    Abstract: PROBLEM TO BE SOLVED: To provide a multiplexer that transfers an MPEG multi-program transfer stream to an ATM virtual channel and multiplexes the virtual channel on a virtual path. SOLUTION: A syntax analysis section AS receives a plurality of streams and separates data packets in each stream from service packets. The data packet is directly transferred to a means to generate an output stream, that is, an output stream generator CF and also sent to a processing/controller MP. The processing/controller MP conducts processing and especially updates service information and returns a synthesized output stream. The output stream generator CF generates a single program output stream or a multi-program stream at a frequency band lower than that of the input stream and sends it to a service user. The output stream is obtained by beginning from the packet stored in a temporal storage means that is a memory device ME and the service packet that is processed and set to the virtual ATM channel.

    Abstract: The capacity of switching elements, for instance 8x8 elements, is expanded, to originate single-stage elements with greater capacity (16x16 or 32x32), by arranging an even plurality of said elements in an output sub-stage (10, 11) and by placing upstream of said output sub-stage at least a first input sub-stage (00, 01) comprising a corresponding even plurality of said switching elements. The even and, respectively, the odd outputs of the elements of the input sub-stage (00, 01) are connected in orderly manner to the inputs of the switching elements of the output sub-stage (10, 11). A routing management logic to obtain single-stage elements is also provided within each individual switching element.

    Abstract: A PCM switching element intended to be used in digital telephone exchanges for the making of switching or concentration stages of whatever capacity can be controlled by a commercially available microprocessor and can be made as an integrated circuit. Structures consisting of a plurality of such elements are readily designed owing to the use of a "busy" bit associated with each outgoing PCM channel.

    Abstract: The PCM switching network is based on the use of switching units (UC1a ... UC8c) each equipped with a local controller using a microprocessor (CTR1a ... CTR8c), ancillary circuits for diagnosis (CDTE1 ... CDTU5), ancillary circuits for exchanging messages relating to network control between the local controllers (CRT1a ... CTR8c) and between local controllers and the distributed telephone control units (CTFa ... CTFc), and ancillary circuits (RTBE1 ... RTBU5) providing virtual channels (on the speech channels themselves) for transmission of said messages in a direction opposite to that of speech. Said switching units (UC1a ... UCBc) make it possible to provide self-routing modular PCM switching network structures for distributed-control telephone exchanges.

    Abstract: Apparatus for remultiplexing multi-program audio-video streams transmitted within a switched digital video broadcasting service. The apparatus comprises syntactical analysis and reception means for receiving plural streams, separating data packets in each stream that can be transported directly to means for generating output streams, from service packets that are transmitted to a control unit for processing, in particular for updating service information to reflect the composition of said output streams; means for temporary storage of data packets, separately for each input stream; and output stream generation means for generating and sending service users single program output streams or multi-program streams at a lower band than input streams obtained starting from the packets stored in the temporary storage means and from the service packets processed and entered into virtual ATM channels.
