Digital speech coding is used in a wide variety of every day applications that the ordinary person takes for granted, such as network wireline and cellular telephony and telephone answering machines. This article reviews some of the most currently used methods of speech coding. This includes reviewing the basic attributes of these coders, the methods used for coding and some of the most important speech coding standards. It also reviews the methods used to realize digital speech coders, especially those for implementing these coders in a cost effective manner.

This chapter gives description and comparison of video coding standards currently used in bandwidth limited mobile communications emphasizing at the same time the importance of coding efficiency and robustness, particularly for video applications. Due to its exceptional efficiency and performance a number of mobile service operators recognized and embraced relatively new H.264/AVC compression method. Utilization of this efficient compression method in the bandwidth limited and distortion prone mobile environment enables and provides transport of high quality video on low data rates. In order to demonstrate these abilities a comparison of H.264/AVC relative to MPEG-4 SP and H.263 method is presented. Comparison is performed using objective video quality assessment methods accompanied with description of different issues related to video quality measurement and its implication on coding process. Finally, comparison showed and confirmed great efficiency and performance possibilities, which will make H.264/AVC the ubiquitous coding technique of multimedia world in time to come.
