ABSTRACT:
The invention relates to a device for coding video frame sequences, comprisingmeans (1) for measuring the spatial activity of the video frames to be coded,means (1) for measuring the temporal activity of the video frames to be coded,means (2) for coding the frames as a frame structure or as a field structure.According to the invention, the means (2) for coding the frames as a frame structure or as a field structure are able to choose the field or frame structure dynamically as a function of the measurements of spatial and temporal activity of the said frame.
