Main System Requirements
Multiple inputs – number of input streams will
not be limited.Late integration – integration of more input streams will not require complete re-processing.
User extensions – support for user-defined plugins and extensions through a user-friendly API.
Interface – GUI should be designed to include
real-time processing information.

What is
is an advanced offline multiplexer that integrates N data streams into one stream that is closest to the original
uses generic and dynamic configurations, including user-friendly API for custom correction algorithms. It supports post integration of late inputs, dynamic utilization of self-written algorithms and provides valuable statistical information.
