DEVICE AND METHOD FOR CODING A VIDEO CONTENT IN THE FORM OF A SCALABLE STREAM

摘要

The invention relates to a method of coding a video content in the form of a temporally scalable stream. This content is represented by a first group of interlaced pictures formed by a first field interlaced with a second field and by a second group of progressive pictures, each picture of the second group coinciding with a field of the first group. The method comprises the following steps: - coding the fields of the first group on M temporal levels according to a first predefined coding order, with M an integer strictly greater than 1, such that the second field of a low resolution picture is coded immediately after the first field, and - coding the pictures of the second group of pictures on M temporal levels in a second predefined coding order. According to an essential characteristic of the invention, the second coding order equals the first coding order.
