Infrastructure

The research infrastructure of the laboratory comprises of a number of hardware and software platforms used for developing and testing new technologies in the area of multimedia networking, featuring:

---

• A Complete end-to-end DVB-T and DVB-S broadcasting platform (mpeg2/mpeg4 encoder, media router, encapsulator, multiplexer, modulator, amplifier, receivers) for broadcast programs and interactive applications





---

• A set of two Autonomous Systems, supporting MPLS/Diffserv for emulating large-scale IP networks



---

• A complete IP Multimedia Subsystem (IMS), fully configurable and customisable, for deploying and testing IMS-compatible applications



---

• An integrated virtualisation environment, based on high-end servers, for testing demanding media applications and running intensive simulations



---

• A high-speed Gigabit Ethernet backplane with VLAN support, owned/fully configurable firewall and aggregate 1GB/s connection to the Internet



---

• A WiMAX system with one Base Station and two Subscriber unit for deploying fixed wireless services



---

• A laboratory-built Network- and Perceived-Quality of Service analysis testbed for measuring and correlating N- and P-QoS for IP-based video applications



---

• A 70 m terrestrial mast for terrestrial broadcasting and wireless networking applications



---

• A satellite ground station for media satellite broadcasting (has operated with HellasSat II and Atlantic Bird III satellites)
