<p><P>PROBLEM TO BE SOLVED: To increase the reliability of different input data streams. <P>SOLUTION: A data transmitting node comprises: a plurality of buffers for buffering data from a respective plurality of input data streams; means for monitoring an occupancy level of each of the plurality of buffers to detect if the occupancy level is sufficient to provide a complete data block to the transmission stream; and a transmission controller operable to select, in turn, a buffer from the plurality of buffers to output a data block to a transmission data stream, according to a buffer selection order. In the data transmitting node, if the buffer selected by the transmission controller is detected to have an insufficient occupancy level when selected, a dummy data block is supplied to the data transmission stream in place of a data block from the selected buffer. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
