Abstract:
1. A method for multiplexing data from a plurality of input channels that can differ in data phase and/or bit rate into a serial signal comprising the steps of: storing the data, respectively arriving from the plurality of input channels, into separate memories respectively; and retrieving data from the respective memories in a predetermined order, and multiplexing the data, together with timing data indicating the presence of the data, into a serial signal of a frame structure having time slots fixedly assigned to the respective input channels, wherein a plurality of first bit storing positions and the same number of second bit storing positions are assigned for one bit of data, and the same value as the value of the data is stored in each of the plurality of first bit storing positions while, in the plurality of second bit storing positions, timing data whose value changes is stored when the data exists, but timing data whose value does not change is stored when the data does not exist.
