Multimedia Basics Essay

Application of multimedia system systemMultimedia finds its application in various athletic fields including, advertisements, art, education, fun, engineering, medicine, mathematics, business, and scientific research applications. A few application areas of multimedia are listed belowEntertainment and lovely ArtsIn addition, multimedia is heavily apply in the entertainment industry, especially to develop special effects in movies and animations. Multimedia games are a popular pastime and are software program programs available any as CD-ROMs or online. Some television receiver games also use multimedia features. Multimedia applications that allow substance abusers to actively participate instead of just session by as passive recipients of selective information are called Interactive Multimedia. teaching methodIn Education, multimedia is used to produce computer-based training courses (popularly called CBTs) and reference books analogous encyclopedia. A CBT lets the user go through a series of presentations, school text about a particular topic, and associated illustrations in various information formats. Edutainment is an cosy term used to describe combining education with entertainment, especially multimedia entertainment.EngineeringSoftware engineers may use multimedia in computing machine Simulations for anything from entertainment to training much(prenominal) as military or industrial training. Multimedia for software interfaces are often done as collaboration between creative professionals and software engineers.IndustryIn the Industrial sector, multimedia is used as a way to help present information to shareholders, superiors and coworkers. Multimedia is also helpful for providing employee training, advertising and selling products all everywhere the world via virtually unlimited web-based technologies.Mathematical and Scientific ResearchIn Mathematical and Scientific Research, multimedia is mainly used for modeling and simulation. For example, a scientist can look at a molecular model of a particular substance and manage it to arrive at a newly substance. Representative research can be found in journals such as the Journal of Multimedia.MedicineIn Medicine, doctors can get apt by looking at a virtual surgery or they can simulate how the human body is affected by diseases strewing by viruses and bacteria and then develop techniques to prevent it.Multimedia clay ArchitectureMultimedia encompasses a large variety of technologies and integration of treble computer architectures interacting in real time. All of these multimedia capabilities must integrate with the hackneyed user interfaces such as Microsoft Windows. The following figure describes the architecture of a multimedia workstation environment.From the above figure the left side is very correspondent to non-multimedia systems. Right side shows the architecture of multimedia supporting system. Multimedia Extensions is used to enhance the speed of proce ss. The add-on multimedia devices and peripherals include scanner, video camera, VCR, and telephone set equipment along with their associated device controllers. For each of these special devices, a special software device driver is makeed to provide the interface from the application to the device. The lifelike user interface designed primarily for windows managed by applications at furbish up resolution require control to extensions to support applications such as full-motion video or remote desktop.Evolving Technologies for Multimedia SystemsMultimedia applications use a fare of technologies generated for both commercial business application as well as the video game industry. Let us review some of these technologies in this section.Hypermedia DocumentHypermedia documents are documents which have text, embedded or linked multimedia objects such as image, audio, hologram, or full-motion video.HypertextHypertext implements the organization of non-sequential of info by natural association of information. Hypertext systems allow authors to link information unitedly create information paths through a large volume of connect text in documents. It also allows annotating existing text, and appending notes. It allows turbulent and blue-blooded searching and reading of selected excerpts.Hyper name and addressMultimedia stimulated the development of general-purpose speech interfaces. Speech synthesis and speech recognition are fundamental urgency for hyperspeech systems. Speech recognition is nothing but converting the analog speech into a computer action and into ASCII text. Speech-recognition systems cannot segment a stream of sounds without breaks into meaningful units. The user must speak in a stilted fashion. He should shuffling sure to interpose silence between each word.3D and Holography three-d technologies are concerned with two areas pointing devices and displays. 3-D pointing devices are essential to manipulate object in a 3-D display system. 3- D displays are achieved using holography techniques.Digital Signal treatDigital Signal Processing is used in applications such as digital servos in stark disk drives, and fax/modems. DSP technology is used in Digital radio receiver communications, such as personal communication networks (pens), wireless local area networks and digital cordless phones.DSP Architectures and ApplicationsA typical DSP operating system architecture would contain the following subsystems Memory Management DSP architectures provide dynamic parceling of arrays from multiple segments, including RAM, SRAM and DRAM. Hardware-Interrupt handling A DSP operating system must be designed to minimize hardware interrupt latency to ensure fast response to real time events for applications, such as servo systems. Multitasking DSPs needreal-time kernels that provide pre-emptive multitasking and user-defined and dynamic task prioritization.
