"History of TV in the UK and abroad"

Television over the years has improved a lot, from the colour to the quality of the television. The analogue TV in the UK have channels 1 to 5. BBC 1, BBC 2, ITV 1, Channel 4 and Channel 5. 


Broadcasting Systems


The broadcasting systems consists of three different systems, PAL, SECAM and NTSC. When colour television was being introduced around Europe PAL and SECAM were created, this was after the 1950s. Before this NTSC had been introduced into America and Asia in 1941 and then introduced in colour in 1953. SECAM was the first to introduce colour television in Europe, and used a different way of transmitting colour to NTSC. However PAL being the standard for the UK improved the original NTSC method to transmit colour television. 


PAL stands for Phase Alternation Line. This is the UK stand in much of Europe, including United Kingdom. This is made up of 25 frames per second and it has 625 lines. 576 of the lines are used to show the picture.  

NTSC stands for National Television System Committee. This is the TV standard in the US. This is made up of 29.97 frames per second and 525 lines. 480 of the lines are used to show the picture. 

SECAM stands for Sequential Color with Memory. This is a French system that is very similar to PAL, however it sends colour signals separately.

"Have online videos lowered the standard of television production?"

There are some programs today which rely on footage that has been recorded from home, either on a mobile or video camera. This is not top quality footage but programs use it for the comedy which viewers will take an interest in.

For example programs such as "You've Been Framed" or "Rude Tube". They both consist of footage that has been recorded and sent in by people at home and approved to be shown on television for laughter of the viewers. This is not top quality and well staged productions as not a lot of organisation is needed. The only staged parts of these programs are the introduction of the program and cutting back to the studio in between clips to make a joke about the clip. This shows that a large crew isn't needed, nor is a studio needed as this could easily be recorded in the home of someone's, to show there enjoyment of the show too.  Also, other programs such as "Harry Hills, TV Burps" consists of footage from television to add a joke along side it. This footage could be taken of On Demand channels to show on their program. This doesn't need a lot of rehearsals as it is pretty much laid out in front of them what is being shown on the program.



These clips that are being added to the programs such as rude tube are not top quality but viewers still seem to be watching it, this shows that quality of the show doesn't seem to bother them, as long as its entertaining them. Although the digital world is improving everyday and now a lot of television is in HD, viewers still seem to be picking the low standard video recordings. This lowers the amount of crew and talent needed for a production as it is already produced for them and replacing large productions which spent more time developing their program.

"How has the digital world change the way we consume and create TV?"

Digital TV to the Viewers



Since the development of the digital world, the amount of different channels there is for the viewers has risen by a big percentage. There is a wide range of channels for the viewers now than many years before. Also analogue channels have risen to five which gives people who still have an analogue TV a wider range of channels than the couple they had before the development. 

Examples of ways the digital channels were introduced were through satellite TV such as Sky and Cable TV such as Virgin and BT vision. Viewers who changed from analogue TV to Digital TV went from only having five channels to a wide range of nearly eight hundred channels. Television was now broken down into categories such as documentary, sport, music, news, children, radio and many more genre categories. This made TV more enjoyable for viewers as they could easily find what they felt like watching. Also, some of the five TV channels that were available on analogue TV have developed and made other channels for their channel, such as BBC 1 now has BBC 2 BBC 3 est. and ITV has developed channels such as ITV 2 and ITV 2 + 1. This shows over the years that not only have channels risen rapidly that channels are developing.

        

            



Digital cameras over Film/Video cameras


There are many advantages to using digital cameras instead of film cameras. Digital cameras have much more advantages than film cameras to getting a better shot of what they need.





Digital camera let you upload photos you have taken on your camera onto a computer by a simple lead that comes with the camera or by using a memory card which a camera holds. This is a big advantage as it lets you upload photos on to blogs, social networks and other websites by a simple click of a button without any development. Also, uploading them onto your computer allows you to look at the photos before paying for them to be developed professionally. However film cameras can be a long process, as well as not being certain on what the photo looks like, you have to develop the film, this can be done within some photo shops which you have to pay for or can be done in your own dark room. It can be a long process as the film needs to be developed onto photographic paper then mixed in developing inks. This is a much longer process than the simple uploading onto a computer done by a digital camera. Also, on digital cameras there is a little screen with allows you to view the photo you have taken immediately so you know whether the photo needs to be taken again, however on film cameras you cannot see what you have taken until it is developed so this could end in being a waste of money if the photo is not what they wanted. 


Also, other advantages of using a digital camera is that if you wanted to record something, you can use the digital camera, as they have many different options of how you want to use your camera. So a simple change of settings and you can record what you like. Whereas you would have to take a video camera out as well as a film camera if you were changing between  the either of them. On digital cameras you can set the scene up, for example, if it will be a night shot, a close up, or beach scene, you can change the setting so nothing is lost in the shot due to brighten or darkness.  Also an advantage of uploading the photos onto your computer from a digital camera is that you are guaranteed a copy of the photo somewhere else as well as on the memory on your camera so you will not loose any photos, where as when developing the photos from a film camera is you only have the negatives which could easily be lost.


Editing in the Digital World


Editing is a big advantage to companies when producing a TV program. This allows them to record a wide range of shots then edit them together in post production to make their program look the best. This also allows them to cut out any mistakes and make sure the program runs smoothly together so there is no mistakes. Within editing you can also add you own effects. For example in a comedy program if funny sounds are being used and music is being added you can do this all in post production and add it where ever you need it. All special effects can be added during the editing of the program, other effects are brightness, contrast, airbrushing and sound effects. All this allows them to twig all the mistakes and add all the effects needed to make the program they are producing perfect and ready for showing.
