Multimedia Types And Tools
Multimedia is simply multiple forms of media integrated together. An example of multimedia is a web page with an animation. Besides multiple types of media being integrated with one another, multimedia can also stand for interactive types of media such as video games, CD ROMs that teach a foreign language, or an information Kiosk at a subway terminal. Other terms that are sometimes used for multimedia include hypermedia and rich media.
There are number of data types that can be characterized as multimedia data types. These are typically the elements or the building blocks of or generalized multimedia environments, platforms, or integrating tools. The basic types can be described as follows : Text, Graphics , Audio, Animation, Video, Graphic Objects (see: Computer graphics and visualization).
Types Of Multimedia
Text – The form in which the text can be stored can vary greatly. In addition to ASCII based files, text is typically stored in processor files, spreadsheets, databases and annotations on more general multimedia objects. With availability and proliferation of GUIs, text fonts the job of storing text is becoming complex allowing special effects(color, shades..).
Graphics – There is great variance in the quality and size of storage (Image file formats) for still images (Bitmap – gif, jpg, bmp) (Vector – svg, pdf, swf, ps). Digitalized images are sequence of pixels that represents a region in the user’s graphical display.
Audio – An increasingly popular datatype (audio file format) being integrated in most of applications is Audio. Its quite space intensive. One minute of sound can take up to 2-3 Mbs of space. Several techniques are used to compress it in suitable format.
Animation – It involves the appearance of motion caused by displaying still images one after another. Often, animation is used for entertainment purposes. In addition to its use for entertainment, animation is considered a form of art. It is often displayed and celebrated in film festivals throughout the world. Also used for educational purposes.
Video – One on the most space consuming multimedia data type is digitalized video. The digitalized videos are stored as sequence of frames. Depending upon its resolution and size a single frame can consume upto 1 MB. Also to have realistic video playback, the transmission, compression, and decompression of digitalized require continuous transfer rate.
Graphic Graphics (Objects) – These consists of special data structures used to define 2D & 3D shapes through which we can define multimedia objects. These includes various formats used by image, video editing applications.
Multimedia tools and Applications
A Multimedia Application is an application which uses a multiple media sources e.g. text, graphics, images, sound/audio, animation and/or video. Multimedia conference covers the selected tools applied in multimedia systems and key multimedia applications. It comprises of Audio, video processing, Virtual reality and 3-D imaging, Virtual reality and 3-D imaging, Multimedia and Artificial Intelligence.
Multimedia Applications is the creation of exciting and innovative multimedia systems that communicate information customized to the user in a non-linear interactive format.
