摘要： In a system for switching high-capacity and variable length packets from m input ports to n output ports, k Banyan networks are connected into a ring by means of at least n parallel lines, said input ports are connected to inputs of said Banyan networks in a dispersed manner by means of m input modules, misroute tag check parts are connected to outputs of said Banyan networks as well as to inputs of n output modules whose outputs are connected to said output ports. Each of plural unit switches constituting a Banyan network is constructed such that when an input packet cannot be sent to a desired output, the relevant packet is outputted to a non-occupied output of the relevant Banyan network. When the misroute tag check part finds that the misroute tag is set, the relevant packet is sent to a next stage Banyan network, but when the misroute check tag is not set, the relevant packet is outputted to an output module connected to a desired output. The input module stores a packet from the input port and a packet from a misroute tag check part and sends one of these packets selectively to a succeeding Banyan network.

摘要： In a method for coding a moving picture image, in which the moving picture image is coded into a digital moving picture stream when the moving picture image is transmitted via a network, the moving picture image is coded in such a manner that a data unit including a synchronous signal corresponds or conforms to a data transmission unit on the network, or, the moving picture image is coded in such a manner that a synchronous signal is included in a position near a head of respective data transmission units on the network. Therefore, in the digital moving picture stream generated according to the invention, the header of the synchronous layer is included in every maximum length of the IP packet in the variable length packet switching method and in every size of the time slots in the variable bit rate TDM.

摘要： An input distribution packet switch network includes a plurality of 2×2 switch elements and packet input modules for the switch network. The switch elements are arranged in multistage and connected in accordance with Shuffle type topology to constitute a N×N switch network (N=2k, k: integer number of 2 and over). The links of the leftmost and rightmost switch elements are connected to one another so that the N×N switch network can have a ring architecture. The packet input modules are distributed laterally in the switch network.
