What is Digital Media? • • Digital Media is data which is stored, displayed and manipulated electronically. Digital Media can be converted to analogue format. Analogue media can be digitalised, allowing data storage and manipulation. Digital Media does not only exist on computers. . . References: (Vaughan, 2008)

Graphical Design • Graphics are visual still representations. • Graphics combine different ideas into a visual representation. • Graphics can be informative, educational, entertaining and artistic. • Digital Graphics are broken up into 2 categories: Bitmap and Vector. References: (Vaughan, 2008)

• Vector: Graphical Design Each individual object contained in a vector image is defined by a mathematical equation. This means that vector images are not resolution dependent. Thus, each vector object is scalable and can generally be resized without any loss of image quality. • Bitmap/Raster: Use coloured pixels to crate an image and are mapped according to their placement and colour. When stretched the image becomes blocky as the pixels are expanded. Reference: http: //www. tech-faq. com/vector-images. html http: //upload. wikimedia. org/wikipedia/en/a/aa/Vector. Bitmap.

Desktop Publishing • Desktop Publish is the use of a purpose built software to design and create a document for publication. • All Desktop Publishing software use a “What You See Is What You Get” (WYSIWYG) approach where all measurements and details are shown and used. • Desktop Publishing software integrates text, number and graphics into one final product. • This program can be used on a small scale by amateur users in the production of flyers or promotions or high end users producing newspaper articles.

Audio • Audio is a form of digital media that is converted from an analogue signal to a digital signal through the process of pulse code modulation. • The sound can then be converted to a variety of formats including the most common MP 3 or WAV. Reference: http: //www. tech-faq. com/pulse-code-modulation. html

Audio Pulse code modulation process is the translation of a microphone analogue waveform into a digital waveform. Red line represents the continuous voltage, and the stair stepped black line is the digitization process. Reference: http: //www. flickr. com/photos/ethanhein/2378146633/

Audio E-Music is usually available in the MPEG layer 3 (MP 3) audio format, which allows data to be stored with minimal loss of audio quality and with small file sizes. All digital data is stored in bits, where the greater the depth of bits the less of the original analogue signal is lost in the conversion process.

Video • Digital video is the process of capturing, manipulating, and storing of moving images that can be viewed on computer screens. • One very important advantage is offered through the digitization of video and that is the ability to edit and manipulate the content.

Video • The process involved in digital video production includes the following: • Camera and a microphone which capture the picture and sounds of a video session and send analogue signals to a video-capture adapter board. The board only captures half of the number of frames per second that movies use in order to reduce the amount of data to be processed.
