An overview of recent end-to-end wireless medical video telemedicine systems using 3G

Abstract

Advances in video compression, network technologies, and computer technologies have contributed to the rapid growth of mobile health (m-health) systems and services. Wide deployment of such systems and services is expected in the near future, and it's foreseen that they will soon be incorporated in daily clinical practice. This study focuses in describing the basic components of an end-to-end wireless medical video telemedicine system, providing a brief overview of the recent advances in the field, while it also highlights future trends in the design of telemedicine systems that are diagnostically driven.

Multimedia content delivery for remote patient monitoring using cognitive radio networks

“…Adaptation to wireless parameters means in that case, diagnosticallyrelevant selection of the source encoding parameters and the error control methods. E-health multimedia systems have been primarily based on 3G wireless networks [5]. However, given the limited upload data rates (up to 384 Kbps), as shown in [6], the associated source encoding parameters were bounded to different medical video resolution sizes/types.…”

A QoS-control framework for medical multimedia data transmission in CRN environment

“…Adaptation to wireless parameters means in that case, diagnostically relevant selection, the source encoding parameters choice and error control methods for addressing transmission errors. E-health multimedia systems have been primarily based on 3G wireless networks [5]. However, given the limited upload data rates supported by these channels (up to 384 kps), as shown in [6], the associated source encoding parameters were bounded to different medical video resolution sizes/types.…”

Performance and Analysis of Video Streaming of Signals in Wireless Network Transmission

“…MAC layer provides many features that is of QoS [5], [6] with different prioritization classes, scheduling upper link and downward link with efficient mobility management and security.…”

“…Diagnostically driven systems rely on the use of diagnostic Regions Of Interest (ROI) [4]- [6] clinical video quality assessment methods are used for communicating the medical video to the medical expert [5], [8]. In terms of the wireless infrastructure, the mobile health video systems are based on 3G wireless networks [3], [5] which have a limited upload data rates of channels that are supported (upto 384kbps) associated with encoding parameters bounded to the CIF resolution video size.…”
