      networks. It allows physically separated users to work in a collaborative
      fashion with documents and applications. It is however not a cooperative
      application but a system level service exporting the functionality of
      applications to many workstations.},

   abstract = {Recent technology advances have made computer-based multimedia cooperation
      among distributed users feasible. Joint-Viewing (JV) is one such proposed
      cooperation concept. Correct interaction in it requires synchronization at
      various levels. In this paper we focus on synchronization aspects on the data
      stream level. We present several JV scenarios and state for each of these
      requirements concerning interstream synchronization. Then we introduce basic
      abstractions of a synchronisazion scheme which is powerful enough to model a
      variety of JV configurations with their various synchronization needs. The
      presented scheme is based on the notion of a referencing system which consists
      of a set of logical clocks each defining a different time zone in the
      referencing system. Logical clocks provide timing information for input and
      output devices which are used to produce and consume data in a synchronized
      fashion.},
