  In this report, we investigate the data transmission model in which a
sequence of data is broadcasted to a number of receivers. The receivers, which
have different channel capacities, wish to decode the data sequentially at
different rates. Our results are applicable to a wide range of scenarios. For
instance, it can be employed in the broadcast streaming of a video clip through
the internet, so that receivers with different bandwidths can play the video at
different speed. Receivers with greater bandwidths can provide a smooth
playback, while receivers with smaller bandwidths can play the video at a
slower speed, or with short pauses or rebuffering.
