Digital Media Products
There are a large variety of digital media available for our use and our enjoyment.
Desktop Publishing Magazine: Desktop Publishing magazines are developed using program such as Adobe InDesign or QuarkXPress. The Desktop Publishing Program (DTP) are also called a ‘Page Layout Program’ or ‘Publishing Program’ which gives full page design options including style, rules, borders, page, numbering, columns, and a key feature is the capability of flowing text around objects in a variety way providing ultimate flexibility. This in turn collaborates graphic images and text into one component like a newspaper or magazine. Often the magazines are either printed or now available online as PDF files .The benefit has been that more and more people can create newspapers at home instead which shows that the cost has been brought down, furthermore there are templates available for many common tasks to be developed efficiently.
Newspapers: Newspapers are usually created using desktop publishing magazine or other digital media programs available .Newspapers are created on a daily basis in large offices usually in the bigger cities of the world. Newspaper teams consist of many people and the newspaper has to be top notch in terms of quality of article and the layout which is created using programs such as Adobe InDesign or QuarkXPress.
Graphical Design: Graphical design are usually related to two main graphics types’ bitmap and vector graphics. A bitmap is a digital image composed of many dots which correspond to an individual pixel on a display .Together these dots create an image usually of a rectangular shape. Bitmapped graphics are edited using a painting program where you can zoom in on a particular pixel to your particular liking. Bitmap images can create high quality images though when zoomed in images will appear blurry. The common file formats for bitmapped graphics include BMP, JPEG, GIF, TIFF, PNG and PICT.
Vector graphics are created in graphics packages and consist of shapes called objects and lines. They are edited and constructed using a drawing program and you can edit each object separately, for example, change the shape, colour, size, width, pattern and position. Even if an object in a vector graphic is quite large, it doesn't need a lot of computer memory. Therefore the file size of a vector graphic is often very small. Vector graphics are scalable meaning when you resize them, they do not lose quality. The major file formats for vector graphics include CDR, WMF, EPS and PICT.
Audio Sequences: Audio is sound within the acoustic range available to humans and can be captured with a microphone. An audio frequency is an electrical alternating current within the 20 to 20,000 hertz range that can be used to produce acoustic sound. In computers, audio is the sound system that comes with or can be added to a computer. Sound travels with three features being the wavelength; being the distance between each wave cycle, amplitude; the height of the wave giving sound its volume and frequency; the number of wavelengths in one second. An audio card contains a special built-in processor and memory for processing audio files and sending them to speakers in the computer. An audio file is a record of captured sound that can be played back and a short piece of sound is known as a sequence. Sound is a sequence of naturally analog signals that are converted to digital signals by the audio card, using a microchip called an analog-to-digital converter. When sound is played, the digital signals are sent to the speakers where they are converted back to analog signals that generate varied sound. Audio files are usually compressed for storage or faster transmission. Audio files can be sent in short stand-alone segments. In order for users to receive sound in real-time for a multimedia effect, listening to music, or in order to take part in an audio or video conference, sound must be delivered as streaming sound. The most popular audio file format today is MP3.
Animation Sequences: Animation sequence is a simulation of movement created by displaying a series of pictures, graphics, or frames. Cartoons on television is one example of animation. Animation are key features of multimedia presentations. AN animation can created with a number of programs and when created the size of the file and the speed of the animation effect and are key aspects. The main file formats include SWF, MOV and animated GIF. The use of animations is to show another way to the viewer of how to learn, a demonstration or the process being shown in a series of animations and to interact the viewer with the animation. This is a fun and engaging way for everyone to learn.
Musical Composition: Musical composition is where music is created and composed using digital media programs and software’s. Musical Instrument Digital Interface (MIDI) is a common way that computers and electronic music instruments combine to create a vigorous sound. The interface can create a composition of up to 16 instruments to be able to play in sync. Musicians uses a MIDI instrument to adjust and play music on a computer and therefore being able to save and edit the music later when needed. The advantage of MIDI files is that they don’t need so much storage space and are still producing quality sound trusting on the sound card or synthesizers used to play the music.
Video Production: Video production is the process of converting an idea into a video. The person who manages the production process is known as the producer. Usually video production is created using video clips or sequences from a digital video camera and later on in the process editing with a software. The video clips consist of many frames that contain images which are then played in sequence. A video production also involves audio, images to a timeline. It involves the following editing processes: Transitions,Trimming Videos,Splitting Videos, Combining Videos, Video Effects, Adding pictures or audio, Adding titles, credits or onscreen text.

Common File Formats
There are many file formats available today. Below is a varied list of the file formats for the specific product.
Bit mapped graphics
BMP- Short for "Bitmap." It can be pronounced as "bump," "B-M-P," or simply a "bitmap image." The BMP format is a commonly used raster graphic format for saving image files. It is now recognized by many programs on both Macs and PCs.
JPEG- The term actually stands for "Joint Photographic Experts Group," because that is the name of the committee that developed the format. A JPEG is a compressed image file format. JPEG images are not limited to a certain amount of colour which is best for compressing photographic images.
GIF- "GIF" stands for "Graphics Interchange Format," which is a compressed image file format. GIF images use a compression formula originally developed by CompuServe. GIFs are based on indexed colours, which is a palette of at most 256 colours. This helps greatly reduce their file size. GIF files are great for small icons and animated images, but they lack the colour range to be used for high-quality photos.
TIFF- "Tagged Image File Format” is graphics file format created in the 1980's to be the standard image format across multiple computer platforms. The TIFF format can handle colour depths ranging from 1-bit to 24-bit. Since the original TIFF standard was introduced, people have been making many small improvements to the format, so there are now around 50 variations of the TIFF format.
PICT- A file format developed by Apple Computer in 1984. PICT files are encoded in QuickDraw commands and can hold both object-oriented images and bit-mapped images. It is supported by all graphics programs that run on Macintosh computers.
Vector graphics
CDR- Stands for "Compact Disc Recordable." CD-R discs are blank CDs that can record data written by a CD burner. The word "recordable" is used because CD-Rs are often used to record audio, which can be played back by most CD players. However, many other kinds of data can also be written to a CD-R, so the discs are also referred to as "writable CDs."
WMF- Short for Windows Metafile Format, graphics file format used to exchange graphics information between Microsoft Windows applications. WMF files can hold both vector and bit-mapped images.
EPS- Stands for "Encapsulated PostScript." EPS is a PostScript image file format that is compatible with PostScript printers and is often used for transferring files between various graphics applications. EPS files will print identically on all PostScript-compatible printers and will appear the same in all applications that can read the PostScript format.

Audio
WAV- The format for storing sound in files developed jointly by Microsoft and IBM. Support for WAV files was built into Windows 95 making it the de facto standard for sound on PCs. WAV sound files end with a.wav extension and can be played by nearly all Windows applications that support sound.
MP3- MP3 is popular compressed audio file format that helped popularize digital music downloads beginning in the late 1990s. MP3 files are typically about one tenth the size of uncompressed WAVE or AIFF files, but maintain nearly the same CD-quality sound. Because of their small size and good fidelity, MP3 files have become a popular way to store music files on both computers and portable devices.
WMA-Short for Windows Media Audio, a Microsoft file format for encoding digital audio files similar to MP3 though can compress files at a higher rate than MP3. WMA files, which use the ".wma" file extension, can be of any size compressed to match many different connection speeds, or bandwidths.
Animation
SWF-SWF is a file extension for a Shockwave Flash file format created by Macromedia and now owned by Adobe. SWF stands for Small Web Format Files which contain video and vector based animations and sound and are designed for efficient delivery over the web.
MOV- Common multimedia container file format developed by Apple and compatible with both Macintosh and Windows platforms; may contain multiple tracks that store different types of media data; often used for saving movies and other video files; commonly uses the MPEG-4 codec for compression.
GIF-Above
Video
MPEG- Short for Moving Picture Experts Group, and pronounced m-peg, is a working group of the ISO. The term also refers to the family of digital video compression standards and file formats developed by the group. MPEG generally produces better-quality video than competing formats, such as Video for Windows, Indeo and QuickTime.
AVI- Audio Video Interleave is a multimedia container format from Microsoft that has been widely used for video playback in the Windows world. AVI was the first A/V format for Windows. Based on the RIFF format, AVI is known as a "container format" because it is used for multiple encoding methods, not just
WMV-Short for Windows Media Video, WMV is a video compression format developed by Microsoft that utilizes multiple video codecs for streaming of video on the Internet under the file extension .WMV.
