Camera Test

1. Increasing the gain on a camera can: add more artificial light to the footage, although as there is more light added there footage becomes more grainy.

2. Shutter speed should be set to 50

3. If you increase shutter speed that means less light will be let in. So as you increase the shutter speed you MUST add much more light. This allows you to add a smooth slow-motion in post production

4. White balance insures that the colours are more natural.

5. Increasing the audio gain can let more in and ups the volume of the audio, although this may distort the audio.

6. To fully focus the camera you should do expanded focus on the subjects hair as it is the most detailed thing on a person, then the focus on the subject should be good.

7. You would use the ND filter when there is too much lighting in an outdoor shot, as this filter works like sunglasses to the camera. It is crucial to remember that the lighting cant be changed in post-production.

8. If shooting in dark location,

Broadcasting Systems

Broadcasting

Broadcasting is the content of audio or video being distributed to the audience. This can all be achieved through the use of television, radio or other it is most common to be used so often is digital transmission media. The people who receive this tend to be the general public.

Forms of Broadcasting

There are many forms of broadcasting systems. These being; Telephone, Radio broadcasting, Television, broadcasting, Cable, radio, Satellite, Television and Webcasting.

Bandwidth

The range of the signals in broadcasting is titled ‘bandwidth’. Bandwidth being the difference between the lower and the upper frequencies. It tends to be measured in hertz. Bandwidth is key concept in any telephony applications

Narrowcasting

The total opposite of broadcasting, which is to a large number of people is narrowcasting which is the transmission of the data to a certain selection of recipients. A good example of narrowcasting is ‘cable’. This is because the signals for cable are sent only to certain homes which have subscribed to the service. The contrast as supposed to the cable would be terrestrial TV which uses a model of antenna which receives the signals from the broadcast model. This is available to everyone Who owns a ‘terrestrial TV’

 Radio waves

Radio waves tend to be sent from the transmitter to an antenna and the to the receiving device, which is most commonly used in radio broadcasting.

Television broadcasting

The first television broadcast in Britain was made by Baird Television system over a BBC radio transmitter in 1929. Baird only allowed five programmes on a day by 1930. 

Due to the Second world war in 1939, BBC was suspended for six years from September1st 1939 until June 7^th 1946.

Satellite television

(Direct broadcast satellite)

Satellite television is also referred to as ‘direct broadcast satellite’ allows people to receive hi definition interactive television. There will also be no worries about terrain getting in the way of the signal. An example of satellite television could be Sky TV.

Cable Tv

Can arguably be classed as broadcasting or narrowcasting ?

Cable television is the system which provides television to consumers using radio frequency signals which are transmitted to there televisions using fixed optical fibres. This is very similar to the over-the-air method which is used for the traditional television broadcasting, although an antenna is required. A good example of cable is ‘Virgin Media’.

Digital Broadcasting

Digital broadcasting is the practice of using data which is digital as supposed to analogue waveforms in order to carry broadcasts over the television channels. Digital broadcasting tends to use a ‘multiplex’ which allows us as the audience to view several channels together all running through one bandwidth.  An example of this being Freeview

Convergence.

Convergence is when two things come together and form one strong outcome. A very good example of this is when Internet came together with tv to form internet TV.

Internet TV

Internet television is when TV is distributed through the internet. This is growing to be very popular in the 21^st century. It is very beneficial as it is very convenient, I say this because it is at our finger tips and we can view it in our own time.

Personally out of all of these I would prefer internet TV and satellite television, I say this because it seems to be the most responsive as compared to the others. This is because of the quality of the both of them is of a high standard. Also internet TV is more practical for the audience. Also satellite TV is less to worry about the signal being interfe

Aspect Ratio

Aspect Ratio

16:9 (WIDESCREEN) has been used from a long time ago. It has only been brought to TV within the last decade or so. 16:9 offers more panoramic experience to see more of the subject and its surroundings.

The image to the left  shows a wide screen. In order to convert the above to the ratio 4:3 you have to crop the 16:9 image, which is given the term ‘Pan & Scan’. This is not a good way to convert the ratio, as it loses the essence of the footage which is being converted. This is because some essential things which the director tried to achieve may not be seen due to it being cropped out of the image in the process of the conversion.

Converting 4:3 to 16:9

To convert 4:3 to 16:9 you have to re position the video image and center it whilst adding a pillow box to either side which keeps it in the same resolution not changing the image in any way or form. There is also another way of resizing/re positioning it but it may lose its resolution/pixels. This is because the image is made up of loads of small dots which form the colours we see.

The two terms for the process of size conversion can are called letter boxing and pillow boxing.

*Pixels*

If u where to zoom far into a image you will see that the image is made up of a lot of coloured dots which your brain rearranges to create a understandable image.

Frames per Second (FPS)

Frames per second are still images which are run at a high speed in order for it to look like video footage.

The tv screen.

A TV screen is made up of 525 horizontal scan lines which make up each individual frame. Each individual line is made up of *pixels*.

Demonstrate your knowledge of digital televison?

Digital television has made a huge impact on the public, this being the change in quality which allows us as the audience to experience the shows we used to view, in different aspect ratios at different qualities and also we have the ability to view them at any time with the 'on demand' facilities. An example of 'digital' making a big difference is that you can have hundreds of viewable channels as supposed to analogues five this is offering much more to the viewer.

Digital TV also allows the feature, interactive to also be used. On analogue all they had was teletext whereas digital allows you to view footage from different angles or even screen split so you can watch two or more things at once.

Also with the digital video editing abilities it is a dramatic contrast as supposed to the analogue methods. A good exmple would be trying to cross dissolve from one video to another. The process is much more easy if you where to edit is digitally, literally with the click of a button .
