Multimedia Basics Essay Example for Free

multimedia Basics EssayApplication of MultimediaMultimedia finds its industry in various aras including, advertisements, art, training, diversion, engineering, medicine, mathematics, business, and scientific research applications. A few application atomic number 18as of multimedia system are listed down the stairsEntertainment and Fine ArtsIn addition, multimedia is heavily used in the entertainment industry, specially to develop special effects in movies and animations. Multimedia games are a popular pastime and are software programs available either as CD-ROMs or online. Some video games also use multimedia features. Multimedia applications that allow users to actively participate instead of just sitting by as passive voice recipients of information are called Interactive Multimedia. EducationIn Education, multimedia is used to produce computer-based training courses (popularly called CBTs) and point of reference books like encyclopedia. A CBT lets the user go through a series of presentations, text about a particular topic, and associated illustrations in various information formats. Edutainment is an informal term used to describe combining education with entertainment, especially multimedia entertainment.EngineeringSoftware engineers may use multimedia in Computer Simulations for anything from entertainment to training such as military or industrial training. Multimedia for software interfaces are much 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 stabilising for providing employee training, advertising and selling products all over the world via virtually unlimited web-based technologies.Mathematical and Scientific go through forIn 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 manipulate it to arrive at a new substance. Representative research can be found in journals such as the Journal of Multimedia.MedicineIn Medicine, doctors can get trained by looking at a virtual surgery or they can simulate how the human body is affected by diseases broadcast by viruses and bacteria and then develop techniques to prevent it.Multimedia System ArchitectureMultimedia encompasses a large variety of technologies and integration of multiple architectures interacting in real time. All of these multimedia capabilities must comprise with the standard user interfaces such as Microsoft Windows. The following figure describes the architecture of a multimedia workstation environment.From the supra figure the left side is very similar to non-multimedia systems. Right side shows the architecture of multimedia encouraging system. Multimedia Extensions is used to enhance the speed of process. The add-on multimedia devices and periph erals include scanner, video camera, VCR, and sound equipment along with their associated device controllers. For each of these special devices, a special software device driver is needed to tin the interface from the application to the device. The graphical user interface designed primarily for windows managed by applications at dogged resolution require control to extensions to support applications such as full-motion video or remote desktop.Evolving Technologies for Multimedia SystemsMultimedia applications use a number of technologies generated for both commercial business application as rise as the video game industry. Let us review some of these technologies in this section.Hypermedia archiveHypermedia 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 data by natural association of information. Hypertext systems allow authors to link information together make information paths through a large volume of related text in documents. It also allows note existing text, and appending notes. It allows fast and easy searching and reading of selected excerpts.Hyper deliveryMultimedia stimulated the development of general-purpose speech interfaces. Speech synthesis and speech recognition are fundamental requirement for hyperspeech systems. Speech recognition is nought 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 make sure to interpose silence between each word.3D and HolographyThree-dimensional 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 exploitation holography techniques.Digital Signal Processin gDigital Signal Processing is used in applications such as digital servos in hard disk drives, and fax/modems. DSP technology is used in Digital tuner 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 high-voltage allocation of arrays from multiple segments, including RAM, SRAM and DRAM. Hardware-Interrupt handling A DSP operating system must be designed to lessen 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.
