The Problem15 June 2011

What can we do?15 June 2011

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.
