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.

摘要： The invention relates to a method for the dynamic multiplexing of digital streams which are transmitted in the form of stream units in one channel, each of said stream units bearing a stream identifier which can be used to associate same with the corresponding digital stream. The allocation of an identifier to a digital stream is defined by an allocation table and can vary over time, in such a way as to enable dynamic multiplexing. According to the invention, the aforementioned allocation table bears a version number and, in order to indicate that a change in the version of the allocation table applies to a given digital stream, a burst is transmitted with at least one version change stream unit comprising the current identifier of said digital stream, an indicator which can be used to determine if the stream unit is a version change stream unit and the version number becoming applicable to said digital stream.

摘要： The invention concerns a method for switching video component(s) of a first audio-visual digital programme on the video component(s) of a second audio-visual digital programme, characterised in that it consists in switching on the second programme video component after the switching command and after the end of a picture of the first programme and in substituting, in transmission order, for each non-Intra-coded picture of said second programme a picture whereof the coding is produced independently of the substituted picture image data and of the contents of the images whereto it refers until the next Intra-coded picture of said component of said second programme begins.
