Abstract
The invention relates to a video coding method based on an adaptive frame/field encoding mode. In order to avoid an impairment of the image quality and of the compression efficiency when a video sequence comprises a lot of motion or on the contrary quasi-motionless images, an improved real time double pass encoding scheme is proposed: during the first pass, no video stream is generated, but statistical results are computed and then provided to the second pass in order to optimize during said second pass the bit rate allocation and the buffer management. This improved double pass encoding method leads to an increase of the compression efficiency of about 10%.
