Abrégé
(EN) A method for simulating an interactive movie on a computer display from a sequence of digital frames, as data is received on-line, comprises the steps of:
```joining the digital frames together to form a large digital image; encoding the large digital image to generate encoded image data; storing the encoded image data;
```transmitting the encoded image data to a client computer upon request;
```decoding the encoded image data to generate a reconstructed large digital image 58; and
```displaying moving window views of the reconstructed large digital image in a fixed display window 70, in response to keyboard presses and mouse clicks by a user, to exhibit the same effect as if advancing forward and backward through the digital frames, in order to simulate interactive motion on the client computer display device.
