Early next year, AT&T Corp will release an enhancement to its H.320-based MultiPoint Control Unit videoconferencing system, which enables up to four different sites to be seen and heard simultaneously. Originally, the company claimed the enhancement as unique – most existing systems switch between users depending on who is speaking. company has subsequently modified its claim to say that it is the only H.320-based system to feature it, when it was pointed out that Cornell University’s CU-See-Me system, for example, can support up to eight simultaneous windows. The new feature, known as quadrature, is said to use no proprietary technology, enabling integration with other vendors’ H.320-based systems. When it is introduced (no precise date was given) it will ship as standard with the MultiPoint Control Unit, and be available as an upgrade for existing users.
