Within the context of the ISO/IEEE 11073 family of standards for device communication@ this standard defines a common framework for making an abstract model of personal health data available in transport-independent transfer syntax required to establish logical connections between systems and to provide presentation capabilities and services needed to perform communication tasks. The protocol is optimized to personal health usage requirements and leverages commonly used methods and tools wherever possible. Purpose This document addresses a need for an openly defined@ independent standard for converting the information profile into an interoperable transmission format so the information can be exchanged to and from personal telehealth devices and compute engines (e.g.@ cell phones@ personal computers@ personal health appliances@ and set top boxes).
