Abstract

During the transmission of data packets received on a wired connection via a first interface via a second interface designed for the wireless transmission of data, the problem exists that between receiving the data and transmitting the data via the second interface a relatively large delay time can arise which must be bridged by means of a suitably dimensioned buffer memory. To enable the maximum delay time to be further reduced, the necessary processing of the received IEEE 1394 bus packets is already performed section by section immediately after a received data packet has arrived. After the complete number of bus packets falling within a transmission frame has been received, there is therefore no longer any lengthy processing time required and the probability of missing the time slots reserved in the next transmission frame is significantly reduced. The buffer memory for bridging the delay time period can therefore be correspondingly smaller.
