Multimedia

Guide to find multimedia must begin with a definition or understanding of multimedia. In the electronics industry, multimedia is a combination of computer and video (Rosch, 1996) or multimedia in general is a combination of three elements namely, sound, pictures and text (Mc Cormick, 1996) or multimedia is a combination of at least two media input or output of data, this media can be either an audio (voice, music), animation, video, text, graphics and images (Turban et al, 2002) or multimedia is a tool that creates a dynamic and interactive presentation that combines text, graphics, animation, audio and image video (Robin and Linda, 2001).

Another definition of multimedia is by placing it in context, as is done by Hoftsteter (2001), multimedia is the use of computers to create and combine text, graphics, audio, video and animation by combining links and tools that enable users to navigate, interact, be creative and communicate. In this definition contained four important components of multimedia. First, there must be a computer that coordinates what is seen and heard that interact with us. Second, there must be a link that connects us with information. Third, there should be a navigation tool that guides us, surf the information network connected to each other. Fourth, multimedia provides a place for us to collect, process and communicate information and ideas of our own. If one component is missing, the multimedia in the broad sense rather than its name. For example if there is no computer to interact then it's called mixed-media, not multimedia. If no link that presents a structure and dimension, hence its name bookshelves, not multimedia. If no navigation that allows us to choose the course of an action movie then it's called, not multimedia. Likewise, if we do not have the space to be creative and contribute ideas itself, hence its name television, not multimedia. From the above definition, then there is an online multimedia (internet) and offline multimedia (traditional). MultimediaUnsur elements - elements in multimedia support, among others: 1. TeksBentuk easiest multimedia data is stored and controlled text. Text is closest to us and the most we see. Text can form a word, letter or narrative in multimedia presents our language. Text needs depends on the use of multimedia applications. In general there are four types of text that is printed text, scanned text, electronic text and hyperteks.2. GrafikAlasan to use images in presentations or multimedia publication is that more attention and to reduce boredom compared with the text. Images can summarize and present complex data in new ways and more useful. It is often said that a picture is able to present a thousand words. But this applies only when we used to display the desired picture when we need it. Multimedia petrified we do this, when the graphic image becomes an object of a link. Graphics often appears as a backdrop (background) of a text to present a framework that sweeten the text. In general there are five kinds of pictures or graphics is vector image (vector image), image bitmap (bitmap image), clip art, digitized picture and hyperpicture.3. SoundBunyi or sound or sound in multimedia computers, especially in the field of business applications and games are very useful. Multimedia computer with no sound just called unimedia, not multimedia. Sound or sound can we add in multimedia production through sound, music and sound effects. Just as in the graph, we can buy the collection in addition to creating his own sound. Several types of commonly used sound objects in a multimedia production that is the audio waveform format, compact disc audio, MIDI sound track and mp3.4. VideoVideo is recording live images or moving images of each sequence. There are two kinds of video ie video analog and digital video. Analog video signal is formed from a series of electrical (analog waves) recorded by cameras and broadcast over the airwaves. While digital video is formed of a series of digital signals in the form that describes the point as a series of minimum or maximum value, minimum value is 0 and the maximum mean value. There are three main components that make up the digital video frame rate, frame size and data type. The frame rate describes how many times the image appears every second frame, while the frame size is the actual physical size of each frame image and data type determines how much color difference that can arise when bersamaan.5. AnimasiDalam multimedia, animation is the use of computers to create motion on the screen. There are nine kinds of animation cell animation, frame animation, animated sprites, animated trajectories, spline animation, vector animation, character animation, animation, computational and morphing.
