Abstract

H.265, otherwise known as High Efficiency Video Coding (HEVC), is the most recent of a series of standardized video codecs. This Chapter considers the potential contribution of the new codec to mobile telemedicine. In doing so the structure and components of the codec are analyzed in some detail in relation to its predecessor, H.264. Mobile telemedicine relies on wireless technologies and it is here that H.265 will potentially make its largest contribution, due to the drastic reduction in bandwidth for equivalent video quality that is promised. There are detractions, which will need to be resolved, such as the high encoder complexity and the comparative lack of error-resilience tools for the codec. As the Chapter considers, the former impedes interactive video streaming in emergency healthcare, while the latter will need to be fixed before reliable wireless communication can take place. Progress in mobile telemedicine is to some extent dependent on making available sufficient bandwidth for compressed video transport, and, thus, the later part of the Chapter considers developments in wireless technology that are and will in the near future make video streaming of medical imagery more common and extend to high-definition displays. Wireless technology is also advancing within indoor telecare, including intensive care. Here a combination of short-range telemetry and longer range wireless LANs for video monitoring of patients is coming about, as this Chapter outlines. The Chapter contains a range of largely current references that will enable the topics introduced herein to be followed up in detail.
