Multimedia system architecture in computer graphics

Multimedia computing is a logical next step by which computing technology will become ever more useful and ubiquitous in our everyday lives. From the perspective of technical challenges, multimedia affects nearly every aspect of computer hardware and software. The long-heralded marriage of computing, communications, and information services is now being consummated, and is manifesting itself in literally dozens of new alliances between companies ranging from semiconductors to cable TV, from newspapers and telephone companies to computer hardware and software. • Book Title : Multimedia • Book Subtitle : System Architectures and Applications • Editors : José L.

Multimedia Systems Architecture Multimedia encompasses a large variety of technologies and integration of multiple architectures interacting in real time. All of these multimedia capabilities must integrate with the standard user interfaces such as Microsoft Windows. The following figure describes the architecture of a multimedia workstation environment. In this diagram. The right side shows the new architectural entities required for supporting multimedia applications. For each special devices such as scanners, video cameras, VCRs and sound equipment-, a software device driver is need to provide the interface from an application to the device. The GUI require control extensions to support applications such as full motion video High Resolution Graphics Display The various graphics standards such as MCA, GGA and XGA have demonstrated the increasing demands for higher resolutions for GUls. Combined graphics and imaging applications require functionality at three levels. They are provided by three classes of single-monitor architecture. (i) VGA mixing: In VGA mixing, the image acquisition memory serves as the display source memory, thereby fixing its position and size on screen: (ii) VGA mixing with scaling: Use of scalar ICs allows sizing and positioning of images in pre-defined windows. Resizing the window causes the things to be retrieved again. (iii) Dual-buffered VGA/Mixing/Scaling: Double buffer schemes maintain the original images in a decompression buffer and the resi...

The book presents comprehensive coverage of Computer Graphics and Multimedia concepts in a simple, lucid and systematic way. It uses C programming language to implement various algorithms explained in the book. The book is divided into two parts. The first part focuses on a wide range of exciting topics such as illumination and colour models, shading algorithms, line, curves, circle and ellipse drawing algorithms, polygon filling, 2D and 3D transformations, windowing and clipping, 3D object representation, 3D viewing, viewing pipeline, and visible surface detection algorithms. The second part focuses on multimedia basics, multimedia applications, multimedia system architecture, evolving technologies for multimedia, defining objects for multimedia systems, multimedia data interface standards, multimedia databases, compression and decompression, data and file format standards, multimedia I/O technologies, digital voice and audio, video image and animation, full-motion video and storage and retrieval technologies. It also describes multimedia authoring and user interface, Hypermedia messaging, mobile messaging, integrated multimedia message standards, integrated document management and distributed multimedia systems.

Overview A Graphics Processor Unit (GPU) is mostly known for the hardware device used when running applications that weigh heavy on graphics, i.e. 3D modeling software or VDI infrastructures. In the consumer market, a GPU is mostly used to accelerate gaming graphics. Today, GPGPU’s (General Purpose GPU) are the choice of hardware to accelerate computational workloads in modern High Performance Computing (HPC) landscapes. HPC in itself is the platform serving workloadslike Machine Learning (ML), Deep Learning (DL), and Artificial Intelligence (AI). Using a GPGPU is not only about ML computations that require image recognition anymore. Calculations on tabular data is also a common exercise in i.e. healthcare, insurance and financial industry verticals. But why do we need a GPU for these types of all these workloads? This blogpost will go into the GPU architecture and why they are a good fit for HPC workloads running on vSphere ESXi. Latency vs Throughput Let’s first take a look at the main differences between a Central Processing Unit (CPU) and a GPU. A common CPU is optimized to be as quick as possible to finish a task at a as low as possible latency, while keeping the ability to quickly switch between operations. It’s nature is all about processing tasks in a serialized way. A GPU is all about throughput optimization, allowing to push as many as possible tasks through is internals at once. It does so by being able to parallel process a task. The following exemplary diagram...

In this chapter, we will discuss how the Computer Multimedia works. If a system presents, some information through more than two media, it is known as multimedia. For example, TV presents audio and video; book presents text, image, and graphs, computer, etc. The information presented through multimedia has better quality and capability, as it can be understood easily. The advanced computer system is a great example of modern multimedia. Literal Meaning of Multimedia In this section, we will understand the literal meaning of multimedia. • Multi− it means more than one • Medium− it is singular and it means intermediary or mean • Media− it is plural and it means conveying the information Likewise, Multimedia is the field of Computer Science that integrates different forms of information and represents in the form of audio, video, and animation along with the traditional media, i.e., text, graphics/drawings, images, etc. Multimedia Computer System Multimedia computer system has high capacity to integrate different media including text, image, graphics, audio, and video. The multimedia computer system stores, represents, processes, manipulates, and makes available to users. Significant Features of Multimedia Computer System Following are the major features multimedia computer system − • Its Central Processing Unit (CPU) is very fast, as it needs to process large amount of data. • It has huge storage capacity. • It has huge memory power that helps in running heavy data programs....
