Abstract

Apparatus and method for concurrently converting multiple video and audio formats and sources into different formats. The main elements of the system are: a. A Media Format Matrix (MFM) module, having multiple input and output channels. b. A Communicator module, having various network interfaces. c. A Storage module. The implementation of the system is based on standard networking protocols, used to transfer the data between the internal MFM, Communicator and storage elements. The system platform is built around an internal switched network infrastructure. The management architecture provides a scalable infrastructure for controlling and monitoring single or multiple internal and external system modules, and in addition single, multiple or clusters of systems.
