Abstract (en)
[origin: WO0077960A1] The invention relates to a method and to a device for converting virtually concatenated data streams into contiguously concatenated data streams. The data are transmitted in containers and N containers are combined in one multiframe. The virtually concatenated data streams consist of X partial streams/channels. Every container that is allocated to the same location in the multiframe is identified by evaluating a multiframe indicator of the container. The time-shift of said identified containers of the partial data streams with respect to one another is measured. If such a time-shift is detected, only the leading containers are delayed in such a manner that a time-wise alignment of all containers is achieved. Every channel (KA1, KA2,...) is correlated with a pointer interpreter (PI1, PI2), followed by an flexible memory (ES1, ES2) and a pointer generator (PG1, PG2). The pointer generators are inter-synchronized and every pointer generator is equipped to control the read-out of the flexible memory that pertains to its channel. A channel that is selected as the master channel (KA1) is provided with an overhead inserter (OI1).
