ABSTRACT:
A transmission apparatus inserts unit signals into a stream transmitted from a first transmission path having a first bandwidth to a second transmission path having a second bandwidth. The insertion is controlled by an assignment signal that is generated by the following steps, which are repeated cyclically at intervals equivalent to the unit-signal length: a value representing the second bandwidth is added to a selected value; the sum is compared with a threshold; the assignment signal is set or reset according to the comparison result; the threshold value is subtracted from the sum to obtain a difference; and either the sum or the difference is selected, according to the assignment signal, as the selected value. This scheme enables bandwidth to be distributed evenly, thus reducing processing and memory requirements.
