ABSTRACT
Multimedia is now opening new services that support a more convenient and easy to use environment, such as virtual reality for complex systems and for education systems, multiple-view interactive television services and three dimensional home theater. It is not too much to say that the introduction of audio and video into communications worlds, computer worlds and broadcasting worlds formed the beginning of the multimedia. Adding audio and visual environment to the conventional text-base services makes them vivid and attractive for many users. Therefore, realizing a seamless connection and/or fusion among computer, communication and broadcasting worlds, as shown in Fig. 1.1, leads to the possibility of dramatic changes in our lives. The key function, here, is efficient digitization of video and audio, because digital video and audio can be easily fed into the digital computers and digital communication networks. Generation of multimedia world. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315214719/0fb871de-cdc7-4110-bdc0-1b5d88b350ec/content/fig1_1.tif"/>
