What is Multiple Bit Rate Video

Chapter 46
Encyclopedia of Internet Technologies and Applications
The support of multiple encoded video streams within one media stream. By using multiple bit rate video in an encoder, you can create media-based content that has a variety of video streams at variable bandwidths ranging from, for example, 28.8 Kbps through 300 Kbps, as well as a separate audio stream. After receiving this multiple encoded stream, the server determines which bandwidth to stream based on the network bandwidth available. Multiple bit rate video is not supported on generic HTTP servers.

Abstract
Mobile communications is a continually growing sector in industry and a wide variety of visual services such as video-on-demand have been created which are limited by low-bandwidth network infrastructures. The distinction between mobile phones and personal device assistants (PDA’s) has already become blurred with pervasive computing being the term coined to describe the tendency to integrate computing and communication into everyday life. New technologies for connecting devices like wireless communication and high bandwidth networks make the network connections even more heterogeneous. Additionally, the network topology is no longer static, due to the increasing mobility of users. Ubiquitous computing is a term often associated with this type of networking.
