With the increasing incidence of chronic diseases,
the need to control health care costs and aging
populations, connected health technologies are
becoming increasingly important. The Continua
aggregation manager (AM) will be an essential device
in the connected health system, enabling personal
health devices to log data into a remote electronic
health record (EHR) for family and clinical review.
The AM can take the form of a cell phone, a personal
computer or a dedicated device.
This paper presents three different system
solutions for an AM.These include a high-performance
digital visual interface (DVI) AM (comprising hardware-
accelerated, high-definition [HD] audio/visual [AV]
codecs and a 3-D accelerated user interface [UI]), a
reduced-cost DVI AM (comprising software-based,
standard-definition [SD] AV codecs) and a low-power
AM (supporting software-based audio codecs).
Aggregation managers for the connected health system
The Continua Health Alliance comprises a group of health device original equipment manufacturers (OEMs), service providers and silicon vendors working to provide interoperability guidelines for personal health devices and aggregation managers (AMs).

OEMs currently use a combination of Ethernet, Wi-Fi and cellular interfaces, such as GSM for the AM wide area network (WAN) interface. To be a Continua Certified AM, the device must integrate at least one PAN or low-power LAN interface and a WAN or Internet protocol interface. Because many vendors wish to be interoperable with as many devices as possible, multiple low-power LAN/PAN and WAN interfaces are often integrated.
A Continua AM can take on various form factors. In some cases, this might be a PC or mobile phone. In other cases, it might be a media device connecting to existing or integrated displays. In low-power form factors, the AM can also be a low-power, wearable device. Because many vendors choose to implement both media-centric devices and low-power wearable devices, this white paper presents media-centric AM and low-power AM preintegrated designs.
