By Nikil Jayant

Broadband final Mile: entry applied sciences for Multimedia Communications presents in-depth remedies of entry applied sciences and the functions that depend on them or aid them. It examines thoughts and improvements alongside a number of dimensions in entry, with the overarching target of making sure that the final mile isn't the susceptible hyperlink within the broadband chain. Written through specialists from the educational and advertisement segments of the sector, the book's self-contained sections handle themes regarding the disciplines of communications, networking, computing, and sign processing.The middle of this therapy comprises modern experiences of broadband pipes within the periods of copper, cable, fiber, instant, and satellite tv for pc. It emphasizes the coexistence of those periods inside of a community, the significance of optical communications for unheard of bandwidth, and the flexibleness and mobility supplied through wireless.The ebook additionally comprises standpoint at the more and more vital subject of community administration, offering insights which are real whatever the nature of the pipe. The textual content concludes with a dialogue of newly rising purposes and broadband services.This e-book bargains an all-in-one therapy of the actual pipes and community architectures that make wealthy and more and more custom-made functions attainable. It serves as a useful source for researchers and practitioners operating within the more and more pervasive box of broadband.

Sample text

Typically, text and electronic documents are compressed in a lossless manner and media are typically compressed in a lossy manner. Media are compressed in a lossy manner for two reasons: (1) lossy compression can enable much higher compression rates; and (2) generally one does not require a perfect reconstruction of the original media signal, so it is sufficient (and practically more beneficial) to have a reconstructed signal perceptually similar (but not necessarily bitwise identical) to the original.

Because of the time-varying or nonstationary characteristics of typical media signals, to achieve a constant quality across all time requires a variable bit rate across time. On the other hand, to achieve a constant bit rate across time leads to a time-varying quality. 4. 2 by a brief review of the most popular and practically important compression standards for each of these different types of media. Speech Compression. 2 kHz and commercial digital telephony uses a 64-kbps format called PCM. In some instances, the speech is compressed, with very little loss of quality, to 32 Copyright © 2005 by Taylor & Francis kbps by using adaptive differential pulse code modulation (ADPCM) in which the quantized information is an appropriate differential signal rather than the original speech sample.

28 An important note is that lossless compression of natural images typically achieves a compression ratio of less than 2:1; non-natural images such as computer graphics or text can achieve much higher compression ratios. The newest image compression standard, JPEG-2000, was designed to provide improved compression performance and new functionalities compared to the original JPEG standard. Specifically, JPEG-2000 was designed to provide high compression performance; various forms of scalability, including bit rate scalability, spatial resolution scalability, and SNR (amplitude resolution or quality) scalability; and support high bit rates up to lossless compression, large bit depths per pixel, many color components (for multispectral imaging), random access, and error resilience.
