ABSTRACT
This paper presents a method for distortion-optimized streaming
of predictively coded video over packet networks with varying de-
lay. In networks with significant delay variations, coded video
frames can arrive late at the decoder and miss their respective dis-
play deadlines. Furthermore, due to predictive coding, a late frame
can also prevent a number of subsequent frames from being dis-
played properly, where the number of affected frames or degree
of distortion depends on the particular coding dependencies of the
late frame. In this paper, we present an optimized video streaming
strategy based on frame reordering for networks with significant
delay variations. This streaming strategy minimizes distortion by
exploiting the fact that different late frames result in different de-
