Verfahren für die Wiederzuweisung von Kanälen während einer Übertragung von Isochronen IEEE-1394 Daten an ein äußeres synchrones Netz und Vorrichtung dafür

摘要

A method for reassigning channels during the transmission of IEEE-1394 isochronous data to an external synchronous network and an apparatus therefor are provided. The method for reassigning channels during the transmission of isochronous data from the IEEE-1394 network to an external synchronous network includes the steps of (a) forming a mapping table showing the relationship between the channels of the IEEE-1394 network and the channels of the external synchronous network when a call is set with respect to the external synchronous network, (b) reading the channel order from the header of the isochronous data to be transmitted, (c) reassigning the channel order of the IEEE-1394 network according to the channel order of the external synchronous network with reference to the mapping table, and (d) transmitting the isochronous data to the external synchronous network according to the reassigned channel order.
