| Description | Three major trends have emerged over the past five years in the way communication, information and entertainment services are provided to consumers: wireless communication, Internet technologies and digital entertainment (audio/video/games). Mobile telephony and Internet technologies have seen tremendous global growth over this period. The scale of the growth and the market needs have resulted in the basic Internet services over mobile telephones. The third major trend, digital entertainment, can be seen in the rapid adoption of digital TV and DVD products. Digital entertainment over the Internet has so far been mainly digital music and, to a lesser extent, streaming video, and online video games. New standards and technologies are making ways for offering applications and services that combine these three trends. A number of technologies have emerged that make possible access to digital multimedia content over wired and wireless networks on a range of devices with varying capabilities such as mobile phones, personal computers and television sets. This universal multimedia access (UMA), enabled by new technologies and standards, poses new challenges and requires new solutions. In this chapter we discuss the technologies, standards, and challenges that define and drive UMA. The main elements of a system providing UMA services are 1) the digital content, 2) the sending terminal, 3) the communication network and 4) the receiving terminal. These seemingly simple and few elements represent a myriad of choices with multiple content formats, video frame rates, bit rates, network choices, protocol choices and receiving terminal capabilities. The operating environment of the service adds a dynamically varying factor that affects the operation of the end-to-end system. The selection of appropriate content formats, networks and terminals and adapting these elements, if and when necessary, to deliver multimedia content is the primary function of UMA services.
