ABSTRACT
Video compression enables a number of applications by reducing
the required bit rate needed to represent a video sequence, how-
ever the compressed video is much more susceptible to errors such
as bit errors or packet loss. Conventional video compression stan-
dards employ an architecture which we refer to as single-state sys-
tems since they have a prediction loop with a single state (e.g. the
previous decoded frame) which if lost or corrupted can lead to
the loss or severe degradation of all subsequent frames until the
state is reinitialized (the prediction is refreshed). We combat this
problem of incorrect state and error propagation at the decoder by
coding the video into multiple independently decodable streams,
each with its own prediction process and state, such that if one
