METHOD OF REPRESENTING A NUMBER OF DATA STREAMS IN A COMMON CARRYING DATA STREAM ORGANISED IN FRAMES AND USING IN A FRAME DESCRIPTING INDEX FOR ENABLING THE CONTENTS OF A FRAME TO BE INTERPRETED

摘要

The present invention relates to a method of representing a number of carried streams (1a, 1b, and 1c) in a common carrying data stream (1). A so-called carried data stream is a sequence of mutually related stream elements. The carrying data stream (1) is organised in frames (11, 12) and each frame includes stream elements belonging to one or more different carried data streams. Respective frames (11, 12) include a frame descriptive index (111, 112). Mutually sequential frames can be used to transmit mutually different carried data streams and can include different large amounts of data information. Carried stream elements contained in a frame may be allocated spaces of mutually different size and thus include different amounts of data information. The frame descriptive index (111, 112) enables the contents of respective frames to be interpreted.
