Videoconferencing used to be a relatively low-resolution 4:3 aspect-ratio affair, but in recent years it has been transformed by high-definition (HD) 16:9 video, displayed on large screens in custom-built suites. To reflect this enhanced, immersive, experience, the term 'telepresence' has been adopted. The exemplar of telepresence is <a href="http://www.cisco.com/en/US/netsol/ns669/networking_solutions_solution_segment_home.html">Cisco's eponymous product</a>, which is notoriously expensive — it'll set you back around £150,000 for a dedicated suite, with serious service/bandwidth charges on top of that. HP also plays in this high-end market with its <a href="http://h71028.www7.hp.com/enterprise/cache/570006-0-0-0-121.html">Halo</a> product, along with the likes of <a href="http://www.tandberg.com/">Tandberg</a>, <a href="http://www.teliris.com/">Teliris</a> and <a href="http://www.polycom.com/emea/en/home/index.html#">Polycom</a>.
