Abstract
A system includes a wrist computer and a portable video camera. The wrist computer acquires physical activity data measured by a sensor device, generates a time marker on the basis of the physical activity data, and transmits the time marker to the portable video camera according to a predefined wireless communication protocol. The portable video camera is configured to record video data, encode the video data into a video data file, and store the received time marker as meta data in the video file.
