title: Guidelines for multipoint videoconferencing using low-cost, PC-based equipment.
abstract: We have compiled a set of guidelines for effective multipoint videoconferencing carried out with low-cost, PC-based systems. The guidelines are based on experience gained during multipoint videoconferences in epidemiology and orthopaedics/radiology. Joint data inspection and manipulation were carried out by application sharing between the PCs. The guidelines are categorized by the time of their application and also by their content. For effective multipoint videoconferences, preparation of the agenda and of digital documents is mandatory. The prevention of echo effects and half-duplex audio connections are of special importance. A protocol to optimize the order of speakers increases the efficient use of conference time. The guidelines worked well when used in a multisite research project and addressed the most important weak points of multipoint videoconferences using low-cost equipment.
