File Format

File formats are the various ways in which files can be saved. The format that you choose to save your file as depends on its content, size and quality. For low quality windows media files, you would save them as.wmv. If you were saving a PowerPoint, you would save it as a ppt. file. There are many different file formats, but no matter what format you save it as, the higher quality the file is, the more space it will take up.

Compression Techniques

Data compression involves encoding information using fewer bits than the original representation; Compression can be either lossy or lossless.

Lossy compression reduces the file size by identifying unnecessary information and removing it. Although this produces the smaller file size, it can result in images becoming distorted. For example it could be reduce the colour space to the simplest colours in the image, resulting in 6 or 7 colours rather than 256.

Lossless compression reduces the file size by identifying and eliminating any wasted "space" used to transmit the data. It produces a larger file size, but overall the image quality a lot better. For example, an image may have areas of colour that do not change over several pixels; instead of coding "red pixel, red pixel, ..." the data may be encoded as "279 red pixels".

Image Resolution

Image resolution refers to the sharpness and clarity of an image. The higher the resolution the sharper, more defined, and more detailed the image will be. However, an increase in resolution also leads to an increase in file size. This may pose a problem if you are looking to display the image on a website, as the file size might be too big. A higher resolution is therefore better for image quality, but it also leads to an increase in file size.

Colour Depth

Colour depth refers to the levels of colour that are found in a graphics display. The greater the colour depth, the higher number of pixels used to show the colour of a bitmap image. A higher colour depth therefore leads to a better quality image with more intricate colour and the definition, but it also leads to an increase in file size, as there are more colours and details being expressed.

Copyright: An owner of a piece of work, ranging from poetry and stories, to videos and images, can copyright it. This means that anyone who wants to incorporate the piece into their own designs and ideas needs the permission of the original author or has to pay a fee to use it. Copyright laws are in place to prevent people plagiarising other peoples work and claiming it as their own. What some people choose to do is buy rights to use the piece of  work and then put their own spin on it to make it their own.

Copyright Free: Work that can be freely used by anyone without fear of copyright punishment by the author. There are 3 ways in which a piece of work can be copyright free:

1. Copyright was never attached to the work.
2. The copyright was attached but has since expired.
3. The owner of the copyright has permanently surrendered the right to enforce the copyright. 

Intellectual Property:  A concept in law which allows the author to protect an ‘idea’. This could be anything, including a brand, an invention, a design, a song or another intellectual creation. It is described as ‘property’ because, just like other property, it can be owned, sold, transferred, leased or given away.  

Trademark: Trademarks are used to claim exclusive properties of products or services. If the trademark is offensive or falsely advertises however, then the owner may face legal action. Trademarks can be licensed as well as owned. For example: The Lego Group purchased a license from Lucasfilm in order to be allowed to launch Lego Star Wars. The unauthorized usage of trademarks  is known as brand piracy and the owner of the trademark may pursue legal action against trademark infringement. Most countries require formal registration of a trademark in order to pursue this type of action. The United States, Canada and other countries also recognize common law trademark rights, which means action can be taken to protect an unregistered trademark if it is in use. Common law trademarks offer the holder less legal protection than registered trademarks however.

Unit 43 - Task 5

Below is a list of all the images I have used on my director file. I have referenced the location of each video and image I have used. In order to avoid breaching any copyright regulations, I emailed each company to ask for permission to use their images. Some of the videos I have taken myself, therefore I am not in breach of any copyright regulations.
