmit straight to your homes. Satellite usd to transmit analogue signals but are now digital. Most people in the UK use the Astra satellite group which is used by Sky, BBC and Free sat . Satellite is expensive
On the other hand terrestrial broadcasting does not involve using satellites or any cables but instead uses radio waves transmitted from the tower. Terrestrial broadcasting uses a tall transmitter placed in different locations. The reason why they are tall is so that they can reach a large area. The down falls of terrestrial broadcasting is that the antennas can’t be transmitted far like satellites, they don’t transmit over hills, signals may be lost if you travel away from the region the signals are being sent to and weather may affect the signals being sent out. As for satellites the signal is not lost as you travel because it is sent of from above land.
Cable TV transmits signals through fixed optical fibres or coaxial cables that go into peoples homes. Similar to satellite broadcasting you can get a wider variety of channels to watch but the drawbacks of having cable TV is that if your road has a certain cable type your home has to use the same. Cables can include packages of telephone, television and broadband this is a good way to save money also. A drawback of cable is that they are only allowed to install on type of cable into the road so everyone has to share the same network for example Virgin TV if they chose to switch to cable. Another drawback, like terrestrial broadcasting is that the weather affects the way the cable transmits to your TV. A benefit of cable TV is that it is cheaper than satellite and offers a wide range of channels. The cable network Virgin media is in high competition with the sattelite network Sky. Virgon media is the main UK cable provider, with 95% of the market.
Digital Broadcasting had been introduced to the UK not long ago. Digital broadcasting allows us to watch multiplex channels on 1 bandwidth which allows you to watch more than what terrestrial or cable TV can transmit lots of channels to your TV’s. Digital also have computers which encode TV signals into digital information, the information is sent as l's and o's pulses. These pulses can be compressed to take up much less bandwith then analogue, so more channels can be multiplexed together at baetter quality including HD (high definition) making it better quality. The bandwith that is left over is enough to transmit interactive information in the format of EPGs tec. The advantages of this are that there is more variety in channels which is good for the audience but not so good for the station because there is more competition.
Internet TV also known as internet protocol television (TPTV) was introduced to the UK around 2005. It is a lot different to all other broadcasting techniques as it is on demand plus you do not need a TV to watch anything all that is needed is internet connection or broadband. Broadband is an internet that is linked to your house phone so it does not lose internet or phone connection whilst both are in use. Internet TV is a popular way for people to view their favourite TV shows that they have missed or want to watch over from the start. Advantages for the audience are that they get to watch things when they want. TV is streamed and bufferd or downloaded. Stream and buffering is when you recivev the singals of what you are watching as you go. The show buffers which means taking in signals in and storing it as you go. Or people download the program/movie, downloading means when you get the whole thing on to the computer by downloading it. Another benefit is that the viewer can watch which episode or series of the particular program they want to view. An advantage for the broadcaster is that they can continue earning money by advertisements on the net so they do not lose out in money. A drawback would be that they are competing with other internet TV channels and also people may not watch TV as much. So their TV channels ratings may go down.
