A tool designed to perform quality assurance on IPTV encoded assets is presented. The tool works on stored MPEG-2 transport stream files and combines a powerful graphical-user-interface with automatic no-reference detectors to handle video quality, audio and field-ordering issues. The tool provides automatic quality assurance of assets before they are made available for streaming and replaces the...
Core networks of the future will have a translucent and eventually transparent optical structure. Ultra-high-speed end-to-end connectivity with high quality of service and high reliability will be realized through the exploitation of optimized protocols and lightpath routing algorithms. These algorithms will complement a flexible control and management plane integrated in the proposed solution. Physical...
Reconfigurable transparent networks are now a reality in the core layer thanks to the implementation of innovative transmission and wavelength routing sub-systems. Transparency on a large scale opens up new perspectives in terms of scalability and flexibility. There are numerous promising technologies to achieve that goal but it is likely that only few of them will really prevail in the field. For...
