1. A system for transmitting still images and a video feed to a remote location, the system comprising:

  • an aircraft including one or more digital video cameras to capture still images and video frames of an object;

    a video encoder coupled to the one or more cameras to provide a video output including video packets of the captured video frames;

    a file server coupled to the camera to provide a still image output including image data packets of the captured still images;

    a multiplexer coupled to the video output and the still image output, the multiplexer having an image file input operable to receive the still image output of the file server and a video stream input operable to receive the video output of the video encoder,wherein the multiplexer is operable to produce a data transmission comprising blocks of a still image and a header field defining the still image from the image data packets, data for the video stream and data fields from the video packets, the data transmission comprising a transmission of still images during the transmission of a video stream without interruption of the video stream,wherein the multiplexer is configured to receive input defining a ratio of video packets to image data packets to be combined in the data transmission, wherein the defined ratio is selectable as a function of available bandwidth allocated to the aircraft, and wherein the defined ratio is usable to control transmission priority of the still image output with respect to the video output; and

    a transmitter to send the data transmission to the remote location.
