“…Furthermore, once the technology infrastructure is in place, it can support numerous applications, such as distance learning, real-time clinical consultation, and live case demonstrations. 7,10 We recognize a number of potential limitations of the use of advanced networks, such as Internet2 and APAN, and the DVTS. Namely, the robust technology has intensive bandwidth requirements.…”

“…Early examples within the United States include transmission of video of live surgery over Internet2 (Damore et al, 1999). Examples in Asia include remote surgical presentations at conferences and special events between Korea, Japan, Singapore, the United States, and Australia (Carati, et al, 2006;Shimizu et al, 2006;Singapore National Eye Centre, 2006) and work between Korea and the United States presenting cancer surgery (Dr. P. Kim, personal communication, 2006). A recent article summarizes the activities of 100 such presentations (Shimizu et al, 2009).…”

We present a pilot trial of a broadband telehealth system for tertiary outpatient consultations and use it as a case study to explore issues that arise in designing and evaluating broadband telehealth at a tertiary level of health care. The trial used outpatient consultations for pediatric surgical patients; these consultations involve high levels of interpersonal communications, multiple participants, and the need to share interactive access to large patient data sets. We used a human-centered evaluation approach applied at the level of the health care application (in the hospital setting using actual clinical consultations). The results from the case study indicate that this is the appropriate evaluation approach for early stage trials rather than the traditional randomized controlled trials. The different groups of participants (specialists, patients and parents, supporting clinicians) had different perspectives on the telehealth consultations and different criteria for success and future telehealth evaluations need to take these multiple points of view into account.

“…Using the 60-GHz band as detailed by the WirelessHD specification, SiBEAM's chipset was designed to support uncompressed HD video transmission [28]. Hence, uncompressed video transmission may be used both for home networking [26] and for other high-quality applications, such as lossless medical video communications [35], [36].…”

Low-complexity uncompressed video transmission meets the requirements of home networking and quality/ delay-sensitive medical applications. Hence, it has attracted research attention in recent years. The redundancy inherent in the uncompressed video signals may be exploited by joint source-channel decoding to improve the attainable error resilience. Hence, in this treatise, we study the application of iterative joint source-channel decoding aided uncompressed video transmission, where correlation inherent in the video signals is modeled by a first-order Markov process. First, we propose a spatiotemporal joint source-channel decoding system using a recursive systematic convolutional codec, where both the horizontal and vertical intraframe correlations, as well as the interframe correlations, are exploited by the receiver, hence relying on 3-D information exchange. This scheme may be combined with arbitrary channel codecs. Then, we analyze the three-stage decoder's convergence behavior using 3-D extrinsic information transfer (EXIT) charts. Finally, we benchmark the attainable system performance against a couple of video communication systems, including our previously proposed 2-D scheme, where only intraframe correlations were exploited without invoking a channel codec. Our simulation results show that substantial E b /N 0 improvements are attainable by the proposed technique.Index Terms-Iterative detection, joint source and channel coding, spatio-temporal video processing, video telephony, wireless video communication.
