IEEE Std 1180-1990. IEEE Standard Specifications for the Implementations of 8x8 Inverse Discrete Cosine Transform, specifies the numerical characteristics of the 8x8 inverse discrete cosine transform (IDCT) for use in visual Telephony and similar applications where the 8x8 IDCT results are used in a reconstruction loop. The specifications ensure the compatibility between different implementations of the IDCT.

H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression efficiency, network friendly video representation for interactive (video Telephony) and non-interactive applications (broadcast, streaming, storage, video on demand). H.264/AVC provides gains in compression efficiency of up to 50％ over a wide range of bit rates and video resolutions compared to previous standards. Compared to previous standards, the decoder complexity is about four times that of MPEG-2 and two times that of MPEG-4 Visual Simple Profile. This paper provides an overview of the new tools, features and complexity of H.264/AVC.

H.264/AVC is the current video standardization project of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The main goals of this standardization effort are to develop a simple and straightforward video coding design, with enhanced compression performance, and to provide a 鈥渘etwork-friendly鈥?video representation which addresses 鈥渃onversational鈥?(video Telephony) and 鈥渘on-conversational鈥?(storage, broadcast or streaming) applications.

The past two decades have witnessed the introduction and unprecedented growth of cellular mobile Telephony and wireless communications. Numerous wireless access technologies have been introduced in the mobile communications market. While some have flourished and formed the basis of successful manufacturing and network operator businesses, many have lived only for a short time and disappeared.

Over the past ten years there has been a revolution in the devel- opment and acceptance of mobile products. In that period, cel- lular Telephony and consumer electronics have moved from the realm of science fiction to everyday reality. Much of that revolu- tion is unremarkable – we use wireless, in its broadest sense, for TV remote controls, car keyfobs, travel tickets and credit card transactions every day. At the same time, we have increased the number of mobile devices that we carry around with us. However, in many cases the design and function of these and other static products are still constrained by the wired connections that they use to transfer and share data.

Wireless technologies like GSM, UMTS, LTE, Wireless LAN and Bluetooth have revolutionized the way we communicate by making services like Telephony and Internet access available anytime and from almost anywhere. Today, a great variety of technical publications offer background information about these technologies but they all fall short in one way or another. Books covering these technologies usually describe only one of the systems in detail and are generally too complex as a first introduction. The Internet is also a good source, but the articles one finds are usually too short and super- ficial or only deal with a specific mechanism of one of the systems. For this reason, it was difficult for me to recommend a single publication to students in my telecommunication classes, which I have been teaching in addition to my work in the wireless telecommunication industry. This book aims to change this.
