Guidelines for multipoint videoconferencing using low-cost, PC-based equipment.

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.

Low-cost ISDN videoconferencing equipment for orthopaedic second opinions.

We validated the application of low-cost ISDN videoconferencing equipment for telemedicine. A telemedicine benchmark was designed and four different office videoconferencing systems were evaluated, all using basic-rate ISDN connections (128 kbit/s). All the low-cost systems showed generally good or acceptable performance for clinical use.

Technical validation of low-cost videoconferencing systems applied in orthopaedic teleconsulting services.

Investigation on the applicability of low-cost videoconferencing (VC) for health care services is becoming a real need. Reduced resources drive the administrators to evaluate inexpensive solutions for telemedicine. Considering this scenario, this work is a preliminary step to validate, from a technical point of view, if low-cost VC systems could be suitable for orthopaedic teleconsulting services.

The Telemedicine benchmark--a general tool to measure and compare the performance of video conferencing equipment in the telemedicine area.

In this paper, we describe the 'Telemedicine Benchmark' (TMB), which is a set of standard procedures, protocols and measurements to test reliability and levels of performance of data exchange in a telemedicine session. We have put special emphasis on medical imaging, i.e.

Practical evaluation of standard-based low-cost video conferencing in telemedicine and epidemiological applications.

The results of the evaluation of use of low-cost video conferencing systems (VCSs) in telemedicine is presented. Applications sharing, a new feature of these systems, recently has allowed high-quality computer-supported collaborative work (CSCW). The video conferencing (VCing) equipment used was Intel ProShare 200 v2.

A study of the application sharing capabilities in telemedicine.

The main aim of this study was to find out if the image format (TIFF or JPEG) influenced the time delay for transferring radiological images by the application sharing tool of a desktop videoconferencing system. The second task of the study was to define a procedure that optimized the time delay to load and remotely visualize the images. The results were achieved by applying a test procedure called 'benchmark protocol'.
