<p>A method and apparatus are provided for blending analog and digital portions of a composite digital audio broadcast signal by using look ahead metrics computed from previously received audio frames to guide the blending process and prevent unnecessary blending back and forth between analog and digital if the look ahead metrics indicate that future digital signal quality is degraded or impaired. A method and apparatus are provided for blending analog and digital portions of a composite digital audio broadcast signal by using look ahead metrics computed from previously received audio frames to guide the blending process and prevent unnecessary blending back and forth between analog and digital if the look ahead metrics indicate that future digital signal quality is degraded or impaired. A method of delivery of medical data via a trusted end-to-end communication link. The method comprises obtaining a measurement of a parameter of a human being by a first sensor, obtaining a biometric from the human being by a second sensor, receiving input from the first and second sensors by a secure application executing in a trusted security zone of a processor, whereby access to the input from the first and second sensors by applications executing in a normal partition of the processor is blocked, wherein the input from the first and second sensors comprises the measurement of the parameter and the biometric, and transmitting a message based on the input from the first and second sensors via a trusted end-to-end communication link to a medical data server, wherein an application that receives the message executes in a trusted security zone of the server.</p> |
