In today’s Internet, the primary transport mechanism for video streams is the UDP protocol, either congestion sensitive or
not. In this paper, we propose a mechanism that supports the high quality streaming and adaptation of stored video across
best-effort networks using the TCP transport protocol. Our proposed approach has a number of useful features. First, it is
built on top of TCP, which effectively separates the adaptation and streaming from the transport protocol. This makes the
question of TCP-friendliness, the behavioral property of a flow that allows fair-sharing of bandwidth with other flows, much
easier to answer. Second, it does not rely on any special handling or support from the network itself, although any additional
support from the network itself will indirectly help increase the video quality. Finally, we show through experimentation
that this approach provides a viable alternative for streaming media across best-effort networks.
