  Multiview video with interactive and smooth view switching at the receiver is
a challenging application with several issues in terms of effective use of
storage and bandwidth resources, reactivity of the system, quality of the
viewing experience and system complexity. The classical decoding system for
generating virtual views first projects a reference or encoded frame to a given
viewpoint and then fills in the holes due to potential occlusions. This last
step still constitutes a complex operation with specific software or hardware
at the receiver and requires a certain quantity of information from the
neighboring frames for insuring consistency between the virtual images. In this
work we propose a new approach that shifts most of the burden due to
interactivity from the decoder to the encoder, by anticipating the navigation
of the decoder and sending auxiliary information that guarantees temporal and
interview consistency. This leads to an additional cost in terms of
transmission rate and storage, which we minimize by using optimization
techniques based on the user behavior modeling. We show by experiments that the
proposed system represents a valid solution for interactive multiview systems
with classical decoders.
