Redundancy


The Polistream subtitle transmission system has been designed to cater for a range of redundancy strategies.

Given the variation in system configurations and sizes of installations that Polistream can support there can never be a single redundancy scheme that will suit all cases, therefore here at Screen we use our experience and expertise to develop a strategy to suit your specific needs.

There are two areas which need to be considered, physical I/O redundancy and software component redundancy. In any system there will be a number of physical signal connections and there needs to be a scheme to handle the failure of any one of these.

Polistream's flexible redundancy strategy allows different schemes to be used for various parts of the system. N+N redundancy may be most suitable for either low cost inputs or mission critical sections while N+1 redundancy is best for high value keyers and inserters.


The redundancy options available are:
