Systems and methods for presenting time-varying multimedia content are
described. In one aspect, a lower quality data stream for an initial
portion of the multimedia content is received. The lower quality data
stream is received at a rate faster than a real-time playback rate for
the multimedia content. The lower quality data stream was encoded at a
bit rate below a transmission rate. A higher quality data stream of a
subsequent portion of the multimedia content is received. The higher
quality data stream was encoded at a bit rate that equals the
transmission rate. The initial portion and the subsequent portion of the
multimedia content are presented at the real-time playback rate.
Receiving the initial portion faster than the real-time playback rate
provides for a reduction of latency due to buffering by a desired amount.
