3AHealth’s portfolio involves an array of services pertaining to medical image and video encoding and communication. Over the past decade, significant contributions have been documented for (i) diagnostically-relevant and diagnostically-resilient region-of-interest (ROI) encoding and transmission, (ii) communication medium agnostic adaptive video delivery using multi-objective optimization methods, and (iii) multi-codec multi-resolution encoding for adaptive HTTP streaming applications. Application scenarios extend from remote diagnosis and care, to emergency incident response, as well as assisted-living and medical education.
