METHOD FOR SWITCHING A FIRST DIGITAL AUDIO-VISUAL PROGRAMME VIDEO COMPONENT(S) ON A SECOND DIGITAL AUDIO-VISUAL PROGRAMME VIDEO COMPONENT(S)

摘要

The invention concerns a method for switching a first digital audio-visual programme video component(s) on a second digital audio-visual programme video component(s), which consists in switching on the beginning of the first set of images comprising an Intra-coded picture of the second programme video component encountered after the switching command, and in the transmission order of images, substituting each bidirectionally predictive-coded picture of said first set of images referring to the set of images pertaining to the set of images preceding it before switching, with a bidirectionally predictive-coded picture whereof the video coding is produced independently of the substituted image content and of the contents of the images to which it refers.
