What is HIGH DEFINITION in TV and Film?
High definition is basically a different standard of digital television broadcasting which offers sharper, more detailed pictures and surround sound, making the overall experience much more enjoyable for the audience. Only viewers that own a "HD Ready" television set, a special HD set top box receiver and reception of a high definition service will experience true HD programming. Also high definition programmes must also be specially shot.
What are the different aspect ratios for TV and film? Which ones are better for TV programmes and films?
I have listed examples of which ratios are better for standard TV, HDTV and the ratios used standard films and bigger budget films.
Analogue composite video signals - In a composite video signal, a signal cable carries all the constituent parts of the video image. YUV is a common composite video signal type.
What are the different types of digital filming and storage?
Digital memory cards are used to store digital film, memory cards are removable, and quite a few different types are available. DSLRs mainly use Compact Flash, but other formats, such as SD cards, are becoming more popular. Compact cameras use a wider range of cards.
Different types of digital filming and storage are Compact Flash (CF), Secure Digital (SD)
Sony Memory Stick (MS), MultiMediaCard (MMC) / SecureMultiMediaCard (SecureMMC).
What was terrestrial TV? Why was it turned off?
Terrestrial TV is a type of television broadcasting using radio signals for transmission and television antennas and tuners for reception. Terrestrial television is the first system of television broadcast and the BBC began broadcasting in 1929, and had a regular schedule of television programmes in 1930. There was virtually no other method of television delivery until the 1950s with the beginnings of cable television. Terrestrial TV became outdated like many other things in life and something better was invented which was cable television.

Final Cut Pro review
I think that Final Cut Pro is the best editing software due to the large amount of people that use this software to edit videos and films, it is the most advanced editing system compared to the other two which I have gotten reviews for. For the price it is also popular because some of these others are around the same price but you can do so much more with Final Cut Pro. Apple are one of the biggest companies in the world and they know how to get people to buy there products, it is stated in the review that they have built a completely new faster, cleaner and more intuitive digital video editing package.
Which is better HD or standard definition, prove it with research?
HD is better than standard definition, this is because the visual is less pixilated, meaning the visual is clearer and it also makes smaller details blend into the action. Because HD is clearer it also means that key elements of the action that may be small but important are clearer and stand out more as the details are shown in a much better quality.
The standard for a TV programme is 4x3(1.33:1) - This is the standard Full Screen square TV size. Notice how much image is lost to cropping.
The standard for HDTV programming is 16x9(1.787:1) which relays on a resolution of 1920x1080 or 1.78:1. Film can still be cropped to fit on a 16x9 HDTV.
The standard ratio for a lot of movies you see in the movie theatre is 1.85:1. Which is only
slightly wider than 16x9.
2.39:1 - This ratio is also used in a lot of movies, usually the bigger budget movies as the film stock costs more.
What are
the different types of audio and video signals?
Analogue component video signals - This means video signals can be
split into two or more component parts. In a typical component video system the
signal will be divided into:
·
‘Y' or ‘luma' which is the brightness
portion of the image and travels along one cable
·
‘Pb' which gives the difference between
the luma information and the blue part of the image and has its own cable
·
‘Pr' is the final component and carries
similar information describing the difference between luma and the red part of
the image, again in a dedicated cable
A green signal is not required as it can be calculated from the other two colour components.
This common ‘component' system (or colour space) is known as YPbPr.

S-Video (Separate
Video) is another common form of component video. S-Video separates the signal
into only two parts; luma and chroma (combined colour information).
Digital component video signals - Video specifications
such as SDI (Serial Digital Interface) use a colour space very similar to
YPbPr. This is known as YCbCr. Again, luma, blue/luma difference and red/luma
difference form the coloured image, but in the YCbCr information is expressed digitally.
Analogue composite video signals - In a composite video signal, a signal cable carries all the constituent parts of the video image. YUV is a common composite video signal type.
·
In YUV the ‘Y' stands for
luminance. This monochromatic image contains more than just image
information: it also provides a synchronising ‘pulse'
·
The ‘U' value is the difference between
blue and luminance
·
‘V' is the red/luminance difference
In a
composite system all of this information is carried in the same cable (the
colour information is carried as a sub-carrier signal). YUV is versatile; it
contains a fully formed monochrome image for display on black and white
televisions.

What are the different ways we can record TV?
Recording digital TV has become easier these days to record analogue TV onto videocassette ever was. Now there is no need to look up dates and times and input the details all you have to do is just pick the show that you want to record and press the 'record' button. Other than recording TV by pressing the record button you can also buy a vintage video player/recorder and record things by using videocassettes. Plus DVD recorders are an option as they're quite cheap and easy to set up, although they probably won't interact with an electronic programme guide. There are also a number of different hybrid devices, such as Popcorn Hour which combines internet, hard drive and DVD recording.

You can see by this picture that the Standard Definition is poorer quality than High Definition.
