Available in PDF, EPUB and Kindle. Book excerpt: Digital Media: Voice, Video, Images, Quantities and Text The converged network carries all media: voice, video, text and images in packets. An essential first step is digitizing the media, representing it using 1s and 0s, to be carried in said packets. We’ll first understand analog vs. digital, how voice is digitized and reconstructed, the G.711 64 kb/s and AMR codec standards. The same principles apply to images and video in formats like jpg and mp4 video. We’ll make sure you are up to speed on binary and hexadecimal for quantities, and finish with ASCII and unicode for coding keystrokes and emojis.

Download or read book Multimedia Technologies and Applications for the 21st Century written by Borko Furht and published by Springer Science & Business Media. This book was released on 1997-11-30 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multimedia Technologies and Applications for the 21st Century: Visions of World Experts presents contributions from leading researchers and experts describing their current research and their views of the future trends in the field. The book consists of thirteen chapters in five parts. These chapters tackle a number of critical issues in distributed multimedia systems and applications - from VLSI processors that support multimedia and multimedia servers, through multimedia databases and multimedia networks and communications, to merging multimedia applications. Only a few years ago multimedia seemed like a brand new research field and an emerging new industry. Today, at the edge of the 21st century, multimedia research is coming of age, and the multimedia industry has significantly grown with the total market estimated to be about $50 billion. Several years ago it was felt that the digital media revolution had just started; however, the seeds had been sown long before. Fundamental technologies, such as interactive laser disks, video games, and electronic encyclopedias were invented in the 1970s and 80s. They represented the seeds for current `hot' applications, such as digital libraries, video-on-demand, interactive television, and videoconferencing. Another aspect of the digital media revolution is the formation of a new media industry composed of computer, entertainment, communication, and consumer electronics companies. Many industry segments are currently involved in creating new products and services, positioning themselves for the 21st century. They include telephone, cable, and satellite TV companies, communication equipment companies, TV and radio broadcasters, on-line Internet service providers, cable channels, movie studios, record companies, book publishers, CD-ROM title creators, Internet tool vendors, multimedia software tools companies, computer companies, general software tools companies, computer add-on vendors, semiconductor vendors, and consumer electronics vendors. Multimedia Technologies and Applications for the 21st Century: Visions of World Experts should stimulate the curiosity of its readers and inspire new technological breakthroughs in this exciting field. It serves as a valuable reference for system designers, engineers, programmers, and managers who are involved in multimedia systems, the Internet, and their applications. This book can also be used as a textbook for advanced courses on multimedia in engineering curricula.

Download or read book Beyond Quantity written by Andreas Sudmann and published by transcript Verlag. This book was released on 2023-11-30 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do artificial neural networks and other forms of artificial intelligence interfere with methods and practices in the sciences? Which interdisciplinary epistemological challenges arise when we think about the use of AI beyond its dependency on big data? Not only the natural sciences, but also the social sciences and the humanities seem to be increasingly affected by current approaches of subsymbolic AI, which master problems of quality (fuzziness, uncertainty) in a hitherto unknown way. But what are the conditions, implications, and effects of these (potential) epistemic transformations and how must research on AI be configured to address them adequately?
