Abstract: A system may overlay real-time data and other data (e.g., measurement data, sensor data, etc.) over image data during a communication session. For example, the system may perform media processing on image data being sent between devices in order to overlay the real-time data and other information received from input devices (e.g., sensors, diagnostic devices, connected health devices, etc.) on top of image data during the communication session. For example, a patient may video conference with a doctor and real-time diagnostic information from a device attached to the patient (e.g., wearable device or other input device) may be overlaid on the video to display relevant information during the video conference.
